Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a seed-mixed compost composition and a method for producing the same, and more specifically to seeds which have a high germination rate and antibacterial activity and which can be easily planted at low cost. The present invention relates to a mixed compost composition and a method for producing the same.

[0002]

2. Description of the Related Art Organic waste such as manure of livestock, raw waste such as leftover food, and sewage sludge have been conventionally treated by landfill treatment, etc., but due to the growing interest in environmental protection in recent years, Fermentation of such organic wastes with microorganisms is becoming common. This is because the rotten substance thus obtained can be used as compost.

That is, when the organic waste is fermented, a reusable compost can be obtained as a soil improver or a natural fertilizer to be spread on a farm site, or as a gardening product in a general household. In other words, organic waste can be used as a reusable resource. And in this case,
Since the amount of organic waste to be landfilled is remarkably reduced, there is no need to secure land for landfill, so that the treatment cost can be reduced and it is also preferable from the viewpoint of environmental protection.

However, the amount of organic waste to be treated is extremely large. Therefore, when the compost is obtained on an industrial scale as described above, the production amount greatly exceeds the consumption amount. In short, compost will be oversupplied,
In addition to the need for capital investment to install a large-scale storage facility, it is difficult to recover the amount of money that corresponds to the amount of investment because a large amount of excess inventory is accumulated.

Therefore, various studies have been made on the utilization of compost other than farm land. For example, JP 2000-11
Japanese Patent No. 9086 proposes that plant seeds are attached to the surface of a molded article obtained by molding compost into a plate shape, and shipped in this state. The publication also suggests that this molded article can be used for greening.

[0006]

By the way, Japanese Unexamined Patent Application Publication No.
In the method described in Japanese Patent Publication No. 0-119086, seeds are attached to the compost. However, in this case, the concentration of nutrients such as nitrogen, phosphorus and potassium contained in the compost becomes excessive, which may prevent germination of the seeds. That is, the above method has a problem that the germination rate of seeds is not good.

Moreover, in this method, the compost is dried after the seeds are attached. In such a procedure, the seeds are deprived of water and excessively dried, which makes it extremely difficult to germinate depending on the type of plant.

The present invention has been made in order to solve the above-mentioned problems, and has a good germination rate even when compost is mixed, and moreover, it is possible to carry out greening easily and simply, and further, pesticides It is an object of the present invention to provide a seed-mixed compost composition capable of remarkably reducing the use amount of and a manufacturing method thereof.

[0009]

In order to achieve the above object, the present invention provides a compost and peat moss in a weight ratio of 30: 30.
70 to 50:50 are mixed, and the water content is 15
It is characterized in that the seeds of plants are mixed with the compost composition of not more than wt%.

In the present invention, organic waste such as manure, waste food and sewage sludge is reused as a greening resource in the form of compost. Therefore, the production amount and the consumption amount of compost can be balanced. Therefore, it is not necessary to reclaim organic waste from the landfill, which can reduce the burden on the environment, and it is not necessary to install a large-scale storage facility, resulting in high capital investment costs. Avoided. Further, it is possible to reduce the processing cost of organic waste.

Moreover, the seed-mixed compost composition according to the present invention can be leveled by an easy and simple operation in which the seed-mixed compost composition is spread on the soil and then crushed. That is, since the greening can be easily performed in a short period, the work cost can be reduced.

Then, by mixing the peat moss in the above proportion to adjust the concentration of the fertilizer component contained in the compost, the germination rate of the seeds can be improved.

When the water content exceeds 15% by weight,
Since the seeds germinate in a relatively short period of time, it becomes difficult to store them for a long period of time.

Here, the C / N ratio of the compost is preferably 25 or less. When the C / N ratio exceeds 25, nitrogen tends to be insufficient, which may hinder the growth of plants.

The kind of seed is not particularly limited, but a suitable example is turf seed generally used for greening.

The seed-mixed compost composition according to the present invention may be a simple mixture of compost, peat moss and seeds, or may be a molded product in which the compost and peat moss are fixed to each other with starch paste as a binder. In this case, only the work of laying it on the soil needs to be performed, and therefore the work efficiency is further improved. In other words, the work cost can be further reduced.

Here, when the seed is of a type that requires light for germination, the embedding position (depth) of the seed
Should be within 0.5 cm from one end surface of the molded product.

Further, according to the present invention, the compost having a water content of 15% by weight or less and peat moss are in a weight ratio of 30: 70-5.
The mixture is mixed at a ratio of 0:50, or the compost and peat moss are mixed at a weight ratio of 30:70 to 50:50, and then the water content is adjusted to 15% by weight or less to obtain a compost composition. It is characterized by having 1 step and a 2nd step of mixing plant seeds with the compost composition.

Thus, a seed-mixed compost composition obtained by simply mixing the compost, peat moss and seeds is obtained.

When the seed-mixed compost composition is produced as a molded article, a third step of adding starch paste to the compost composition after the second step, and a step of adding starch paste The fourth step of pressurizing and molding the mixed seed compost composition may be performed.

When a molded product containing plant seeds that require light for germination is produced, the water content is 15% by weight.
The weight ratio of the following compost and peat moss: 30: 70-
The mixture is mixed at a ratio of 50:50, or the compost and peat moss are mixed at a weight ratio of 30:70 to 50:50, and then the water content is adjusted to 15% by weight or less to obtain a compost composition. 1, a second step of adding starch paste to the compost composition, a third step of pressurizing the compost composition to which the starch paste has been added to form a primary molded article, and the third step. After sowing plant seeds on the surface of the primary molded article, a mixture of soil or compost and peat moss in a weight ratio of 30:70 to 50:50 with a thickness of 0.5 cm or less is prepared on the seeds. The soil of which the seeds of plants were mixed on the surface of the compost composition which was swelled or molded was mixed with peat moss at a weight ratio of 30:70 to 50:50 to obtain a thickness of 0. The fourth step of filling the soil under 5 cm and the soil There can be produced by a production method having a fifth step of the second molded product by pressurizing and the said compost composition primary molded article.

In this case, plant seeds may be mixed with the compost composition obtained in the first step. This seed shall be a plant that does not particularly require light for germination.

In any of the above-mentioned production methods, it is preferable to separately classify the compost and the peat moss whose moisture has been adjusted, and then mix them. This is because the compost and the peat moss can be mixed almost uniformly.

[0024] Preferable examples of compost include fermented manure, waste food or sewage sludge, but is not particularly limited thereto, and fermented organic waste is used. It may be any one obtained by.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of a mixed seed compost composition and a method for producing the same according to the present invention will be described in detail with reference to the accompanying drawings.

The seed-mixed compost composition according to the first embodiment of the present invention comprises a mixture of compost and peat moss (hereinafter referred to as a compost composition) mixed with plant seeds.

The compost is not particularly limited, but preferred examples include those obtained by fermenting manure, waste food, sewage sludge and the like, as described later.

The compost contains nitrogen, phosphorus and potassium which are nutrient sources required for plant development. That is, compost is a fertilizer component that promotes plant growth. Among these, nitrogen is contained as an ammonium salt or a nitrate, and the nitrate nitrogen is finally converted into an amino acid through the ammonia nitrogen in the plant body to become a protein or the like. Also, phosphorus is contained as a phosphate, and after being absorbed into the plant,
It aggregates at the active growth site and is provided as a constituent component of nucleic acids, nuclear proteins, phospholipids and the like. The potassium contained as potassium oxide is mainly present in the plant body in an ionic state, and contributes to the osmotic action in cells, the protein synthesis action, and the sugar translocation action.

The compost further contains calcium, which suppresses the appearance of disorders such as core rot, and magnesium, which functions as an enzyme activator and is involved in photosynthesis, as calcium salts and magnesium salts, respectively.

Carbon-nitrogen ratio (C / N ratio) in compost
Is preferably 25 or less. In other words, the compost is preferably a ripe product. When it exceeds 25, the nitrogen tends to be insufficient, so that the leaves of the germinated plant show a yellow color or the growth tends to decline.

When the above-mentioned salts contained in the compost are excessively present, germination of seeds is suppressed. Pete moss is a component for avoiding a decrease in the germination rate of seeds due to the presence of excess salt, and is mixed with compost to adjust the salt concentration within an appropriate range. That is, peat moss has an action of suppressing salt concentration disorders (so-called salt accumulation) due to compost. On the other hand, peat moss imparts water retention to the seed-mixed compost composition because it is highly water absorbent.

Here, the peat moss is a product in which sphagnum moss has corroded and is commercially available at a low cost. Therefore, the price of the seed-mixed compost composition does not increase due to the mixing of peat moss.

The ratio of compost and peat moss is 30:70.
˜50: 50 (weight ratio, the same applies hereinafter). When the amount of compost is less than 30 parts by weight, the seeds inoculate from the compost have a shortage of nutrients, and the germination rate decreases. On the other hand, when it exceeds 50 parts by weight, salting occurs and the germination rate decreases as described above.

The water content of the compost composition comprising compost and peat moss is set to 15% by weight or less. If the water content exceeds 15% by weight, germination occurs before shipping the seed-mixed compost composition or before spreading it on the soil, and eventually the germination rate after spreading becomes low. When the water content is 15% by weight or less, the seed does not germinate for about 6 months.

The seeds mixed with the compost composition are spread on the soil and crushed, and then germinated by supplying water and, if necessary, light. Then, it grows as a plant and greens the vicinity.

The type of plant is not particularly limited, but a suitable example is turf which is widely used for greening. The types of grass include fescue, bent grass, blue grass, and the like, but it goes without saying that other kinds of grass may be used.

The number of seeds mixed with the compost composition is set according to the volume of seeds and the area to be greened. In the case of turf seeds, it is generally sufficient to mix about 20 g with 20 liters of the compost composition per 1 m ² of construction.

The seed-mixed compost composition has an antibacterial ability derived from compost. Specifically, pythium
The growth of Pythium bacteria that causes the disease is suppressed. Therefore, the disease on the grass is significantly suppressed.

The seed-mixed compost composition according to the first embodiment is packaged as a mixture of the above-mentioned compost, peat moss and seeds, and then distributed. When this seed-mixed compost composition is used for greening, for example, the seed-mixed compost composition may be spread over the spread soil in a thickness of 2 to 3 cm, and the soil may be crushed to level the soil. That is, it is not particularly necessary to disinfect the soil, spray the basic fertilizer, or raking. Therefore, greening can be performed easily and easily.

When the cultivated seed-mixed compost composition is exposed to water and, if necessary, light at the same time, germination from seeds occurs. The germination rate of seeds is 60% or more for turf even if 6 months have passed after shipment. In addition, the period until germination is shorter than that in the case of using a commercially available mixture of grass soil and chemical fertilizer.

Moreover, the germination of plants is remarkably suppressed from becoming sick. This is because the compost composition has an antibacterial activity as described above, and thus the growth of pathogenic bacteria is significantly suppressed. Therefore, the amount of pesticide sprayed can be significantly reduced. Furthermore, the degree of growth of the germinated root area is about 1.5 to 2 times better than that when a chemical fertilizer is used.

Next, the seed mixed compost composition according to the second embodiment will be described. This seed-mixed compost composition is a molded product obtained by molding the seed-mixed compost composition according to the first embodiment into a predetermined shape such as a plate.

Here, it is difficult to secure the strength of the molded product only by pressurizing the seed-mixed compost composition according to the first embodiment. Therefore, the compost and peat moss are fixed by using starch paste as a binder. Starch itself is a substance originally derived from plants such as wheat, rice, corn, potato, etc. Therefore, even if it is used as a binder, it does not cause environmental pollution.

The molded product in which the compost and peat moss are fixed by the starch paste has a small specific gravity. That is, the first
If the seed-mixed compost composition according to the embodiment has the same weight, the volume is small. Therefore, in the distribution stage, a larger amount of the seed-mixed compost composition according to the first embodiment can be transported, and eventually, the transportation cost can be reduced.

In addition, when the molded product is spread on the soil, the molded product may be placed on the soil, and no crushing is required. That is, greening becomes easier and simpler.

Germination from seeds occurs by applying water, and optionally light, as described above. Of course, also in this case, the germination rate of seeds is 60% or more, the growth condition of the root zone is good, and it is possible to avoid causing a disease.

Here, if the seed is a plant of a type that requires light for germination, the seed embedding position in the molded product is preferably within 0.5 cm from one end surface of the molded product. When seeds are embedded at a position deeper than 0.5 cm, it becomes difficult for light to reach, so that germination does not proceed smoothly. In this case, needless to say, seeds of a plant that does not particularly require light during germination may be embedded at a position deeper than 0.5 cm. In either case, the seeds may be placed on the soil with the side on which the seeds are embedded facing up.

These seed-mixed compost compositions can be manufactured as follows.

First, the method for producing the seed-mixed compost composition according to the first embodiment will be described. As shown in the flowchart in FIG. 1, this manufacturing method includes a preparatory step Ssub1 for obtaining compost, a first step S1 for mixing compost and peat moss to form a compost composition, and mixing seeds of plants with the compost composition. And a second step S2.

In the preparation step Ssub1, so-called composting is carried out, in which manure, sewage sludge, waste food, etc. are fermented to form compost. This fermentation treatment may be an anaerobic treatment, but since the chemical oxygen demand (COD) can be removed with high efficiency in a relatively short time,
Aerobic treatment is preferred. For the above reason, it is preferable to continue the fermentation treatment until the C / N ratio of the compost becomes 25 or less.

The compost may be mixed with peat moss as it is to form a compost composition, and then the water content of the compost composition may be adjusted. However, the water content is adjusted first, and then classified using a sieve, and then mixed. Is preferred. As the size distribution range of compost is narrowed by performing classification, compost,
This is because the mixing ratio of peat moss and seed can be made substantially uniform. In other words, a more homogeneous seed mixed compost composition can be obtained. Compost with high water content has high viscosity and is difficult to classify. Further, when compost having a high water content is mixed with peat moss, the peat moss absorbs water, which makes it difficult to adjust the water content.

On the other hand, it is preferable to classify peat moss in advance using a sieve. This narrows the particle size distribution range of peat moss, and thus a more homogeneous seed-mixed compost composition can be obtained.

Next, in the first step S1, the compost and peat moss whose moisture has been adjusted are converted into compost: peat moss =
Mix at 30:70 to 50:50 to obtain a compost composition.
As described above, when the amount of compost is less than 30 parts by weight or more than 50 parts by weight, plant growth inhibition or salt accumulation occurs and the germination rate decreases. As a mixing method, a known technique such as using a rotary mixer can be adopted.
If each of the compost and peat moss is classified in advance,
Both are mixed substantially uniformly with each other.

Next, in the second step S2, the seed mixed compost composition according to the first embodiment is obtained by mixing plant seeds with this compost composition. The amount of seeds may be set according to the volume of the seeds and the area of greening, but in the case of turf seeds, it is mixed at a ratio of about 20 g with respect to 20 liters of the compost composition per 1 m ² of construction. It is enough. Also in the mixing of seeds in the second step S2,
Similar to the above, it can be performed by a known technique.

The obtained seed-mixed compost composition according to the first embodiment is packaged in bags and then shipped and distributed. When the seeds contained in the seed-mixed compost composition are germinated, the seeds may be spread on the soil and then watered. Excess water is absorbed by peat moss, so that root rot of the plant can be avoided. Further, when the temperature is high, the water absorbed by peat moss is released and supplied to the plant, so that it is possible to avoid the lack of water in the plant body.

The seed-mixed compost composition (molded article) according to the second embodiment is manufactured by molding the seed-mixed compost composition according to the first embodiment obtained as described above into a predetermined shape. be able to. That is, the method for producing a seed-mixed compost composition according to the second embodiment, as shown in FIG. 2, includes a third step S3 of adding starch paste and a seed-mixed compost composition after the second step S2. The fourth step S4 of pressurizing and molding is added.

The amount of starch paste used in the third step S3 is set according to the concentration and viscosity of the starch paste. For example, when corn starch having a concentration of 1% by weight is used, the amount is 10 per 100 parts by volume of the seed mixed compost composition.
It can be added in a proportion of part by volume. After adding the starch paste, the starch paste is dispersed substantially uniformly by stirring the seed mixed compost composition.

Next, in the fourth step S4, a seed-mixed compost composition in which starch paste is substantially uniformly dispersed is molded. The molding is performed as follows using a mold, for example. That is, the seed-mixed compost composition filled in the formwork having a bottom is pressed by a press plate of a pressure press machine to be solidified, and the seed-mixed compost composition is aggregated.

The pressing pressure at this time is 0.15 to 0.5.
It is preferably set to MPa. If it is less than 0.15 MPa, the strength of the molded seed-mixed compost composition may not be sufficient. If it exceeds 0.5 MPa, the seed may be crushed.

Then, the starch paste contained in the aggregated seed-mixed compost composition is dried to fix the compost and peat moss, whereby the seed-mixed compost composition according to the second embodiment has a shape corresponding to the shape of the mold. The thing is obtained.
The drying temperature and time are set within a range in which the starch paste can be efficiently dried and cracks and cracks in the molded product can be avoided. For example, 40 ℃
In the case of ventilation drying with, by leaving it for about 24 hours, it is possible to reliably obtain a molded product without cracks or cracks.

The seed-mixed compost composition in which seeds that require light for germination are mixed can be manufactured by the manufacturing method whose flow chart is shown in FIG. 3 apart from the above. That is, in this manufacturing method, a first step S10 of obtaining a compost composition, a second step S20 of adding starch paste to the compost composition, and the compost composition containing starch paste as a primary molded article. A third step S30, a fourth step S40 of arranging plant seeds on the surface of the primary molded article together with soil or a compost composition, and the soil or compost composition and the primary molded article. And a fifth step S50 of applying pressure.

The first step S10 is the above-mentioned first step S1.
It is done according to. In short, by mixing the compost obtained in the preparation step Ssub1 with peat moss,
A compost composition is made.

Next, in the second step S20, the third step S
Add starch glue to the compost composition according to 3. Here, the compost composition may be mixed with seeds of a plant that can germinate without particularly requiring light.

After adding starch paste and stirring, in the third step S30, the compost composition is pressed in accordance with the fourth step S4 to obtain a primary molded article. The upper limit of the pressing pressure at this time is not particularly limited, but it is preferably 0.5 MPa when seeds are mixed in the compost composition. This is because, as described above, it is feared that the seed will be crushed if the pressing pressure exceeds 0.5 MPa.

Then, in a fourth step S40, plant seeds are sown on one end surface (surface) of the primary molded product. As described above, this seed is a seed of a plant that requires light for germination.

Then, soil is laid on the seeds. Alternatively, the compost composition may be placed in place of soil. In any case, the thickness is within 0.5 cm so that the seeds can reach the light. That is, the position of the seed should not be deeper than 0.5 cm.

Here, in the fourth step S40, instead of sowing seeds on the primary molded product, soil in which seeds are premixed may be laid on the primary molded product. Alternatively, the compost composition in which seeds are premixed, that is,
A mixture in which the compost and peat moss are mixed at 30:70 to 50:50 may be placed on the primary molded product.
In this case, the thickness of the soil or compost composition may be 0.5 cm or less. Thereby, the position of the seed can be set to 0.5 cm or less from the surface.

Finally, in the fifth step S50, the filled soil or compost composition and the primary molded product are pressurized to form a secondary molded product, which is used as a second product.
The seed mixed compost composition according to the embodiment is obtained.
The pressing pressure at this time is preferably 0.15 to 0.5 MPa in order to avoid crushing the seeds.

According to the embodiment described above, compost can be effectively used as a resource for greening. Therefore, the amount of compost consumed increases, so that the amount of production and the amount of consumption can be balanced. Therefore, it is possible to eliminate the need to provide a large-scale storage facility, in other words, the need to invest a large amount of equipment installation cost.

[0070] Further, in the work for greening, it suffices to spread the above-mentioned seed-mixed compost composition on the soil and carry out the crushing if necessary. Therefore, it is possible to carry out the greening simply and easily and quickly. it can. Therefore, the cost required for greening can be reduced. In addition, when greening the area where the lawn has withered, for example, after cutting the area, the seed-mixed compost composition according to the second embodiment may be placed on the exposed soil.

[0071]

[Example] Cattle manure or sewage sludge was fermented by aerobic treatment to obtain a mature compost having a C / N ratio of 24.2 and 20.1. Then, after adjusting the water content of each compost to 15% by weight, the compost was classified using a 10 mm mesh sieve. On the other hand, peat moss was also classified using a 10 mm mesh sieve, and those that passed through the sieve were mixed at various weight ratios to prepare a compost composition.

Then, seeds of fescue, bentgrass, and bluegrass were stirred and mixed into the obtained compost composition to prepare a seed-mixed compost composition, and water was supplied to examine the germination rate of the seeds. Note that this test was performed twice for those using compost derived from cow manure.

For comparison, a control test was conducted using a commercially available mixture of grass soil for soil and chemical fertilizer (hereinafter referred to as control) and compost, respectively. The results are also shown in FIG. It is clear from FIG. 4 that the seed-mixed compost composition germinates seeds better than the control or compost.

Next, the antibacterial activity of the seed mixed compost composition was investigated. Specifically, the seed-mixed compost composition and the control were inoculated with purified water containing 10 ⁴ CFU / ml of Pythium bacteria, and the temperature was 22 ° C and the humidity was 60% in an artificial weather machine.
The growth condition of the turf was examined under the conditions. As the compost composition, a compost in which cow manure was fermented and peat moss was mixed at 50:50 was used.

For comparison, an aqueous solution of azoxystrobin wettable powder diluted 4000 times was used as a pesticide.
And sprayed at a rate of ^{5ml / m 2, 250ml / m} 2, 500ml / m 2 were grown grass under the conditions described above, was examined the relationship between the development status and application rates.

First, the germination rate after 28 days was 81% in the case of the seed mixed compost composition in which Pythium fungus was not inoculated and the pesticide was not used, while the Pythium fungus was inoculated. Then, it was almost equal to about 82 to 85% regardless of the amount of pesticide sprayed. On the other hand, in the control, the germination rate was 65.3% in the control in which Pythium bacteria were not inoculated and the pesticide was not used, whereas 43.0% in the case where the pesticide was not used and the pesticide was used. In case of 125ml / m ² 44.3%, 250m
57.0% at 1 / m ² , 47.3% at 500 ml / m ^2.
And both of them were lower than those not inoculated with Pythium.

Next, FIG. 5 shows the disease incidence of turf after germination. As can be seen from FIG. 5, in the seed-mixed compost composition, the disease incidence is almost constant regardless of the amount of pesticide applied, whereas in the control, the disease incidence increases as the amount of pesticide applied decreases. Showed a tendency to Also, even if a standard amount (500 ml / m ² ) of pesticide is used,
The disease incidence did not fall below the disease incidence in the mixed seed compost composition.

From the above results, when the plant is grown using the seed-mixed compost composition, the germination rate can be secured without the use of pesticides, while the disease incidence rate can be suppressed. Thus, it is clear that the amount of pesticide used can be significantly reduced.

[0079]

As described above, according to the present invention,
Organic waste such as manure, waste food, and sewage sludge can be reused as a greening resource in the form of compost. Therefore, the production amount and the consumption amount of the compost can be balanced, so that the necessity of landfilling the organic waste and the necessity of providing a large-scale storage facility are eliminated. Therefore,
It is possible to reduce the burden on the environment and to avoid high capital investment costs.

Further, since the peat moss is mixed at a predetermined ratio in the seed mixed compost composition according to the present invention, the concentration of the fertilizer component in the compost is adjusted. Moreover, since peat moss has excellent water retention, seeds are not excessively dried. Therefore, the germination rate of seeds is improved.

Moreover, the seed-mixed compost composition can be leveled by an easy and simple operation of spreading the seeds on the soil and then suppressing the pressure. If it is a molded product, it is not necessary to carry out compression. That is, since the greening can be easily performed in a short period of time, the working cost for the greening can be reduced.

Further, this seed-mixed compost composition has antibacterial activity. Therefore, the germination rate of the plant is good,
And the illness rate is small. Therefore, the amount of pesticide used can be significantly reduced, and the effect of further reducing the load on the environment is achieved.
