Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seed mixed compost composition and a method for producing the same, and more specifically, a seed mixed compost composition having a high germination rate and antibacterial activity, and capable of greening at a low cost and easily. Regarding the method.
[0002]
[Prior art]
Organic waste such as livestock manure, raw food such as leftovers and sewage sludge has been treated by landfill treatment. However, due to the recent growing interest in environmental protection, It is becoming common to ferment wastes with microorganisms. This is because the ripening substance thus obtained can be used as compost.
[0003]
That is, when organic waste is fermented, compost that can be reused as a soil conditioner or natural fertilizer spread on farm land, or as a gardening article in a general household can be obtained. In other words, organic waste can be made a reusable resource. Moreover, in this case, since the amount of organic waste to be landfilled is remarkably reduced, it is not necessary to secure a landfill site, so that the processing cost can be reduced, and it is preferable from the viewpoint of environmental protection. I can say that.
[0004]
However, the amount of organic waste to be treated is extremely large. For this reason, when compost is obtained on an industrial scale as described above, its production amount greatly exceeds the consumption amount. In short, since compost is oversupplied, capital investment costs are required to establish a large-scale storage facility, and it is difficult to recover the amount commensurate with the amount of investment due to the accumulation of a large amount of excess inventory. It becomes.
[0005]
Therefore, various studies have been made on using compost other than farm land. For example, Japanese Patent Application Laid-Open No. 2000-119086 proposes that plant seeds are attached to the surface of a molded product obtained by molding compost into a plate shape and shipped in this state. The publication also suggests that this molded body can be used for greening.
[0006]
[Problems to be solved by the invention]
By the way, in the method described in Japanese Patent Application Laid-Open No. 2000-119086, seeds are attached to compost. However, in this case, the concentration of nutrients such as nitrogen, phosphorus, and potassium contained in the compost becomes excessive, which may inhibit the germination of the seeds. That is, in the above method, a problem that the germination rate of seeds is not good is obvious.
[0007]
Moreover, in this method, the compost is dried after the seeds are attached. In such a procedure, the seeds are deprived of moisture and dried excessively, so that germination becomes extremely difficult depending on the type of plant.
[0008]
The present invention has been made to solve the above-described problems, and even when compost is mixed, the germination rate is good, and it is possible to easily and simply replant, and further, the amount of agricultural chemical used. An object of the present invention is to provide a seed mixed compost composition and a method for producing the same.
[0009]

For this reason, it is possible to achieve a balance between compost production and consumption. Therefore, it becomes unnecessary to landfill organic waste, so that the burden on the environment can be reduced, and it is not necessary to provide a large-scale storage facility, so that the capital investment cost can be high. Avoided. Moreover, the processing cost of organic waste can also be reduced.
[0011]
Moreover, the seed-mixed compost composition according to the present invention can be leveled by an easy and simple operation of crushing after spreading on the soil. That is, since the greening can be easily performed in a short period of time, the operation cost can be reduced.
[0012]
And the germination rate of a seed can be made favorable by mixing peat moss in said ratio and adjusting the density | concentration of the fertilizer component contained in compost.

In any of the manufacturing methods described above, it is preferable that the compost having been subjected to moisture adjustment and peat moss are classified separately and then mixed. This is because compost and peat moss can be mixed substantially uniformly.
[0024]
Suitable examples of compost include fermented manure, waste food or sewage sludge, but are not particularly limited to these, and can be obtained by fermenting organic waste. Anything can be used.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a seed mixed compost composition and a production method thereof according to the present invention will be described in detail with reference to the accompanying drawings.
[0026]
The seed mixed compost composition according to the first embodiment of the present invention is obtained by mixing plant seeds with a mixture of compost and peat moss (hereinafter referred to as a compost composition).
[0027]
The compost is not particularly limited, but suitable examples include those obtained by fermenting manure, waste food, sewage sludge, or the like, as described later.
[0028]
Compost contains nitrogen, phosphorus, and potassium, which are nutrient sources necessary for plant growth. That is, compost is a fertilizer component that promotes plant growth. Among these, nitrogen is contained as an ammonia salt or nitrate, and nitrate nitrogen is finally converted into an amino acid through ammonia salt nitrogen in the plant body to become a protein or the like. Phosphorus is contained as a phosphate, and after being absorbed into the plant body, it collects at a site where growth is active and serves as a constituent component such as nucleic acid, nucleoprotein, and phospholipid. Potassium contained as potassium oxide exists mainly in an ionic state in the plant body, and contributes to osmotic pressure action, protein synthesis action, and sugar translocation action in cells.
[0029]
The compost further contains calcium, which suppresses the occurrence of obstacles such as core rot, and magnesium that functions as an enzyme activator and participates in photosynthesis as calcium salt and magnesium salt, respectively.
[0030]
The carbon-nitrogen ratio (C / N ratio) in compost is preferably 25 or less. In other words, the compost is preferably a mature product. If it exceeds 25, nitrogen tends to be deficient, so the leaves of germinated plants tend to appear yellow or the growth tends to decline.
[0031]
In addition, when each said salt contained in compost exists excessively, germination of a seed comes to be suppressed. Peat moss is a component for avoiding a decrease in seed germination rate due to the presence of excess salts, and is mixed with compost to adjust the salt concentration within an appropriate range. That is, peat moss acts to suppress salt concentration disturbance (so-called salt accumulation) due to compost. On the other hand, peat moss provides water retention to the seed-mixed compost composition because of its high water absorption.
[0032]
Here, peat moss is eroded by sphagnum and is commercially available at a low price. For this reason, the price of a seed mixed compost composition does not rise with mixing peat moss.
[0033]
The ratio of compost and peat moss is set within a range of 30:70 to 50:50 (weight ratio, hereinafter the same). When the compost is less than 30 parts by weight, the germination rate is lowered because the nutrients seeds inoculate from the compost are insufficient. Moreover, when it exceeds 50 weight part, as mentioned above, salt volume generate | occur | produces and a germination rate falls.
[0034]
Moreover, the moisture content of the compost composition composed of compost and peat moss is set to 15% by weight or less. This is because if the water content exceeds 15% by weight, germination occurs before the seed-mixed compost composition is shipped or before it is spread on the soil, and eventually the germination rate after the spread is lowered. When the moisture content is 15% by weight or less, the seeds do not germinate for about 6 months.
[0035]
The seeds mixed with the compost composition are laid on the soil and subjected to repression, and then germinate by being supplied with moisture and, if necessary, light. And it grows as a plant and greens the neighborhood.
[0036]
Although the kind of plant is not specifically limited, As a suitable example, the lawn widely used in the case of greening can be mentioned. Examples of the type of turf include fescue, bentgrass, bluegrass and the like, but of course other types of turf may be used.
[0037]
The number of seeds mixed with the compost composition is set according to the volume of seeds and the area to be greened. For turf seeds, generally 1m²It is sufficient to mix at a rate of about 20 g with respect to 20 liters of compost composition for the hit construction.
[0038]
This seed mixed compost composition has antibacterial activity derived from compost. Specifically, the growth of Pythium causing causative pythium disease is suppressed. Therefore, it is remarkably suppressed that a disease is brought to a lawn.
[0039]
The seed mixed compost composition according to the first embodiment is distributed after being packaged as a mixture in which the above-mentioned compost, peat moss and seeds are mixed. When greening is performed using the seed mixed compost composition, for example, the seed mixed compost composition may be spread on a spread soil so as to have a thickness of 2 to 3 cm, and further pressed to level the ground. That is, it is not particularly necessary to disinfect soil, spray fertilizer, and raking. For this reason, it becomes possible to perform greening easily and simply.
[0040]
When water is applied to the prepared seed mixed compost composition and, if necessary, light at the same time, germination from the seed occurs. In the case of turf, the germination rate of seeds is 60% or more even if 6 months have passed since shipment. In addition, the period until germination is shorter than that in the case of using a commercially available mixture of turf earth soil and chemical fertilizer.
[0041]
Moreover, it is remarkably suppressed that the germinated plant becomes sick. This is because, as described above, the compost composition has antibacterial activity, so that the growth of pathogenic bacteria is remarkably suppressed. Therefore, the amount of agricultural chemicals applied can be significantly reduced. Furthermore, the degree of growth of the germinated root region is about 1.5 to 2 times better than when chemical fertilizer is used.
[0042]
Next, the seed mixed compost composition according to the second embodiment will be described. This seed mixed compost composition is a molded product formed by molding the seed mixed compost composition according to the first embodiment into a predetermined shape such as a plate shape.
[0043]
Here, it is difficult to ensure the strength of the molded article only by pressurizing the seed mixed compost composition according to the first embodiment. For this reason, compost and peat moss are fixed by using starch paste as a binder. Starch itself is a substance derived from plants such as wheat, rice, corn, potato and the like, and therefore does not cause environmental pollution even when used as a binder.
[0044]
Molded articles in which compost and peat moss are fixed by starch paste have a low specific gravity. That is, if the weight is the same as the seed mixed compost composition according to the first embodiment, the volume is small. For this reason, in a distribution | circulation stage, it can be transported in large quantities compared with the seed mixed compost composition which concerns on 1st Embodiment, and a transport cost can be reduced after all.
[0045]
Moreover, when this molded product is laid on the soil, the molded product may be placed on the soil, and no pressure reduction is required. That is, it becomes easier and simpler to perform greening.
[0046]
Germination from the seed occurs by applying water, and if necessary, 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 avoided that diseases are caused.
[0047]
Here, if the seed is a plant of a kind 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 germination does not proceed smoothly. In this case, it goes without saying that the seeds of plants that do not 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 where the seeds are embedded facing up.
[0048]
These seed mixed compost compositions can be produced as follows.
[0049]
First, a method for producing a seed mixed compost composition according to the first embodiment will be described. As shown in the flow chart of FIG. 1, this manufacturing method includes a preparation step Ssub1 for obtaining compost, a first step S1 for mixing compost and peat moss to obtain a compost composition, and mixing the seeds of the plant with the compost composition. And a second step S2.
[0050]
In the preparatory step Ssub1, so-called composting is performed, in which manure, sewage sludge, waste food, and the like are composted by fermentation. This fermentation process may be an anaerobic process, but an aerobic process is suitable because chemical oxygen demand (COD) can be removed with high efficiency in a relatively short time. For the reasons described above, the fermentation treatment is preferably continued until the compost C / N ratio is 25 or less.
[0051]
The compost may be mixed with peat moss as it is to make a compost composition, and then the water content of the compost composition may be adjusted. preferable. This is because the particle size distribution range of compost is narrowed by classification, so that the mixing ratio of compost, peat moss and seeds can be made substantially uniform. In other words, a more homogeneous seed mixed compost composition can be obtained. Compost with high moisture content has high viscosity and is difficult to classify. In addition, when compost having a high water content is mixed with peat moss, peat moss absorbs moisture, making it difficult to adjust moisture.
[0052]
On the other hand, it is preferable to classify peat moss in advance using a sieve. Thereby, the particle size distribution range of peat moss is narrowed, so that a more homogeneous seed mixed compost composition can be obtained.
[0053]
Next, in the first step S <b> 1, the compost whose moisture has been adjusted and peat moss are mixed in compost: peat moss = 30: 70 to 50:50 to obtain a compost composition. As described above, in any case where the compost is less than 30 parts by weight or more than 50 parts by weight, plant growth inhibition or salt volume occurs and the germination rate decreases. As a mixing method, a known technique such as using a rotary mixer can be employed. When each of the compost and peat moss is classified in advance, the two are mixed substantially uniformly with each other.
[0054]
Next, in the second step S2, the seed mixed compost composition according to the first embodiment is obtained by mixing plant seeds with the compost composition. The amount of seed may be set according to the volume of the seed and the greening area.²It is sufficient to mix at a rate of about 20 g with respect to 20 liters of compost composition for the hit construction. The mixing of seeds in the second step S2 can also be performed by a known technique as described above.
[0055]
The obtained seed mixed compost composition according to the first embodiment is shipped and distributed after being packed in a bag. When germinating from seeds contained in this seed mixed compost composition, moisture may be applied after laying on the soil. Excess water is absorbed by peat moss, so that it is possible to avoid root decay of the plant. Moreover, since the water | moisture content absorbed by peat moss is discharge | released and provided to a plant when temperature is high, it can also avoid that the water | moisture content in a plant body runs short.
[0056]
The seed mixed compost composition (molded product) according to the second embodiment can be produced by molding the seed mixed compost composition according to the first embodiment obtained as described above into a predetermined shape. . That is, the method for producing a seed mixed compost composition according to the second embodiment includes, as shown in FIG. 2, a third step S3 in which starch paste is added after the second step S2, and a seed mixed compost composition. A fourth step S4 for forming by pressurization is added.
[0057]
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 using corn starch with a concentration of 1% by weight, it can be added at a ratio of 10 parts by volume with respect to 100 parts by volume of the mixed seed compost composition. In addition, after adding starch paste, starch paste is disperse | distributed substantially uniformly by stirring a seed mixing compost composition.
[0058]
Next, in a fourth step S4, a seed mixed compost composition in which starch paste is dispersed substantially uniformly is formed. For example, the molding is performed using a mold as follows. That is, the seed mixed compost composition filled in the mold having the bottom is pressed and pressed by a press plate of a pressure press machine to agglomerate the seed mixed compost composition.
[0059]
The pressing pressure at this time is preferably 0.15 to 0.5 MPa. If it is less than 0.15 MPa, the strength of the molded seed mixed compost composition may not be sufficient. Moreover, when it exceeds 0.5 MPa, seeds may be crushed.
[0060]
Then, by drying the starch paste contained in the agglomerated seed mixed compost composition and fixing the compost and peat moss, the seed mixed compost composition according to the second embodiment having a shape corresponding to the shape of the formwork is obtained. It is done. The drying temperature and time are set within a range in which the starch paste can be efficiently dried and cracks and cracks can be avoided in the molded product. For example, when ventilation drying is performed at 40 ° C., a molded article free from cracks and cracks can be obtained reliably by leaving it for about 24 hours.
[0061]
In addition to the above, the seed-mixed compost composition in which seeds that require light for germination are mixed can be manufactured by a manufacturing method whose flowchart is shown in FIG. That is, this manufacturing method includes a first step S10 for obtaining a compost composition, a second step S20 for adding starch paste to the compost composition, and the compost composition to which starch paste has been added as a primary molded product. A third step S30, a fourth step S40 for arranging plant seeds together with soil or compost composition on the surface of the first molded product, and the soil or compost composition and the first molded product. And a fifth step S50 for applying pressure.
[0062]
1st process S10 is performed based on above-described 1st process S1. In short, the compost composition is produced by mixing the compost obtained in the preparation step Ssub1 with peat moss.
[0063]
Next, in the second step S20, starch paste is added to the compost composition in accordance with the third step S3. Here, the compost composition may be mixed with seeds of plants that can germinate without requiring light.
[0064]
After adding starch paste and stirring, in 3rd process S30, a compost | cure composition is pressurized according to said 4th process S4, and it is set as a primary molded article. The upper limit of the press pressure at this time is not particularly limited, but is preferably 0.5 MPa when seeds are mixed in the compost composition. This is because, as described above, there is a concern that the seeds may be crushed when pressure is applied at a press pressure exceeding 0.5 MPa.
[0065]
Next, 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 needs light during germination.
[0066]
And soil is piled up on this seed. Alternatively, the compost composition may be piled up in place of soil. In any case, the thickness is within 0.5 cm so that light reaches the seed. That is, the position of the seed should not be deeper than 0.5 cm.
[0067]
Here, in the fourth step S40, instead of sowing seeds on the primary molded product, soil mixed with seeds in advance may be deposited on the primary molded product. Alternatively, the compost composition in which seeds are mixed in advance, that is, a mixture in which 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 a seed can be 0.5 cm or less from the surface.
[0068]
Finally, in the fifth step S50, the seed mixture according to the second embodiment as a product is obtained by pressurizing the piled soil or compost composition and the primary molded product to form a secondary molded product. A compost composition is obtained. The press pressure at this time is preferably 0.15 to 0.5 MPa in order to avoid the seeds from being crushed.
[0069]
According to the embodiment described above, compost can be effectively used as a greening resource. Therefore, since the consumption of compost increases, the balance between the production and consumption can be achieved. For this reason, the necessity of providing a large-scale storage facility, in other words, the necessity of investing a large amount of equipment installation cost can be eliminated.
[0070]
Moreover, the operation | work at the time of a greening only spreads the said seed mixed compost composition on soil, and it only needs to suppress pressure as needed, Therefore, greening can be performed simply, easily, and rapidly. For this reason, the cost required for greening can be reduced. In addition, what is necessary is just to mount the seed mixed compost composition which concerns on 2nd Embodiment, for example, after cutting out the said area | region and cutting out the area | region, when greening the area | region where the lawn withered.
[0071]
【Example】
Cattle manure or sewage sludge was fermented by aerobic treatment to obtain fully matured compost having a C / N ratio of 24.2 and 20.1. And after adjusting the moisture content of each compost to 15 weight%, it classified using the sieve of 10 mm mesh. On the other hand, peat moss was also classified using a 10 mm mesh sieve, and those passing through the sieve were mixed at various weight ratios to obtain a compost composition.
[0072]
Next, seeds of fescue, bentgrass and bluegrass were stirred and mixed with the obtained compost composition to obtain a seed mixed compost composition, and water was provided to examine the germination rate of the seeds. In addition, about the thing using the compost derived from cow manure, this test was done twice.
[0073]
In addition, for comparison, a control test was performed using a commercially available mixture of grass soil for soil and chemical fertilizer (hereinafter referred to as “control”) and compost. The results are also shown in FIG. From FIG. 4, it is clear that seeds germinate better in the seed mixed compost composition than in the control or compost.
[0074]
Next, the antibacterial activity of the seed mixed compost composition was investigated. Specifically, 10^FourPurified water containing CFU / ml of Psium was inoculated into the mixed seed compost composition and control, and the growth of turf was examined in an artificial weather machine at a temperature of 22 ° C. and a humidity of 60%. As the compost composition, a mixture of compost fermented with cattle manure and peat moss at 50:50 was used.
[0075]
For comparison, an azoxystrobin wettable powder aqueous solution diluted 4000 times was used as an agrochemical at 125 ml / m.²250ml / m²500ml / m²The turf was grown under the above-mentioned conditions by spraying at a rate of 5%, and the relationship between the sprayed amount and the growth status was examined.
[0076]
First, the germination rate after 28 days was 81% in the case of the seed mixed compost composition not inoculated with Psium and no pesticide was used. Regardless of the spraying amount, it was almost the same as about 82 to 85%. On the other hand, in the control, germination rate was 65.3% in the control in which no Pisium bacteria were inoculated and no pesticide was used, whereas 43.0% when the pesticide was not used, the pesticide was used. In case of 125ml / m²44.3%, 250 ml / m²At 57.0%, 500 ml / m²It was 47.3% in both cases, which was lower than when no Psium was inoculated.
[0077]
Next, the incidence of turf after germination is shown in FIG. As can be seen from FIG. 5, in the mixed seed compost composition, the disease incidence is substantially constant regardless of the amount of the agricultural chemical applied, whereas in the control, the disease incidence increases as the amount of the agricultural chemical applied decreases. Showed a tendency to Standard amount (500ml / m²), The morbidity did not fall below the morbidity in the seed-mixed compost composition.
[0078]
From the above results, when the plant is grown using the seed mixed compost composition, it is possible to secure the germination rate without using the pesticide, while suppressing the disease incidence, in other words, the pesticide. It is clear that the usage of can be significantly reduced.
[0079]
【The invention's effect】
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. For this reason, since the production amount and consumption amount of compost can be balanced, the necessity of landfilling organic waste and the need to provide a large-scale storage facility are eliminated. Therefore, it is possible to reduce the load on the environment and avoid an increase in capital investment costs.
[0080]
Moreover, since the peat moss is mixed in the seed mixing compost composition according to the present invention at a predetermined ratio, the concentration of the fertilizer component in the compost is adjusted. Moreover, since peat moss is excellent in water retention, the seeds are not excessively dried. For this reason, the germination rate of a seed becomes favorable.
[0081]
Moreover, the seed-mixed compost composition can be leveled by an easy and simple operation of crushing after spreading on the soil. In the case of a molded article, there is no need to suppress the pressure. That is, since greening can be performed easily in a short period of time, work costs for greening can also be reduced.
[0082]
Furthermore, this seed mixed compost composition has antibacterial activity. For this reason, the germination rate of a plant is favorable and the disease rate is small. Therefore, the use amount of the agricultural chemical can be remarkably reduced, and the effect that the burden on the environment can be further reduced is achieved.
