Description

A kind of planting method for green control and efficient production of chicory for northern flour

technical field

The invention belongs to the technical field of plant planting, and in particular relates to a planting method for the green control and efficient production of chicory for northern flour.

Background technique

Chicory is a herbaceous plant of the genus Asteraceae, native to Europe. Introduced to China in the 1980s, it has the potential for development in many aspects such as food and medicine. The unique elements contained in chicory have the effect of clearing the liver and gallbladder, preventing disease and fighting cancer. Inulin extracted from chicory root can improve the activity of digestive organs, and has certain curative effects on hypertension and diabetes. Its tender shoots can be used as a unique raw vegetable, fresh and slightly bitter, clearing the heart and removing fire. At present, chicory has become the most promising economic crop. Chicory is a dicotyledonous plant, its root is long and stout, shaped like a radish, and a single root can grow to about 2 kg. The stem is erect, the leaves are alternate, the leaves are long oblanceolate, the apex is acute, the leaf margin is toothed, the average height of the leaf stage is about 40-50 cm, there are 25-42 leaves, the leaves are 30-40 cm long, and the leaves are 8 cm wide. -12 cm.

At present, the following problems exist in the cultivation of chicory for flour in the north:

1. The planting method is outdated. Most of the growers still use the traditional flat land planting. The rainy season in the north is concentrated, and there are often large-scale waterlogging caused by plant death, high incidence of diseases and insect pests, or no harvest.

2. The planting technology is backward, and most people are still using chemical fertilizers, pesticides and growth regulators (expanding agents), which can easily cause the powdered chicory residues and plant hormones to exceed the standard, and the inulin content in the powdered chicory will be unstable. This makes the economy of growers not high.

3. The most important thing about chicory for powder is that the root diseases are frequent and serious, such as root rot, scab, soft rot and black heart, etc., which have a great impact on root tuber yield and inulin content. How to use ecological plant protection technology to control pests and diseases is particularly important.

In view of the above reasons, the present invention is proposed.

SUMMARY OF THE INVENTION

In order to solve the above problems existing in the prior art, the present invention provides a planting method for the green control and efficient production of chicory for northern flour. The method of spraying microbial inoculants at regular intervals has the advantages of low root rot, high yield and low cost.

In order to achieve the above object, the present invention adopts the following technical solutions:

A planting method for the green control and efficient production of chicory for northern powder, comprising the following steps:

(1) Selection of land and stubble, deep ploughing and soil preparation, and application of base fertilizer;

(2) soil-dressing planting is carried out with chicory seed and microbial inoculum, and described planting adopts direct seeding, mechanical direct seeding or seedling transplanting;

(3) Field management: watering, cultivating weeding, disease control, harvesting.

Choose loam or sandy loam with watering conditions, flat terrain, fertile soil, loose structure, deep soil layer and good drainage as the cultivation plot. It is best to choose a previous crop with shallow roots, but be sure to choose a plot with no herbicide residues for planting chicory.

Further, in step (1), the depth of deep ploughing is greater than 35cm.

Chicory is a deep-rooted crop, and the rhizome grows to a depth of more than 30 cm. During the growth process of chicory, it needs to absorb a lot of nutrients and water. Therefore, it is required to dig the ground to a depth of 35 cm, leveling and raking, and ridge planting.

Further, according to parts by weight, the base fertilizer is a mixture of 2800-3200 parts of farmyard manure per mu and 35-45 parts of compound fertilizer.

Further, the ratio of nitrogen, phosphorus and potassium in the compound fertilizer is 12:18:15 or 12:19:16.

When the diameter of the chicory root is 0.5 cm, 8 kg of urea per mu is topdressed according to the plant growth and leaf color, and 10-20 kg of compound fertilizer is topdressed when the leaves are 25 and the chicory root is about 2 cm. Topdressing should also be applied 10-15 cm deep, 8 cm away from the rhizome. Otherwise, the fertilization is shallow and the fertilizer utilization rate is reduced.

Further, the microbial inoculum described in the step (2) is a mixture of the spores of Mycoplasma pink and Bacillus thuringiensis.

Further, the number of viable bacteria of the described pink Scopularia spores is 9-1.1 billion/g, and 1.8-2.2kg is applied per mu, and the number of viable bacteria of the described Bacillus thuringiensis is 9.5-10.5 billion/g, and each 100-150g per mu.

Further, when direct seeding is adopted in step (2), the temperature of the soil at a depth of 10 cm is required to be greater than 7°C, and the sowing time is mid-to-early May.

Further, the planting plots were ridged according to 45cm row spacing, and 15cm plant spacing was planted on the ridge platform, the sowing depth was 0.5-1cm, and 8500-9500 seeds were planted per mu.

A series of data show that cultivation on high borders is not only conducive to the growth of powdered chicory, avoiding waterlogging and rotten roots caused by the concentrated rainy season in the north, but also conducive to the management and harvesting of powdered chicory, the growth of tuberous roots and the accumulation of active ingredients.

Further, after sowing, water until the soil moisture content is 65-75%.

Seeds need sufficient water for germination and germination. Generally, when the soil water content reaches 65-75%, it is suitable for chicory seeds to germinate and germinate. Therefore, water in time after sowing, and always ensure that the soil is moist to ensure that the seeds germinate and emerge.

The sowing period of chicory, like other crops, has obvious seasonality. Sowing too early and weak seedlings have a great impact on the yield and quality of chicory per unit area. If sowing is too late, chicory emerges quickly, but the number of growing days is not enough, and the yield and quality per unit area are not good.

Live seeding: suitable for small-scale planting by farmers;

Mechanical sowing: suitable for large-scale planting;

Seedling transplanting: suitable for areas with heavy wind and sand in spring.

Further, when using mechanical live broadcasting in step (2), the sowing depth is 0.8-1.2 cm, the row spacing is 43-47 cm, and the plant spacing is 13-17 cm.

Further, when the seedlings are raised and transplanted in step (2), when the seedling age reaches 23-27 days, 3-4 true leaves are transplanted, and the number of plants per mu is 6500-7500.

The advantages of seedling transplanting are as follows: In some areas, the seedling preservation rate is low due to natural factors such as wind and sand, drought, and frost damage during the spring sowing period, so direct seeding is not suitable. Using the seedling transplanting technology, the seedling stage is changed to the seedbed cultivation, and the large-scale seedling stage seedling protection work is concentrated on a small area, so the seedling conservation rate can be improved, and the yield per mu can be increased accordingly.

The specific method of seedling transplanting is as follows:

①Nursing paper tube: 1400 single tubes per volume. When unfolded, the booklet is 116 cm long, 29 cm wide and 15 cm high. The single cylinder is a regular hexagon with a diameter of 1.9 cm. Use 5 paper tubes per acre.

② Seedling time: when the average daily temperature reaches zero degrees Celsius, the shed and sowing will begin. The dam is generally planted in the shed from April 1st to April 15th, and the dam on the shed from April 15th to April 25th. It is best to start seedlings early in the cold tail and warm head weather. Seedling preparations should be done early. It is best to retrieve the seedling soil in the fall of the first year.

③ Nursery site: choose a plot that is sunny and sheltered from wind, flat, well-drained, easy to manage, and easy to transport. Before raising seedlings, remove snow and debris, and level the ground when the surface is thawed to 10 cm to make the ground level and consistent.

④ Type of seedling shed: First, the small arch shed for planting in a small area: the height of the shed is 80 cm. 2 meters wide, with 80 cm spacing between the scaffolding. There is a row of seedbeds in the shed. Then use a small arch of a wicker frame to cover the shed film on the seedbed. The second is the large arched shed for large-scale planting: the height of the shed is 1.5 meters, the width is 4 meters, and the interval between the scaffolds is 1 meter. There are two rows of seedbeds in the shed, and a simple door is made at the southern end for easy management.

⑤ Preparation of bed soil: The bed soil is fertile and free from herbicides and the surface loose soil is used. It can be formed into a ball by hand, and can be dispersed after landing. When raising seedlings, the soil is sieved with a sieve of 0.6-0.8 cm, and the seedling fertilizer is added and repeated. Mix well.

⑥ Loading soil: Open the paper booklet on the seedbed, pour dry soil into the paper tube and tap it lightly with a wooden board. The paper tube is filled with seedling soil. Put straight, level, flat, the bed surface is in a horizontal state.

⑦Put the soil ridge: The arranged paper tubes in the shed are surrounded by soil ridges. The soil ridge is a trapezoid with a width of 15 cm at the top and a width of 30 cm at the bottom. After the soil ridge is cultivated, the soil ridge is photographed.

⑧ Watering the shed: Pour the seedling bed with water. After watering, the soil in the paper tube will sink, and then put the seedling soil into the seedling hole of 0.5 cm, and then cover the scaffold with a shed film to increase the temperature for 1-2 days.

⑨Sowing: The sowing depth is within 0.5 cm, 1 seed is sown in each single tube, and the soil is covered after sowing. After covering the soil and watering, the shed is immediately closed. There are 1-2 thermometers in the shed, and the low end of the thermometer is 10 cm away from the bed surface.

Seedling shed management: The central task of the seedling shed management stage is to cultivate strong seedlings. The standard is: dark green and glossy leaves, thick and firm leaves, neat and consistent seedlings, not long and thin, no disease, fast rooting after transplanting, and fast slow seedlings.

①Temperature adjustment: If the temperature is low, the emergence of seedlings will be slow, the size of seedlings will vary, and the seedlings will not be strong. If the temperature is too high, the seedlings will grow quickly in the early stage, and the seedlings will be thin and weak. Temperature control in the shed: keep the temperature at 20 degrees during the day, not more than 25 degrees, and 10 degrees at night, not lower than 5 degrees. When the temperature in the shed is higher than the requirement, it is necessary to ventilate and cool down. According to the principle of ventilation, first small and then large, first short and then long, the ventilation position is often changed. 20 days after the emergence of the seedlings, it should be domesticated to make it gradually approach the temperature outside the shed to prevent the seedlings from growing too long. The shed film can be removed during the day, and the film should be well covered in case of frost or rain.

②Moisture control: Under the condition that the shed is watered with sufficient water, the bed surface should always be kept moist before emergence, and sprayed when it is dry. After emergence, it should be properly sprayed according to the water demand of the seedlings. If the bed surface is too wet, it is easy to get blight after emergence. . If the bed surface is too dry, the sprouts are easy to dry before emergence, and the seedlings are easy to be roasted to death after emergence.

Transplanting technology

①. Transplanting time: The seedlings are about 25 days old and can be transplanted when there are 3-4 true leaves.

②, from seedlings: the day before transplanting, water the seedbed thoroughly, as much as you plant. When raising the seedlings, insert a flat shovel into the bottom of the paper booklet to gently rise, or lift it up by hand, put it in the seedling box, and arrange it closely.

Transplanting method:

①Artificial transplanting: Use a steel pipe or a round wooden stick with a diameter larger than the paper tube, sharpen the head to a point, and tie a 16 cm seedling eye on the ridge bed, and plant the seedling after the eye is dazzled.

②Transplanting by transplanter: Use a seedling transplanter to transplant.

(6) Transplanting density: According to soil fertility, the fertilization level is reasonable and densely planted, generally about 6500-7500 plants per mu.

(7), transplanting quality:

① Plant in the right direction, plant in the center of the ridge, to prevent planting sideways.

② Plant straight, do not nest roots, prevent bending and pinching off half of the roots, otherwise the growth of chicory will be seriously affected, and the seedlings will be easily damaged during cultivating, and it is also easy to die from drought.

③ Plant evenly and the depth is suitable. The upper end of the paper tube is level with the ridge and cannot be exposed or buried.

④ The soil should be cultivated strictly according to the actual situation to prevent running away moisture.

⑤ The size of the seedlings are planted separately. Injured root seedlings, broken seedlings, broken tube seedlings, broken tube seedlings, and tube soil shedding seedlings cannot be planted.

⑥It must be watered after transplanting.

⑦ Stop transplanting in case of low temperature and frost when transplanting.

⑧ Check the field and replant: check the field and make up the seedling in time after slowing down the seedlings. Make up for dead seedlings, diseased and weak seedlings, and missed plantings, and re-cultivate those exposed on the ground strictly.

Further, in step (3), cultivating and weeding is to lay 4-6 cm of fermented broken straw or fermented waste fungus material on the whole border when the height of sowing or transplanted seedlings is 10 cm.

Further, the length of the straw is less than 3cm, and the waste fungus material is grass-rot fungus or wood-rot fungus.

The use of fully decomposed organic wastes such as straw, waste fungus and other organic wastes has the following advantages: First, the use of fully decomposed organic matter covering will not increase the sources of diseases and insect pests in the powdered chicory field, on the contrary, it will also reduce the occurrence of some diseases and insect pests. It has inhibitory effect; second, it has a good biological "weed control" function. After the first complete weeding in the first year, it can be covered, so that most grass species can be cured, and a small number of grass species are used in the daily management and maintenance of powdered chicory. It can be removed, which greatly reduces labor, and has the advantages of no chemical pollution and one-time multi-use compared to films. Third, it has the effect of dehumidification and moisture absorption, which can greatly avoid rainwater washing powder in the rainy season. Plant damage and soil bacteria splashing with chicory Fourth, it has a good thermal insulation effect, laying biological organic matter can better form a thermal insulation layer on the soil surface, and increase the accumulation of nutrients and effective components in the roots; fifth, increase soil organic matter, which has a similar effect Different from organic fertilizers, organic fertilizers are covered with biomass, and the organic matter of biomass will be precipitated and gradually infiltrated into the soil layer in the open environment through "wind, sun and rain", increasing the content of various trace elements in the soil, thereby improving The quality and yield of chicory used for powder; Sixth, the use of microbial inoculants can provide a good place and food for the reproduction of beneficial microorganisms (spores of Mycoplasma pink).

Further, disease control is in early June, applying 1.8-2.2kg of pink spores of spores of spores of spores of 9-11 billion/g per mu, and applying 2-3 spores of spores every year. Second-rate.

If the leaves of the powdered chicory are seriously diseased, the Trichoderma thick spore preparation can be sprayed in the rosette stage, which can effectively control the wilt and yellowing caused by pathogenic bacteria such as Fusarium, Pythium, Rhizoctonia solani, Verticillium, and Phytophthora. wilt and other diseases, the preparation has strong tolerance to adverse environment, long lasting effect and stable control effect.

In the later stage, if insect pests such as Homoptera, Coleoptera, and Lepidoptera occur, biological agents such as cereus, Bt, Beauveria bassiana, and Metarhizium anisoplia should be sprayed for green prevention and control.

The field management of chicory is to create a good environment for the growth and development of chicory in terms of water, heat, air, light and nutrient supply under the management of cultivating, weeding, top dressing, and watering.

In spring, the wind is strong and the rain is low. After sowing, water should be timely to keep the soil moist to ensure the normal germination and emergence of chicory seeds, but the amount of water should not be too large, otherwise the soil humidity in spring will be high, the ground temperature will be low, and the roots will not be deeply rooted, which will affect the growth of chicory. During the growth period of chicory, the number of leaves gradually increases and the leaf area expands. It is necessary to ensure the timely supply of water, keep the soil wet and dry, and stop watering 15 days before harvest.

Cultivation is to loosen the soil, eliminate weeds, improve soil permeability and nutritional status, increase the ground temperature and the ability to accept water, thereby promoting root growth. During the growth period of chicory, deep sowing of the furrows must be carried out, and the grass must be pulled out before the ridges are closed.

Disease control: Chicory is a crop with strong disease resistance, and diseases rarely occur, but it is easy to rot when the soil water content is too large, so once the plot of chicory has accumulated water, it should be drained in time to prevent vegetable roots from rotting.

Harvest of chicory: During the growth period of chicory, the leaves cannot be cut, and the secluded leaves will destroy its functional leaves, which will affect the expansion and growth of its fleshy roots. Harvest in time to prevent the phenomenon of frozen vegetables and frozen vegetables into the ground. The Bashang area began to harvest after October 5th, and the Basha area began to harvest on October 10th. There are two methods of harvesting: mechanical harvesting and manual harvesting. Mechanical harvesting is to use a machine to kill the seedlings and then use a large harvester to directly receive them on a truck and transport them to the factory; manual harvesting uses a rotary plow to manually cut off the leaves from the base of the stem and load it on a truck. to the factory.

Youpin is a high-quality chicory with high dry matter content, uniform growth, less branching, and no disease and mechanical damage. Do not bring rotten leaves and clods and rocks when harvesting.
