Soybean interline mechanical filming technology

Soybean inter-row mechanical film-coating technology is a new agricultural machinery technology that improves ground temperature, drought resistance, moisture conservation, fertilizer control, weed control, quality improvement, production increase and production cost reduction. The new technology of soybean inter-row film mulching adopts the method of “flat-casting film between the lines”, that is, on the basis of autumn land preparation and fertilization in the previous year, the high-quality suitable varieties are selected, the flat land can not be sown, and then six or eight rows are used. The soybean film-coating machine covers the film between the seedling belt and the seedling belt, instead of directly covering the seedling belt, which is easy to operate and practical. The main features of this technology are intra-membrane fertilization and membrane-extended sowing, preventing chemical fertilizers from volatilizing, increasing the utilization rate of chemical fertilizers, and moisture entering the human membrane from the edge of the membrane to prevent evaporation of water, which is conducive to preservation. Using this technology, the soil temperature can be increased by 3-5 ° C, the effective accumulated temperature is increased by about 300 ° C, the fertilizer utilization rate is increased by more than 10%, the soybean yield is increased by about 30%, the protein content is increased by 2 to 3 percentage points, and the fat content is increased by 1.2. Percentage points.

First, the technical points of mechanical filming between lines

1. Good varieties are used. Selection of excellent varieties requires seed purity of over 98% and clarity of 97% I. X~, the germination rate is over 95%, the seed coating rate reaches 100%, and the seed quality is guaranteed.

2. Land preparation. The depth of deep pine reaches more than 25cm, and the land should be flattened and thin, which meets the requirements of sowing and filming to ensure the quality of mechanical work.

3. Sowing and fertilizing. The selection of high-quality hi-water and fertilization original seeds is 55-66kg per hectare, and 120-150kg of diammonium phosphate, 30kg of urea and 50kg of potassium fertilizer are used as base fertilizer per hectare. The seeds are coated with a seed coating and the grass is closed after sowing.

4. Laminating. Adopt 800mm wide mulch film, film thickness is 0.008n1Hl, width after filming is 600~700mm, fertilization position is about 50mm in the edge of film, sowing 50mm from the edge of film, the film should be close to the ground, the film cover is tight, the film joint The place and the hole must be tightly pressed with the earth cover.

5. Control pests and diseases. Through comprehensive technology, the area of ​​soybean gray spot and heartworm disease prevention and control reached 100%. In the aspect of chemical weed control, the pre-emergence soil treatment is the main method, supplemented by post-emergence stem and leaf treatment, and no high-residue chemicals are used to achieve pollution-free and green standards.

6. Field management. In the series of production stages of coated soybeans from planting to harvesting, personnel should be organized for testing records.

7. reward. Single-receipt, single-off, single-storage and single-processing are carried out to ensure the grade of coated soybeans between rows to ensure the purity and quality of the seeds.

Second, the machine used for filming between soybean lines

Soybean inter-line laminating machine mainly adopts 2MFB-4A soybean laminating machine produced by Heilongjiang Nenjiang Agricultural Machinery Co., Ltd., which is composed of two parts: “roof cultivation and ridge film”. The ridge and the four ridges are covered.

Third, the effect analysis

Compared with conventional soybean planting, the mechanized technology of soybean inter-row mulching cultivation is reflected in the “four small, three high, one flat”.

"Four less" includes: 1 less seed input. Due to the improvement of soil moisture, the soybean seedling rate is improved, and the individual development is better, which can reduce the amount of sowing by 25%. 2 weeding costs are small. Soybean mulching cultivation is to stop the grass before planting, and if there is grass shortage outside the membrane, only the normal amount of 40% herbicide can be sprayed with the extra-membrane seedling. 3 mechanical operation costs are small. Soybean film does not need ridges, suppression, and reduces the number of ploughing. 4 less manual investment. After the film is covered, artificial weeding is eliminated, the artificial input is relatively reduced, and the uncovering process is added in time, and 30 yuan per hectare will be invested.

“Three highs” include: 1 high fertilizer utilization rate. As the soybean is coated, the volatilization and leaching loss of the fertilizer are reduced, and the soil moisture is better than that of the bare land, the fertilizer is enhanced in solubility and the utilization rate is high. 2 high quality. After the film is covered, the incidence of the heartworm is reduced, the grain weight is increased, and the commodity is good. 3 high efficiency.
