Talking about the mechanical coating technology between soybeans

Soybean inter-row mechanical coating technology is a new and significant agricultural technology new technology that increases ground temperature, maintains drought resistance, preserves fertilizer, controls weeds, improves quality, increases production, and reduces production costs. The new technology of covering film between soybeans adopts the method of “placing between the rows and the film”, that is, based on the preparation and fertilization of the autumn of the previous year, high-quality suitable varieties, flat land sowing can not be used for ridges, and then six lines or eight lines are used. The soybean film-covering machine covers the mulch 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 the intra-membrane fertilization and film sowing, preventing the volatilization of chemical fertilizers, improving the utilization rate of chemical fertilizers, and the moisture entering the membrane from the edge of the membrane to prevent the evaporation of water, which is beneficial to the protection of earthworms. 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 30%, the protein content is increased by 2-3%, and the fat content is increased by 1.2. Percentage.

First, technical points between mechanical linings

1. Good selection. The selection of fine varieties requires the purity of the seeds to be over 98% and the degree of purity to be 97%. X~, the germination rate reached above 95%, and the seed coating rate reached 100% to ensure seed quality.

2. Land preparation. The depth of deep soil reaches more than 25cm, and the land should be leveled and thin, which meets the requirements for seeding and filming, and ensures the quality of mechanical operations.

3. Sowing and fertilizing. The selection of high quality Xishui Hi fertilizer original species, per hectare sowing amount of 55 ~ 66kg, per hectare application of diammonium phosphate 120 ~ 150kg, urea 30kg, potash 50kg as the base fertilizer. The seeds are coated with a seed coating agent and the herbicide is blocked after sowing.

4. Film. Using 800mm wide plastic film, film thickness of 0.008n1Hl, after coating width of 600 ~ 700mm, fertilization position in the film edge of about 50mm, 50mm from the film edge sowing, mulch film should be close to the ground, the film is covered with tight soil, plastic film joints Department and

Holes must be tightly covered with earth.

5. Prevent pests and weeds. Through comprehensive technologies, the control area of ​​soybean gray spot disease and carnivorous disease has reached 100%. In terms of chemical weeding, we insist on pre-emergence soil treatment, supplemented by post-emergence stem and leaf treatment, and do not use any high-residue chemical agents to achieve pollution-free and green standards.

6. Field management. During a series of production steps from sowing to harvesting, the coated soybeans should be organized to conduct inspections and records.

7. reward. Single-income, single-off, single-storage and single-processing are implemented to ensure that the level of soybeans covered by rows is upgraded to ensure the purity and quality of seeds.

Second, soybeans used between the equipment used

The soybean inter-row laminating machine mainly adopts the 2MFB-4A type soybean laminating machine produced by Nenjiang Agricultural Machinery Co., Ltd. of Heilongjiang Province. The machine is composed of two parts, ie, ridge cultivation and mulching between ridges. It can be broadcast once at a time. Ridges, 4 ridge membranes.

Third, the effect of analysis

Compared with conventional soybean cultivation, the mechanization technology of film-covered cultivation between soybeans is reflected in the “four little, three high, and one flat”.

"Four Less" includes: 1 less seed investment. Due to the improvement of soil moisture, the rate of seedling maintenance of soybeans was increased and the individual development was better, and the sowing rate could be reduced by 25%. 2 Weeding costs are low. Soybean mulching cultivation is to close the treatment before planting. If grass shortage occurs outside the film, only the normal amount of herbicide of 40% can be sprayed with the extra-vegetative seedlings. 3 less mechanical operating costs. Soybean mulching does not require ridging and repression, reducing the number of cultivating. 4 less artificial investment. After the film is covered, the manual weeding is eliminated, the human input is relatively reduced, and the film removal process is added in time, and 30 yuan less will be invested per hectare.

"Three highs" include: (1) High utilization of chemical fertilizers. As the soybeans are coated, the volatilization and leaching loss of fertilizers are reduced, and the soil moisture is better than the bare ground. The solubility of fertilizers is enhanced and the utilization rate is high. 2 high quality. After the film was coated, the incidence of borer disease was reduced, and the weight was increased. The commercial quality was good. 3 high efficiency.
