Problems solved by technology

[0004] However, due to the traditional planting method of planting in rows and columns along the length of the border field, the land utilization rate is low, and the gap between soybean plants is small after they are mature, which is not conducive to ventilation and light transmission, and affects soybean yield.

Embodiment 1

[0031] A cultivation method for improving soybean yield potential, comprising the steps of:

[0032] S1. Seed selection, select soybean varieties with lodging resistance, high yield potential, dwarf stalk, semi-dwarf stalk, convergent plant type, high quality, high yield, high protein, and high oil;

[0033] S2. Seed treatment, screening high-quality seeds, coating the screened seeds, using soybean seed coating agent for coating treatment, fully mixing and stirring the soybean seed coating agent and soybean seeds according to the ratio of drug to seed ratio of 1:260;

[0034] S3. Farmland treatment, for subsoiling of farmland, the depth of loosening shall not be less than 35cm. During the subsoiling process, the soil shall be refined so that the radius of the soil block is less than 2cm. After that, ridges shall be formed with a width of 32cm and a height of 35cm, and drip irrigation shall be laid between the ridges. Deep fertilization at the same time as the ridges, the ferti...

Embodiment 2

[0043] like Figure 1-5As shown, the alternate seeder includes a material box 1, the bottom of the material box 1 is fixedly connected to two crossbars 5, and each of the crossbars 5 is rotatably connected to a group of shoe-type seeding heads 2, two groups of The shoe-type sowing head 2 is fixedly connected with the material box 1 through a locking adjustment mechanism, and each group of the shoe-type sowing heads 2 includes several sowing plowshares fixedly connected with the connecting rod 21, and the top of each sowing plowshare is passed through a soft The pipe communicates with the material box 1, the connecting rod 21 is rotationally connected with the cross bar 5 through the suspension rod 3, and the adjustment locking mechanism includes a threaded cylinder 4 threadedly connected with the cross bar 5, and the threaded cylinder 4 is connected with the cross bar 5 through the insertion rod 42. The insertion sleeve 64 connected to the side of the liquid cylinder 6 is plug...

Abstract

The invention provides a cultivation method for improving the soybean yield potential, and relates to the field of soybean cultivation. A narrow-row close planting technology is adopted as a seeding manner, two rows of soybeans are planted on a 32 cm ridge, the soybeans are alternately planted, the distance between adjacent seed holes of the soybeans is about 17 cm, soybean seedlings have enough growth space, soybean seedling leaf overlapping is avoided in an alternate seeding manner, light and air can enter the bottoms of the seedlings, the light transmission and ventilation are high, and theyield is obviously increased; an alternate sowing machine sowing manner is adopted, the seed holes can be evenly distributed in an alternate manner through two sets of boot-type sowing heads front and back, and the distance between the seed holes is guaranteed; and two sets of boot-type seeding plowshares are connected through a locking adjusting mechanism, so that the front-back distance and theleft-right distance between the two sets of seeding plowshares can be changed and can be adjusted according to seeding requirements. Compared with a special seeder, the adaptability is high.

Description

technical field [0001] The invention relates to the field of soybean cultivation, in particular to a cultivation method for improving soybean yield potential. Background technique [0002] At present, the soybean production method stays in the traditional cultivation method, the planting density is low, the field utilization rate is low, the yield is obviously low, the yield of harvested fruit is low, and the economic benefit is low, resulting in waste of land resources. The reason why soybean production in developed countries is much higher than the world average level is that one of the most important factors is that these countries have generally used close planting methods. From the perspective of soybean production in developed countries, soybean production is a medium-input, medium-output industry. In the past ten years, a major innovation in foreign soybean production is the popularization and application of genetically modified soybeans. Since the approval of glyph...
