Problems solved by technology

[0002] Soybean is an important grain and oil crop in my country. The traditional soybean planting process in saline-alkaline areas mainly uses fertilizers composed of three inorganic elements: nitrogen, phosphorus and potassium. Although it can meet the growth needs of soybeans, long-term use will cause soil "salt, Alkali, board, and thin" will be more serious, the soil production capacity will decline, and the yield and quality of soybeans will decline.
In addition, farmers' planting level is not high, regardless of nutrient quantity, form and physiological effects, blind and empirical fertilization methods further restrict crop growth and nutrient absorption, resulting in low yield and low fertilizer utilization rate, which will also increase The risk of environmental pollution and low income also affect the enthusiasm of farmers to plant soybeans, which is a difficult problem for the promotion and planting of soybeans

Embodiment 1

[0042] The soil salt content is 0.29%. Within one week before soybean planting, spread base fertilizer (100kg / mu organic fertilizer (cow dung treated with earthworms)+100kg / mu biochar (straw)+80kg / mu humic acid soil conditioner ( Humic acid + furfural slag + aluminum sulfate + phosphogypsum)) and then cultivated land, mixed into the plow layer soil.

[0043] When planting soybeans, use a soybean seed fertilizer simulcasting machine, apply 2.7kg of urea, 36kg of superphosphate, and 8kg of potassium sulfate per mu of land at 6cm from the seed side, with a depth of 10cm.

[0044] At the soybean branching stage, spray 100g of borax, 20g of ammonium molybdate, and 50g of zinc sulfate per mu, (that is, the mass ratio of borax, ammonium molybdate and zinc sulfate is 100:20:50, and the mass concentration of borax is 0.33%, the mass concentration of ammonium molybdate is 0.07%, and the mass concentration of zinc sulfate is 0.17%).

Embodiment 2

[0048] The salt content of the soil is 0.45%. Within one week before soybean planting, spread base fertilizer (160kg / mu organic fertilizer (cow dung treated with earthworms)+120kg / mu biochar (straw)+100kg / mu humic acid soil conditioner ( Humic acid + furfural slag + aluminum sulfate + phosphogypsum)) and then cultivated land, mixed into the plow layer soil.

[0049] When planting soybeans, use a soybean seed fertilizer simulcasting machine to apply 6kg of ammonium polyphosphate and 6kg of potassium sulfate per mu, at 6cm from the seed side, at a depth of 10cm.

[0050] At the soybean branching stage, spray 87g of foliar fertilizer borax, 30g of ammonium molybdate, and 60g of zinc sulfate per mu (that is, the mass ratio of borax, ammonium molybdate and zinc sulfate is 87:30:60, and the mass concentration of borax is 0.29 %, the mass concentration of ammonium molybdate is 0.1%, and the mass concentration of zinc sulfate is 0.2%).
