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.

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%).

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a saline-alkali soil soybean fertilizer and a fertilizing method for improving saline-alkali soil soybean nutrient efficiency. The invention provides a soybean fertilizer for saline-alkali soil. The soybean fertilizer comprises a base fertilizer, a seed fertilizer, a topdressing, a nitrification inhibitor anda foliar fertilizer which are independently packaged, wherein the base fertilizer comprises an organic fertilizer, a soil conditioner and charcoal. The fertilizer combination provided by the inventioncan improve the fertilizer utilization rate and achieve the technical effect of improving the crop yield; and the fertilizer composition provided by the invention can improve the physical and chemical properties of soil, improve the productivity of soil and reduce environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a saline-alkali soil soybean fertilizer and a fertilization method for improving the nutrient efficiency of saline-alkali soil soybeans. Background technique [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, The degree of alkali, board, and thinness will be more serious, the soil production capacity will decrease, 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 lo...
