Summer soybean science fertilization technology

Summer soybeans have always had problems such as neglecting fertilization and extensive management, resulting in low soybean yield. In order to make a breakthrough in the production of soybeans, it is necessary to carry out scientific fertilization according to the characteristics of soybean fertilizer.
1. Adding organic fertilizer Summer soybeans advocate the application of organic fertilizers to the former crops, and fertilize the soil, so that soybeans can use residual fertilizer to increase yield.
2, skillful application of nitrogen fertilizer Because soybean itself has the ability to fix nitrogen, so nitrogen fertilizer does not need to be applied too much, the key is to highlight a "smart" word. Medium-low fertility fields, generally 5-8 kg of urea or 15-20 kg of ammonium bicarbonate; high-fertility fields can be applied with little or no nitrogen fertilizer, and excessive application is not only waste, but also reduces production.
3. Increasing the application of phosphate fertilizer Soybean is a phosphorus-producing crop and requires more phosphorus fertilizer. Therefore, it is necessary to increase the application of phosphate fertilizer in soybean cultivation. Phosphate fertilizer should be applied early, generally 20-25 kg of calcium phosphate per acre.
4. Cooperating with potassium and potassium fertilizers plays an important role in improving crop stress resistance and preventing premature aging of crops. Generally, 10 kg of potassium chloride can be applied per mu, and it is applied to the soil together with the phosphate fertilizer.
5, foliar spray fertilizer after the full bloom period of soybeans, the weak growth, poor growth of the field can be sprayed with 2% urea solution; for the field with symptoms of deficiency, can spray 0.5% of ferrous sulfate solution or 0.2% zinc sulfate solution or 0.05% ammonium molybdate solution.
