In view of the problems of low organic fertilizer application, no inoculation of rhizobia agents, and neglect of trace element nutrition such as calcium, magnesium, sulfur, boron and molybdenum in soybean fertilization, the following scientific fertilization methods are recommended: reapply organic fertilizer and inoculate soybean rhizobia ; Apply medium and trace element fertilizers to the soil lacking medium and trace elements; 100% organic and phosphate fertilizers and 50% of nitrogen and potassium fertilizers are combined with land preparation as base fertilizer before transplanting, and the fertilizer is raked into the soil after application. Soil and fertilizer integration; 30% nitrogen fertilizer and potassium fertilizer as topdressing fertilizer for seedlings; 20% nitrogen fertilizer and potassium fertilizer as topdressing fertilizer before flowering, first dig a fertilization ditch between two rows of soybeans with a depth of 15-20 cm, Then fertilize and cover the soil.

The specific operation is as follows: the application amount of organic fertilizer is about 2000 kg per mu. Nitrogen, phosphorus and potassium application rate, if the output level per mu is below 150 kg, 8 kg of nitrogen fertilizer per mu, 4 kg of phosphate fertilizer, and 5 kg of potassium fertilizer; for the output level of 150 to 200 kg per mu, 7 kg of nitrogen fertilizer and 3.5 kg of phosphate fertilizer 4.5 kg of potash fertilizer; if the output level per mu is above 200 kg, 6 kg of nitrogen fertilizer, 3 kg of phosphate fertilizer and 4 kg of potassium fertilizer are applied per mu. Before sowing, mix seed with soybean nodule bacteria. Apply 50 to 100 kg of calcium fertilizer per mu. For the soil deficient in boron and molybdenum, 0.1% borax and ammonium molybdate were sprayed at the seedling stage and the initial flowering stage, respectively.
