The pea roots are well-developed, have strong absorptive capacity, and do not require strict soil requirements. However, neutral and fertile ground pine or sandy loam soils are preferred to facilitate root nodule development and plant growth; soil pH values ​​less than 5.5 are susceptible to disease and reduce yield. . According to the research, it is generally necessary to apply 10kg of nitrogen, 10kg of phosphorus (P2O5), and 21kg of potassium (K2O) per 667m2. Fertilization bases and topdressing and two applications. Basal fertilizer generally applies 1,000 to 2000 kg of organic fertilizer per 667 square meters, 15 to 20 kg of superphosphate, and 10 to 15 kg of potassium chloride. Field management of peas is extensive. In the case of basal fertilization, in the initial stage of plant growth, the ability of nitrogen fixation of Rhizobium is weak, and 10% of human and animal manure water can be applied to promote root nodule development. After flowering, 30,40 kg of compound fertilizer is applied per 667 square meters, and the soil is kept moist.
