The pea root system is developed, the absorption capacity is strong, and the soil requirements are not strict, but the neutral and fertile vegetable loose loam or sandy loam is good for the development of root nodules and plant growth; when the soil pH is less than 5.5, the disease is easy to occur and the yield is reduced. . According to research, generally 10 kg of nitrogen, 10 kg of phosphorus (P2O5), and 21 kg of potassium (K2O) are required for every 667 square meters. Fertilization of the base and top dressing and two applications. The base fertilizer is generally applied with 1000-2000 kg of organic fertilizer per 667 square meters, 15-20 kg of superphosphate, and 10-15 kg of potassium chloride. The field management of peas is relatively extensive. In the case of applying the base fertilizer, the nitrogen-fixing ability of the rhizobium is weak in the early stage of plant growth, and 10% of the decomposed human and animal manure can be applied 1-2 times to promote the development of nodule. After flowering and pod-forming, apply 30-40 kg of compound fertilizer per 667 square meters and keep the soil moist.
