Strong seedling standards: Different seasons, different times are different due to different seedling temperature, and the seedling time varies. Generally, the seedling age is about 30 days, with 4 to 6 true leaves, the stem is thick and short, no lodging, no disease.
2. Re-application of base fertilizer Before the crop is harvested, it will be deeply turned 20~24cm, and then turned over or frozen. After the shed, 3,000-5000kg of high-quality decomposed organic fertilizer is applied per 667m2, and 30~50kg of superphosphate is mixed, 50~60kg of ash is used, and then 15~18cm is turned deep. Colonization.
3. After the planting, the management of water and fertilizer from the colonization to the principle of bud can not be watered and fertilized, mainly cultivating the soil to promote root development and robust growth of the plant. The third cultivating soil is applied to the base of the first section, so that the base grows the lateral root again and enlarges the absorption area. Immediately after the flower buds, the water is diluted with 500-700kg of dilute or 15~20kg of compound fertilizer, and then the surface is simmered for the last shallow cultivating to control the pods. The first pod is formed into a small pod, and after the second flower is just thanked, it begins to fill the water. In the future, due to the continuous flowering and pod formation of the peas, and the branching at the same time, the amount of fertilizer and water needed to be large, and the fertilizer should be filled once every 10 to 15 days. It is best to use the diluted manure and fertilizer, and apply 10-15 kg of urea each time. 20 to 25 kg of calcium phosphate or 1000 kg of decomposed human urine. In particular, 50 kg of ash or 60 to 20 kg of potassium sulphate per 667 m2 of the pod filling period is used to supplement potassium.
