Common vegetable fertilization method

In view of the low application rate of organic fertilizers applied to melon, eggplant, fruit and legumes, the application of nitrogen fertilizers in partial or excessive application, and the neglect of potassium fertilizer application, etc., insisting on the combination of organic fertilizers and nitrogen, phosphorus and potassium. Application, the application of potassium fertilizer in the middle and late stages has an important role in reducing deformed fruit and improving fruit quality.

Application of organic fertilizer: about 3000 pieces per mu.

Application of NPK: The output level per mu is below 2000 kg, 13 kg of nitrogen fertilizer, 7 kg of phosphate fertilizer and 10 kg of potassium fertilizer; the yield level per mu is 2000-2500 kg, 12 kg of nitrogen fertilizer is applied, and 6.5 kg of phosphate fertilizer is applied. Potassium fertilizer 9.5 kg; the output level per mu is more than 2500 kg, 11 kg of nitrogen fertilizer, 6 kg of phosphate fertilizer and 9 kg of potash fertilizer.

Fertilization method: base fertilizer, generally apply high-quality soil fertilizer or pig and cow dung 3000 kg per mu before transplanting, and use 100% phosphate fertilizer and 20% nitrogen and potassium fertilizer as base fertilizer. The amount of seedling fertilizer is generally 10% of the total amount of nitrogen and potassium fertilizer applied. During the development of the ear, the amount of fertilizer applied is generally 70% of the total amount of nitrogen and potassium fertilizer applied. During this period, the fertilizer should be applied in several stages, and the fertilizer should be applied once every 10 days. In the middle and late stages, the 0.2% potassium dihydrogen phosphate solution was sprayed 2 to 3 times on the foliar surface, which had a good effect.
