According to the principle of “one control, two promotion, three guarantees, and four bogeyâ€, fertilization is applied several times. One control is to control fertilization during flowering period, so as to avoid falling flowers, deciduous leaves and fruit drop; second promotion is to timely topdress the young fruit period and harvest period. Promote the rapid expansion of young fruit; the three guarantees are not to lose fertilizer, not long, not fat; four bogey is to avoid using high-concentration fertilizer, avoid wet soil topdressing, avoid high temperature when topdressing and avoid too concentrated topdressing.
Application of organic fertilizer: about 3000 kg per mu.
Application of NPK: The output level per mu is more than 2500 kg, 10 kg of nitrogen fertilizer, 7 kg of phosphate fertilizer and 10 kg of potassium fertilizer; the yield level per mu is 2000-2500 kg, 9 kg of nitrogen fertilizer is applied, and 6.5 mm of phosphate fertilizer Potassium fertilizer 9 kg; the output level per mu is below 2000 kg, 8 kg of nitrogen fertilizer, 6 kg of phosphate fertilizer and 8 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 30% nitrogen and potassium fertilizer as base fertilizer. The application rate of seedling fertilizer is generally 50% of the total amount of nitrogen and potassium fertilizer applied. During this period, the top dressing should be applied separately, and the topdressing should be applied once every 10 days to promote stem and leaf growth. The fertilizer is applied in an amount of 30% of the total amount of nitrogen and potassium fertilizers, which promotes tuber swelling and increases yield. Melons, eggplants, fruits, and beans are sprayed with 0.2% potassium dihydrogen phosphate solution 2 to 3 times in the middle and late growth stages, which has good effects.
