Before flowering and fruit setting, the topdressing type is mainly nitrogen and phosphorus, in order to promote plant vegetative growth and flower bud differentiation; phosphorus and potassium fertilizer are dominant in flowering and fruiting stage; in the middle and late stages of vegetable growth, attention is paid to the comprehensive supplement of NPK, and it can also be based on actual conditions. Fertilization on the surface prevents premature aging of plants, promotes nutrient reflux, and increases yield. The general amount of topdressing is 15-20 kg. Promote rooting, optional amino acid type, humic acid marine biotype, microbial fertilizer, according to product characteristics and requirements, the dosage is generally about 20-25 kg per mu.
