After the peach tree results, it consumes a lot of nutrients, and the peach harvest coincides with the rainy season. If the technical management can be strengthened in time, the nutrient accumulation of the tree body can be increased, the tree potential can be restored as soon as possible, and a good flower bud can be formed to improve the next year. Peach yield and quality create favorable material conditions.
Underground fertilizer management. Through the management of underground fertilizer and water, the tree body can be quickly absorbed and supplemented with nutrients. After the peach harvesting, the quick-acting fertilizer is applied in time. The initial fruiting period is 0.25 kg of urea per plant and 0.5 kg of urea per plant. It is necessary to control the application rate of nitrogen fertilizer to prevent the branches from growing and affecting flower bud differentiation. Foliar spray application is carried out in combination with pest control. From August to September, 0.3% to 0.5% potassium dihydrogen phosphate solution is used, with an interval of 15 days. From September to October, combined with deep-expanding and expanding, the base fertilizer is mainly used, and the fully-fertilized farm organic fertilizer is mainly used, supplemented by ternary compound fertilizer. At the beginning of the fruit period, 50-100 kg of organic fertilizer is applied to each plant, and 0.5-1 kg of ternary compound fertilizer is applied. The mature manure is applied with 100-200 kg of organic fertilizer and 1-2 kg of ternary compound fertilizer. The fertilization method can be either an annular groove or a radial groove, and the application depth is 30 to 50 cm.
After the peach harvest, there is more rainwater, so it is not necessary to water. If the drought time is too long, it can be watered and supplemented as appropriate. In the rainy season, it should be drained and flood-proof, cultivating and weeding to prevent soil compaction, and the frozen water should be sealed once before the soil is frozen.
