Apple trees should be treated differently for each age group.
1. What are the fertilization characteristics of Wangshu and weak trees? 1. The fertilization characteristics of Wangshu are: (1) Adopting early fertilization, promoting spring shoots and controlling autumn shoots. Or fertilize the autumn shoots, or apply the base fertilizer early, and combine the deep roots. (2) In the amount of fertilizer applied, it should be applied less or temporarily. (3) On the fertilization varieties, phosphorus and potassium fertilizers are mainly used to control nitrogen fertilizer. (4) On the fertilization method, deep application of base fertilizer is carried out to strengthen the top dressing. 2. The characteristics of weak tree fertilization are: Contrary to Wangshu, more organic fertilizer should be applied, more nitrogen fertilizer should be applied, and ground top dressing and root top dressing should be used to strengthen vegetative growth and restore tree potential. 2. What is the difference between tree fertilization at different ages? 1. Young Wangshu trees have less flowers, and they need to control nitrogen fertilizers and apply more phosphorus and potassium fertilizers. The position and depth of fertilization should be expanded and deepened year by year. 2. The growth from the initial fruit to the fruiting stage is gradually slowed down, and the amount of fruit is gradually increasing. On the basis of phosphorus and potassium fertilizers, nitrogen fertilizer is appropriately increased, deepening is turned over, and the tree nest is placed. 3. Fruiting and aging results and growth balance or excessive results. It is necessary to focus on promoting the early growth. The base fertilizer should be applied early, applied more, and applied deeper; the soil topdressing should be carried out more times and in sufficient quantity, and the number of spraying fertilizers should be increased; the proportion of nitrogen fertilizer should be gradually increased, and the irrigation should be combined to promote strong trees and high yield.
