A: The use of trace element fertilizers increases or decreases the number of top dressings due to different nutrient-deficient trees. If young trees are used in the later period, they should be sprayed, or sprayed with phosphorus and potassium fertilizers and trace elements 3 to 5 times. The results of the tree from the beginning of the flowering period, until the fall, can be combined outside the root trace trace elements 2 to 5 times. Fertilization method: The soil fertilization has an annular groove, a radial groove and a whole garden. The quick-acting fertilizer is easily absorbed by the soil and can be applied to the soil in shallow amounts. Top dressing should be applied lightly to ensure that fruit trees are needed in the short term. Outside the root dressing: outside the root dressing effect is fast, with fat province. Sometimes combining topdressing with spraying can produce two birds with one stone and save labor. The optimum period of spraying is sprouting and flowering, young fruit period (between 5 and 7 days, spraying nitrogen fertilizer 3 to 5 times, which is beneficial to expanding the leaf area, deepening the leaf color, enhancing photosynthesis and fruit enlargement), and fruit enlargement to harvesting Period (multiple spraying nitrogen and phosphorus fertilizers can enlarge and enhance the fruit, and promote flower bud differentiation to accelerate root growth and tree nutrient accumulation).
