The water and nutrient absorption ability of the apple tree after water and fertilizer control transformation is largely not affected by the initial stage of growth. However, due to the elimination of a certain amount of branches, the nutrient supply is relatively surplus. Therefore, in order to prevent the trees from prospering and prosperous, they do not encounter particularly arid conditions. Generally, they do not need watering. At the same time, they must strictly control the amount of fertilizers, especially nitrogen, and the strong trees should be dominated by organic fertilizers. In summer, pruning and cutting except for sprouting are the buds of the improper location and useless value when the spring tree just germinated to save nutrients. Afterwards, we will eliminate the useless and harmful new shoots. Picking and cutting tips When the shoots are still lignified, the soft part of the apex (about 4 cm in length) is removed. Its main function is to increase nutrient accumulation and promote branching. When the main branch extends the shoots up to 30-45 cm, it is picked up; when the standing branches reach 25-30 cm, it starts picking up. The cutting tip is a part of the semi-lignification of the shoot, and the part is cut off. The effect is to promote the secondary shoot, and the flower bud is formed in the same year. The girdling and circumcision circumcision and circumcision objects are strong perennial branches, from mid-May to early June, and the girdling width should not exceed 1/10 of the diameter of the shoots. Its role is to promote the formation of flower buds and stripping (cutting) of the branches under the mouth. Twist and shoots are carried out in the middle or late May or early June. When the length of the new shoot is 30cm long and half lignified, the base of the new shoot is twisted by 180 degrees at the base of 2-5cm. Its effect is to inhibit the growth of new shoots. Promote flower bud formation. The branch was taken in June. When the upright vegetative branch grows to 50-60cm in length, the branch is held by hand, and the woody part is gently broken from the base part to the top part until it becomes horizontal or sagging, and its effect is to change. Branching, provoking short branches. Spraying regulators and micro fertilizers to control pests and diseases, adding rare earth and other growth regulators to the liquid, or spraying 300-500 times of amino acid liquid fertilizer and other fertilizers in 6, 7, and 9 months to enhance the photosynthetic capacity of the leaves. Quickly rejuvenate the tree. Promote wound healing, strict erosion preservatives. After the transformation of the tree, many large wounds are caused to the tree body. Apply various types of agents to promote wound healing in time and wrap them with plastic film.
