Open big branch angle. The method of drawing, bracing, pressing, connecting, sawing, etc. can be used to achieve the standard angle of the main, lateral and auxiliary branches, which is beneficial to improving the light conditions, alleviating the branching tendency, promoting the middle and short branches, and easily forming flowers.
Delay trimming. It is to postpone the winter shear until the bud grows to 5 cm. The method is basically the same as winter shear. But there are two things to note: First, this method can only be carried out on Wangshu and Wangzhi. Second, usually after 2 years of delayed pruning, Wangshu and Wangzhi can generally be eased and stabilized. In the third year, they must be transferred. Into the normal winter trim, otherwise it will weaken the tree potential and branching.
Excision surgery. Engraving is divided into four types: scratch, girdling, ring cutting, and peeling. Injuries are cut with scissors immediately above and below the branches and buds; girdling is stripping a bark of a certain width; circumcision is using a knife edge to circumnavigate the twigs and stems for a week; The bark of the bark is turned upside down and attached to the ring.
Try to lightly cut long. Practice has shown that apple trees do not grow fast, they increase quickly, they have large shoots and shoots, they have large crowns, and the results are early. Only with light shear, there is a larger amount of shoots and buds, which is good for premature birth and early-blooming; middle shearing and heavy shearing, Large amounts of cuts, small amounts of shoots and buds, and weakening, result in less late.
Branch culture methods. If the apple tree branches are not cultivated at the appropriate age, they can be lightly weighted first (also known as the first shrinking method), and the effect is better. In addition, we should pay attention to the appropriate number of flowers and fruits, in order to promote the conversion of plants to normal results, the better.
Sparsely cut branches. Timely sparse development of dense branches, prosperous upright branches, inward branches, thin branches, leggy branches and competition branches, etc., will help improve light conditions, increase nutrient accumulation, reduce nutrient consumption, and promote flower bud formation.
Press the tree to reduce the trend. For tree heads that are strong, weak, strong, and overly tall, it is best to bend the trees in a space on the north side of the canopy. The angle of the branches is 90 degrees to fix them; Leading the curved extension.
Apple trees do not produce results
Appropriate control of fertilizer and water. The appropriate age is not the result of the tree, and the growth of the tree is generally excessive. Therefore, in the supply of fertilizer and water, we should grasp the principle of early promotion and post-control, and avoid the prosperous growth in the early stage and the non-stop growth in the later stage.
