Apple Orchard Management Essentials in Spring

Apple Orchard Management Essentials in Spring

The one-year plan is spring. The management of orchards in spring is very important, and pre-emergence management is a top priority. In the budding stage to take certain technical means, for the adjustment of the growth of shoots, light improvement, germination and transformation of buds can play four or two pounds. At the same time, before the sprouting in spring, it is a critical period for the control of various pests and diseases. Qingyuan has done a good job with fewer pests and diseases throughout the year. In addition, the sprouting, flowering, fruit setting, spring shoots, and cold resistance of fruit trees are closely related to tree nutrient and tree vigor. Therefore, we must pay attention to fertilizer and water management in the spring.

Carved buds, branches open angle

There are three major tasks in shaping fruit tree pruning, adjusting lighting, adjusting tree vigor, and adjusting load. A reasonable distribution of trees and branches is a prerequisite for ensuring good lighting. However, it is not enough to just do these tasks. It is also necessary to adjust the tree potential, twig forces, and load of fruit trees. The pre-emergence period is a crucial period for the adjustment of twig forces and loads.

This period mainly to do good Wangzhi carved buds, virtual Wang branches divided cut, small virtual Wang branches (especially on the back) to promote Meng (15 cm), the longer can be divided by 4 to 5 buds. The branches that are particularly prosperous can also be used to help restrain the branches. For larger branches, the angle can be opened and the light can be introduced. The growth can be controlled by the size of the opening angle of the main branch. On the back of the big branch properly removed, and the rest of the base after the budding branching pendulous fixed, pay attention to put a good position, to spread out to avoid affecting the light, do not pull the stable branch back, so as not to back bald, Sunburn into injury. Lateral branches should be adjusted according to the position and growth potential of the shoots, so that the oblique back, horizontal, oblique and evenly distributed, especially the old and weak trees, we must pay attention to the advantages of growth into results.

The pruning work of apple trees in the spring is mainly to increase the number of middle and short branches, to disperse the polarity, reduce the number of strips, and lay a foundation for stable flowering. Want to send a long branch of the bud early, near, deep, long, on the contrary, want to send a short branch of the bud to be late, far, shallow, short. You can also use the "cut belly" method to fill in the air.

Wangzhi carved bud

For Wangzhi, it is possible to carry out caving before germination. The time is too early and the weather is cold in winter. The cut wounds will dissipate the water in the tree body, and the buds will be dehydrated and frozen, and the severe ones will die. The ideal time should be Start 7-10 days before sprouting. The method of carving buds is determined according to the degree of strong shoots. If the branches are too strong, you can take buds. (If necessary, it can also be used with other means such as branching, pulling branches, etc.) That is, all the buds are engraved except for the thin shoots at the tip of the shoot and the parts of the base that do not require branching. Due to the heterogeneity of the buds, attention should be paid to distinguish between the following two conditions when the buds are sprouted. When the branches are upright, the conditions of each bud are equivalent. When the shoots grow laterally, due to the large difference between the back and back shoots, the buds on the back are easy to germinate, and the back buds are not easy to germinate. Engraved or not engraved on buds. After this treatment, most of the buds on the shoots are germinated due to the sprouting, and the nutrients are diverted, thereby controlling the growth of the shoots.
