Pruning methods of kiwifruit trees

Kiwifruit has the effects of beauty, detoxification and clearing intestines, prevention and treatment of depression, and has been loved by many people. With the increasing demand for kiwifruit, more and more people grow kiwifruit. So what are the pruning methods of kiwifruit trees?

Pruning time

The pruning time usually begins 7-10 days after defoliation, and the bleeding period ends one month before the bleeding period, about from December to January. The decision of pruning time is very important, too early nutrient return is not over, too late is easy to affect the bleeding. In addition, according to the characteristics of the local climate, choose the time when the pruning wound is the easiest to heal.

2. Pruning and plastic surgery

In young trees, the amount of pruning is less, mainly in accordance with their own desired frame shape development, to give priority to branches covered with the shelf surface, expand the crown as the pruning principle. But not all the branches are preserved, and it is recommended to cut off the branches of diseases and insect pests and thin branches. For adult trees, we must maintain the backbone structure of the tree body, to ensure the ability to bear fruit, but also have a strong tree potential. The main task of winter shearing is to select fruiting branches to ensure the quantity and quality of retained buds and to make them evenly distributed on the shelf surface.

Attention should be paid to pruning some overgrown branches and leaves, diseased insects, diseased branches and leaves, thin and weak branches and leaves, branches and leaves growing in the shade of the lower layer, branches and leaves growing on the shelf surface, and so on. These branches and leaves need to be cut off.

Third, pay attention to sprouting

There are 1.5-2 fruiting mother branches and 30-35 fruiting buds per square meter, and the number of buds per fruiting mother branch is 15-25, or the fruiting mother branches are cut to the average length of row spacing. Keeping buds reasonably can ensure the quality of flower buds in the coming year and reduce unnecessary waste of nutrition.

4. binding of branches and vines

After pruning the branches and leaves, the branches and vines should be tied up. The binding of branches and vines will directly affect the growth of plants. In the areas prone to freezing injury, the binding time can be set around the beginning of February. It is difficult to distribute the branches evenly by pruning alone, and as they grow, they may grow in all directions. The principle of binding is to make the branches evenly distributed from the inside to the outside as far as possible, the branches on the same wire should be evenly distributed, and the branches on different wires should be interspersed and distributed. When bundling, avoid excessive intersection and overlap, avoid pulling branches, 1-2 lines per branch.

Pruning branches and leaves of kiwifruit is a very important link, which can make a better distribution of kiwifruit nutrients and is more conducive to the growth of kiwifruit.
