What are the latest pruning precautions for kiwifruit trees?

When planting kiwifruit trees, pruning work must be done well, and when pruning kiwifruit, attention should be paid to adjusting the pruning method according to tree vigor and tree age, so as to prevent excessive pruning. After the pruning work is done well, it can improve the ventilation and air permeability of the fruit tree, enhance photosynthetic capacity, and increase yield and quality. However, there are many points we need to pay attention to when pruning. Below, the editor brings you the precautions for kiwifruit pruning. Let's take a look together!

1. Prune according to the tree

When pruning, we should pay attention to observing all aspects of the kiwifruit tree, such as variety and growth years, because due to these different factors, the method and intensity of pruning will change to a certain extent. Many fruit growers do not take these factors into consideration when pruning and prune blindly. In addition, using the same pruning method alone for a long time leads to vigorous trees not growing and causes undesirable phenomena such as alternate bearing.

2. Winter pruning time

Winter pruning is a necessary task that many fruit growers know about, but many times everyone prunes immediately after harvest. Pruning immediately actually wastes a very large amount of nutrients. The period from harvest to leaf drop is the nutrient accumulation period for kiwifruit trees, and the leaves can still continue photosynthesis. If pruning is too early, it will reduce nutrient accumulation and affect the flowering and fruiting of the coming year. However, pruning too late is also not good. If pruning is too late, it will delay the phenological period of kiwifruit and reduce the branching rate, leading to deformed fruit and so on. Generally, pruning about 10 days after leaf drop is best.

3. Dispose of pruned branches

When pruning in winter, most branches will carry diseases, insects, and fungi, and the main pruning targets are also old dead branches, diseased and pest-infested branches, and other such branches. If they are not cut off in time, these branches will become sources of disease and pest transmission in the orchard the coming year. Therefore, after winter pruning, we must dispose of these branches in time. If they are not handled in time, in the second year in spring the disease, insects, and fungi will regain vitality and spread through the branches, seriously affecting planting benefits.

4. Prune decisively

When pruning, be careful not to be reluctant. Many friends cannot bear to cut off those vines that grow robustly and have many branches and leaves. This causes the tree shape of the kiwifruit tree to become chaotic, forming too many excessively vigorous growing branches, and seriously reducing the permeability of the fruit tree. It will not only consume excessive nutrients, but also reduce the flowering and fruiting rate of the kiwifruit tree, increase management workload, and reduce the economic benefits of planting.

5. Pay attention to the bud at the pruning cut

Many friends who are planting for the first time do not pay attention to the condition of the bud at the pruning cut when pruning for the first time. They cut the shoot whenever they see the tip and keep shortening it, resulting in too many branches, forming overly dense branches, and preventing the branches from forming flowers. When shortening, we should appropriately adjust the handling method according to the different branches, and determine it according to factors such as variety and growth vigor. Timely thin out long, dense, crossing, overlapping, and other branches with no growth value to improve the permeability of the fruit tree.

The above is a brief introduction to the precautions for kiwifruit tree pruning. Although pruning work is rather cumbersome, it is the key to ensuring the healthy growth of kiwifruit trees, so everyone must master a correct pruning method. That is all for today's introduction.
