How to deal with kiwifruit bleeding? The latest method is here
Kiwifruit has a very large planting area in our country, and when planting kiwifruit, many problems often occur. Among them, bleeding is one. Bleeding is very unfavorable to the growth of kiwifruit. It seriously affects the yield and fruit quality of kiwifruit, thereby reducing economic benefits. So what harm does kiwifruit bleeding cause? And how should it be dealt with? Below, the editor will briefly introduce it to everyone. Let's take a look together!
1. Harm of bleeding
During the growth of kiwifruit, the bleeding period is actually one of its growth stages, and it is generally a normal phenomenon. However, this only refers to when the bleeding is relatively minor. If the bleeding is minor, then the harm to the kiwifruit tree is very small. But if the bleeding is relatively serious, then it is very unfavorable to the growth of the kiwifruit tree. It will not only reduce the number of flowers and fruits and lower fruit quality, but also cause the tree vigor of the kiwifruit tree to decline. And according to surveys, severe bleeding generally occurs in vigorous trees, while trees with weaker vigor generally do not have bleeding. So we can judge the tree's growth vigor based on bleeding.
2. Causes of bleeding
When planting kiwifruit, if the temperature continues to rise, then the inside of the kiwifruit tree will begin to become active. The roots gradually transport water to the upper part of the fruit tree, and when transporting water, because wounds were left during winter pruning the previous year, part of the water will flow out from the wounds, thus forming bleeding. The bleeding period can actually be regarded as a phenological period in the growth of kiwifruit, and it is basically a normal phenomenon. But if the bleeding is too severe, then it is very unfavorable to tree vigor, so everyone should pay more attention.
3. Preventive measures
If you want to reduce the bleeding phenomenon of kiwifruit, then prevention should be the main approach. First, we must do a good job in winter pruning. Winter pruning can be carried out from about ten days after the kiwifruit tree sheds its leaves until February of the following year, and pruning must stop after entering March. During winter pruning, if large branches are pruned, then after pruning, the wounds should be allowed to dry as soon as possible. Then apply an appropriate amount of sealing glue to the wounds to reduce bleeding and avoid excessive bleeding.
After spring arrives, observe the growth of the kiwifruit tree frequently. If bleeding is found at pruning cuts, then sterilize in time and apply an appropriate amount of healing agent to promote the wounds to heal as soon as possible. Then we should do a good job in watering according to the soil moisture condition, and it is best to delay the watering time to reduce bleeding. But if the bleeding is too little, then it may be that the kiwifruit tree roots are distributed too deep, or it has root rot, etc. So corresponding measures should be taken in time to restore tree vigor and enhance root growth capacity. Finally, after clearing the orchard each winter, the trunks should be whitewashed to avoid frost damage to the trunks and reduce infection by pathogens.
The above is a brief introduction to how to deal with kiwifruit bleeding. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
