There is a common phenomenon of bleeding in spring, which is mainly due to the outflow of tree sap from the wound, the loss of a large amount of nutrients, the reduction of yield and the death of the whole plant. So what is the cause of the bleeding? What should I do with it? Let's take a look at the detailed introduction.

I. causes of bleeding

Raisin is a common phenomenon in spring when the temperature of the soil reaches 6-10 degrees. Generally, when the soil temperature reaches 6-10 degrees, the root system of the seed begins to move, and the sap and nutrients of the tree will be transported along the xylem to all parts of the tree. If you encounter a wound in the process of transportation, it will flow out and drip water like rain when it is serious, which is extremely disadvantageous to the growth and development of raisins and should be prevented and treated in time.

II. Prevention and control measures

1. Correct pruning

For the pruning of branches should not be too early or too late, too early will lead to the tree nutrients did not return to place, resulting in waste, too late will hurt its, a large number of nutrients will flow out with the wound, resulting in excessive consumption of nutrients. The best pruning time is generally 3-4 weeks after defoliation, especially between the beginning of December and the end of December. After pruning, we should also pay attention to protect the wound and make it heal as soon as possible.

In order to prevent bleeding, the best way is to protect the wound, after pruning, you can use white latex or sealing oil mixed with stone sulfur mixture residue to apply to the wound, which is convenient and fast, low cost and good effect.

3. Improve the resistance of trees.

Watering and fertilizing in time in spring to improve the cold resistance of trees, generally combined with fertilization to irrigate plants, each plant applied 0.25 kg ternary compound fertilizer, mainly potash fertilizer, to a small amount of biological bacterial fertilizer and trace elements, can effectively improve the resistance of plants to avoid freezing injury caused by a large number of wounds.

4. Clear the garden in a comprehensive way

Thorough cleaning of the garden should be carried out in winter, first of all, the weeds should be cleared, then the residual branches, fallen leaves and weeds in the garden should be burned, and the eggs on the branches and vines should be artificially scraped to reduce the source of diseases and insect pests, so as to avoid injuries caused by diseases and insect pests.
