Matters needing attention in the latest girdling of winter jujube

The important link in the planting process of winter jujube during ring peeling can effectively promote the fruit setting of winter jujube and ensure high yield, but we should pay attention to the time and method during ring peeling, otherwise it will be counterproductive. So what should winter jujube pay attention to when peeling around? Let's get to know it with the editor.

1. Improper time for girdling

In many fruit growers, regardless of tree age, tree potential and flowering, blind girdling often leads to premature aging of young trees, weaker tree girdling, fruit setting in the early flowering stage, rain infection and so on. This not only does not pass the fruit setting rate, but also affects the plant growth. Therefore, girdling varies according to the number of factors, first of all, look at the tree age, generally girdling is 4-6 years old, trees less than 3 years old should not be girdled; second, girdling is mainly aimed at strong trees, and firmly do not accept weak trees and weak branches; third, look at flowering time, girdling time is closely related to flowering time, flowering quantity and quality, it is appropriate to choose 40% 60% of the full bloom. Fourth, look at the weather, try to choose the average daily temperature of 22: 26 ℃, when there is no rain for more than 3 days, so as to avoid bacterial infection in the wound.

2. Improper girdling.

The width of girdling is too wide, so that the wound does not heal for a long time, while some are too narrow and heal in less than half a month, and some of them are uneven, the phloem is not removed, and the xylem is damaged, which can not achieve the effect of girdling. It will also have a great impact on plant growth. Therefore, girdling should first control the position of girdling, starting from the trunk girdling about 20 centimeters from the ground, and then controlling the girdling width, which is generally 1/10 or 1/8 of the direct width of the branch. Finally, it is necessary to control the smoothness and depth of the ring stripping mouth, and the ring peeling tool should be sharp and the ring peeling depth should be up to the xylem, but the xylem should not be damaged, and then the phloem should be removed completely, so that the wound is smooth and smooth, and the lower edge of the ring stripping mouth is beveled to prevent stagnant water.

3. Improper wound protection

Some fruit growers neglect management after girdling, so that the wound is directly exposed to the outside, which will make the wound harmful to diseases and insect pests. In the case of high temperature, drought and rain, the wound is very prone to decay and necrosis. There are also some fruit growers who wrap the wound with plastic film after ring peeling, causing the wound to heal ahead of time, resulting in a large number of fruit drop. Three days after girdling, the wound should be dried and drained in case of rain to avoid bacterial infection. after that, disinfection and sterilization should be sprayed every other week. after girdling for 15-20 days, gibberellin should be smeared on the wound and bandaged with plastic sheet. the sprouts of the wound should be removed in time to reduce nutrient consumption.
