Fruit tree screw type wound bark-breaking and belt-remaining technique

Abstract

The invention relates to a fruit tree wounding screw type skin-breaking belt-remaining operation method. Screw type rotary cutting with the depth to xylem and the width of 2-4mm is carried out on the tree skins of fruit tree trunks or boughs, lateral branches as well as strong branches and vertical branches grown on the boughs. The tree skins are cut to form a spiral ditch winding around the branches for one and a half to two circles with an ascending degree of 4-6 degrees and remain belt-shaped tree skin with the width of 2 / 3 of the branch diameter. The invention controls the thickness of tree crowns and branches, thereby fully adjusting the tree nutrition, increasing the fruit size and nutrition content, improving the coloring rate 2-4 times, inhibiting the generation of plant diseases and insect pests, reducing the times of spraying, promoting the formation of blossom buds, improving the fruiting rate by more than 50%, and causing no problem of dead branches or dead trees. The method is applicable to various fruit trees, in particular to Nanguo pear trees with more obvious effects.

Description

technical field [0001] The invention belongs to the technical field of agricultural fruit tree cultivation and treatment, and specifically relates to a spiral-type operation method for cutting off the bark and leaving bands to control the growth of the fruit tree and promote nutritional regulation by wounding the fruit tree. Background technique [0002] In recent years, the planting area of ​​various fruit trees in my country has been expanding day by day, and fruit trees have become an important pillar for enriching the lives of urban and rural people and increasing the income of fruit farmers. However, problems such as low yield per plant, poor fruit quality, and excessive pesticide residues have become more prominent. In order to effectively solve the above problems, various places have adopted the method of artificially cutting and wounding fruit trees to control the growth of fruit trees, adjust the nutrient supply adjustment mechanism of fruit trees themselves, and ac...

AI Technical Summary

Problems solved by technology

Therefore, it is difficult to grasp and control in actual operation, and it is very easy to damage the phloem, or the stripping width exceeds the standard. Once the grasp is not good, it will cause dead branches or even dead trees, which will bring undue losses to fruit farmers.

If the phloem remains intact, or the peeling width is too small, the wounds of the peeled branches of the fruit tree will heal quickly, resulting in a short inhibition period and failing to achieve the desired effect

Therefore, it has not been generally adopted by the majority of fruit farmers in many years of production practice.
