High-branch grafting method for jinlinghong

Abstract

The invention relates to a high-branch grafting method for jinlinghong. The method comprises the specific steps that scions are collected from the middle and upper parts of developmental branches of 1-2 years old which contain 1 or 2 full buds; jinlinghong seedlings of 2-3 years old are selected, anvil cutters are conducted at 30 cm, and the seedlings are used as rootstock; a cutting slip preservation method is to place the scions into paraffin wax for waxing, and the entire scion is wrapped with the wax; a tree is shaped and pruned; the rootstock and the smooth portion of bark near the groundare cut, one side of the rootstock section is cut into long slots, the scions are inserted into the rootstock, and 1-2 buds of the scions are exposed to outside; 3-4 weeks after grafting, the survival condition is checked, and loosening is conducted after one month; water spraying management is conducted on grafted plants; the plants survived are sprayed with a fungicide and an insecticide once amonth; after leaves fall in autumn, the fallen leaves are removed, and a base fertilizer is applied; the invention discloses the high-branch grafting method for the jinlinghong, and the method can improve the water retention of the post-harvest scions, be beneficial to the handling and maintaining of the scions, and improve grafting efficiency.

Description

technical field [0001] The invention relates to a high-branch grafting method of Jinlinghong, which belongs to the field of horticultural production. Background technique [0002] Grafting is one of the common asexual reproduction methods for seedlings. The grafting technique can not only keep the good characteristics of the mother plant but also take advantage of the favorable characteristics of the rootstock. The connected branches or buds are called scions; the grafted plant bodies are called rootstocks or platform wood. Generally select the seedling of tool 2 to 4 buds during scion, become the upper part or the top of plant body after grafting, rootstock becomes the root system part of plant body after grafting. The main factor affecting the survival of grafting is the affinity between the scion and the rootstock, followed by the technique of grafting and the management after grafting. The so-called affinity refers to the ability of scion and rootstock to be the same o...
