Method for grafting pomegranates with high survival rate

Abstract

The invention provides a method for grafting pomegranates with high survival rate, and belongs to the technical field of agricultural planting. The method includes a) selecting a nursery, performing soil preparation and deep excavation, filling holes with breeding media, applying base fertilizer, and constructing a seedbed; b) disinfecting pomegranate seeds before accelerating germination, sowingthe seeds to the seedbed, and selecting pomegranate seedlings as grafting stock seedlings in the next year; c) selecting adult improved-variety pomegranate trees to collect scions, cutting the scionsto form tongue-shaped cut surfaces, applying beeswax to the cut surfaces, and storing the scions in a chilling storage; d) performing grafting according to a cleft graft process, applying repair agents to the edges of joints between the scions and stocks, and tightly tying the scions and the stocks; e) performing management after grafting. The method has the advantages that the pomegranate seeds can wake up early, and the sprouting rate and the seedling survival rate can reach more than 98%; separation layers formed between the scions and the stocks due to tannin are greatly weakened, and thesurvival rate of the grafted seedlings can reach more than 99%; the fruit yield of the grown grafted pomegranate seedlings is remarkably increased, and the economic value is very high.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a pomegranate grafting method with high survival rate. Background technique [0002] Generally speaking, grafting technology is a cultivation method in which the roots that become the rootstock and the shoots that become the scion are composed of close relatives with different genomes, and their excellent abilities are combined. Grafting has been recorded in citrus cultivation in China since about 4000 years ago. Its original purpose was to give maintenance or early flowering points to excellent individuals, but it was known that there were rootstock species with better root systems, and a grafting method that preferentially used them was adopted. Grafting is of great value in perennial woody plants, but it is also used in annual crops such as tomatoes, eggplants, and cucumbers, and has the advantage of being associated with increased productivity by us...

Problems solved by technology

However, in this inventive method, the cleave of the scion is directly inserted into the cleave of the rootstock, aligned with the cambium, inserted tightly inwardly, and the interface is wound and tied with a film to obtain grafted seedlings, the cleave of the scion to which it belongs, and the cleave of the rootstock. All of them contain a layer of tannic acid, which solidifies into a layer of isolation layer, which will affect the full contact between the scion and the rootstock and the full exchange of water and nutrients. In severe cases, it will cause dead seedlings.
