Rigid branch grafting and rapid grow seedling technique for grape

Abstract

Disclosed a new technology for fast growing seedling by grafting hard branch of grape, is characterized in the following method and steps : (1) building hotbed for growing seedling of grape and preparing heating means; (2) selecting high quality of hard branch for grafting and stock with developed and strong root; (3) shearing the stock in its 5-8 cm above the root, and making a vertical cut in the middle of said cut; cutting a surface with obliquity from 2.5 cm of lower graft to the bottom, and cutting a tangent plane in the back of graft at the base with two flower buds cutting in its upper part; introducing the oblique plane of graft into the stock along the cut with respect to at least one cambium of two sides, and packing securely the combination of the top part of stock and the grafting cut of the graft with plastic; (4) putting the seedling grafted on hotbed keeping a certain damp condition of root and a certain temperature condition around grafting combination, and the grafting combination will heal in twenty to thirty days therefore the seedling can be cultivated out. Said technology is in advantages of low cost, fast cultivation, novelty, easy graft, and survival rate than 95 %.

Description

technical field [0001] The invention relates to a new technology for rapid seedling cultivation, specifically discloses a new technology for rapid seedling cultivation of grape hard branch grafting, belongs to the technical field of forest fruit grafting seedling breeding and production, and is widely applicable to forest fruit grafting. Background technique [0002] Before the present invention, grape seedlings mostly adopt traditional methods of raising seedlings such as pruning and rooting, cuttings, and some use green branch grafting to raise seedlings. The above methods lead to slow growth and development of grapes, low survival rate, long cycle, and damage to parts when transplanting seedlings. The root system has to go through a slow seedling period, which delays growth and fruiting. There is a long period of time for grafting seedlings in the first year, planting in the second year, and fruiting in the third year. It is labor-intensive, time-consuming, costly, and slow...

Problems solved by technology

[0002] Before the present invention, grape seedlings mostly adopt traditional methods of raising seedlings such as pruning and rooting, cuttings, and some use green branch grafting to raise seedlings. The above methods lead to slow growth and development of grapes, low survival rate, long cycle, and damage to parts when transplanting seedlings. The root system has to go through a slow seedling period, which delays growth and fruiting. There is a long period of time for grafting seedlings in the first year, planting in the second year, and fruiting in the third year. It is labor-intensive, time-consuming, costly, and slow. , it is not suitable for the development needs of variety diversification, planting scale, production standardization, management modernization and high-end and high-quality products, which reduces the competitiveness of my country's grape products in domestic and foreign markets
