Quick reproduction method of grape grafting seedlings

Abstract

The invention discloses a rapid propagation method of grape grafted seedlings. The winter grape hard branch is taken as a rootstock and a scion. Through an appropriate temperature, the graft union is firstly in thermal synthesis. Afterwards the rootstock surface is heated for the callus of the graft union. A medicament with an proper formula is adopted for the dipping of the injured face to facilitate the healing of the graft union and the wound healing and rooting of the rootstock lower part, in which the step is that the first is the rootstock branch treatment, the second is the ear shoot treatment, the third is the inlaying grafting and connecting of the rootstock branch and ear shoot, as well as the ear opening bandaging, the fourth is the heat wound healing of the graft union, the fifth is the wound healing and rooting of the rootstock opening, the sixth is the transplanting and container transplanting seedling. The invention is simple and practical with convenient operation, short seedling cycle which only needs 1 to 8 months, high survival rate which can be more than 90%, low production cost, strong seedling growth, long growth period, fully aging branches and tendrils and good seedling quality, thereby the mechanical large-scale factory production is facilitated.

Description

technical field [0001] The invention relates to the technical field of rapid seedling cultivation of horticultural plants, and more specifically relates to a method for rapid propagation of grape grafted seedlings. Background technique [0002] The grafting of grapes is an effective measure to improve the resistance of grapes to disease and insect pests and drought, cold, salinity, and waterlogging disasters. At the same time, the use of excellent rootstocks can also improve the quality of fruits, stabilize grape production, and improve economic benefits (1, Yang Zhiyuan, "Preliminary Report on the Applicable Rootstocks of Grape Fujiminori", Chinese and Foreign Grape and Wine, 2002, (6): 28-30; 2. Xu Hong et al., "Preliminary Report on Grape Rootstocks and Variety Drought Resistance Identification", Chinese Fruit Trees, 2004 (2) : 30; 3.

AI Technical Summary

Problems solved by technology

When Yang Zhiyuan summed up the practice of grape seedling cultivation in Zhejiang Province, he believed that in the production of grape green branch grafting seedlings, the main problem is that the optimum period of green branch grafting is short. In order to achieve the most suitable rootstock thickness for grafting, and until mid-June is generally a month-long plum rain period in Jiangsu and Zhejiang regions, it is inconvenient to graft, therefore, the suitable green branch grafting period is short

(Sun Haisheng, Wang Zhongyue, etc., Experiments on in vitro Grafting of Grape Hard Branches, Friends of Fruit Farmers, 2007, 4:8), and at the same time, Sun Haisheng et al. introduced methods due to the premature germination of grafts, which is prone to the late stage of insufficient water and nutrient supply after transplanting. Dead seedlings, at the same time, due to the premature and long rootstock of this method, it is inconvenient to transplant, and its practicability in production needs further application verification
