In-vitro grafting method

Abstract

The invention discloses an in-vitro grafting method. According to the in-vitro grafting method, a scion and a stock are both in-vitro materials. After grafting, the stock which the scion is grafted onto is rapidly transplanted to a seedling bed, and the purpose that rooting of the stock and union of a connector are synchronous is achieved. By the adoption of the in-vitro grafting technology, grafting is easy to operate, centralization and industrialization of grafting are achieved, and multiple varieties with a low survival rate during traditional grafting or distant varieties can have a high survival rate after the environment optimization technology is adopted; especially, a good promoting function is achieved on inducing of callus tissue of a cut and formation of a fusion vascular bundle between heterogeneous cells, supplementation of a nutrient solution and exogenous hormones can be achieved in the integrally optimized seedling bed, and the union survival rate is greatly increased; the in-vitro grafting method has also the positive function on rapid cultivation of various induced seedlings during breeding.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an in vitro grafting method. Background technique [0002] Traditional grafting is carried out on the rootstock of planting in the ground mostly, and after grafting must wait for the grafted branches to survive before transplanting. The cultivation time of rootstock plus the cultivation time of grafted seedlings makes the entire seedling cultivation cycle too long, some varieties need 2-3 years, and the short cycle also needs 1 year, which greatly affects the speed and efficiency of seedling cultivation. And a rootstock tree can only be grafted once, and a large number of rootstock trees need to be cultivated for grafting. In addition, the survival rate of traditional grafting is greatly affected by the external environment, such as changes in climate factors such as unstable humidity, temperature, and light, which will affect the survival rate, especially in rai...

AI Technical Summary

Problems solved by technology

The cultivation time of the rootstock plus the cultivation time of the grafted seedlings makes the entire seedling cultivation cycle too long. Some varieties need 2-3 years, and the short cycle takes 1 year, which greatly affects the speed and efficiency of seedling cultivation.

Moreover, a rootstock tree can only be grafted once, and a large number of rootstock trees need to be cultivated for grafting.

In addition, the survival rate of traditional grafting is greatly affected by the external environment, such as changes in climate factors such as unstable humidity, temperature, and light, which will affect the survival rate, especially in rainy weather or high temperature and drought. greatly reduced
