Shrunken and weak bud grafting method of jujube tree

Abstract

The invention discloses a shrunken and weak bud grafting method of a jujube tree. A double-tongue grafting method is adopted, and the shrunken and weak bud grafting method comprises the steps: 1, scion cutting, namely pruning a scion which is an annual branch with shrunken buds and two bud eyes to form a scion body which is 10 cm long; 2, cutting a cut at the lower end of the scion body to form afirst slope which is 23 cm long, and upwards splitting a cut on a position 1 / 3 away from the upper part of the lower end of the bottom of the first slope to form a shape like a tongue; 3, cutting offa stock at a set height, then, cutting the cut to form a second slope which is 3 cm long, and downwards splitting a cut on a position 1 / 3 away from the lower part of the top end of the second slope toform a shape like a tongue; 4, mutually inlaying and inserting the scion body and the stock, ensuring that a cambium is aligned during inlaying and insertion, then, binding and sealing a grafting union by using a plastic band; 5, sleeving the upper end of the grafting union with two layers of dark plastic bags; and 6, checking the germination condition of the scion within 15-20 days after grafting, removing buds when the buds on germination positions of bud eyes grow to 5 cm, and then, carrying out secondary bagging. The shrunken and weak bud grafting method has the advantages that the survival rate of jujube tree grafting is increased, and it can be ensured that the jujube tree is successfully grafted even if shrunken and weak buds appear after the jujube tree is grafted.

Description

technical field [0001] The invention relates to a method for grafting jujube trees, in particular to a method for grafting shrunken and weak buds of jujube trees. Background technique [0002] The survival rate of jujube grafting is lower than that of ordinary fruit trees. During the grafting process, when shriveled or weak buds appear, the grafting often fails. Trace it to its cause, be jujube tree bark thin, easily lose water, be the root cause of jujube tree grafting survival rate low; Jujube tree 1-2 year old branch generally has weak bud or shriveled bud, and survival rate is lower. Therefore, in jujube tree grafting process, how to improve the survival rate of shriveled buds or weak buds that occur has been the subject of research by personnel in the field always. Contents of the invention [0003] The purpose of the present invention is to provide a method for grafting jujube shriveled buds and weak buds, so as to improve the success rate of jujube weak buds or shr...
