Grafting method for Qinghong apricots

Abstract

The invention belongs to the field of grafting, and particularly relates to a grafting method for Qinghong apricots. In order to solve the problems that in the grafting reproductive process of Qinghong apricots, the T-shaped bud grafting, cleft grafting and other methods are adopted, the survival rate is quite low, and the breeding speed and quality are affected, the invention creatively providesa grafting method for Qinghong apricots, and the method can remarkably increase the grafting breeding survival rate, increase the breeding speed and improve the nursery stock quality. In order to achieve the purpose, by adopting the technical scheme, the grafting method for Qinghong apricots comprises the following steps of S1 selecting stocks, S2 selecting scions, S3 performing advanced treatmenton the stocks and the scions and S4 performing grafting on the stocks and the scions and performing excessive binding.

Description

technical field [0001] The invention belongs to the field of grafting, and specifically relates to a method for grafting green apricots. Background technique [0002] Economic forest is a forest whose main purpose is to produce fruit, edible oil, industrial raw materials and medicinal materials. Qinghong apricot is a kind of economic forest. In order to maintain the excellent genotype of its mother tree, it must be propagated by grafting. However, in production practice, Commonly used methods such as T-shaped budding, xylem-embedded budding, and cut grafting are not only cumbersome grafting procedures, but also have low survival rates, which affect breeding speed and quality. [0003] Although T-shaped budding (shield-shaped budding) has a high reproduction coefficient, high grafting survival rate, and no material waste, but because the budding comes from the branches that were drawn in the same year, in the alpine region, the buds are often used after August, so wait here. ...

Problems solved by technology

[0002] Economic forest is a forest whose main purpose is to produce fruit, edible oil, industrial raw materials and medicinal materials. Qinghong apricot is a kind of economic forest. In order to maintain the excellent genotype of its mother tree, it must be propagated by grafting. However, in production practice, Commonly used methods such as T-shaped budding, xylem inlay budding, and cutting grafting are not only cumbersome grafting procedures, but also have a low survival rate, which affects the breeding speed and quality.

[0003] Although T-shaped budding (shield-shaped budding) has a high reproduction coefficient, high grafting survival rate, and no material waste, but because the budding comes from the branches that were drawn in the same year, in the alpine region, the buds are often used after August, so wait here. After timely grafting, when the buds start to germinate and the branches are drawn, the temperature begins to drop, the maturity of the new branches is poor, and the shoots are severely drawn during the winter, resulting in a decrease in the survival rate of grafting

[0004] The scion for split grafting is made of annual branches, and the buds are well developed. The grafting time is in spring. As long as the grafting survives, the seedlings can be grown in the same year, but the scion is longer (8-10 cm), and it needs 2-3 buds. Therefore, the waste of grafting materials is serious. At the same time, the grafting procedure is complicated, which affects the speed of grafting. The healing of the grafted part is not ideal, and it is easy to split, resulting in a decrease in survival rate.

[0005] The scion of the traditional cut grafting adopts annual branches, the buds are well developed, and the grafting time is in spring. As long as the grafting survives, the seedlings can be formed in the same year, but the contact surface between the scion and the rootstock is limited, and the callus is formed slowly. The part is not firm and easy to split, resulting in a decrease in survival rate
