Blueberry grafting method

Abstract

The invention relates to the field of blueberry planting, in particular to a blueberry grating method. The method comprises the steps that a dormient branch, without buds, of a high-grove blueberry plant is selected as a scion, and a wedge-shaped inclined surface is cut at the lower end of the scion; a rabbiteye blueberry base growing branch is selected as a stock, and a grafting position is selected at a smooth, flat and straight position of the stock; the scion is soaked with clean water and then soaked in a culture medium, the scion is trimmed, and 3-4 buds are preserved; grafting is carried out 3-5 days before germination of the buds of the branch in early spring; the lower end of the scion is slightly inserted into a seam of the strip-shaped skin layer upper end; all auxiliary buds on the stock are removed with the hands to maintain the absolute predominance of the scion, and quick growth of the scion is promoted. By means of the blueberry grafting method, much callus can be easily generated to be connected with much callus generated on the left side and the right side of the inclined surface of the scion, so that the scion in the grafting method can survive more easily than that in other methods, the survival rate is generally 98% or higher, the fruit bearing period can be obviously shortened, and meanwhile the fruit bearing yield can be increased.

Description

technical field [0001] The invention relates to the field of blueberry planting, in particular to a method for grafting blueberries. Background technique [0002] Blueberry, the fruit is blue, with a layer of white fruit powder on the surface, the flesh is delicate, the taste is sweet and sour, and it has a unique fragrance. Blueberries are rich in various trace elements and vitamins, and have various health effects such as enhancing immunity and delaying aging. In addition to being eaten fresh, blueberries are also widely used in industries such as food and pharmaceuticals. The economic benefit is remarkable, and the market prospect at home and abroad is very broad. Blueberry cultivation began in the United States in the 20th century. The history of blueberry cultivation in my country is relatively short, and it is currently in a period of rapid development. [0003] my country's research on blueberries began in the 1980s. The introduction and cultivation of blueberries ...

Problems solved by technology

During the planting process of existing blueberries, the soil needs to be improved to adjust the pH of the soil to meet the needs of blueberry planting. Soil improvement is a very important link in the cultivation of blueberries. During the cultivation of existing blueberries, There are often situations such as improper fertilization that cause blueberry seedlings to burn roots, and because the existing blueberry cultivation methods are not accurate enough, resulting in slow rooting, low survival rate, and long cultivation period in the process of blueberry planting, resulting in blueberry failure. The yield is relatively low, which reduces the economic benefits, seriously hinders the sustainable development of blueberries, and cannot meet the needs of planting

[0004] Chinese patent CN 104067864 A discloses a method for grafting southern highbush blueberry with rabbit-eye blueberry as rootstock by budding. The resistance of blueberry is strong, but limited by the grafting method, its fruiting period is long, and the yield of a single fruit is low, which limits the output value of blueberries
