High-survival-rate blueberry grafting method

Abstract

The invention discloses a high-survival-rate blueberry grafting method, comprising the following steps: selecting a scion, specifically, in July and August of the year of grafting, selecting a healthyannual Vaccinium corymbosum L. (with a Chinese name of Beigaoconglanmei) branch with a diameter of 6-8 mm and full sprouts, and cutting off tender shoots and leaves for use as scions; selecting a rootstock, specifically, selecting biennial Vaccinium bracteatum as the rootstock, vertically cutting a grafting cut at a branch section, controlling the depth of the cut to be 2-3 cm, spraying a protective liquid to the cut, then inserting the scion into the cut, and conducting wrapping with a plastic film; after grafting buds are alive, completely removing all axillary buds on the rootstock to maintain the absolute advantage of the scion and prompt rapid growth of the scion. The method of the invention adopts the Vaccinium corymbosum L. (with a Chinese name of Beigaoconglanmei) branch as the scion, and selects thebiennial Vaccinium bracteatum as the rootstock, the strains are close, the affinity is strong, and the grafting leads easy survival.

Description

technical field [0001] The invention relates to the field of fruit tree grafting, in particular to a method for grafting blueberries with a high survival rate. Background technique [0002] Blueberry is a berry with high anthocyanin content. The fruit is rich in nutrients. It not only has good nutritional and health effects, but also has the functions of preventing brain aging, strengthening the heart, anti-cancer, softening blood vessels, and enhancing human immunity. , due to the long growth cycle of blueberry, the grafting method is mostly used for propagation at present, and the existing grafting technology mainly has the defects of low grafting survival rate, difficult grafting operation, and fruit quality after grafting can not be better improved. Contents of the invention [0003] The object of the present invention is to provide a kind of high survival rate blueberry grafting method, to solve the problem proposed in the above-mentioned background technology.
