Grafting method of blueberries

Abstract

The invention discloses a grafting method of blueberries. The method comprises the steps of selecting scions, selecting grafting time, selecting stocks, conducting treatment on the scions before grafting, conducting specific steps of grafting and conducing treatment after scion buds are survived. A scion grafting and side grafting method is adopted, highbush blueberries serve as the scions, rabbiteye blueberries serve as the stocks, the adaptability of grafted blueberries to the soil conditions is improved, the requirements of the grafted blueberries for soil porosity are lowered, the growth vigor of the grafted blueberries is promoted, the cold resistance and the disease resistance are strengthened, the blueberries can be planted in a large scale in different soil conditions conveniently, the blueberry fruit is large in size, the seeds are small, the color is kept light blue of the highbush blueberries, and the mouthfeel is good. Due to the fact that thick and strong scions and stocks are selected, the chlorophyll content of mature leaves of the grafted blueberries and the yield of bearing branches grafted through a single blueberry are significantly improved, and output benefit of the grafted blueberries is obviously greater than that of non-grafted plants.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for grafting blueberries. Background technique [0002] Blueberry Blueberry, also known as blue berry, belongs to Ericaceae (Ericaceae), Vacciniodeae (Vacciniodeae) plants.

[0005] Patent CN104067864A discloses a method of grafting southern highbush blueberry with rabbit-eye blueberry as rootstock by budding. This method has high survival rate, strong tree vigor, high adaptability to soil conditions, and resistance to blueberry root rot Strong, but limited by the grafting method, the fruiting period is long, and the yield of a single fruiting branch is low, which limits the output value of blueberries
