Method for cultivating high-yield high-quality apple trees

Abstract

The invention discloses a method for cultivating high-yield high-quality apple trees. The method comprises the steps of 1) female parent cultivation, wherein variant main branches of 2-year-old honeycrisp apple trees are selected to be top-grafted on a cherry-apple tree and managed until fruit bearing, so that a variant top-grafted female parent is obtained; 2) orchard construction with stocks, wherein a mountainous area where the annual average air temperature is 7.5 DEG C or above, the altitude is 1300-1800 meters, the annual precipitation is larger than 500 millimeters or drainage and irrigation are convenient is selected to construct a T377 dwarf stock orchard; 3) grafting, wherein in the autumn of the current year, branch scions are cut from the variant top-grafted female parent and grafted onto the stocks in the stock orchard to obtain the high-yield high-quality apple trees. The method for cultivating the high-yield high-quality apple trees has the advantages that the cultivatednovel apple tree variety has the advantages of high survival rate, high yield and high quality, and the cultivated novel tree variety can also be grafted as a female parent multiple times, so that itcan be achieved that the apple orchard of a larger area is constructed rapidly, the cost is low, the branches and leaves are small, the yield is stable and high, and the method is of great significance for the development of local forestry fruit production and the improvement of the economic benefits of apple growers.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for cultivating high-yield and high-quality apple fruit trees.
