Outdoor stem grafting method of rest period of fruit tree

Abstract

The invention relates to an outdoor stem grafting method of the rest period of fruit tree. The method comprises the following steps: selecting time and environment, cutting stock, cutting scion, binding, wrapping the top of the scion and the like. The grafting method has the following characteristics: in the rest period and in an outdoor environment, a knife is used to cut a vertical opening on the cortex at the kerf of the stock from top to bottom, wherein the opening has the length of 2-4cm and is deep to the xylem; the scion is cut to a 3-5cm of horse ear-shaped large inclined plane, then the epidermis on the both sides of the back of the inclined plane is cut away to expose the phloem, the tip of the scion is cut to be arrowhead-shaped; the tip of the the scion is placed vertically between the phloem and xylem on the top end of the vertical opening of the stock to ensure that the inclined plane of the scion faces to the xylem; the worker holds the scion in the left hand and uses a tool in the right hand to slightly nail the tip of the scion in the stock and ensure the scion to stand in the stock, then the vertical opening of the stock is tightly pressed by the thumb of the left hand to nail the scion in the stock and ensure that 1-2mm of the upper part of the inclined plane of the scion is exposed; a plastic strip is used to perform tight binding from the kerf and joint of the stock to the lower part of the bud; and a mulch strip is used to slightly wrap the upper notch of the scion. The grafting method has high survival rate, is special for the outdoor stem grafting of the rest period of fruit tree and can prolong the grafting time.

Description

technical field [0001] The outdoor branch grafting method during the dormant period of fruit trees belongs to the field of fruit tree grafting, specifically the outdoor branch grafting and replanting technique during the dormant period of fruit trees. Background technique [0002] At present, in fruit tree branch grafting and replanting techniques, methods such as low-level branching and high-level replanting are generally used. Due to the short grafting time, the skin cannot be separated in winter, and the branch height and diameter of the rootstock are limited, so it can only be used indoors in winter. Seedling grafting is costly, labor-intensive and has a low survival rate. Contents of the invention [0003] The outdoor branch grafting method during the dormant period of fruit trees is to solve the problem of short grafting time in fruit tree grafting technology, and the skin does not leave in winter. The height and diameter of rootstock branches are limited. In winter,...
