Embedded branch grafting method used for fruit tree bare stem branch supplement

Abstract

The invention discloses an embedded branch grafting method used for fruit tree bare stem branch supplement, and relates to a branch management method for fruit tree cultivation. The embedded branch grafting method is used for bare stem branch supplement of a fruit tree and grafting, main shoot change and variety replacement of a big tree. The method is easy to understand, a scion adopts a mode of one peg and one tongue, a grafting opening combines electric drill puncturing and T-shaped bark opening, after the scion is embedded, not only is a stock-scion very firm before the grafting opening heals, but also large-area contact of a stock-scion forming layer with three planes and five lines can be achieved, the grafting opening healing speed is drastically increased, the scion can quickly and comprehensively blend with a stem, therefore, not only are the grafting survival rate and the success rate of tree body transformation drastically increased, but also labor for binding and supporting a scion branch is saved, accordingly the management cost is drastically saved, not only bark can be separated in spring, but also various stemmed fruit trees can be universally applicable, and the method has more important significance particularly for stone fruit trees such as cherries, peaches and the like of which wound are likely to shed pectin.

Description

technical field [0001] The invention relates to a branch management method for fruit tree cultivation, in particular to a branch grafting method for repairing bare branches of fruit trees. Background technique [0002] For all kinds of fruit trees that can peel off the skin and have stems in spring, there are currently 15 grafting methods in production, namely T-shaped budding, xylem budding, embedded budding, sticking budding, square budding, twig grafting, double tongue grafting, and split grafting. , Insert skin connection, plug connection, cut connection, laparotomy connection, lap connection, joint connection, bridge connection. For bald stems, there are only two traditional grafting methods available. One is to use xylem bud grafting in early September after autumn. Affected by the superiority of the top of the tree, germination is often slow in spring and is easily overwrapped by the bark of the rootstock, resulting in weak or no germination, so it is not a suitable ...

For bald stems, there are only two traditional grafting methods available. One is to use xylem bud grafting in early September after autumn. Affected by the superiority of the top of the tree, germination is often slow in spring and is easily overwrapped by the bark of the rootstock, resulting in weak or no germination, so it is not a suitable method for patching bare branches; It can be divided into single-cut lap joint and V-shaped lap joint. Due to the large diameter of the bald trunk, the single-knife lap joint will almost cut off the trunk and cause the upper tree to lose its support. The scion can be inserted directly into the V-shaped incision

However, the V-shaped laparotomy still has its weakness that is difficult to overcome. Although it is less harmful to the trunk than the single-knife laparotomy, it still needs to make a large V-shaped incision, t
