Grafting method of improved inferior fruit tree

Abstract

The invention provides a grafting method of an improved inferior fruit tree. The method comprises the first step of etching square lines in the periphery of spore; the second step of cutting a square peel mouth on the cortex of a stock so as to make wood of the stock exposed, wherein the shape of the peel mouth is matched with the shape of a bud slice; the third step of conducting grafting at the temperature of 20-35 DEG C, putting the bud slice into the peel mouth, and making gaps of 5-8 mm exist between the two broadsides of the bud slice in the radial direction and the edge of the cutting mouth. According to the grafting method of the improved inferior fruit tree, when the bud slice and the cutting mouth of the stock are subjected to grafting, certain gaps exist between the two sides so that the water in the cortex of the stock cannot run off from the gaps can be guaranteed, and the purpose that redundant nutrient solution can be drained out through the gaps can be guaranteed at the same time. Since grafting is conducted at the high temperature of 20-35 DEG C, the application duration of the grafting method is long; grafting can be conducted from April to July every year, and at this temperature, callus between the bud slice and the stock grows quick.

Description

technical field [0001] The invention relates to the technical field of plant grafting, in particular to a grafting method for improving inferior fruit trees. Background technique [0002] Grafting is to graft the branches or buds of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant. Grafting is of great significance to the reproduction of some fruit trees that do not produce seeds (such as persimmons, some varieties of citrus). Grafting can not only maintain the excellent traits of scion varieties, but also utilize the favorable characteristics of rootstocks to achieve early fruiting, enhance cold resistance, drought resistance, and resistance to diseases and insect pests, and can also economically utilize propagation materials and increase the number of seedlings. If it is found that the planted fruit tree produces less fruit or no fruit, the fruit tree needs to be improved by grafting. In the existin...

Problems solved by technology

Because fruit trees higher than 2 meters are prone to incompatibility fractures at the interface after grafting, resulting in an increased risk of graft failure

Therefore, it takes a certain amount of planting time to judge whether it is a low-quality fruit tree, resulting in fruit trees higher than 2 meters, especially fruitless fruit trees that are five to six years old, which cannot be improved and can only be cut down.
