Minimally invasive bud grafting and head changing method for kiwi trees

Abstract

The invention provides a minimally invasive bud grafting and head changing method for kiwi trees, and belongs to the field of kiwi tree grafting. The minimally invasive bud grafting and head changingmethod for the kiwi trees comprises the specific steps of selecting required seed buds and tree bodies; selecting grafting positions on the tree bodies; performing winter and spring grafting, to be specific, performing pruning in previous winter, peeling the tree bodies in next spring, selecting a grafted variety, transplanting the grafted variety to the peeled positions of the tree bodies, and tying the seed buds with strips; performing autumn grafting; and performing arrangement around the tree bodies, to be specific, cutting off weeds around the kiwi trees by using a sickle, and renovatingsoil after weeding by using a hoe. According to the method, traumas to the kiwi tree bodies are small; the grafting survival rate is high; the growth vigor of the trees is powerful; production startsin the second year, and the fruit-bearing period comes in the fifth year; the tree vigor is good; the yield is high; diseases and pests are prevented; the quality is good; variety renovation is realized in time; and considerable economic benefits are brought, and the method increases the economic benefits by 50% or more in comparison with other grafting methods.

Description

technical field [0001] The invention relates to the technical field of kiwi fruit grafting, in particular to a minimally invasive bud grafting and head replacement method for kiwi fruit. Background technique [0002] At present, the method of grafting is generally adopted for high-grafting of kiwifruit, which causes great trauma to fruit trees, low survival rate, weakened tree vigor after cutting, low yield without growth, and poor quality, which seriously affects the next year's high yield. , The innovative kiwi fruit minimally invasive budding technology overcomes the above shortcomings and lays a good foundation for improving quality and increasing production. [0003] Prior Art Patent Publication No. CN109392486A discloses a method for grafting kiwifruit, which includes the following steps: S1. During the grafting season, select an old kiwifruit tree, cut its trunk horizontally and use it as a rootstock, and set up multiple grafting ports on the saw surface at intervals ...
