Yangtao actinidia tree high-scion and head-changing method

Abstract

The invention provides a yangtao actinidia tree high-scion and head-changing method which includes the steps: sequentially planing a position needing head-changing of the side face of a main vine of aracked yangtao actinidia tree from main vine branches to form a planed surface of the racked yangtao actinidia tree and obtain tongue-shaped chips of the main vine; sequentially planing a scion branch along the direction of the branch from the lower portion of a scion bud to form a planed surface of a scion and obtain tongue-shaped chips of the scion branch; inserting the tongue-shaped chips of the scion branch into the tongue-shaped chips of the main vine and tightening the tongue-shaped chips to obtain the yangtao actinidia tree after high-scion and head-changing; removing branches emergingon the periphery of the head-changing position; repeatedly pinching bearing mother branches bearing fruits in the first year; pruning away main vines of original varieties in winter after harvesting;retaining main vines of new varieties; forming bearing mother branches of the new varieties in the second year; bearing the fruits of the new varieties. The method overcomes the shortcomings that large wounds of yangtao actinidia trees are caused, tree vigor is difficulty restored and yield is low in traditional grafting. Yangtao actinidia variety replacement and high and stable yield are simultaneously achieved, survival rate is high, and current yield and return cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of grafting, and in particular relates to a method for high grafting and head replacement of kiwifruit trees. Background technique [0002] Kiwi fruit tree high-splicing replacement is a good way to quickly change varieties to achieve industrial structure adjustment, early production, and early benefits. However, the traditional method is to saw off the branches on the main vine and leave only the trunk. Remove the branches on the main vine and only leave For the main trunk, adopt the method of splitting and grafting on the trunk to replace the head or remove the head on the main branch of the main vine and then graft new varieties. This method is equivalent to a major operation for kiwifruit trees. Many branches are removed and grafting is difficult. , the survival rate is low, not only is there no output in the year, but also the grafting time and method are not suitable, and the phenomenon of dead trees w...

This method is equivalent to a major operation for kiwifruit trees. Many branches are removed and grafting is difficult. , the survival rate is low, not only is there no output in the year, but also the time and method of grafting are not suitable, and the phenomenon of dead trees will occur.
