Pear tree multi-head top grafting improvement and optimization grafting management method

Abstract

The invention provides a pear tree multi-head top grafting improvement and optimization grafting management method. An original pear tree is subjected to grafting improvement, according to multiple heads, 30-60 heads are reserved when the original pear tree is lopped off for grafting, according to top grafting, the heads are grafted at the high positions of side branches, the side branches refer to side branches growing out on a trunk, and according to improvement and optimization, tree form improvement and optimization, layout improvement and optimization and management improvement and optimization are included. The method has the advantages that new varieties are provided with multiple branches and are high in yield and rapid in fruiting; tree forms are large, and the yield is high; a ladder can be placed, pruning, bagging, picking and grafting supplementing are convenient, mechanical operation is promoted, management is convenient, ventilation and light transmission are achieved, the yield is increased, and the quality is improved; the yield is increased by 20% or above by comparing pear trees with layout improvement with pear trees without layout improvement; by means of the method, the net earning per mu can be increased by 5,000 yuan or above.

Description

technical field [0001] The present invention relates to a management method of pear trees.
