Pear compact planting tree shape with high photosynthetic efficiency and shaping and pruning method

Abstract

The invention provides a pear compact planting tree shape with high photosynthetic efficiency and a shaping and pruning method, relates to the technical field of fruit tree cultivation, and solves thetechnical problem of declining of tree crown daylighting rate due to high density planting. The device comprises two plant central trunks, the two plant central trunks extend in opposite directions and are fixed to form X-shaped double trunks, the transverse horizontal spacing between the two central trunks on the ground is 25-35 cm, and the distance between the adjacent X-shaped double trunks inthe same row is 0.8-1.2 m. The tree shape with high photosynthetic efficiency realizes shaping and pruning of X-shaped double-trunk plants by determining fixedly planting points, erecting and stretching lines, fixedly planting, cultivating strong central trunks, cutting buds to promote branching, rack loading, pruning and the like. The utilization rate of light energy of the tree body is improved, improvement of the fruit quality is facilitated, high-density cultivation can improve the efficiency of land use, the yield per mu is greatly increased, the problems of inadequate pesticide application, bagging and difficult fruit picking caused by too high tree body are solved, and the tree shape is especially suitable for construction of sightseeing picking gardens and picking needs.

Description

Technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a densely planted pear tree with high light efficiency and a pruning method thereof. Background technique [0002] Pear belongs to the Rosaceae family. Perennial deciduous fruit trees and trees are widely distributed all over the world. Its edible fruit has high nutritional and medicinal value. Plastic pruning of pear trees is one of the most critical links in pear cultivation and management. Through plastic pruning, the method of shaping the crown into a certain shape is called plastic surgery. [0003] At present, dwarfing and dense planting cultivation is an inevitable trend in the development of fruit tree production. However, due to the lack of more suitable dwarfing rootstocks at this stage, pears still use sparse planting in actual production. With the introduction of the modern dense planting model of arbors, this model has been popularized and applied more and m...
