Chinese pear horizontal shed frame single main branch conjoined comb-shaped shaping cultivation method

Abstract

A Chinese pear horizontal shed frame single main branch conjoined comb-shaped shaping cultivation method belongs to a pearl tree cultivation method. The Chinese pear horizontal shed frame single main branch conjoined comb-shaped shaping cultivation method is characterized by comprising the following steps of (1) rationally selecting plant and line intervals, (2) fixed-planting one-year-old grafted seedlings, (3) culturing large seedlings for conjoined grafting, (4) building the horizontal shed frame, (5) fixing main branches under the shed and conducting end-to-end connection for adjacent new tree branches, (6) conjoined grafting adjacent trees, (7) nursing fruiting side branches, (8) rationally fruiting and (9) updating fruiting side branches. In the (5) step, under iron wires fixing the main branches 15 to 20cm under the shed, new branches of adjacent trees are end-to-end connected; between the end-to-end connected new branches of the adjacent trees, tip ends of the tree behind works as spike wood; new branches of the tree front works as a basic block close to the spike wood, so the main branches of the adjacent trees can be connected to an integral in a horizontal straight line way. Compared with the prior art, the Chinese pear horizontal shed frame single main branch conjoined comb-shaped shaping cultivation method is simple and easy to promote and requires less labor; and production labor cost can be reduced by over 30%.

Description

technical field [0001] The invention belongs to a pear tree cultivation method, in particular to a "comb-shaped" plastic cultivation method for a sand pear horizontal scaffolding with a single main branch conjoined body. Background technique [0002] Pear trees are one of the main fruit trees in my country, and the cultivated area and output of pear trees rank first in the world. Among various fruit trees in my country, pear tree area and output are second only to apples and citrus, ranking third. The south of the Yangtze River is a tropical and subtropical pear area, mainly cultivating sand pear varieties; the Yunnan-Guizhou Plateau pear area also mainly cultivates sand pears. The prominent problems in the cultivation of pear trees in our country are that the management level is poor, the yield per unit area is low, and the quality of pear fruit is low; the growth of young trees is weak, and it is too late to enter the high-yield period. Pear trees in Japan and South Kore...

[0004] Though the pear tree horizontal scaffolding cultivation of the prior art dwarfs the canopy than the traditional arbor cultivation, facilitates the operation, and improves the fruit quality, but the pear tree that has changed the upright growth habit is the horizontal scaffolding cultivation, and if the apex of the main branch cannot be adopted The technical measures have always maintained its growth advantage, an
