A method for shaping the fence shape of one peach tree with multiple stems

Abstract

The invention discloses a peach tree wall training shaping method capable of achieving one plant with multiple trunks. The method comprises the following steps: performing row forming in the north-south direction, and adopting plant and row spacings of 6 m x 3 m; during the growth of peach trees, retaining 2 trunks for each plant and 2-3 main branches for each trunk, cultivating fruiting branchesdirectly on each main branch, and adopting single branch renewal without cultivation of branch groups; selecting long and thick branches in the north-south direction for branch pulling, adopting thepulled branches as trunks which are parallel to the ground, selecting thick and long branches on the horizontal trunks, spraying paclobutrazol or PBO to crowns, adopting long-tip pruning for winter cutting, performing summer cutting in the growth season of the second year, cultivating thick and long branches growing from the horizontal branches continuously, retaining 5-6 leaves on newly developedrough branches from the main branches, performing short cutting or direct thinning removal on the newly developed rough branches, and performing retraction on old branches without fruit setting again; and when winter cutting is conducted in the second year, performing thinning removal on old branches with fruit setting in the year, managing new, thick and strong branches without timely growth, retaining the other newly formed fruit setting branches for fruit setting in the next year, and performing such management every year.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a method for shaping the shape of a peach tree with multiple stems. Background technique [0002] At present, the main tree shapes used in peach production in my country are: trunk shape, natural happy shape, etc. The main problem is that the shaping and pruning technology is relatively complex, and it is difficult for untrained fruit farmers to master; the formation is slow, and the early yield is not high; The canopy is too open and the bearing capacity is not enough. After entering the high-yielding period, it is easy to stagnate, resulting in poor working environment in the orchard, poor ground illumination, and no grass. Difficult to mechanize, etc. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a method for shaping the shape of a peach tree with multiple stems. By conforming to the growth law of peach trees, creatively combining the ...
