A kind of grape pruning method

Abstract

A pruning method for grapes comprises the steps of pruning in summer and pruning in winter. The pruning in summer comprises primary pinching, secondary pinching, shape determination and third pinching. The pruning in winter comprises branch selection, pruning, reservation and trimming time. According to the pruning method for the grapes, space of a frame surface and sunlight are made the most of, early forming of a sapling is promoted, the phenomenon of non-uniform yield in different years of grape production is effectively solved, and the quality and yield of the grapes are improved.

Description

technical field [0001] The invention relates to grape cultivation techniques, in particular to a grape pruning method. Background technique [0002] There are obviously different stages in the growth of grapes in a year. There are eight stages: wounding period, germination period, new shoot growth period, flowering period, berry growth period, berry ripening period, new shoot ripening period and dormancy period. , good tree shape and reasonable pruning are important aspects in determining the way of viticulture. A certain frame requires a certain way of shaping, and a certain way of shaping requires a certain way of pruning. At the same time, a certain way of pruning also requires a corresponding The pruning must ensure that the grape branches and tendrils are reasonably distributed in space, and the branches and tendrils at all levels must be evenly and fully covered on the rack surface, in order to achieve a high yield of grapes. Summer and winter pruning are very importa...

[0003] CN103299875A disclosed a V-shaped grape trellis and a viticulture method on September 18, 2013. A V-shaped left branch and a V-shaped right branch are cultivated at the lower part of the grape vine, and three branches are respectively cultivated on each side branch. Six main branches are formed, and the remaining branches are erased from the base; during winter pruning, the six branches are short-cut at the connecting line corresponding to the lower horizontal arm; after budding in the second spring, each main branch leaves 2-3 buds to lead upright Tie to the connecting line corresponding to the middle cross-arm and the upper cross-arm; for the branches with ears, leave 3-5 leaves on the upper part of the ears for pinching, and the auxiliary shoots that sprout in the leaf axils below the ears are erased from the base, and for the branches above the ears, sprout in the leaf axils 8-10 leaf pinchings are reserved for branches without fruit spikes, and the auxiliary shoots sprouting between the leaf axils are removed from the base; Inconsistency will affect the quality of the grapes, and the ventilation capacity is poor, the underground humidity is high, and the branches, leaves and fruits of the grapes are prone to diseases
