Problems solved by technology

[0005] The present invention aims at the outstanding problems of high temperature and high humidity in summer, abundant rain, and vigorous growth of Qingti grapes. After the grapes bloom, the fruit set rate is low, resulting in sparse fruit ears and poor commerciality, thereby affecting the yield and quality of grapes. carry

Embodiment Construction

[0019] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] Implementation time: 2010-2011 Selected varieties: 8-year-old Qingti grapes cultivated in flat sheds. Qingti grapes are cultivated on large horizontal sheds. With the expansion of the vine canopy, gradually thinning, the grape plants are reduced year by year, and only the surface of the vines is maintained. With a certain leaf area index, the 8-year-old Qingti grape occupies an area of ​​about 350 square meters.

[0021] Use long shoot pruning. During the period when the tree vigor is relatively vigorous, carry out appropriate thinning and pruning. For the excessively long new shoots that grow vigorously, cut off about 1 / 3-1 / 5 of the tip to ease the tree vigor.

[0022] With the steady gr...

Abstract

The invention discloses an ear clipping method for improving the fruit setting rate of green grapes. The purpose of improving of the fruit setting rate of the green grapes is achieved through the steps of ear clipping, hormone treatment, manual fruit thinning and the like. By means of the treatment, spica growing points are clipped, and hormone distribution conditions in spica are adjusted. By means of the hormone treatment, the growth rate of ears is controlled, the fruit thinning can be considered and achieved, the trouble of manual fruit thinning is reduced, the fruit setting rate of the green grapes is improved obviously at last, and the effect is better if the spica is clipped after bloom. In addition, the clipped spica is regular in serial type and high in commodity.

Description

technical field [0001] The invention relates to a sorting method of grape flower spikes, in particular to a sorting method for improving the fruit setting rate of green grapes. [0002] The ear method belongs to the technical field of viticulture management. Background technique [0003] With the improvement of horticultural cultivation technology, my country's viticulture has developed rapidly, and viticulture technology is also becoming more and more perfect. Due to the vast territory of our country, the cultivation techniques and cultivation modes vary greatly from place to place. kind. Originating in California, USA, it is a grape variety bred by researchers from California State University in the 1970s through hybridization experiments. Since the introduction of this variety in my country in 1987, except for Heilongjiang and Jilin, other provinces in the northern region have introduced and cultivated it, especially in the southern part of Northeast China, North China a...
