Problems solved by technology

[0004] The present invention aims at the outstanding problems of high temperature and high humidity in summer, abundant rain, and vigorous growth of Kyoho 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. The whole panicle method of fruit setting rate of Kyoho grape

specific Embodiment

[0020] Selected varieties: 20-year-old Kyoho grapes cultivated in flat sheds.

[0021] Kyoho grapes are cultivated on large horizontal trellises. With the expansion of the grape canopy, gradually thinning, the grape plants are reduced year by year, only to maintain a certain leaf area index on the surface of the grape trellises. The 20-year-old Kyoho grapes occupy an area of ​​350m 2 about.

[0022] 1. 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.

[0023] 2. With the steady growth of the tree, the length of the fruiting mother branch in winter is about 20-120cm, and about 1 / 3 of the apex of the fruiting mother branch is cut off, leaving 3-4 fruiting mother branches per square meter.

[0024] 3. Carry out management such as bud smearing, new shoot luring, bagging, and pest control...

Abstract

The invention discloses a panicle arrangement method for improving a Kyoho grape setting rate. The method is suitable for Kyoho grape cultivation in the area where rainwater is abundant, grapes grow strongly, and the weather is hot and humid highly in summer. The method comprises the steps that panicle is arranged in the early flowering season of Kyoho grapes, namely blooming with 0-30% and 2-6 days after flowering, subsidiary panicle and 2-3 branch peduncles at the upper portion of the panicle shoulder are cut, and the tail portion of 2cm of the panicle is cut at the same time; 13-15 branch peduncles are reserved on the whole panicle. After the panicle is arranged and cut well, the width of the panicle shoulder is kept to be 6-7cm, the width of the panicle tail is kept to be 3-3.5cm, and the panicle length is 12-13cm. By the arrangement of the panicle at the right moment, distribution of plant hormones in the panicle is adjusted, nutrient competition among flower buds in the flowering process is reduced, the fruit setting rate is improved, fruit clusters after flowering are trim and compact, appearance is attractive, and the commodity characteristic is improved.

Description

technical field [0001] The invention relates to a method for arranging flower spikes of Kyoho grapes, which belongs to the fruit tree cultivation technology, and is especially suitable for the cultivation of grape varieties with heavy flower and fruit drop. Background technique [0002] With the improvement of horticultural cultivation technology, the viticulture in my country has developed rapidly, and the viticulture technology has also been perfected day by day. Due to the vast territory of our country, the cultivation techniques and cultivation modes vary greatly from place to place. Kyoho grape, as an earlier variety, Because of its high disease resistance, large fruit size and good taste, it is recognized by consumers and widely cultivated. In the north, single-wall hedge cultivation is mostly used, while in the south, there are flat scaffold cultivation, single-wall hedge cultivation, and T-shaped hedge cultivation. Japan is a relatively developed country for viticult...
