Prevention method for controlling vigorous growth of Kyoho grape

Abstract

The invention discloses a prevention method for controlling vigorous growth of Kyoho grape. The prevention method comprises the following steps of spraying 1.0-1.2 g / m<2> of chlormequat chloride of which the concentration is 700-900 mg / L or spraying 35-45 g / mu of 5% of liquid of uniconazole wettable powder which is diluted by 600-800 times in weight percent in a week before blooming; and continuously spraying 25-35 g / mu of 40% of liquid of flusilazole missble oil which is diluted by 3000-4000 times in weight percent for 4-6 times at every 6-9 days during an inflorescence exposing period. According to the prevention method disclosed by the invention, excessive growth of the Kyoho grape and the problem of serious flower and fruit dropping caused by the excessive growth can be prevented mainly through a chemical control method and by simultaneously matching with the clipping of braches and roots, the inflorescence can be elongated, the fruit setting rate of the Kyoho grape can be effectively increased, the fruit quality can be improved, the production of grape which is cultivated through the method is increased by 40%, and 98% of grape fruits can reach to the standard of pollution-free food table grape (NY5086-2002) sensory requirements.

Description

technical field [0001] The invention relates to the field of grape growth, in particular to a method for controlling the growth of Kyoho grapes. Background technique [0002] Under the conditions of suitable temperature, light and moisture, the branches and vines of grapes can grow all year round, and can branch many times. Too much fertilizer and water or improper pruning will cause new shoots to grow excessively, which is not conducive to the growth and development of fruits. Among them, Kyoho grapes are growing vigorously. Applying more organic fertilizers during the growing season will help improve fruit quality, but excessive nitrogen fertilizers will easily cause excessive plant growth and flower and fruit drop, resulting in severe flower loss, low fruit set rate, and loose fruit ears. Therefore, controlling the vigorous growth of Kyoho grapes is a key factor in determining fruit quality. Contents of the invention [0003] Purpose of the invention: the purpose of t...
