Pollution-free cultivation method for Kyoho grape

Abstract

The invention relates to the technical field of grape cultivation and specifically provides a pollution-free cultivation method for Kyoho grape. The method comprises the following steps: cutting grape spike tips before blooming, removing subsidiary spikes and overlong spikelets on upper grape branches and applying a proper amount of fertilizer per mu; beginning bud picking when winter buds in main grape vines germinate to about 2 cm; carrying out tertiary branch selection for grape trees when new shoots grow to 4 to 5 leaves; carrying out grape thinning and grape cluster management before grape berry enlarges; after the grape cluster management, dipping grape clusters into broad spectrum insecticide and bactericide; and then carrying out air drying and carrying out bagging with special paper bags. The grape cultivated by using the cultivation method provided by the invention has the following advantages: rain resistance is obtained; grape cracking is alleviated; propagation of disease and pest damage is prevented; coloring of the grape clusters is uniform; grape surface is clean; grape powder is integral; grape bearing rate and output are enhanced; weight of the grape clusters is increased; the grape clusters are neat and have large sizes; mature period is advanced; total usage amount of the insecticide and bactericide is reduced by more than 30% during cultivation; and grape berry can meet the requirement for no toxicity and harm.

Description

technical field [0001] The invention relates to the technical field of viticulture, and specifically designs a pollution-free cultivation method for Kyoho grapes. Background technique [0002] Kyoho grape is a tetraploid variety that was successfully bred by hybridization technology in Japan in 1937. It inherited the excellent quality of the male parent’s extra large grains, although it also inherited the shortcomings of the male parent’s severe drop of flowers and grains, resulting in a yield after 2-3 years The quality of fruit and fruit gradually decreases, and the phenomenon of large and small grains is serious. Botrytis and downy mildew are prone to occur in the early stage, and grain shattering and large and small grains are serious. During the ripening period, it is rainy, causing a large number of fruit cracks and sour rot. Severe, it is easy to cause heavy losses to growers . Contents of the invention [0003] In order to solve the problems in the prior art, th...

Problems solved by technology

[0002] Kyoho grape is a tetraploid variety successfully bred by hybridization technology in Japan in 1937. The serious shortcomings of falling flowers and grains, as a result, the yield and fruit quality gradually decrease after 2-3 years. A large number of fruit cracks, acid rot occurs seriously, and it is easy to cause heavy losses to growers
