Abstract

The invention discloses a method for preventing outdoor seedless cultivated Kyoho grapes from cracking. The method comprises the steps of carrying out spike shaping during an initial flowering stage; carrying out seedless treatment during a full-bloom stage; immersing fruit clusters in gibberellic acid in 10-15 days after the full-bloom stage and carrying out expansion treatment on the fruit clusters by adding forchlorfenuron in the gibberellic acid; then fixing the fruit clusters and timely carrying out fruit thinning; covering a white mulching film on the ground after grapes are bagged, wherein relatively stable water in a grapery is ensured, fruits can gradually grow bigger and bigger, and grape fruits can be prevented from cracking. According to the method disclosed by the invention, through standard management such as spike shaping, fruit cluster fixing, fruit thinning, bagging by dedicated grape bags and shoot pinching, the adnation of fruits is uniform, the fruit clusters are gorgeous in appearance, the grape yield is stabilized, and the grape quality is increased.

Description

A kind of method of preventing and treating open country seedless cultivation kyoto grape dehiscent fruit

Technical field

The invention belongs to wine-growing field, particularly relate to a kind of method of preventing and treating open country seedless cultivation kyoto grape dehiscent fruit.

Background technology

The main cultivation grape variety of Ju Fengshi China, but there is the heavy problem of fruit drop in the huge peak of outdoor cropping, if open country adopts seedless cultivation, huge peak can be made without seed, fringe shape is attractive in appearance, and mouthfeel is good, but due to huge peak fruit expanding period, at a time when the mould Pluvial, rainfall is large, and moisture change in vineyard greatly, causes seedless cultivation huge peak fruit grain dehiscent fruit, destroy fringe shape, cause the underproduction.The seedless cultivation method of existing kyoto grape, easily causes the serious dehiscent fruit of fruit grain, and fruit grain dehiscent fruit incidence reaches 25 percent, and dehiscent fruit causes grape Severe Reduction, every per mu yield about 750 kilograms, and fruit grain raw uneven, and the exterior quality of grape is poor.

Summary of the invention

In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of method of preventing and treating open country seedless cultivation kyoto grape dehiscent fruit.

For achieving the above object, the present invention is achieved by the following technical solutions.

Prevent and treat a method for open country seedless cultivation kyoto grape dehiscent fruit, comprise the following steps:

1) within 7 days before kyoto grape is bloomed, to initial bloom stage, carry out spending fringe shaping, dredge the secondary fringe of fringe of deflorating and topmost some stalk little Hua fringe, stalk little Hua fringe is propped up in reservation Hua Sui bottom;

2) to flower fringe leaching gibberellic acid seedlessness processing when grape is absolutely bloomed, interval 10-15 days, CPPU is added to fruit ear leaching gibberellic acid and expands process, the young sprout of each root growth golden mean of the Confucian school is selected and remain, and a fringe is beared fruit evenly, fruit grain size is basically identical, the good fruit ear of fruit ear fringe type, all the other fruit ears are removed, by controlling vintage, ensureing grape quality, making high-quality grapes fruit rate reach more than 90%;

3) determine fruit ear to terminate, carry out fruit thinning grain in time, fruit grain raw evenly has growing space, the seedless kyoto grape of production high-quality between fruit grain, each Ear-Weight with 450 grams to 500 grams for standard;

4) after fruit thinning burl bundle, timely spraying low toxicity highly effective pesticide, cover grape bag special; Before cover grape bag special, spraying low toxicity highly effective pesticide, object is that minimizing grape fruit ear is susceptible.

5) after grape bagging, covered ground white mulch film; Covered ground white mulch film, can reduce moisture and sharply change, soil moisture is kept in balance, reduce dehiscent fruit.White mulch film is reflective, accelerates grape painted, 6 days painted morning of grape, and improve grape degree of staining, painted atropurpureus fruit ear reaches more than 90%.

6) after grape germinates, time young sprout grows to 12 blades, carry out first time pinching, make top sublateral shoot continued growth after pinching, the pinching of regrowth 5 leaf, after pinching, make top sublateral shoot continued growth again, the pinching of regrowth 5 leaf, other sublateral shoot stays 2 leaf pinching, and by even for grape young sprout colligation on frame face;

7) gather after grape maturity.

The method is cultivated by grape kernal eliminating, and after grape bagging, covered ground white mulch film, makes vineyard moisture comparatively stable, and fruit grain expands gradually, control grape fruit generation dehiscent fruit.The method by flower fringe shaping, determine fringe and dredge grain, standardized management such as cover grape bag special and Tipping etc., fruit grain raw even, fruit ear outward appearance is gorgeous, stabilizes vintage, improves grape quality.

Beneficial effect: compared with prior art, the invention has the advantages that: the generation significantly reducing fruit grain dehiscent fruit, fruit grain dehiscent fruit incidence controls below one of percentage, and fruit grain evenly raw, fruit ear outward appearance is gorgeous, ensure that the exterior quality of grape, high-quality grapes per mu yield can be improved, every per mu yield about 1,000 kilograms.
