Cultivation method for preventing gas burning disease of grapes

Abstract

The invention provides a cultivation method for preventing the gas burning disease of grapes. The aim of increasing the leaf-fruit ratio of a tree body is achieved by processing young sprouts and auxiliary sprouts before the flowering period, the root environment is improved by covering black mulching film in real time after the flowering period, fruit faces are continuously sprayed with 0.2%-0.3% CaSO4 two to three times in the young fruit period to increase the tenacity of fruit peels, and the tree body is sprayed with 0.1% 1000-2000-fold abscisic acid, 0.2%-0.3%KH2PO4 and 0.5%aspirin before the fruits are sleeved with bags to strength the resistance of the tree body. A series of cultivation regulation measures are taken, so that nutrition distribution of the tree body and the external environment are improved, the stress resistance of the tree body is strengthened, and the fundamental aim of preventing the gas burning disease of the grapes is finally achieved.

Description

technical field [0001] The invention belongs to the field of grape cultivation, in particular to a cultivation method for preventing grape gasburn. Background technique [0002] Air scorching of grapes, also known as fruit shrinkage, is a physiological disease directly or indirectly related to special climatic conditions and cultivation techniques. It mainly harms fruits, and sometimes leaves also suffer from this disease. This disease is one of the manifestations of "physiological water imbalance". The disease is very common in thin-skinned varieties such as Xiahei, Meirenzhi, and Red Earth, especially after bagging. In recent years, with the frequent occurrence of abnormal weather, various degrees of gas burn occur every year in grape producing areas all over the country. In severe cases, the rate of diseased spikes is above 80%, and the loss is 20% to 60%. For bagged grapes, the ear thinning and fruit thinning work has been completed before bagging. If gas burn occurs a...

AI Technical Summary

Problems solved by technology

In 2011, nearly 5,500 acres of red earth grapes in Yumen, Gansu suddenly suffered from gas burn, and the incidence rate was as high as 80%, which seriously affected the grape production and the economic benefits of growers; Gas burn disease, and the condition is relatively serious. Only nearly 1,000 mu of summer black grapes in Wuxi area had gas burn disease, and the planting loss was about 50% in that year; the incidence rate of gas burn disease in Tangzhuang Village, Jurong, Jiangsu, was as high as 40%. , which was the most severe case of grapes planted in this area, and the fruit farmers suffered heavy losses

In terms of production, such diseases can only be prevented in advance, but how to effectively prevent the occurrence of gas burn in the vineyard field, there is still no systematic method found in various places. The main means are still around improving soil structure, controlling Yield, etc. Although these single technical means have certain effects in preventing grape gasburn, they have not really solved the problem.
