The grapes are sheltered from the rain and cultivated during the growing season of the grapes. They are covered with transparent plastic film over the grape seedlings. When it rains, the water flows along the membrane and is discharged outside the garden. It does not fall on leaf vines, fruit and gardens. Preserved grape cultivation mainly has the following advantages:
The benefits of grape shelter cultivation
The first is to effectively solve the problem of grape flower protection and increase the fruit setting rate. Under the condition of not using hormones, the vineyards sheltered from rain do not have natural conditions. The grapes are in good condition, which saves the cost of the medicine and is conducive to the pollution-free production of grapes.
The second is to reduce the soil moisture and air humidity in the garden, which is not conducive to the reproduction of pathogens, and can effectively reduce the occurrence and harm of blackpox, downy mildew, white rot, anthrax, and gray mold. In the rainy northern Guangxi region, the comparable incidence of grape disease is reduced by more than 85% in open field cultivation, thereby reducing the frequency of spraying and the amount of pesticides used, and improving the use of pesticides. It is not only conducive to the production of pollution-free grapes, but also can save pesticides, labor, and reduce production costs. Exposed cultivation requires 24 to 26 pesticides per year, and after rain cultivation, the number of medications is reduced to 6-8 times.
Third, it can reduce the types of diseases that the rainwater spreads, overcome the influence of unfavorable climatic factors, make the leaves and fruits complete, and extend the life of the leaves, thereby prolonging the harvest period of the grapes for 25-30 days so as to respond flexibly to market demands and improve production efficiency. .
The fourth is to adopt grapes that were produced by rain-fed cultivation. The number of pesticides was reduced, and the fruit surface of grapes was reduced. The fruit quality was greatly improved. Due to the improvement of quality and food safety level, it has obvious advantages in market competition. The Kyoho grape that has been sheltered from rain cultivation has increased its price per kilogram by more than 1.0 yuan per kilogram of cultivated land due to its improved quality, and increased revenue by about 2,000 yuan per mu.
Fifth, the fruit rate has greatly increased. Compared with the open-cultivated vineyards, the Kyoho grape, which has been sheltered from rain, will increase the fruit rate by about 30 percent, that is, about 500 kilograms per kilogram of harvested fruit, and will be calculated at 6 yuan per kilogram of purchase price per acre. An increase of 3,000 yuan.
Therefore, the implementation of shelter cultivation, the economic benefits of grapes are very significant.
