Cultivation techniques of grape for shelter from rain

Grape is a very common fruit in our daily life, and now the planting area of grape in our country is very large. Grape cultivation also has more cultivation patterns. Rain shelter cultivation is one of them, rain shelter cultivation can effectively reduce the incidence of diseases and insect pests and improve the planting efficiency of grapes. So how to protect the grapes from the rain? The following editor brings you the cultivation techniques of grape shelter from the rain, let's have a look!

1. Prepare the shelves for shelter from rain

Grape shelves for shelter come in many forms. Among them, the commonly used is hedge planting. First of all, a crossbar of about 150 cm long should be fixed at the top of the grape rack. The material of the crossbar is not limited, but it is best to use steel, because the firmness of steel is the best. Then erect a pole about 40cm high up in the middle of the crossbar. Then build an arched frame at both ends of the crossbar and fix it with the bar of the hedge. Then wire is used to connect the adjacent arches to form a wire frame. Cover with another layer of plastic film to protect against rain.

2. Film mulching selection

The time of plastic film mulching for rain shelter cultivation should be carried out when the temperature is higher in summer. Therefore, the choice of coating is very important, to be sun-resistant, not easy to crack aging PVC film, to ensure that the film has a strong resistance to high temperature, strong permeability. In general, the service life of the film can reach about two years. In order to achieve the normal growth and development of grape branches, the rain-proof film should maintain a space of about 25 centimeters between the branches and leaves. Then the width of the membrane is determined according to the width of the arch surface. In order to ensure that the rain shelter is strong enough, it should be fixed with laminating thread or nylon rope after covering the film.

3. Mulching time

In shelter cultivation, if the cultivation area is small, or if it is planted at home, then the film should be covered before it rains. Then the film can be removed after the weather clears up. If it is planted on a large scale, it should be covered with plastic film before the rainy season according to local climate change and weather conditions. In the south, the flowering period of grapes is usually cloudy and rainy. Therefore, we should pay attention to do a good job of covering the film before the grape blossoms, and then remove the film until the grapes are harvested and the branches are fully ripe.

4. Daily management

In the cultivation of shelter from the rain, soil drought is easy to occur because the roots of grape plants are less likely to receive natural water. When the soil is too dry, we should pay attention to timely watering, especially when the young fruit is growing, we must ensure that there is sufficient water. When covered, the microclimate in the canopy layer will change and is prone to diseases and insect pests. Therefore, we should pay attention to do a good job of summer cutting to avoid canopy closure leading to diseases and insect pests. Then when the temperature exceeds 33 degrees, pay attention to the timely release of the film to cool down.

The above is a brief introduction to the cultivation techniques of grape shelter from rain. That's all for today's introduction. This article is for reference only. I hope it can help you all.
