How to correctly manage greenhouse cherries in bad weather

Greenhouse cherry

In recent years, due to the high efficiency of cherries in greenhouse, the development area has increased rapidly. In the event of bad weather, fruit growers will suffer huge losses once they are mismanaged. In the process of management, attention should be paid to the following points:

First, the cold weather. If you encounter continuous low temperature in winter or early spring, grass mulch and other mulch should be uncovered properly and late in cold weather, and the change of greenhouse temperature should be observed after uncovering. If the shed temperature changes slightly, it should be covered with the cover to make the greenhouse temperature rise, and the cover should be re-covered before 2 o'clock in the afternoon. In order to increase the temperature of the shed at night, the thickness of the cover can be increased appropriately, or the furnace burning time can be increased. Remember not to uncover the mulch all day or even for several days in cold weather.

Second, windy weather. Fix the transparent cover during the day to avoid being blown away by the wind and press the grass at night. Once the mulch is blown off by the wind, cherries can easily freeze flowers or fruits, resulting in a reduction in yield.

There will be cloudy weather around noon. The temperature of the shed changes quickly when the light is strong around noon. If clouds appear in the air, the temperature of the shed should be observed at any time, and the temperature of the shed should be closed. After sunrise, the temperature of the shed will rise quickly, so the vents should be opened in time to prevent burns, especially after fruit setting.

Fourth, rain and snow. Cover the grass when it rains and snow during the day, cover it with a film to prevent rain and snow, and remove the accumulated rain and snow immediately after the rain and snow stops; when it snows at night, sweep the snow in time after the snow stops the next morning, keep the cover dry, and remove the cover so that the fruit trees can see the light. When it suddenly clears up after continuous snowfall, pay attention to the changes of cherry trees when removing the mulch to see if the new leaves are withered. Cover them with grass immediately when you find them, and then uncover them after recovery. If it is repeated for 2-3 days, it can be transferred to normal management.
