At present, many rural areas in China have adopted the cultivation mode of greenhouse vegetables. This is irrelevant to the benefits brought by greenhouse vegetables. However, greenhouse vegetables are not enough to comfort the winter. What should the greenhouse vegetables do in winter? Let's learn about the main points of winter greenhouse vegetable prevention.

First, the stable greenhouse

When it snows, if there is snow on the top of the shed, if the shed is not stable, it is easy to be crushed by snow at the top. Therefore, after the winter comes, check the connection of the shed and tighten the film line of the shed. Avoid the more leaky places in the greenhouse, the more permeable, the more likely it is to go wrong. Secondly, it is possible to replace the shed film. Nowadays, the development of agricultural science and technology is good, and various shed films have emerged. Vegetable farmers can purchase the best translucent shed film to increase the light-increasing temperature.

Second, multi-layer coverage

In the shed, a small arch shed is set up. If you think that the cost is too high, you can use the straw curtain or sack to cover the outside of the shed to maintain the insulation. Vegetable growers who grow solanaceous vegetables should pay attention to it. Solanaceae vegetables are very afraid of low temperature, so it is necessary to strengthen insulation measures.

Third, look at the weather forecast

Looking at the weather forecast for fifteen days, the current weather forecast is more accurate. Even when there are rain or heavy snow, the weather will be forecasted. If you pay attention to the weather, you can prepare in advance.

Fourth, matters needing attention

The problem to be aware of is that the sooner you need to add a small arch shed and cover the straw, the better, don't wait for the snow to come and cover it again. It will not help in advance. The early cover can store heat in advance, so that the temperature in the shed can be maintained. In a constant state, it also allows the sudden cold air to have less impact on greenhouse vegetables.

After the rain and snow, it is necessary to clear the snow outside the greenhouse in time, do not let the snow cover the roof, affect the greenhouse vegetables to receive the sunlight, the snow should not be stacked around the greenhouse after the removal, avoiding the snow to water the vegetables in the shed Cold water reduces surface temperature. The above is the specific measures for all greenhouse vegetables to prevent freezing damage after the winter, and hope to help the farmers.
