How to manage the greenhouse in the snow?

In the past few days, with the advent of cold air, snow has been snowed in many places. The whole northern region has cooled down, snow has fallen, there has been no snow for a long time, and the weather is dry. It is just a heavy snowfall, which will relieve the crops and relieve the thirst. The drought is quite good. As the saying goes, "Ruixue Zhaofeng Year", some farmers have to be happy, and vegetables have to raise prices! However, some vegetable growers are crying, cooling down, snowing, causing freezing damage.

Xiao Wang is the first year to plant a tomato greenhouse in the village. Although it is the first year to plant a greenhouse, it is also the way to communicate with others. When I saw the weather forecast, there was heavy snow, and it was normal. It was normal to snow before. You are under your goose feathers. I am playing my mahjong. Now I am really anxious!

This is the first weather problem that I have encountered since I planted the greenhouse. Looking at the greenhouse where my wife had just poured water last week, the humidity is now very big. "The aging mothers of this defeated family don’t look at the weather forecast when they are watering," especially after snowing, covering the grass for a few days, in the shed. The humidity is particularly large, and the tomato disease will occur in a large area under the condition of high humidity. Xiao Wang is difficult to do it. In the end, the temperature is mainly based on dehumidification?

Xiao Wang found Zheng Laotou, who has great management experience in planting tomatoes in the same village. He explained the situation. Zheng Laotou said, “There is a big temperature drop and snow, and the tomato is easy to freeze. You must cover the grass to warm the greenhouse. You don't know that this tomato has reached 3 spikes now. At this time, the temperature is most needed to color the fruit! If the temperature in the shed is less than 25 degrees during the day, even the fruit is a problem! Is this humidity? I will say it after the weather.

The advice given by the technicians in the village is that on the one hand, the temperature increasing block can be used, the temperature in the shed can be quickly increased, the temperature is faster than that of the grass cover, and the height is 3-5 degrees; on the other hand, a plastic film is laid between the rows in the shed. Then sprinkle with quicklime, which is an exothermic process during the water absorption process. Moreover, the larger the amount, the better the dehumidification effect.

The question about the big shed in the snowy days is here. If your greenhouse is now experiencing heavy cooling and heavy snow, how do you do it? Is it warming first or dehumidifying first? Please leave a message in the comments section.
