Near the New Year's Day, a new round of cold weather is about to hit. Many growers have begun to take warm measures for their own crops. In order to ensure that crops can survive the winter, what are the measures to keep warm and warm?

The first way to keep warm is to hang grass curtains on the shed, covered with grass rafts and quilts. And this is low cost and easy to manage. Some weather spots can be removed as appropriate.
Second, the shed water
Every winter, some growers will fill the greenhouse. Some people may have to say that this water is not cooling down? When the greenhouse is getting colder and colder. In fact, the winter temperature is low. After the water is poured, the soil will be isolated from the outside world. This water layer can play the role of cold insulation. It is mainly the temperature difference. If it suddenly cools down, it can give the greenhouse a chance to slow down. .
However, the way of watering should attract the attention of the growers, do not flood the water, and if the humidity of the shed is large, it is best not to use this method.
Third, place the bulb
When the cold wave comes, in addition to cooling, there is not enough light. At this time, people often choose to fill the light with a light bulb. But it must be noted that the bulb can not be bought casually, to choose professional fill light and incandescent lamp, 60~100 watts is the best, so as not to burn the crop plant too high temperature.
Fourth, place the stove
In the past, many people in the winter used stoves to warm their homes. In fact, greenhouses can also use this method. However, when people enter the greenhouse, they should first ventilate and avoid too much carbon dioxide to cause poisoning.
Fifth, the use of warming agent
There are many warming products on the market, and the voice of the warming agent has been very high. The role of the warming agent is mainly to produce nitrogen dioxide by fermentation, and then raise the temperature inside the shed. This method is also good, but must pay attention to ventilation.
