When the weather turns cold, the first reaction of many people is to wear more clothes. In fact, crops are the same. The first way to keep warm is to hang straw curtains on the greenhouse and cover with straw thatches and quilts. And it is low cost and easy to manage. When the weather is hot, it can be removed appropriately. 2. Irrigation in the greenhouse Every winter, some growers will irrigate in the greenhouse. Some people may want to say, isn't this water cooling? By then, it will get colder and colder in the greenhouse. In fact, it is not. The temperature in winter is low. After irrigation, the soil will be isolated from the outside world. This water layer can play the role of cold insulation and heat preservation. The main reason is the temperature difference. If the temperature drops suddenly, it can give the greenhouse a chance to slow down .

3. Place light bulbs When the cold wave comes, in addition to cooling, there is not enough light. At this time, people often choose to use light bulbs to fill in the light. However, it must be noted that bulbs cannot be bought casually, and professional fill lights and incandescent lamps should be selected. About 60~100 watts is the best, so as not to burn crops due to high temperature. 4. Place the stove In the past, many people used stoves to heat their homes in winter. In fact, greenhouses can also use this method. However, when people enter the greenhouse, they should be ventilated first to avoid poisoning caused by too much carbon dioxide.
