Some weather hot spots can be removed appropriately. Second, irrigation in the shed Every winter, some growers irrigate in the greenhouse. Some people may say, isn't the water cooling? By then, the greenhouses will get colder and colder. In fact, otherwise, the temperature is low in winter, and the soil will be isolated from the outside after irrigation. This water layer can serve as a thermal insulation, mainly due to the temperature difference. If the temperature suddenly drops, it can give the greenhouse a chance to slow down . However, the watering method should attract the attention of the growers, do not flood the water, and if the humidity in the shed is relatively high, it is best not to use this method. Third, place the bulb When the cold wave came, in addition to cooling, there was insufficient light. At this time, people often choose to fill the light with a bulb. However, it must be noted that bulbs cannot be bought at will, and professional fill lamps and incandescent lamps should be selected. About 60 to 100 watts are the best, so as not to burn the crop plants if the temperature is too high. 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, first ventilate it to avoid poisoning caused by too much carbon dioxide. Five, use a warming agent There are many warming products on the market, and the voice of warming agents has always been high. The role of the warming agent is mainly to produce nitrogen dioxide through fermentation, and then increase the temperature in the shed. This method is also good, but we must pay attention to ventilation. Disclaimer: Some articles on this website are transferred from the Internet.
