How can low temperature and extreme weather help vegetables?

Four kinds of extreme weather are coming, how to save protected vegetables? In fact, for vegetables in protected areas, we should pay attention to the weather in time, strengthen facilities, prepare snow removal tools, strengthen heat preservation, moderately fertilize, exercise at low temperature, control watering and prevent heat preservation. Cover the outside of the greenhouse, and the insulation quilt must be covered with plastic film to prevent the temperature from being too low. If the temperature is too low, these vegetables will freeze to death. In fact, low temperature, strong wind and snowfall have added many hidden dangers to the safe overwintering of vegetables, and protective measures should be taken in vegetable planting.

At the same time, we should prepare Yuba conversion lamp and electric heater, and automatically heat the fan. The most important purpose is to raise the temperature in the shed. If the temperature is too low, these vegetables will freeze to death, so some auxiliary heating materials should be added for temporary heating. For these farmers, vegetables are very important, which may be all their savings, so we must find ways to make these vegetables safe for the winter before the cold and snowy weather strikes. Silk, organic fertilizers, such as pig manure, cow dung and other thermal fertilizers, and fertilizers with appropriate trace elements are actually good for vegetables and can also prevent diseases. For these vegetables, measures must be taken to keep warm and cold. Only in this way can these vegetables thrive.

In fact, a lot of preparations have to be made before the cold wave comes. We must avoid insufficient nutrition supply, improve the cold resistance of vegetables, and reduce the occurrence of rotten vegetables and frozen vegetables. At the same time, open vegetables should be cleaned in time to prevent water accumulation in the field. In fact, greenhouse vegetables must pay special attention, because many vegetables are particularly vulnerable to freezing and frostbite, which will also have a certain impact on the harvest. Because we want to sell the freshest vegetables better, these problems must be solved.
