How to deal with the bad weather in the shed?

In the process of snowing, you can use the blower driven by portable gasoline engine to blow snow when conditions permit, and the effect is very good. Strong cold current cooling in the cold winter, it is inevitable that there will be cold current cooling weather, which will appear several times every winter. In the continuous sunny days, there is a strong cooling, because the greenhouse stores more heat, 1? There will be no frostbite for two days. If there is cold current and strong cooling after continuous cloudy days, it is easy to cause freezing injury. In this case, it is necessary to carry out artificial auxiliary heating at night, such as using a hot blast stove to ignite the heating block (3 am? 5 o'clock), put a warm water bag on the surgical line and light a candle on the front foot; You can also use "two curtains" to form a "shed in a shed", which is opened during the day and covered at night, and the effect is better. For greenhouses, straw mats can be erected on both sides. The heat energy of the shed comes entirely from the solar radiation of continuous cloudy days. In case of continuous cloudy days, the temperature in the shed is low. It is wrong for some vegetable farmers not to uncover the grass in the greenhouse to keep warm. Because there is also scattered light on cloudy days, or the sunshine irradiation time is short, the temperature in the greenhouse will rise to a certain extent, and crops can still carry out photosynthesis after receiving scattered light, generally reaching above the light compensation point.
