Use and maintenance of greenhouse snow greenhouses 1. In snowy weather, special personnel must be arranged to patrol, close the external shading system and close the sunroof. Manually and timely clean up the snow on the top of the greenhouse to minimize the accumulation of snow to reduce structural pressure; always pay attention to the snow on both sides of the gutter and in the gutter. When removing snow, do not use sharps to avoid scratching the covering material; snow removal personnel should walk along the gutter, and it is strictly forbidden to directly step on the top covering material.
2. The greenhouse with heating equipment should increase the heating in the snowy weather. If necessary, the inner insulation curtain can be opened to quickly increase the temperature inside the greenhouse and accelerate the melting speed of the lowest layer of the top snow;
3. In snowy weather, non-heating greenhouses need to use temporary heating equipment, such as hot air blowers, hot air stoves, or any other measures that can be used to enhance the temperature in the greenhouse;
4. While clearing the snow on the roof, be sure to pay attention to the cleaning of the snow on the opposite side, and do not form excessive side pressure;
5. If the snow is too thick, it will directly affect the light transmittance in the greenhouse. For some hi-light plants, it is necessary to take some necessary light-filling measures, such as turning on the fill light;
6, due to the special nature of the snow, it is likely to cause temperature and humidity in the greenhouse:://news.chinawj.com.cn
