Everyone knows that multi-span greenhouses are generally built from unstable materials such as glass, and they cannot withstand much gravity. Especially during the snowy winter season, how to remove snow from the greenhouses has become a serious problem that must be faced in winter.
Reasonably select the basic snow pressure for greenhouse design. For areas prone to snow disasters, the current design snow load for plastic greenhouses is usually considered as 30 years, for glass greenhouses as 50 years, and for solar greenhouses and plastic greenhouses as at least 20 years. For mountainous and partially snowy areas, snow load assessment should be carried out according to specific terrain conditions during the construction of greenhouses, in order to obtain a more reliable design snow load and ensure high safety and reliability of greenhouse construction under economic conditions.
Whether the snow is too thick or the insulation blanket is opened, it will directly affect the light transmittance inside the greenhouse. For some light loving plants, it is necessary to take some necessary light supplement measures, such as turning on the light supplement lamp.
