1. The application of sunshade nets such as non-woven fabrics strengthens the role of both seedling and cultivation in autumn.
2. The sunlight intensity in the shed is significantly reduced. The greater the density, the better the shading effect. The black shading effect of roughly the same specification is better than the silver-gray shading effect.
3. The shading rate of general black is 42% (65%), and the shading rate of silver gray is 30% (42%).
4. The greenhouse temperature is reduced although the shading network is covered, more importantly, the surface is ploughed at 10 am with a large cooling rate.
5. High temperature inclination angle] flowing down the c surface, for example, the plant surface is at ambient temperature ℃, and the soil temperature between the two is ℃, which is suitable for the growth of crops.
6. Evaporation needs to be reduced in the shed, the soil moisture content is higher than that of the open field, and the topsoil is moist.
