Meanwhile, the heat preservation quilt is not in direct contact with the greenhouse covering material, so that the light transmittance and the service life of the greenhouse covering material are increased
4. Because the heat preservation is put on the ground, the overall height of the greenhouse is reduced, the north-south distance between the two greenhouses is reduced, and the land utilization rate is improved.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
