In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, appearance and heating conditions.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model monitors the light intensity in the greenhouse in real time by setting a light intensity sensor inside the greenhouse body. When the light intensity exceeds the preset threshold, the controller issues a command to start the drive motor, so that the screw rotates to drive the moving column to move forward with the guide rod, open the sunshade cloth for shading, and reduce the light intensity in the greenhouse; when the light intensity is lower than the preset threshold, the controller issues a command to start the winder to wind up the sunshade cloth, close the sunshade cloth, and increase the light intensity in the greenhouse.
