Abstract
The invention discloses a regulating system and method for multilayer shading film of plastic greenhouse with adjustable shading rate. The upper film of the sunshade is a fully transparent film, while the middle film and the lower film are printed with dots, which are interlaced. Through the measurement and comparison of the warm light in the greenhouse, the combined control of the sunshade film is realized. Not only can it adjust its light blocking rate, but it also has a heat insulating effect when there is a certain amount of air in the film.
