Studies on technics for regulation of the eco-environment in plastic greenhouse
塑料温室生态环境调控技术的研究

The changes of temperature and humidity and their relations with light intensity in plastic greenhouse were studied. The results showed that the eco-environment of greenhouse can be improved,vegetable growth and development in winter and early sping can be increased,and pest and diseases can be controlled by artifically regulating the temperature,humidity and light conditions inside greenhouse.
