Engineering Technology Development of Temperature and Lighting Control Promote Productivity of Chinese Solar GreenhouseLiu Wenke

In China，protected horticulture industry has developed rapidly in the past decades，ranking first worldwide and consisting of plastic-covered tunnel，Chinese solar greenhouse（CSG），multi-span greenhouse and plant factory.CSG is unique greenhouse form of China with advantages of low cost，easy management.However，CSG has disadvantages of low per unit yield，bad environmental control capacity，severe environmental pollution and frequently suffered to high & low aerial temperature stresses.Up to date，CSG can′t be used for year-round production.In fact，temperature and light inner CSG are two crucial environmental factors that determine cultivation patterns and its productivity as well as year-round production ability and environmental impacts.So，to develop temperature and lighting control technology and equipment is key way to improve the productivity for CSG.Currently，some promising technologies were put forward for temperature and lighting control in CSG.Some novel technology progresses were collected and highlighted.
