Improved sunlight greenhouse thermal storage function

The sunlight greenhouse is a good favor to farmers in northern area of China. However, in a long time the inner greenhouse temperature adjustment is a big technology problem. Recently, Chinese Academy of Agricultural Sciences team has solved this problem. Their research achievement was named as the key technology research and application of thermal storage and exothermal of sunlight greenhouse. It was the first time to come up with the active exothermal theology and method all around the world which has changed the traditional passive thermal storage method.
The traditional sunlight greenhouse frequently had chilling injury in the winter nights. To increase the greenhouse temperature, many farmers were blindly to thicken the walls even to 6m to 8m which wasted much land sources. It was reported that this research achievement has been applied to northeast, northwest and north China areas which has increased the lowest temperature for 5 to 6 degrees in winter, and has promoted the harvest time for 15 days to 20 days. And the cost was reduced and rate of earth usage was improved.
