Effect of sectionally rolling heat preservation quilt on light and heat effect in solar greenhouse
In order to reduce the greenhouse heat loss,the Aksu area solar greenhouse as a research object,according to the actual situation in Xinjiang,the way of taking off the heat preservation quilt in sectional solar greenhouse was designed.By continuously observing the changes of light intensity and air temperature in the greenhouse,it is confirmed that the average temperature in the front and back of the greenhouse was increased by 0.6 and 0.8℃respectively by taking off the heat preservation cover of the segmented solar greenhouse compared with the way of taking off the heat preservation cover all at one time.In the daytime,the temperature in the greenhouse increased faster and decreased slower.The light intensity in the rear part of the greenhouse can be increased in a typical cloudy day;Therefore,the sectional rolling heat preservation quilt can effectively improve the performance of the sunlight greenhouse in Xinjiang and enhance the heat preservation and heat storage capacity of the greenhouse.
