Thermal insulation properties of active storage wall in the third generation solar greenhouse in Ningxia

In order to obtain a reasonable structure of wall in solar greenhouse，taking the normal solar greenhouse as contrast，we detected the air temperature，air humidity，soil temperature，sunlight intensity and heat storage capacity of the active storage wall in the third generation greenhouse. The results showed that，compared with the normal solar greenhouse，in the solar greenhouse with active storage wall，the average air temperature and ground temperature increased by 1.98℃ and 2.45℃，respectively，the insulation effect was obvious； the effective light intensity increased by 2.28 klx；but the humidity change was not obvious. The new structure of solar greenhouse in the heat preservation， light transmittance and other aspects were better than those in normal solar greenhouse，and had a strong frame and long life，etc，which had a good application prospect.
