| Abstract: |
| 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. |
