Study On Ecological Effect In Different Structure Heliogreenhouse

Three heliogreenhouses of different structure were selected as measure and test material of my dissertation in the DaTai village % suburban of the Huhhot. The light intensity ^ temperature include air temperature and soil temperature inside heliogreenhouse % air humidity were serially observed, and computing of the growing tendency % yield % contamination on cucumber, ecological analysis on thrifty heliogreenhouse in latitude 40?9' area. At the same time, solar utilization ratio* economic benefits and structure of the three heliogreenhouses of different structure were analyzed. The results showed that ecological effect of II type heliogreenhouse. Go step further analysis showed, the structure of II type heliogreenhouse is better for the region of Huhhot, further, there is a reasonable solving way on the questions of lower temperature and faint light in the earlier spring % later Autumn and all the winter of the northern heliogreenhouse of China, Directing produce of heliogreenhouse. There is a directing significance on heliogreenhouse construction in the desertification...
