Effects of different pore size of insect-proof net on microclimate environment of net room

In order to provide scientific evidence for vegetable production of insect-proof net, through the comparison of different pore size of insect-proof net the effects of microclimate environment of net room were studied. The results showed that the covering insect-proof net was beneficial to the microclimate environment generally. It could significantly decrease the light intensity, increased the air relative humidity, and relief the unfavorable influence of the strong light on the plant growth. The smaller pore size of insect-proof, the smaller light density and the larger air relative humidity. And the covering insect-proof net could increase air temperature and decreased ground temperature in clear day. Different pore size of insect-proof net had different influence on the microclimate environment in different weather, so we can choose suitable insect-proof net to satisfy our demand in vegetable production.
