Effect of Spectrum Conversion Film on Temperature,Light and Growth of Chinese Cabbage

Wang Yuxia Xu Kun Mi Qinghua (College of Horticulture Science and Engineering,Shandong Agricultural University,Tai'an 271018)  
The result of the experiment indicated that spectrum conversion film had higher light transmittance charac- ter and increased temperature in tunnel remarkably,as compared with common film(CK);the spectrum conversion film, when temperature was low,could enhance the air temperature and 5 cm deep soil temperature in tunnel by 0.5~0.9℃and 0.7~1.3℃respectively,but when temperature was high,it could decreased those by 0.2~1.0℃and 0.2~0.6℃respectively.So spectrum conversion film remarkably increased yield and improved quality of Chinese cabbage.The yield under spectrum conversion filmⅠandⅡincreased 7.53 % and 13.70 % respectively as compared with CK.
