光转换膜技术对叶菜产量的影响

Effects of light-conversion film on leaf vegetables yield

针对芥菜、白菜、菜心3种叶菜的9个品种,通过自然地栽培、空白膜栽培和光转换技术膜栽培3种模式,初步探索了不同膜栽培模式下的叶菜生长和发育状况。结果表明,3种蔬菜9个品种的地上部分鲜重均一致表现出光转换技术膜栽培模式〉空白（透明）膜栽培〉自然地栽培的趋势,不同品种间的地上部生物量在不同栽培模式下的增幅不同。与空白膜栽培模式相比,在光转换膜栽培模式下芥菜、白菜与菜心3种蔬菜不同品种间的地上部生物量增幅分别为20.53%~23.40%、20.13%~32.62%、16.43%~20.30%。与自然地栽培模式相比,在光转换膜栽培模式下芥菜、白菜与菜心3种蔬菜不同品种间的增幅分别为54.91%~67.08%、70.05%~101.52%、53.15%~136.85%。

This study focused on nine varieties of three leafy vegetables,including mustard,Chinese cabbage and flowering vegetables,through natural filed cultivation without film and conventional transparent film,as well as light-conversion film,three patterns to detect their influences on growth and development of different leafy vegetables. Results showed that all tested leafy vegetables growned best with highest fresh shoot weight under light- conversion technology film,followed by conventional transparent film,then naturally filed ithout film. The differences of fresh weight between three cultivation modes were differed with varieties. Generally,the fresh weight of mustard,Chinese cabbage and flowering cabbage under the light conversion film were 20.53%-23.40%,20.13%-32.62% and 16.43%-20.30% higher than vegetables cultivated in conventional transparent film mode,and 54.91%-67.08%,70.05%-101.52%,53.15%-136.85% higher than corresponding vegetables without film cover.
