摘　　要：采用不同颜色聚乙烯薄膜(无色膜、紫色膜、蓝色膜和红色膜)覆盖拱棚,分析探讨不同光环境对茄子幼苗品质的影响,以期为茄子育苗专用膜的研究及开发提供理论依据。结果表明,红色膜处理下茄子幼苗茎粗、全株干物质量及根系活力均较高,蓝色膜下最低。除小红袍(XP)幼苗株高以紫色膜处理高于红色膜外,其余品种均以红色膜下较高,蓝色膜下各品种幼苗株高均最低。不同颜色棚膜处理下,各品种茄子幼苗叶片中叶绿素a、叶绿素b含量均以蓝色膜下较高,红色膜下较低。从壮苗指数来看,红色膜处理的茄子幼苗较健壮,蓝色膜下长势较弱。综上可知,红色膜处理有利于培育壮苗,故可作为茄子育苗专用膜。Effects of different light conditions on the quality of eggplant seedlings were studied using different color polyethylene films （colorless, red, purple and blue） in order to find the best color films suitable for cultivating robust seedlings and to provide a theoretical basis for research and development of dedicated film of eggplant seedlings. The results showed that the stem diameter, total dry mass and root activity of eggplant seedlings were higher under the red film treatment, but the lowest under the blue film. Except Xiaohongpao （XP） treated with purple film was higher than red film, the other va- rieties plant height were the highest under red film and the lowest under blue film. The contents of chlorophyll a and chlorophyll b in leaves of all varieties were significantly higher under blue film treat- ment and lower under red film. The healthy index of eggplant seedlings treated with red film was sig- nificantly stronger, and the lowest with blue film. In conclusion, the red film contributes to healthy seedlings, so red film can be used for eggplant seedling-cultivating specific film.
