摘要
通过不同颜色聚氯乙烯薄膜大棚对比实验,研究了光质(光谱)对作物和蔬菜生长发育、产量、品质及发病率的影响。黄色聚氯乙烯薄膜大棚内黄瓜发病率和发病指数比对照降低36.7％和0.048,产量提高8.2％。
Through contrast experements in greenhouse with different color film covers,effects of light quality (spectrum) on growth,development,yield ,quality and disease of crop and vegetable are researched.
