不同光质(光谱)对作物生长发育的影响

Effects of different light quality(spectrum) on crop growth and development

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%。

Abstract: 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.The spectra in yellow film cover greenhouse is better for cucumber.Its disease rate and disease index decrease 36.7% and 0.048,yield increases 8.2% compared with white film cover.
