不同光质处理对草莓生理特性的影响

摘要

以白光为对照,研究了LED红、蓝不同光质配比对草莓生长及生理特性的影响.结果表明,与对照相比,LED红光和以红光为主的光质配比明显促进生物量的积累,净光合速率以及叶片中可溶性糖含量增加.通过隶属函数分析,R7/B3光质配比的促进效果最突出,应选择R7/B3作为补光最佳光质组合.%With white light as the control,the effect of different LED red and blue light quality ratio on the growth and physiological characteristics of strawberry was studied.The results showed that compared with the control,the LED red and quality ratio dominated by the red light significantly promoted the accumulation of biomass,net photosynthetic rate and the soluble sugar content increase in leaves.Through the analysis of membership function,light quality ratio of R7/B3 had the best effect on the proportion of light quality,therefore R7/B3 could be chosen as the best quality ratio of supplementary light.
