通过对烟草植株覆盖红、黄、蓝滤膜获得红、黄和蓝光.研究了3种光质对云烟87生长及品质的影响.结果表明:①红光促进烤烟的生长,使株高和茎围增加,而黄光对烤烟的生长有抑制作用,使株高和茎围低于对照.②3种光质处理能使烤烟叶片最大叶长和最大叶宽增加,在处理的各个时间段,红光处理下的烟叶最大叶宽最宽,说明3种光质处理对叶片的形态有影响.③3种光质处理能使烤烟叶片数减少,在处理的15,45和60d,黄光处理的烟叶叶片数最少,显著少于对照.④3种光质下的烟叶氮、氯、钾质量分数以及钾氯比均高于对照.⑤黄光处理能降低烟碱的质量分数,红光和蓝光处理使烟碱质量分数增加.⑥化学协调性评价分值结果表明,黄光和红光处理的烟叶属于较协调,蓝光处理和对照的属于协调.
Red, yellow and blue light were obtained by covering tobacco plants with red, yellow and blue filters.The effects of three light qualities on the growth and quality of Yunyan 87 were studied.The results showed that: ① Red light promoted the growth of flue-cured tobacco, While the yellow light has an inhibitory effect on the growth of flue-cured tobacco, which makes the plant height and stem circumference lower than the control.③The three kinds of light quality treatments can increase the maximum leaf length and the maximum leaf width of flue-cured tobacco leaves, and at each treatment period, red The widest leaf width under the light treatment indicated that the three light quality treatments had an impact on the morphology of the leaves.③Three kinds of light quality treatments could reduce the number of leaves in the flue-cured tobacco leaves. At 15, 45 and 60 days after treatment, Leaf number was the least, significantly less than the control.④The nitrogen, chlorine, potassium and potassium to chlorine ratio were higher than the control under the three kinds of light quality.⑤The yellowing treatment could reduce the nicotine mass fraction, the red light and the blue light Nicotine quality scores increased.⑥Chemical coordination evaluation score results show that the yellow and red treated tobacco are more coordinated, blue light treatment and control belong to the coordination.
