为解决湖南烟区冬季大棚育苗常遇到的低温寡照问题,以云烟87为试验材料,利用自制不同波段的荧光粉组装成不同光谱的LED植物光源器件,开展不同光质LED对苗期的补光试验,研究LED不同光质对烟草育苗及烟苗生长的主要生理指标的影响,同时采用荧光灯进行对照试验。结果表明,采用LED补光,烟苗出苗率、苗高、茎围、最大叶长、最大叶宽、茎高、叶绿素、根系活力较荧光灯(对照组)显著增加。最佳LED补光可以缩短育苗时间至47 d,较对照组提前36 d,显著增强了成苗素质。在荧光粉激发型LED植物光源器件中,以发射峰位于630 nm波段荧光粉的器件补光效果最好,其所育烟苗素质较对照组高,能达到移栽壮苗要求,可以满...

In order to solve the relative low temperature and low-light supply problems in human tobacco greenhouse areain winter, this study employed Yunyan 87 as the test material, and several self-made various spectral bands emittingphosphors have been fabricated into a series of phosphors-converted light emitting diodes （ pc-LEDs ） devices.Furthermore, the effect of different LEDs light quality supplements on main physiological indexes of tobacco seedling hasbeen studied in detail. Meanwhile, fluorescent lamps were employed to conduct contrast exper...
