不同人工光源下烤烟育苗研究

Study of Flue-cured Tobacco Seedlings in Different Artificial Light Source

[目的]分析不同人工光源补光对烤烟成苗品质的影响,筛选出适宜烤烟立体育苗生长的人工光源。[方法]设置5个不同光照条件下烤烟幼苗栽培试验区,分别为目前大多数用的普通荧光灯及研究较少的LED光源,对成苗生理生态指标进行数据统计和分析。[结果]与荧光灯区域相比,LED灯的补光区域烟苗光合作用增强,生长旺盛,干物质积累多,并且采用LED灯的红光和蓝光为光源补光,不但能促进烟苗的横向生长,还能有效地培育出高茎壮苗,其中红蓝LED灯设置光照强度为150μmol/(m2·s)时,成苗品质最好。[结论]该研究可为烤烟育苗人工补光提供数据支持和理论借鉴。

[Objective]The aim was to analyze the impact of different artificial light source on flue-cured tobacco seedling quality,and to screen out the suitable artificial light source for flue-cured tobacco three-dimensional seedling.[Method]Five cultivation test area of different light conditions that the light source was ordinary fluorescent lamp most used at present and LED lamp researched less resp.,and then the seedlings physiological and ecological indices were analyzed statistically.[Result]Comparing with fluorescent lamp region,LED lamp light increased the photosynthesis of seedlings,so the seedlings grew vigorously and dry matter accumulated more,otherwise,because the red and blue light of LED lamp were the fill-in light,they not only promoted flue-cured tobacco lateral growth,but also cultivated strong seedlings with high stem effectively,thereinto,when the designed red and blue LED lamp illumination intensity was 150 μmol/（m2 · s）,the seedlings quality was the best.[Conclusion]The study provides a data support and theoretical reference for artificial fill-in light during flue-cured seedling.
