摘要
以烟草品种‘云烟87’为材料,研究了育苗大棚补充光照对‘云烟87’烟苗生长的影响。结果表明:在早晨及傍晚时,补充光照可使育苗棚内的光照强度显著提高;较强的光照强度能够提高烟苗的出苗率,缩短育苗期;在大十字期及成苗期,补充光照处理的烟苗茎高、茎粗、叶长、叶宽、SPAD和干物质总量均有提高。可见,适时适量的补充光照对‘云烟87’烟苗的生长具有积极的影响,可为优质烤烟生产奠定良好基础。
The effects of supplementary illumination in greenhouse on the growth of tobacco seedlings of‘Yunyan 87’were studied.The results showed that in the morning and evening,supplementary illumination could significantly increase the light intensity in greenhouse.Stronger light intensity could improve the emergence rate of tobacco seedlings and shorten the seedling-raising period.At the three to four leaves stage and seedling transplanting stage,the stem height,stem diameter,leaf length,leaf width,SPAD and total dry matter of tobacco seedlings treated with supplementary illumination increased.In summary,timely and appropriate supplementary illumination could have a positive impact on the growth of‘Yunyan 87’tobacco seedlings and lay a good foundation for the production of high-quality flue-cured tobacco.
