培育壮苗是优质烤烟生产的重要保证,中国当前普遍采用的烟草漂浮育苗技术存在诸多弊端,为对其进行改进,以‘湘烟3号’为材料,研究了移栽前控水与生根粉处理对烤烟烟苗素质和还苗期生理特性的影响。结果表明：（1）控水处理对烟苗素质影响较小,生根粉处理与控水＋生根粉处理对烟苗素质有显著影响,主要表现为株高下降、茎秆变粗、物质积累量增加。（2）移栽前控水与生根粉处理均可提高烟苗叶绿素含量与根系活力,以控水＋生根粉处理效果最优,生根粉处理次之,控水处理最差。（3）各处理均可提高烟苗硝酸还原酶与转化酶活性,降低烟苗丙二醛含量,效果以控水＋生根粉处理最好,生根粉处理效果次之,控水处...

Cultivating strong seedlings is an important guarantee for the production of high-quality tobaccoleaves, while there are many disadvantages in tobacco floating system that was commonly adopted in China. Toimprove the tobacco floating system,‘Xiangyan No.3＇was used as material, the effects of water control beforetransplanting and rooting powder treatments on tobacco seedling quality and physiological properties at greenstage were studied. The results showed that：（1） the effect of water control on tobacco seedling quality was little,while th...
