摘　　要：以K326为材料,采用随机区组试验,研究了追施不同水平氨基酸水溶性肥料对烟株生长发育及旺长期烟草花叶病害的影响。结果表明:追施氨基酸水溶性肥的3个试验组烤烟生育期较对照组平均延长7 d,旺长期较对照组延长4～8 d;处理组在株高、节距、茎围及有效叶数等方面均优于对照组,且以T1(在当地追肥用量的100%基础上,追施3次氨基酸水溶肥)处理效果最为明显;T1、T2(在当地追肥用量50%基础上,追施3次氨基酸水溶肥)处理组在烤烟旺长期可有效降低烟草花叶病的发生率。The effect that water - solubled amino acid fertilizers had on the growth and development of tobacco as well as the tobacco mosaic disease at the stage of rapid shoot growth have been researched by randomized experiments on the materials of K326. The results suggested that the use of this fertilizer would prolong the growth season （ average 7 d） and vigorous growth time （ average 4 - 8 d）. Besides, it also improve agronomic characters of tobacco, T1 treatment （ fertilization water - solubled amino acid fertilizers three times base on the local fertilizer levels ） effect is most obvious. Morever, T1 and T2 （ fertilization water - solubled amino acid fertilizers three times base on the 50% local fertilizer levels ） would have an significant effect on controlling the tobacco mosaic disease at the stage of rapid shoot growth, which could effectively reduce the occurrence of pest and disease and inhibit its spread to some extent.
