摘要
在烤烟的不同生育期分别进行不同灌水处理，试验结果表明：团棵期相对持水量在65％～85％，旺长期、现蕾期、成熟期相对持水量在45％～75％最有利于叶片生长；土壤含水量越高，越有利于烟株的增高，但对根的生长不利；水分过多过少都不利于产量的形成。相对持水量团棵期在65％～75％、旺长和现蕾期在75％～85％、成熟期在35％-45％时叶绿素含量最高。
Flue -cured tobaccos were irrigated at different growth stage. The results showed that the soil moisture content of 65% -85% at rosette stage, 45%-75% at faster growing stage, bud stage and maturing stage was the best for the growth of tobacco, the more soil moisture, the higher plant, but disadvantage for roots. So over or less soil moisture content was not good for the formation of yield of flue -cured tobacco; the chlorophyll content was the highest when the soil moisture content was about 65% -75% at rosette stage, 75% -85% at faster growing stage and bud stage, 35% -45% at maturing stage.
