摘　　要：用盆栽试验方法,研究了土壤水分条件对烤烟干物质积累、根系活力和硝酸还原酶活性的影响。据此确定烤烟各生育时期适宜其生长发育的相对土壤含水量指标为:伸根期60%-68%;旺长期78.5%-81%;成熟期76%-78%。Based on some physiological indexes, the adequate soil moisture indexes of flue-cured tobacco growth were studied by potted plant tests. The results showed that the adequate index of relative soil moisture content were 60%-68%,78.5%-81% and 76%-78% in transplanting to bird nest stage , bird nest to topping stage and ripe stage, respectively.
