| Abstract: | 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. |
