Abstract

Regular water requirement of flue\|cured tobacco at fast growing stage was studied. The results showed that the optimum relative water content was in a range of 75%-85% of the mass of soil, in which water\|utilization efficiency of tobacco plant was the highest, CO\-2 and moisture exchange between stomata of tobacco leaves and ambient air was the easiest, and the growth of root, stalk, and leaf of tobacco plant was the fastest.
