Abstract: To identify the optimum number and period of removing the field inapplicability and fresh leaves, the variance analysis and comprehensiveevaluation way of orthogonal experiment design were employed to study the influence of different numbers and periods of removing the field inapplicability and fresh leaves on chemical components of upper flue-cured tobacco. The results showed that the number of removing the lower leaves was the key factortochemical components of flue-cured tobacco. The bestmodel of structure optimization of flue-cured tobacco in Shaoyang was removing 2 lower tobacco leaves at the time oftobacco topping and removing 1 top tobacco leaves at the time of the first roast from the bottom.The number and period of removing the inapplicability and fresh leaf in field affected chemical components of upper flue-cured tobacco.
