Abstract: Using Yunnan cigar wrapper varieties Yunxue No.1 as material, nine kinds of topping periods and the number of leaves left were set up to study the effects of topping period and the number of leaves left on the agronomic and economic characters of cigar tobacco leaves. The results showed that Yunxue No.1 planted in Lujiang Town, Longyang District, Baoshan City, Yunnan Province, and Zhefang Town, Mangshi City, Yunnan Province, had better economic characteristics when the topping period was the same and the number of leaves left was 18. When the number of leaves left was the same, Yunxue No. 1 planted in Zhefang Town of Mangshi showed better economic traits when performing topping at the central flower opening 50%, while this variety planted in Lujiang Town showed better economic traits when performing topping at the central flower opening 10%. The interaction analysis showed that the number of leaves left had the greatest influence on the yield and output value of the cigar wrapper, followed by the topping period. The interaction between the topping period and the number of leaves left was minimal.
