In order to recycle the straw of flue-cured tobacco and find new fuel of flue curing which might substitute for coal,the straw was dried and crushed into blocks after tobacco leaves harvest for fuel of flue curing using the straw briquetting machine,and tests of flue curing replacing coal were carried out. The results showed that the flue curing curve of the straw briquetting was largely in line with that of coal,and it could satisfy the needs of flue curing,the grade qualities of tobacco leaves were equal to those by coal,and the straw briquetting consumption to coal was 1.64 ∶1. The cost of flue curing reduced by 189 yuan/hm2. So it was possible to use straw briquetting instead of coal in tobacco flue curing,and also significant to reduce environmental pollution and develop circular economy of tobacco.
