To control weed in tobacco field more effectively, field experiments were carried out with 3 types of herbicidal film after flue-cured tobacco transplanting. The results indicated that the control effects of green, black and Kingduer film after 40 days of film covering to monocotyledonous weed (fresh weight) were 90.6%, 97.2% and 56.0%, respectively, and to dicotyledonous weed (fresh weight) were 64.2%, 60.8% and 26.7%, respectively. The variance analysis showed that the difference between different treatments was extremely significant. 30 measurements in 10 days showed that, the average temperature of soil in the depth of 0 cm, 5 cm, 10 cm covering with black herbicidal, Kingduer, green herbicidal, and conventional films were 33.1° C, 28.8° C, 26.8° C, 24.7° C, respectively.
