Abstract: To explore application of bast-fiber film in tobacco planting, a field trial was conducted with different films(bast-fiber film, no film and polythene film). The effects of bast-fiber film mulching on soil temperature, soil water content, flue-cured tobacco growth, tobacco leaf yield and quality were studied. The results showed that the soil average temperature of bast-fiber film mulching was less than that of polythene film mulching and more than that of no film mulching, and the soil temperature fluctuation of polythene film mulching was wild, but that of bast-fiber film mulching was small. The bast-fiber film mulching improved the soil water content. In early stage the tobacco growth with bast-fiber film mulching was worse than polythene film mulching, just the contrary in maturity. The tobacco leaf yield of bast-fiber film mulching increased by 6.5% and 11.3%, and the tobacco leaf output value increased by 11.0% and 25.3% compared with these of polythene film mulching and no film mulching, respectively. The rate of medium-superior tobacco of bast-fiber film mulching rised up 4.1 and 9.8 percentage points compared with these of polythene film mulching and no film mulching. There were higher potassium concentration, lower chlorine concentration and better chemical composition coordination in bast-fiber film mulching than these of polythene film mulching and no film mulching. So the bast-fiber film mulching in thermal insulation properties is better than no film mulching, and in rainwater collection is better than polythene film mulching. And the bast-fiber film mulching can increase the tobacco leaf yield and improve its quality.
