Abstract: The field experiments for the flue-cured tobacco cultivation with ridge plastic mulching, ditch plastic mulching and without mulching were conducted during 2000 and 2001 in the main flue-cured tobacco area of Tianshui City. The results showed that the plastic mulching was effective on increasing temperature and keeping soil moisture. The ditch plastic mulching was the best among them. The growing period of flue-cured tobacco advanced significantly, the speed of growth was accelerated, and the proportion of middle and superior tobacco and output value had improved, under the ditch plastic mulching.

Key words: Plastic mulching cultivation, Plastic mulching cultivation, Flue-cured tobacco, Ecology, Growth effect
