摘　　要：通过对烤烟大田三种不同覆盖方式的覆盖效应比较表明：液体地膜在改善烟田土壤水热状况和促进烤烟生长方面有积极作用,液体地膜具一定的增温保湿效应,0～20 cm耕层较对照土壤温度平均增幅为0.9℃,土壤含水量平均提高1.2%。液体地膜覆盖能够在一定范围内克服普通塑料地膜覆盖的负面效应,而且省工省时,有利于土壤生态环境的改善。The comparison result of mulching effects of three different mulching ways for fluecured tobacco field showed that liquid film mulching had active effect in improving water ＆ temperature condition of soil and promoting growth of flue～cured tobacco.Liquid film mulching had effect of improving soil temperature and conserving soil water to a certain extent.Compared with contrast treatment,the soil temperature in the tillage layer between 0～20 cm was raised by 0.9℃ on the average and the water content of soil also was raised by 1.2% on the average Liquid film mulching can overcome negative effect of plastic film mulching to a certain degree.It also can save both labor and time and improve soil entironment.
