摘　　要：为探索干旱地区土壤保水的有效措施,研究了不同起垄覆膜方式对土壤水分及烤烟前期生长发育的影响。结果表明,覆膜有利于提高土壤含水量,从而有利于烟株生长对水分的需求,覆膜土壤含水量高于不覆膜土壤,覆膜烟株生长及抗逆性明显高于不覆膜烟株。不同起垄覆膜方式相比较,土壤含水量及烟株前期生长指标及抗逆性表现为:冬前起凹垄,覆膜>起凹垄,覆膜>起凸垄,覆膜>起凸垄,不覆膜,说明提早起垄、垄面为凹形并进行覆膜处理是干旱地区提高烤烟移栽质量,促使烟株早生快发,增强烟株抗逆性的有效手段之一。In an attempt to establish an efficient keeping soil moisture in drought area, the effect of different ridge-forming and film-covering modes on soil moisture and prophase growth of flue-cured tobacco was studied. The results indicated that film-covering was propitious to increase soil moisture content and demand for water of tobacco seedling. The soil moisture content and tobacco seedling growth was more in film-covering than no film- covering area. The tobacco seedling had stronger antiadversity in film-covering area. The soil moisture content, tobacco seedling growth and antiadversity was the most in concave ridge-forming and film-covering area before winter, and more in concave ridge-forming and film-covering area, and less in protruding ridge-forming and film- covering area, and the least in protruding ridge-forming and no film-covering area in different ridge-forming and film-covering modes. It explain the concave ridge-forming and film-covering ahead of time was one of the efficient measure to enhance the soil moisture and prophase growth, antiadversity of tobacco seedling in arid area.
