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.
