Abstract: Aimed at the situation of limited rainfall and misproportion of season distribution in Longdong dryland, especially with the problem of drought during winter wheat’s growing, from improving its growth environment, cultivation condition and utilizing rate of rainfall, the experiment was conducted to evaluate utilizing rate of rainfall of winter wheat’s furrow-film cultivation which was organically combined furrow catchment with plastic mulching. The research showed that adopting film-furrow cultivation style may overcame any malpractice of low utilizing rate of natural rainfall etc. It increased 13.7 kg/ (hm2·mm) in utilizing rate of moisture, increased 766g/ m2 in white wheat’s calculative dry substance during returning green to maturity , increased 23.86% in its yield than regular cultivation style of open field. It is the best cultivation style that effectively utilizes natural rainfall and realizes high and stable yield of white wheat in Longdong dryland.
