| 摘 要： | 针对陇东旱作农业区年降水量少、季节分布不均，特别是冬小麦生产中干旱问题，从改善旱地冬小麦生长环境和栽培条件、提高降水利用率入手，将小垄沟集水和覆膜保墒技术有机地结合在一起，进行了旱地冬小麦膜沟栽培水分利用率研究。研究表明，采用膜沟方式栽培，可克服自然降水利用率低等弊端，使使水分利用率（WUE）较露地平播提高13.7kg/(hm2·mm)，冬小麦返青期—成熟期干物质积累较露地平播提高766g/m2；冬小麦单产较传统露地平播栽培增产23.86%。是陇东旱地冬小麦自然降水高效利用、实现高产稳产的最佳模式。

| 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. |
