为保护河西生态、保障粮食安全、优化种植业结构，恢复河西走廊冬小麦规模化种植很有必要。通过分析河西走廊种植冬小麦所具有的多方面优势，针对该区域冬小麦扩种中存在的问题，提出了河西走廊扩大种植冬小麦的发展对策是:加强优质节水高产抗病新品种选育，建设优质小麦生产基地；深入开展粮菜结合、农牧结合复种配套栽培技术研究；加强耕作栽培管理；做好麦蚜及小麦黄矮病发生预测预报、综合治理防控研究工作；政府需改变政策导向，加大支持力度。

Growing winter wheat in Gansu's Hexi Corridor has several advantages, which benefits to ecological protection, food security, and crop structure optimization. By analyzing the advantages and difficulties of winter-wheat production in the region, the authors suggest that it is necessary to develop a strategy for breeding new wheat varieties with the characteristics of high yield, high quality, water-efficiency, and disease resistance; building high-quality wheat production bases; expanding wheat-vegetable integration, optimizing crop-livestock circulation; improving farm management; and predicting and controlling of pests(such as wheataphid) and diseases (such as yellow dwarf). Government policy should also be adjusted to support the technological shifts.
