河西走廊冬小麦种植的问题及发展对策

Problems and Development Strategy of Winter Wheat Production in Hexi Corridor

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.
