摘　　要：从黄土高原冬小麦根系发育的一般规律与其经济产量相关问题出发，分析了干旱胁迫对冬小麦根区制约的主要障碍因素，并从抗旱丰产角度阐述了耕作改土、种群轮作、品种利用、合理施肥、覆盖栽培、集水稳根等调控小麦根系发育生境的有效措施。Main impediment factors in drought stress on winter wheat root system are analyzed from a point of the correlation between the general law of Loess Plateau winter wheat root system development and its economic yields. Some effective practices of adjustment and control over wheat regional eco environment such as tillage and improvement of soil, crop rotation, inter cropping, variety selection, rational fertilizer application, mulching cultivation, catching water in root region and etc. are discussed in the paper so as to provide directions for water saving and hgih efficient production of winter wheat in Loess Plateau.
