摘　　要：根据陇东旱塬气候和区域特点,从栽培管理、病虫防治和种薯贮藏等方面提出了适于该区域马铃薯脱毒种薯的繁育模式。结果表明,在陇东旱塬区,马铃薯种薯繁育地块应选则塬周通风较好区域;繁育品种选择喜湿热、抗逆性广的中早熟品种;微型薯块要经催芽、包衣和分切处理;播种应抢茬浅种,适当起垄,覆膜催苗,出苗后及时分次培土;主要防治蚜虫、晚疫病和环腐病,要定期加强预防;收获应杀秧早收,严防霜冻和混杂;贮藏期定期进行通风和窖内消毒。On introducing the climatic and regional characteristics of Eastern Gansu dryland farming areas, the article discusses the virus-free seed potato breeding system from the cultivation management, diseases and pests control, seed potato storage. The results show that, in the Eastern Gansu dryland farming areas, farmers should select well ventilated areas around Plateau as breeding lands, and take potatoes with characteristics of damp and heat resistance, wide stress resistance and medium-early maturity as breeding cultivars. The tubers should be sprouted, coated, parted off and sowed shallowly, and after emergence of the seedlings, farmers should hilling up in time, and strengthen the control of aphid, late blight, ring rot disease. The potatoes should be harvested early, and disinfected and ventilated periodically at the storage stage.
