为了筛选出适宜甘肃省及中国西北干旱、半干旱地区旱砂地栽培的枸杞品种,从宁夏、内蒙引进10个枸杞品种,并开展栽培对比试验,采用合理-满意度和多维价值理论合并规则的评价方法,对各品种幼树在树高、地径、冠幅、枝条数等营养生长方面进行量化比较。结果表明:‘宁杞5号’幼龄期营养生长表现最佳‘,蒙杞1号’、‘扁果枸杞’幼龄期营养生长表现较佳,为旱砂地可推广的生态功能型枸杞品种。

In order to select suitable Lycium varieties for cultivating in dry sand land in arid and semiarid region of Gansu Province and northwest China,10 varieties of Lycium were introduced from Ningxia and Inner Mongolia,and their cultural contrast tests were carried out.Using evaluation method of reasonable-satisfaction and multidimensional value theory combination rules,the vegetative growth indices of height,ground diameter,crown width and branch number of young tree of each variety were conducted quantitative comparison.The results showed that：Ningqi No.5 performed best on vegetative growth in juvenile period,next was Mengqi No.1 and Bianguogouqi,all of them could be varieties of ecological function for popularizing in dry sand land.
