Comprehensive evaluation on nutrition value of 11 introduced alfalfa varieties in Inner Mongolia

以内蒙古地方品种敖汉紫花苜蓿为对照,对引进的11个国外紫花苜蓿品种2个茬次的营养成分进行了综合分析和量化评估,并运用灰色关联度分析法评价各品种的营养价值的优劣。结果表明,第1茬和第2茬以地方品种敖汉的营养价值高于引进品种;引进品种第1茬的苜蓿王和第2茬的金皇后,为引进品种中最高。同时,敖汉、苜蓿王、大富豪、农宝、费纳尔、WL232、WL232HQ等品种,其第1茬的营养价值要高于第2茬。综合两个茬次,以敖汉苜蓿的营养价值最高,其次为苜蓿王和阿尔冈金,这两个外国品种可适当推广种植。
