摘　　要：2004-2006年对陇东地区的半干旱区(环县)和半湿润区(宁县和西峰)15个紫花苜蓿Medicago stiva品种干草产量与气象要素进行分析得出,降水是影响紫花苜蓿干草产量增加的关键因子,其次是平均气温,而日照时间和≥0℃积温能满足紫花苜蓿生长需求。同时,引进品种在半湿润区以两年生最佳,第3年产量开始下降。在半干旱区随着种植年代的增加,产量逐年增加。分析得出,适宜宁县种植的品种有:甘农1号、新疆苜蓿、苜蓿王、皇冠、金皇后、大富豪、三得利、牧歌401、巨人201、赛特;适宜西峰种植的品种有:巨人201、金皇后、甘农1号、苜蓿王、新疆苜蓿、赛特、三得利、牧歌401、皇冠、阿尔冈金;适宜环县种植的品种有:牧歌401、金皇后、三得利、皇冠、阿尔冈金、新疆苜蓿、甘农1号、苜蓿王、大富豪、赛特。Based on the analysis of the yield of 15 alfalfa varieties and meteorological factors in semi-arid area （Huanxian） and semi-humid areas （Ningxian and Xifeng） with the data from 2004 to 2006, the results indicated that the predipitation was the key factor for affecting the yield, and temperature took the second place. The sunshine hours could meet the demand of alfalfa growth in these areas. The yield of introduced varieties reach the highest in second year and it decreased from third year in semihumid areas. However, it increased along with the growth time in semiarid areas. The suitable varieties for Ningxian County were Gannong No. 1, Xinjiang, Alfaking, Phabulous, Golden Empress, Millionair, Sanditi, AmeriGraze 401, AmeriStand 201, Sitel; those suitable for Xifeng County were AmeriStand 201, Golden Empress, Gannong No. 1, Alfaking, Xinjiang, Sitel, Sanditi, AmeriGraze 401, Phabulous, Algonquin; those suitable for Huanxian County were AmeriGraze 401, Golden Empress, Sanditi, Phabulous, Algonquin, Xinjiang, Gannong No. 1, Alfaking, Millionair, Sitel.
