摘要：

为探索适宜在半干旱风沙区进行种植的苜蓿(Medicago sativa)品种,在宁夏中卫市东园镇瑞应村进行引种试验。从7个苜蓿品种的根长、根重、株高、主枝侧枝数、茎叶比、干鲜比、产草量等方面进行比较研究。结果表明:1甘农4号紫花苜蓿株高、茎叶比、干鲜比均较大,且显著高于其他供试苜蓿品种(P<0.05);鲜草产量则是甘农8号最大,且与株高、主枝侧枝数存在明显的相关性;2主成分分析显示,根长、鲜根重、株高和主枝侧枝数对紫花苜蓿的综合生长性状影响较大;3隶属函数综合评价结果表明,甘农3号、甘农4号的得分比较高,各项指标和性状较好,是中卫市瑞应村适合种植的苜蓿品种;皇后的生产性能较差,不适宜在该地区建植多年生牧草地。

摘要：

In order to explore the suitable planted varieties in semi-drought and sandy area of Alfalfa( Medicago sativa),the introduction experiment was conducted in Zhongwei city of Ruiying village. A comparative study of the 7 Alfalfa Varieties on root length,root weight,height,number branch trunk,stem weight / leaf weight,dry weight / fresh weight,grass yield and other aspects was done. The results showed that:( i) Gannong No. 4 alfalfa plant height,SW / LW,DY / FY were large,and significantly higher than the other tested varieties of Alfalfa( P < 0. 05); Fresh yield was Gannon on the 8th maximum,and there was a significant correlation with plant height,number branch trunk;( ii) Principal component analysis showed that root length,fresh root weight,height and number branch trunk of alfalfa had greater impact on overall growth traits;( iii) The subordinate function of comprehensive evaluation results showed that the gannong No. 3,gannong No. 4 high score,the better indicators and character,was suitable for planting in Zhongwei city of Ruiying village; Queen's weakest performance,not suitable for planting perennial grassland construction in the area.
