| 摘 要： | 为陕西榆林风沙草滩区筛选出适宜种植并能大面积推广的优良品种，对引进的19种紫花苜蓿的株高、生物量和叶茎比等农艺性状进行比较。研究表明：株高以骑士丁(87.67 cm)显著最高，三得利(47.33 cm)显著最低；主根直径以WL168(5.95 mm)显著最大，Bara 416(3.48 mm)显著最低；生物量鲜重以421Q、威纳尔和啊迪娜显著最高；生物量干重则以康赛、啊迪娜和WL319紫花苜蓿品种显著最高；WL319、游侠和WL343紫花苜蓿的叶茎比显著高于其它16个品种。综上表明，WL319的干草产量、叶茎比及株高几个指标均表现良好，更适宜在榆林风沙草滩区种植和推广。

| Abstract: | In order to screen out good varieties suitable for planting and large scale promotion in wind sand grass shoal area of Yulin, the plant height, biomass and leaf stem ratio of 19 introduced alfalfa were compared. The results showed that the plant height was significantly higher in Jiaying (87.67cm) and significantly lower in Sundeli (47.33cm). The taproot diameter of WL168(5.95mm) was significantly largest, and that of Bara 416(3.48mm) was significantly lowest. The biomass fresh weight of 421Q, Werner and Adina were significantly highest. The biomass dry weight was significantly higher in Kangsai, Adina and WL319 alfalfa varieties. The leaf stem ratio of WL319, Ranger and WL343 alfalfa was significantly higher than that of other 16 varieties. In conclusion, WL319 has good performance in hay yield, leaf stem ratio and plant height, and is more suitable for planting and promotion in wind sand grass shoal area of Yulin. |
