摘　　要：为筛选适合云南中亚热带地区推广种植的优良紫花苜蓿品种,在云南省永德县对7个紫花苜蓿品种进行了4年的田间比较试验,对比分析了不同品种的生育期、主要营养成分和生产性能。结果表明:7个苜蓿品种均能在云南省永德县中亚热带地区完成生育期,其中“WL-525HQ”的生育期最短,为125d,“前景”的生育期最长,为131d;7个品种的干物质含量由高到低的顺序依次为“三得利”=“游客”>“甘农3号”>“多叶”>“WL-525HQ”>“前景”>“四季旺”,粗蛋白含量由高到低的顺序依次为“多叶”>“前景”>“四季旺”>“甘农3号”>“游客”>“WL-525HQ”>“三得利”;生长第2~4年,“游客”的干草、干物质和粗蛋白的总产量最高,分别为54744.3kg/hm 2、53695.31kg/hm 2和10633.86kg/hm 2,显著高于对照(CK)和其他品种(P<0.05)。在紫花苜蓿利用4~5年的情况下,“游客”可作为当地“粮改饲”苜蓿种植的主推品种。In order to select the excellent alfalfa varieties suitable for promotion and planting in the subtropical zone of Yunnan,a four-year field comparison experiment was conducted on 7 alfalfa varieties in Yongde County,Yunnan Province,and the growth period,main nutrient components and production performance of different varieties were compared and analyzed.The results showed that the seven alfalfa varieties could complete their growth period in the subtropical zone of Yongde County,Yunnan Province,among which the growth period of“WL-525HQ”is the shortest,125d,and the longest growth period of“prospect”is 131d.The order of the dry matter content of the 7 varieties from high to low is“Sanditi”=“Tourist”>“Gangnong No.3”>“Multi leaf”>“WL-525HQ”>“Prospect”>“Sijiwang”,the order of crude protein content from high to low is“Multi leaf”>“Prospect”>“Sijiwang”>“Gangnong No.3”>“Tourist”>“WL-525HQ”>“Sanditi”;In the 2nd to 4th year of growth,the total yields of hay,dry matter and crude protein were the highest among the“Tourists”,which were 54744.3kg/hm 2,53695.31kg/hm 2 and 10633.86kg/hm 2,respectively,which were significantly higher than those of the control(CK)and other varieties(P<0.05).In the case of alfalfa utilization for 4 to 5 years,“Tourists”can be used as the main variety of local“changing grain to forage”alfalfa cultivation.
