摘　　要：对美国引进的 5类 2 4个牧草品种进行了适应性比较试验 ,连续 2年的试验结果表明 ,一年生黑麦草类品种作为冬季种植产量较高 ,品质好 ;多年生黑麦草类和高羊茅类品种耐高温性和再生性强 ,可作为建植生产周期长的草地品种 ;鸭茅类品种适应性虽然较强 ,但在本地条件下产量低 ;雀麦类品种在冬季有一定的产量 ,但不耐高温 ,仅可作冬季栽培利用 ;在供试品种中 ,一年生黑麦草 Surrey和多年生黑麦草Five forage grass species, 24 varieties in total, Which introduced from USA were evaluated for their adaptation in Hangzhou, Zhejiang province, from October 1997 to June 1999. Annual ryegrass showed both high forage yield and good nutritive value in winter sowing. Perennial ryegrass and tall festuca had good heat tolerance, aftermath growth and persistence. Cocksfoot was adapted to the environmental conditions, but relatively low in forage yield. Bromegrass was heat sensitive and should be utilized by winter sowing. Annual ryegrass cv. Surrey and perennial ryegrass cv. Bison were recommended as the most promising varieties for winter sowing and permanent pasture establishing, respectively.
