| 摘 要： | 引进美国冷季型禾本科牧草品种19个，在苏南（南京）和苏北（徐州）进行生态适应性试验。初步结果表明，多花黑麦草和杂交黑麦草产量较高，且集中于春季，尤其是四倍体品种鲜草产量最高。多年生黑麦草虽然产量也较高，但在苏南不能安全越夏。苇状羊茅和鸭茅在江苏能较好地越夏。

| Abstract: | Nineteen cool-season forage grass cultivars were introduced from Oregon,USA to Jiangsu, China. Ecological adaptability was evaluated in southern (Nanjing) and northern (Xuzhou) Jiangsu. It was shown that annual ryegrass (Lolium multiflorum) and intermediate ryegrass( Lolium hybridum) had the highest yield with a spring peak. Especially, tetraploid cultivars had the highest fresh grass yield. Although the yields of Perennial ryegrass ( Lolium perenne) cultivars were high, they could not survive the summer in southern Jiangsu. Orchardgrass(Dactylis glomerata) and tall fescue (Festuca arundinacea) could be oversummer well in Jiangsu province. |
