| 摘 要： | 对引自国内外17个苜蓿品种的耐寒性、抗病性与生产性能等主要生物学形状,于2002—2004年进行了田间栽培比较试验研究,结果表明:在耐寒性的表现上,17个品种中,在冬季地表具有厚积雪的条件下,除了霍普兰德和WL323越冬率低于85%外,其它品种均在90%以上;新牧1号杂花苜蓿和阿尔冈金在其它品种染病均严重的情况下,表现出较强的抗病能力,受害面积比例低于20%以下;王后、DK120、霍普兰德、WL323、DK134、新牧1号、德宝和三得利,其生长和再生生长速度表现较快;从各品种的干草产量来看,多数品种表现出具有较高的生产性能,年可收4茬草,DK124、DK120、德宝、亮牧2号、霍普兰德5个品种第一年就均超过了10000kg/hm2。从生育期、生长特性、抗病性、干草产量等方面综合评价,以新牧1号杂花苜蓿表现最为优秀,其次为DK124、亮牧2号和霍普兰德。

| Abstract: | From 2002 to 2004, the studies on main biological characteristics of 17 alfalfa varieties, including cold - resistance, disease - resistance, production capability etc. , were carried out. The result showed that as far as cold- resistance was concerned, among 17 alfalfa varieties, expect the winter survival rate of the Hopland and WL323 were less than 85%, that of the others was all above 90%; compared with the other alfalfa varieties, Xinmu No. 1 and Aergangjin showed high disease - resistance ability,especially when the other alfalfa varieties were seriously damaged, the damage rate of Xinmu No. 1 and Argangjin were below 20%; the growth and regeneration speed of Queen, DK120, Hopland, WL323, DK134, Xinmu No 1,Debao,Sandeli showed faster; the hay yield of most alfalfa varieties showed high production capability, all of them could be harvested 4 times; hay yield of DK124, DK120, Debao, Liangmu No. 2, Hopland was more than 10 000 kg/hm2 in the first year. According to synthetic appreciation of growth duration, growth traits, disease - resistance and hay - yield, Xinmu No. 1 was the best, the next were DK124, Liangmu No.2 and Hopland. |
