26个苜蓿品种引种筛选试验

在新疆地区引种国内外26个苜蓿品种,进行了3年的对比试验,结果表明大部分品种可以在该地区较好生长,具有较强的生态适应性,所测各指标表现良好。全能、巨人、皇冠、凯撒和新牧1号5个品种产草量较高,平均干草产量在11 600 kg/hm2以上,其中全能,巨人与皇冠,平均干草产量在12 000kg/hm2以上;干叶率(3年平均)5个品种均在40%以上,巨人可达到47.4%。产量低于9 000 kg/hm2的品种有北极星、日本03、荷兰、阿尔冈金、费纳尔和赛特,产量最低的品种是德宝,为7 152.8 kg/hm2。德宝和王后2个品种染病率极高,引种要特别慎重。

Screening of 26 introduced alfalfa varieties

The comparison of 26 introduced alfalfa varieties was carried out in Xinjiang and the result showed that most of the varieties could grow and adapt to local environment.The hay yields of Total+Z,AmeriStand,Phabulous,Caesar and Xinmu No.1 were higher than others and the average yield was more than 11600 kg/hm~(2),in which,the average hay yields of Omnipotence,AmeriStand and Crown were more than 12000 kg/hm~(2).The proportion of dry leaf of five varieties were more than 40%(average in 3 years) and AmeriStand was the highest(more than 47.4%).The hay yields of Polaris,Japan 03,Holand,Algonguin,Vernal and Sitel were less than 9000 kg/hm~(2),Derby was the lowest among them(only 7152.8 kg/hm~(2)).The disease resistance of Derby and AlfaQueen was poor,so it should be careful to introduce these varieties.
