19个豆科牧草品种在川东地区的适应性评价研究

Study on the Adaptability of 19 Leguminous Forage Varieties in the East of Sichuan

从2010年开始,在四川达州试验点连续三年对19个多年生豆科牧草种的物候期、生长速度、越夏率、产草量、茎叶比进行观察测定。结果表明,在参试的19个品种中,有10个紫花苜蓿(Medicago sativa L.)品种和4个白三叶(Trifolium repens L.)品种能够适应当地气候条件,顺利越夏;年干草产量能够>10t/hm2的有紫花苜蓿品种凯伦、马瑞拉、杰利、Adrenalin、皇冠、德宝、飞马、Spyder、渝苜1号、凉山紫花苜蓿和白三叶海法、考拉、拉丁诺;连续三年累计干草产量>30t/hm2的品种有凉山紫花苜蓿和白三叶考拉、海法、拉丁诺,可在本区域推广利用。

The adaptability of 19 perennial leguminous forage varieties was studied in the Forage and Fodder Workstation of Dazhou from 2010 to 2013 by testing phenophase, growth speed, summer rate, yield, stem-leaf ratio. Results showed that there were 10 varieties of alfalfa （Medicago sativa L.） （Karen, Marley, Jerry, Adrenalin, Crown, Pegasus, Spyder,fly-horse, Yumu NO.1 and Liangshan） and 4 varieties of white clover （Trifolium repens L.） （Haifa, Koala and Latin） could adapt to the local climate and be able to achieve the hay yield 〉 10t/hm2 per year. The hay yield of Liangshan alfalfa and white clover of Haifa, Koala and Latin were more than 30t/hm2 per year, which could promote the utilization in the east of Sichuan.
