摘要
从2000～2002年通过小区试验,对美国、加拿大和中国的6个豆科牧草材料在内蒙古锡林郭勒盟苏尼特右旗荒漠草原地区的适应性、产量和质量进行了比较研究,目的是评价牧草的适应性,筛选适合当地种植的优良牧草。研究结果表明,草原3号苜蓿和阿尔岗金苜蓿的适应性强,夏播翌年返青率在80%以上,产量较高,分别为7125.29kg/hm2和1648.17kg/hm2,极显著高于润布勒苜蓿和雀沃依斯苜蓿(P<0.01),而且粗蛋白质含量较高,可作为荒漠草原地区推广种植的优良牧草。
The experiment on the adaptation and evaluation of 6 legumes from the United States of America,Canada and China was conducted in desert steppe in Suniteyou Banner of Xilinguole League,Inner Mongolia from 2000 to 2002 in order to evaluate their adaptation and to select the forages to be planted in the desert steppe zone.The overwinter survival rates of both Medicago varia Martin. cv.Caoyuan No.3 and Medicago sativa L.cv.Algonguin were over 80%.Medicago varia Martin. cv.Caoyuan No.3 had the greatest yields of 7125.29 kg/hm^2 than Medicago sativa L.cv.Algonguin(1648.17 kg/hm^2),and had higher content of crude protein than the others. Its adaptation to the desert environment, high productivity,and good quality makes them suitable for planting in the desert steppe zone.
