云南北亚热带优良牧草品种混播组合试验研究

摘要

总结了在云南省昆明市官渡区小哨开展4年的牧草混播试验,并提出了在云南北亚热带气候条件下适宜刈割利用的牧草混播组合为非洲狗尾草＋三得利紫花苜蓿,以及三得利紫花苜蓿＋将军菊苣＋多年生黑麦草。建议混播播种量分别为：三得利紫花苜蓿15kg/hm2＋非洲狗尾草7.5kg/hm2;三得利紫花苜蓿10kg/hm2＋将军菊苣5kg/hm2＋多年生黑麦草10kg/hm2。%Four-year herbages mixed sowing test was carried out in Xiaoshao of Guandu District,Kunming City,Yunnan Province,and it was proposed that the herbages mixed sowing combination which was suitable for cutting utilization under the climatic conditions of north subtropical zone of Yunnan was Setaria grass+Suntory alfalfa and Suntory alfalfa+General chicory+perennial ryegrass.The seeding rates of mixed sowing were suggested as Suntory alfalfa 15 kg/hm2+Setaria grass 7.5 kg/hm2 and Suntory alfalfa 10 kg/hm2+General chicory 5 kg/hm2+perennial ryegrass 10 kg/hm2.
