摘要
对2003年引进的15个热带优良牧草进行了适应性试验研究,以筛选出适宜元谋干热河谷种植的优良品种。结果表明,参试的15个牧草在本地区均能越早,正常生长。产量排在前3位的品种为杂交臂形草、6901坚尼草、T58坚尼草,年均干草产量分别为28480kg/hm^2、25515.5kg/hm^2、24308.5kg/hm^2。杂交臂形草比对照品种1,2,3分别增产56.5%、123.9%、76.9%;6901坚尼草比对照品种1,2,3分别增产40.2%、100.7%、58.5%;T58坚尼草比对照品种1、2、3分别增产33.5%、91.2%、51%。总体看所有参试种质叶量比茎多,品质好。
some introduced high quality grazing were evaluated to select suitable forage for in the arid-hot valley of Yuanmou in 2003.the result shows: Fifteen high quality grazing grew well and could be over arid season.The average air-dry yield are more well for Brachiaria hybrida, Panicum maximum Jacq. CIAT T58 and Panicum maximum Jacq. CIAT 6901. The yield were 28 480 kg/hm^2, 25 515.5 kg/hm^2 and 24 308.5 kg/hm^2 respectively, Brachiaria hybridawere increased by 56.5%, 123.9%, 76.9%, Panicum maxinmum Jacq. CIAT 6901 were increased by 40.2%, 100.7%, 58.5% and Panicum maximum Jacq. CIAT T58 were increased by 33.5%, 91.2%, 51% in comparison with the CK of 3 varieties. As a whole the leaves are more than stems, It is high quality for fifteen grazing germplasms in the experiment.
