5个牧草鸭茅品种(系)在贵州南部地区的种子产量

摘要

为了探明贵州优质牧草鸭茅种子的开发利用价值,以5个鸭茅品种(系)为材料,于2009-2011年在贵州省草业研究所独山基地进行了种子产量比较试验.结果表明,黔草4号鸭茅种子的产量最高,为472.5 kg/hm2,显著高于对照楷模鸭茅(166.5 kg/hm2)和大拿鸭茅(139.5 kg/hm2),可作为贵州当家牧草鸭茅品种替代国外引进品种,并可大量繁殖种子应用于生产.%In order to confirm the development and utility value of Guizhou local eximious pasture D. glomerata, seed yield trials of five D. glomerata cultivars were carried out during 2009 - 2011. The results showed that the seed yield of Qiancao 4 was the highest(472. 5 kg/hm2), significantly higher than the control Kaimo(166. 5 kg/hm2) and (139. 5 kg/hm2). The cultivar Qiancao 4 could replace the imported varieties and become the main D. glomerata cultivar in Guizhou, its seeds could be produced abundantly and be promoted in application.
