为明确威宁球茎草芦在贵州不同区域的生长适应性，2008—2011年以当地主栽培牧草法恩（Fawn）苇状羊茅以及宝兴鸭茅为对照，对威宁球茎草芦在不同海拔区域的生物学性状、生产性能、抗逆性等进行了为期3年的综合测定。结果表明：威宁球茎草芦较对照品种具有更高的生产性能和更强的适应性，鲜草产量显著高于对照法恩（Fawn）苇状羊茅与宝兴鸭茅，是贵州省四季均衡供草、建立永久性混播草地及治理石漠化的优良草种。%For studying the productive adaptability and stability of Phalaris tuberosa L Cv. Weiningcaolu in different altitude areas, the botanical characteristics , biological characteristics, growth performance and stress resistance of Phalaris tuberosa L cv. Weiningcaolu were studied in 2008 to 2011, and Festuca arundinacea Schreb. cv. Fawn and Dactlis glomerata cv . Baoxing was used as CK. The results showed that the growth performance , produc- tive adaptability of Phalaris tuberosa L cv. Weiningcaolu were better than CK＇ s, the fresh yield and Dry matter yield was higher than CK＇ s, and there was difference in the fresh yield and Dry matter yield between Phalaris tuberosa L cv. Weiningcaolu and CK, Phalaris tuberosa L cv. Weiningcaolu was a good variety for establishment of Mixed - seeding Grassland and karst rock desertification control.
