台湾象草区域试验研究

Regional trial of Pennisetum purpureum Schum cv.Taiwan

于2006--2008年在广西南宁、百色、湖南长沙3个不同生态区以桂牧1号杂交象草为对照，对广西畜牧研究所引进的台湾象草进行了区域试验。结果表明：台湾象草适应性广，生长速度快，干草产量（46351．32～53903．84kg／hm2）比对照桂牧1号杂交象草（41919．12～44137．66kg/hm2）增加10．02％～23．73％，草质柔软，蛋白质含量（10．5％）比对照高冉9．4％，是适应性极强的优质牧草，可在亚热带地区应用推广。

During 2006 to 2008, a regional trial of Pennisetum purpureum Sehum cv.Taiwan, bred by Guangxi institute of animal science, was carried out in three different ecological zones in Nauning, Baise and Changsha, using [（Pennisetum purpureum cv.Mott）x（P. americanum x P.purpureum）] cv. Guimu No.l as control. The results showed that Pennisetum purpureum Schum cv.Taiwan grew fast, had wide adaptability, cold resistance. Average hay yield of Pennisetum purpureum Schum cv.Taiwan was 46351.32-53903.84 kg/hm2, increased by 10.02%-23.73% compared with control [（Pennisetum purpureum cv.Mott）×（P.arnericonum × P.purpureum ）] cv. Guimu No.1 （41919.12-44137.66 kg/hm2）.The quality of the grass was soft, protein content （10.5%） increased by 9.4% compared with control. Pennisetum purpureum Schum cv.Taiwan was an excellent forage.
