摘　　要：对2003年从台湾引进的台湾象草(Pennisetum purpureumcv.Guiminying)进行了品种比较试验、区域试验以及生产试验。结果表明,台湾象草适应性广泛,抗寒,产草量高,年干草产量35.75t.hm-2,比桂牧1号杂交象草[(P.purpureumcv.Mott)×(P.americanum×P.purureum)cv.Guimu No.1](26.76t.hm-2)、华南象草(P.purpureumcv.Huanan)(23.34t.hm-2)分别提高了33.59%和53.19%。此外,台湾象草再生性好,蛋白质含量高,达10.5%,氨基酸总量达7.89%,具有较高的营养价值,有望成为亚热带地区优良牧草品种。A series of studies on performances of Pennisetum purpureum cv. Guiminying introduced from Taiwan in 2003 were conducted, including the plot, field and production trials. The results showed that P. purpureum cv. Guiminying had a wide adaptability, cold resistance and high yield. The average of annual hay yield of P. purpureum cv. Guiminying was 35.75 t· ha^-1 , increased by 33.59% and 53.19 compared with control （P. purpureum ev. Mott）× [（P. araericanum × P. purureum） cv. Guimu No. 1] （26.76t · ha^-1） and P. purpureurn cv. Huanan （23.34 t · ha^-1）, respectively. In addition, as P. purpu- reum Schum cv. Guiminying grew fast and grass was soft. Furthermore, The protein and amino acids contents of this variety were higher by 10.5% and 7.89%, respectively. Therefore,P. purpureum cv. Guiminying has a higher nutritive value than other comparisons and it should be one of excellent forages in the subtropical region.
