台湾象草引种研究

对2003年从台湾引进的台湾象草（Pennisetum purpureum cv.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35.75 t·hm-2，比桂牧1号杂交象草(P.purpureum cv.Mott）×(P.americanum×P.purureum) cv.Guimu No.1]（26.76 t·hm-2）、华南象草（P.purpureum cv.Huanan）（23.34 t·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 study on introduction of Pennisetum purpureum cv. Guiminying

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 cv.Mott)×(P.americanum×P.purureum) cv.Guimu No.1](26.76 t·ha-1) and P.purpureum cv.Huanan(23.34 t·ha-1),respectively.In addition,as P.purpureum 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.
