| 摘 要： | 2005、2006和2007年，分别在景洪市嘎洒镇选取海拔为550、560和846 m的3个试验点，种植新引进的杂交臂形草1号（Brachiaria brizantha Mulato 1)、杂交臂形草2号（B.brizantha Mulato 2)、热研3号俯仰臂形草（B.decumbens cv.Reyan No.3）和热研6号珊状臂形草（B.brizantha cv.Reyan No.6），进行比较试验。结果表明，4种牧草均有分蘖数多、产量高、生产性能稳定，营养价值高、适口性好、容易刈割，抗病力强、对土壤和气候条件的要求不高、适应性强、容易种植、便于推广等优点。热研3号俯仰臂形草、热研6号珊状臂形草根系发达，利于控制水土流失，也有利于草地防火，一次种植可长期受益，建议在西双版纳州、德宏州和海南省推广种植；杂交臂形草1号和杂交臂形草2号出苗快、孕穗期长、抽穗期晚、茎叶比小、适口性更好、消化利用效率更高，建议重点推广应用。

| Abstract: | During 2005 to 2007, a comparative experiment of 4 introduced species (cultivars) of Brachiaria genus, including Brachiaria brizantha Mulato 1, B.brizantha Mulato 2, B.decumbens cv. Reyan No.3 and B.brizantha cv. Reyan No.6, was carried out at 3 experimental plots with different altitudes (560, 550 and 846 m) in Gasa township of Jinghong city, Xishuangbanna Dai Autonomous Prefecture. The Results showed that all of them grew well at experimental plots and had advantages of more tillers, higher yield, stable production performance, higher nutritional value, lower proportion of stem to leaf, palatability, easy mowing, disease resistance, less demanding on the soil and climate conditions, stronger adaptability, easy to plant and extend in a large area. The root system of B.decumbens cv. Reyan No.3 and B.brizantha cv. Reyan No.6 developed well, which was beneficial to control soil erosion and to prevent grassland fire, and had long term benefits once planted. The B.brizantha Mulato 1 and 2 were faster germination, longer booting stage, later heading stage and smaller ratio of stem to leaf than those of B.decumbens cv. Reyan No.3 and B.brizantha cv. Reyan No.6. Thus, we conclude that the 4 Brachiaria species (cultivars) are suitable for planting in the areas and should be extended in Xishuangbanna, Yunnan province. |
