【摘要】 对6个坚尼草品种进行比较试验,结果表明:坚尼草TD58、坚尼草Mombassa、热研8号坚尼草和热研9号坚尼草产量之间差异不显著,但显著高于坚尼草CIAT6299,其中,热研9号坚尼草年均产量18140.46kg/hm2;坚尼草TD58其年均干物质产量达到17402.42kg/hm2,仅次于热研9号坚尼草,两者产量均显著高于坚尼草CIAT6299和青绿黍。青绿黍年种子产量达640kg/hm2,坚尼草TD58仅次于热研9号坚尼草,种子成熟比较一致。更多还原

【Abstract】 Six varieties of Panicum maximum Jacq were compared in terms of dry matter yield in a trial.The result of a 3 years trial shows that there is no significant difference in dry matter yield among P.maximum cultivars TD58,Mombassa,Reyan 8 and Reyan 9 but they yielded evidently higher than P.maximum cv.CIAT 6 299.The Reyan 9 yielded the highest in dry matter,upto 18 1 40.46 kg/hm2,followed by the TD58(17 402.42 kg/hm2),and these two cultivars yielded obviously higher than the CIAT 6 299 and the green panic grass(P.maximum var.trichoglume).The green panic grass produced 640 kg of seeds per ha,the highest,followed by the TD58 the seeds of which mature rather uniformly and are easy to harvest.更多还原
