摘要
在云南怒江干热河谷地区对引进的16个禾本科热带牧草进行区域适应性研究,结果表明,参试的16个牧草品种(品系)均能适应云南怒江干热河谷气候。在产量方面,红象草(Pennisetum purpureumcv.Red)产量最高,干草产量达35 915.00 kg/hm2,极显著高于参试的其他15个牧草品种(P<0.01)。其次是热研8号坚尼草(Panicum maxi mumcv.Reyan No.8)、热研9号坚尼草(P.maxi mumCIAT9)、TD58坚尼草(P.maxi mumcv.TD58)和热研6号珊状臂形草(Brachiariabrizanthacv.Reyan No.6),以上4个牧草品种产量之间差异不显著(P>0.05),但显著高于杂交臂形草(B.hybrid)(P<0.05),极显著高于参试的其他10个牧草品种。红象草、热研8号坚尼草、热研9号坚尼草、TD 58坚尼草、热研6号珊状臂形草等牧草品种饲草产量高、生长迅速、刈割再生能力强、抗旱性强,适宜在干热河谷地区推广种植。
An experiment was conducted to assess the suitability of sixteen tropical grass varieties at the Nujiang dry-hot valley areas in Yunnan province.The results of this study showed that 16 varieties performed well at Nujiang dry-hot valley region.Pennisetum purpureum cv.Red showed the highest yield of hay with 35 915.00 kg/hm2,and was extremely significant higher yield than the other 15 varieties.Panicum maximum cv.Reyan No.8,P.maximum CIAT 9 and P.maximum cv.TD 58 and B.brizantha cv.Reyan No.6 had the second ...
