摘要
对6个狼尾草属牧草在珠海市斗门区进行引种试验.结果表明:杂交狼尾草的节间数最少,分蘖数最多;热研4号王草的株高最高,节间数最多;象草新品系(MT-1)的鲜草产量最高,摩特矮象草的最低,分别为370 683.9、214 286.8 kg/(hm2·年),MT-1比摩特矮象草的鲜草产量高72.98%;在杂交狼尾草、MT-1、摩特矮象草3种牧草中,摩特矮象草的叶茎比最大,为0.79,且与其他2种牧草有显著差异,而其他2种牧草的叶茎比没有显著差异.
Test of introduced 6 varities of Pennisetum was conducted in Doumen area of Zhuhai city. The result showed that, the number of internodes of P. americanum ×P. purpureum were the least and the tillers were the most; plant height of P. purpureum ×P. typhoideum cv. Reyan No. 4 was the tallest, and the internodes were the most; the fresh grass yield (370 683.9 kg·hm-2·year-1) was the highest in P. purpureum (MT-1) and the lowest (214 286.8 kg·hm-2·year-1) in P. purpureum cv. Mott. The fresh grass yield of P. pu...
