摘　　要：为丰富山东省适栽牧草种类,从南方引种5个狼尾草属牧草品种,连续开展2个生产周期的田间试验,观测其生长特性、产量及品质,用灰色关联度法进行综合评价,筛选出本地区最佳适栽品种。结果显示,在多茬刈割情况下,参试品种间各茬草的叶、茎比重及叶茎比差异大,株高差异不明显,其中紫色象草(RED)叶比重和叶茎比最大,‘热研4号’王草(RY4)、‘桂闽引’象草(GMY)和‘桂牧1号’杂交象草(GM1)茎比重较大。各参试品种平均全年鲜、干草产量分别为120.36、20.20 t/hm^(2),其中GMY、巨菌草(JJC)和GM1全年鲜、干草产量较其他参试品种高。参试品种各茬草CP含量均高于11%,品种间差异不显著(P>0.05),NDF、ADF和ADL含量在多数茬次内品种间的差异也不显著(P>0.05)。灰色关联度分析显示,GM1、GMY和RED产量和品质综合表现较好,适合在本地区推广种植。To enrich the suitable forage species in Shandong,this paper reports the observations on the growth traits,yield and quality of five Pennisetum varieties which were introduced from south China and planted for two production cycles from 2019 to 2020.The comprehensive evaluation was conducted with grey relational analysis to identify the most suitable varieties in this region.The results showed that the ratio of leaf/whole plant,the ratio of stem/whole plant and the ratio of leaf/stem of each crop of forage grass among the tested varieties were significantly different,and the plant height was not obviously different.The leaf/whole plant ratio and leaf/stem ratio of Pennisetum purpureum‘Red’(RED)were the largest,and the stem/whole plant ratio of P.purpureum×P.glaucum‘Reyan No.4’(RY4),P.purpureum‘Guiminyin’(GMY)and P.purpureum‘Guimu No.1’(GM1)were relatively high.The average yield of fresh and hay grass of the tested varieties were 120.36 and 20.20 t/hm^(2) respectively,and the fresh grass yield and hay yield of GMY,P.sinese(JJC)and GM1 were higher than those of other tested varieties.The results also showed that the CP content of each crop of forage grass of the varieties was higher than 11%,but the difference was not significant(P>0.05),and the content of NDF,ADF and ADL were also not significantly different among the varieties in most crops(P>0.05).The grey correlation analysis results indicated that GM1,GMY and RED had better comprehensive performance in yield and quality,and were suitable for promotion in this region.
