摘　　要：在河北低平原区,夏播情况下对4类禾本科饲草(10个品种)进行了比较试验。结果表明,高丹草类鲜草产量最高,苏丹草类干草产量最高,干草产量苏丹草类,高丹草类及青贮玉米类差异不显著,但均显著高于狼尾草类;所有参试品种粗蛋白产量差异均不显著;所有品种中健宝高丹草鲜草产量和粗蛋白产量最高,夏播可收获2茬,分蘖能力、再生能力和抗病性均较强;牧特利狼尾草粗蛋白含量最高,分蘖能力最强,抗病性最强。综合分析以健宝高丹草表现最优,宜作为河北低平原区禾本科饲草推广的首选品种。The comparison experiments for four gramineal forage crops （10 varieties summer-sowed）were conducted in the lowland area of Hebei Province. The result showed that Sorghum bicolor and Sorghum sudanerise obtained the highest yield in fresh matter base,Sorghum sudanense obtained the highest yield in dry matter base. The yields （dry matter）of Sorghum bicolor,Sorghum sudanense and Sorghum sudanense were not significantly different from that of Ze. mays, but they were much higher than that of Pennisetum americanum P. purpureum. The crude protein yields of all tested varieties did not show significant difference. Out of all tested varieties,Jumbo performed best in terms of grass yield and crude protein yield,it could be harvested twice. Nutrifeed performed best in terms of crude protein content, tillering capacity and disease resistance. Based on the integrated performance,Jumbo was the best variety to be extended in the lowland area of Hebei Province.
