摘　　要：通过9种雀稗属牧草品种的比较试验,分析其产量和营养成分。结果表明:9个品种年平均干物质产量差异极显著,其中黑籽雀稗(PaspalumatratumBra.)最高,达23.3 t/hm2;牧草产量的季节动态变化规律较稳定,各年度季节动态曲线均呈单峰型,高峰出现在7月份,3月份产量最低;营养价值以黑籽雀稗最高。An experiment on comparison of nine accessions of Paspalum in forage yield and nutritional values was conducted. The results showed that P. atratum Bra grew most vigorously and yielded the highest (23.3 ton/ha) among the nine accessions. The seasonal yield varied in a stable pattern. Their annual seasonal yield was characterized by a single- peak curve. They all yielded highest in July and lowest in March. P. orbiculare had the highest nutritional value among the nine accessions, followed by P. dilatatum Poir.
