摘　　要：16个月的研究结果表明 ,每次刈割后追施氮肥可显著提高坚尼草的干草产量和粗蛋白质含量。刈割周期以4 0～ 6 0 d为宜。刈次间干草产量差异不显著 ,但粗蛋白质含量随着刈割周期的延长而显著下降。参试的 3个坚尼草品种干草产量之间差异极显著 。months trial results showed: dry matter yield and crude protein of Panicum maximun Jacq. improved significantly fertilizing urea after cutting. The dry matter yield was significant difference negatively as well as CP content decreasing with longer cutting period during 40～60d cutting period. The dry matter yield was significant difference while CP conternt was negative among three P.maximum varieties.
