摘　　要：夏秋人工草地剩余牧草收贮是云贵高原人工草地合理利用的关键措施之一 ,青贮是牧草收贮的切实可行的方案。牧草收贮可调节牧草供应季节平衡 ;促进牧草再生 ,提高草地产量 ,改善利用均匀度 ,控制杂草 ,防止草地退化 ;提高牧草利用率 ,减少牧草枯腐 ;提高牧草质量和消化率 ;减少冬春青绿饲料生产及精饲料供给量 ,降低生产成本 ;Reaping and storing up surplus herbage is one of key measures to rationally utilize sown pasture and silaging is a feasible plan in the Yunnan Guizhou plateau of China during summer and autumn. If surplus herbage is reaped and stored up, the seasonal balance of herbage supply can be regulated; the regenerate of herbage can be improved, pasture yield can be raised and more uniformly utilized, weeds and pasture degeneration can be controlled; herbage utilization ratio will be raised and withered or putrid grass will be reduced; quality and digestion coefficient of pasture grass may be improved; a good supply of concentrate and soiling crop can be dropped in winter and spring, so the cost of production can be cut down; as a result, economic benefit of pasture agriculture must be raised and sustainablly developed.
