摘　　要：通过不同间隔时期对多年生黑麦草、白三叶混播草地牧草产量的监测与分析 ,得出随着休闲期的增加 ,青绿物质和死亡物质均呈现上升趋势 。Different length of rest intervals between defoliations effects on perennial ryegrass/white clove sward mass were investigated. The results showed that growth of new plant tissue and loss to senescence increased as the intervals extended, thus both high and low sward mass conditions resulted in a decline in herbage growth rate.
