摘　　要：观察测定3种不同留茬设置下刈割后的华北驼绒藜的再生情况,综合分析其长势及产量。结果显示,9～10cm留茬设置植株高度最高,达到(41.27±11.06)cm;6～7cm留茬设置分蘖数最多,达到(40.17±10.27)条;产草量最高的为6～7cm留茬设置。由试验结果可以得出,6～7cm留茬设置是华北驼绒藜刈割留茬的最佳设置。Regenerations after mowing were measured at three different stubble settings of Ceratoides arborescens, and the growth and production were comprehensively analyzed. Plants with 9-10 cm stubble setting had the maximum heights,which were （41.27±11.06） cm ;plants with 6-7 cm stubble setting had the most tiller numbers,which reached to（40.17±10.27） strips;plants with 6-7 cm stubble setting also had the highest yield. This experiment shows that, 6-7 cm stubble setting is the best setting of mowing stubble for Ceratoides arborescens.
