摘　　要：为保持树势，增加桑树产叶量，同时为减少采叶用工量，减轻劳动强度，采取春蚕期重剪梢，夏蚕期截条收获，中秋蚕改春出扦为秋出扦，实行全年条桑收获法。试验结果表明，晋南蚕区单位面积产叶量增产19．2％～21．1％，晋东南蚕区增产14．4％～15．4％，采叶功效提高了40．5％。To remain the tree vigor and increase the leaf yield, in the meantime to reduce the amount of labor used in picking leaves and alleviate labor intensity, an all-year-round harvest method was adopted by cutting the top shoot in spring silkworm rearing season and harvesting the shoot in summer, and adjusting the traditional practices for remaining the stumps from spring to autumn in mid-autumn silkworm rearing season. The results show the per unit area of leaf yield in southern Shanxi province improved by 19.2% to 21. 1%, and 14.4% to 15.4% for southeast Shanxi province, and the leaf picking efficiency increased by 40.5 %.
