摘　　要：在落叶松苗圃中使用33%二甲戊乐灵乳油、41%草甘膦水剂、24%乙氧氟草醚乳油、50%扑草净可湿性粉剂及24%乙氧氟草醚乳油+12.8%吡氟氯禾灵乳油进行化学除草试验。结果表明:2250mL/hm2的33%二甲戊乐灵乳油在落叶松播后芽前使用,除草效果良好;在落叶松幼苗期,使用50%扑草净可湿性粉剂2250g/hm2除草效果和持效期最好,41%草甘膦水剂4500mL/hm 2、24%乙氧氟草醚乳油+12.8%吡氟氯禾灵乳油(1200+750)mL/hm2效果稍次之。The trial of of chemical weeding of Larix principis-rupprechtii of pendimethalin 33% EC, glyphosate 41% AS, oxyfluorfen 24% EC, prometryn 50% WP and oxyfluorfen 24% EC ＋ haloxyfop 12.8% EC were tested in nursery. The results showed that 2250 mL/ha pendimethalin 33% EC had better effect before the bud after sowing. In the seedling stage, herbicidal effects and the validity of prometryn 50% WP with 2250 g/ha were best; the contol effect of glyphosate 41% AS 4500 mL/ha and oxyfluorfen 24% EC ＋ haloxyfop 12.8% EC （1200 ＋750） mL/ha took second place.
