| 摘 要： | 采用随机区组试验方法，选取阔叶杂草分布均匀的地块。苯磺隆设2个浓度，采取不同时间喷药和添加助剂2种方式用药，以不施药为对照，综合评价不同处理的防效及对小麦生长的影响，探讨苯磺隆在南疆地区冬麦田减量施用的可行性。结果表明，同一施药时间，添加助剂处理对阔叶杂草的防效和小麦产量增幅与不添加助剂处理结果相当；苯磺隆12ga．i．／hm2处理4月613施药对阔叶杂草的防效和小麦产量的增幅均优于3月24日施药2浓度处理的防效和产量增幅，与苯磺隆18ga．i．／hm2处理的防效和小麦产量增幅相当，在试验条件下对小麦生长安全，无药害。 |

| Abstract: | A field trial was established as a randomized block experiment and the level of broadleaf - weeds infestation was determined before spraying. Tribenuron - methyl 10% WP alone and with additive were sprayed to control broadleaf weeds and the yield of wheat was measured at harvesting time. Tribenuron - methyl 10% WP at 12 g a. i/hm2 sprayed in early April better controlled broadleaf weeds than when sprayed in late March. Within the same application time, additives did not improve the efficacy of tribenuron -methyl 10% WP. Tribenuron -methyl 10% WP with the dosage of 12 - 18 g a. i/ hm2 can be applied to control broadleaf weeds without affecting the growth of wheat. |
