| 摘 要： | 在温室内采用单轴等效线法测定大豆苗后除草剂灭草松与精喹禾灵联合作用的结果表明 ,灭草松与精喹禾灵混用对马唐有增效作用 ,随着灭草松的剂量从 0增加到 60 0 ga .i./hm2 ,精喹禾灵抑制马唐 90 %的有效剂量 (ED90 )随之从 14.88ga .i./hm2 下降到 4 .89ga .i./hm2 。当灭草松与精喹禾灵以低剂量混用时 ,对反枝苋表现为拮抗作用 ,而两者以高剂量混用时 ,表现为增效作用

| Abstract: | The experiment of evaluating entazon-quizalofop-P-ethyl joint-action was conducted in greenhouse. The method of Single Axial Isoble was used in the experiment. The result showed bentazon-quizalofop-P mixture had synergism to Digitaria sanguinalis. As the dosage of bentazon increased from 0 to 600 g a.i./ha, the ED 9 0 value of quizalofop-P to D. sanguinalis decreased from 14.88 g a.i./ha to 4.89g a.i./ha. When the combinations of bentazon-quizalofop-P were in low dosages, they had antagonism to Amaranthus retroflexus; In higher dosages, they had synergism. |
