| 中文摘要: |
| 采用田间试验方法开展了β助剂、迈丝、益泽、激健4个喷雾助剂对氰氟草酯和灭草松的减量使用技术研究。结果表明,使用100 g/L氰氟草酯乳油防除稻田杂草稗Echinochloa crusgalli、千金子Leptochloa chinensis时,分别添加β助剂、益泽、激健3个喷雾助剂均可降低其使用量30%,添加迈丝可降低其使用量20%;使用480 g/L灭草松水剂防除多花水苋Ammannia multiflora、丁香蓼Ludwigia prostrata和异型莎草Cyperus difformis 等杂草时,添加β助剂可降低其使用量30%,分别添加迈丝、益泽、激健3个喷雾助剂均可降低其使用量至少20%。两种稻田常用除草剂减量20%~30%后添加喷雾助剂施用对水稻生长和产量均无不良影响。 |
| 英文摘要: |
| Field experiment was conducted to detect the reduction of cyhalofop-butyl and bentazone by mixing with 4 spray adjuvants of beta, Maisi, Yize and Jijian. The results showed that for control of Echinochloa crusgalli and Leptochloa chinensis in rice fields, the dosage of 100 g/L cyhalofop-butyl EC could be reduced by 30% when mixed with spray adjuvants either beta, Yize or Jijian, 20% while mixed with Maisi. For control of weeds such as Ammannia multiflora, Ludwigia prostrate and Cyperus difformis, the dosage of 480 g/L bentazone AS could be reduced by 30% when mixed with beta adjuvant, 20% while mixed with either Maisi, Yize or Jijian. The 20%-30% reduction of two herbicides and the addition of spray adjuvants had no adverse effect on the growth and yield of rice. |
