| 摘 要： | 采用模拟除草剂水体残留的方法研究了稻田3种常用除草剂二甲四氯钠、苄嘧磺隆、丁草胺水体残留对水葫芦生长的影响。结果显示:水体中不同浓度的3种除草剂对水葫芦生长均有影响,其中3.36 mg/L二甲四氯钠处理的水葫芦植株的药害症状最为明显,0.10 mg/L苄嘧磺隆处理的次之,4.25 mg/L丁草胺处理的最小。3种除草剂不同浓度处理下水葫芦干物质产量、分株数均随除草剂浓度的增加而降低。

| Abstract: | The effects of three herbicides(MCPA-Na,bensulfuron-methyl and butachlor,generally applied in paddy field) residues in water on the growth of water hyacinth were studied by simulation of herbicides concentrations.The results showed that three herbicides residues in water had significant phytotoxicity to water hyacinth following the order of 3.36 mg/L MCPA-Na> 0.10 mg/L bensulfuron-methyl> 4.25mg/L butachlor.The dry biomass and tiller number of water hyacinth were decreased with the increase of residues concentration of three herbicides in water. |
