More than 70 % of the amount of ethion , dicofol , and cyhalothrin uptaken by canna maintened at roots , and this ratio increased with the decreasing of water solubility of the pesticide Ss 。美人蕉吸收的乙硫磷、三氯杀螨醇和三氟氯氰菊酯中，有voo ， o以上富集于植物根系中，且在根系中的富集程度随农药水溶解度的下降而增加。
37 . 19 % , and 25 . 05 % as those grown in soils without dicofol , though all the test plants grown well in soils with 5 ing / kg of dicofol and 50 mg / kg of dimethoate . canna could tolerate 50 nig / kg of dicofol and dimethoate 高浓度( 50mg kg )的三氯杀螨醇对水稻、芋头和喜旱莲子草的生长有明显抑制作用，其生物量分别为对照的30 . 72 、 37 . 19和25 . 05 ，但对美人蕉的影响不明显。
The concentrations of ethion , dicofol , and cyhalothrin in planted willow cutting soils were decreased to 1 . 65 mg / kg , 0 . 07 rag / kg , and 0 . 23 % nig / kg respectively from 5 mg / kg in 8 weeks of treatment in field condition , which were 80 . 88 % , 3 . 93 % , and 39 . 66 % as those in unplanted soils 培养8周后，乙硫磷、三氯杀螨醇和三氟氯氰菊酯在种植柳树扦插苗土壤中的残留浓度分别由5mg儿g下降到1石smg以g 、 0 07mg版g和0 23mg儿g ，分别为不种植任何植物的对照土壤中的残留浓度的so
There were no visible morphological change in water hyacinth exposed to a mixture of ethion , dicofol , fenvalerate , fenpropathrin , deltamethrin , and cyhalothrin with the concentrations of 0 . 01 mg / l , 0 . 1 mg / l , and 1 mg / l , but the fresh biomasses were increased by 49 . 79 % , 40 . 34 % , and 83 . 88 % respectively compared to those planted in water solutions without pesticides 植物在5mg kg三氯杀螨醇及50mg kg和5mg kg乐果的环境中生长良好。动力学研究结果表明，植物对有机农药的净化过程符合一级动力学反应。凤眼莲对水溶液中有机农药的净化效率很高。
The removal dynamics of pesticides by plants was corresponded with the first order kinetic reaction . the half lives of dimethoate , malathion , and methyl parathion with a concentration of 10 mg / l , ethion , dicofol , and cyhalothrin with a concentration of 1 mg / l in 250 ml planted with 10 - 11 g water hyacinth were 236 hrs , 77 hrs , 25 hrs , 65 hrs , 62hrs , and 80 hrs , and those in unplanted water solutions were 338 hrs , 274 hrs , 226 hrs , 236 hrs , 114 hrs , and 365 hrs respectively 浓度分别为10mg l的乐果、马拉硫磷和甲基对硫磷及ling l乙硫磷、三氯杀螨醇和三氟氯氰菊酯250ml在104凤眼莲培养液中的半衰期为236hr 、 77br 、 25hr 、 65hr 、 62hr和80hr ，而无凤眼莲对照培养液中的半衰期分别为338hr 、 274hr 、 226hr 、 236hr 、 114hr和365hr ，其降解速率分别提高了43
