dimethoate n.樂果(一種有機磷殺蟲、殺螨劑)。

dimidiate

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 濃度分別為10mg l的樂果、馬拉硫磷和甲基對硫磷及ling l乙硫磷、三氯殺螨醇和三氟氯氰菊酯250ml在104鳳眼蓮培養液中的半衰期為236hr 、 77br 、 25hr 、 65hr 、 62hr和80hr ,而無鳳眼蓮對照培養液中的半衰期分別為338hr 、 274hr 、 226hr 、 236hr 、 114hr和365hr ,其降解速率分別提高了43

The result shows that the sources of pollutant mainly include non - point - source , line - source and point - source , with nh ( superscript + subscript 4 ) , no ( superscript - subscript 3 ) , so ( superscript 2 - subscript 4 ) , phenanthrene , bhc , fe and mn mainly from non - point - source , nh ( superscript + subscript 4 ) , hg , cd , cod , phenanthrene , bhc mainly from line - source , and so ( superscript 2 - subscript 4 ) , dimethoate and cn ( superscript - ) from point - source 研究結果表明,地下水污染源有面源污染、線源污染、點源污染;其中屬于面源污染的污染物主要有氨氮、硝氮、硫酸根、菲、六氯環已烷、鐵和錳;屬于線源污染的污染物主要有氨氮、汞、鎘、 cod 、菲、六氯環已烷等;屬于點源污染的污染物有硫酸根、樂果、氰化物。

Triazophos was a type of low - toxic , high - effective and broad - spectrum phosphorothioate pesticide and acaricide , which was developed in 1970s . it was thought to become the substitution of other pesticide such as methamidophos and dimethoate , so it had a good potential of application 三唑磷是20世紀70年代開發出的一種硫代磷酸酯類殺蟲殺螨劑,具有低毒、高效、廣譜的特點,是甲胺磷、樂果等農藥的換代產品,具有良好的應用前景。

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 高濃度( 50mg kg )的三氯殺螨醇對水稻、芋頭和喜旱蓮子草的生長有明顯抑制作用,其生物量分別為對照的30 . 72 、 37 . 19和25 . 05 ,但對美人蕉的影響不明顯。

The order of uptake amount of a same pesticide by plants was water hyacinth > rice > canna > taro > alligator > willow > tea plant , and the uptake of dimethoate was greater than that of dicofol 植物對不同農藥吸收量的大小為:鳳眼蓮>水稻>美人蕉>芋頭>喜旱蓮子草>柳樹>茶樹。相同植物對樂果的吸收大于三氯殺螨醇。

The methylene blue , congo red and dimethoate was use to photodegradation , and then some measures that can be referred were raised 選取亞甲基蘭、剛果紅和有機磷農藥樂果進行初步的室內、室外降解實驗,進而提出系統還需優化之處,可供相關人員參考。
