Glyphosate - tau dhau los ua cov tshuaj tua kab loj tshaj plaws hauv ntiaj teb los ntawm kev tsim khoom thiab muag khoom
Herbicides feem ntau muab faib ua ob pawg: tsis xaiv thiab xaiv.Ntawm lawv, cov nyhuv tua ntawm cov tshuaj tua kab mob tsis xaiv rau ntawm cov nroj tsuag ntsuab "tsis muaj qhov sib txawv", thiab ntau yam tseem ceeb suav nrog glyphosate.Glyphosate nrog cov tshuaj formula C3H8NO5P tau dhau los ua cov khoom siv tshuaj tua kab ntau tshaj plaws hauv ntiaj teb los ntawm kev tsim thiab muag.
Txawm hais tias glyphosate yog ib qho tshuaj tua kab uas tsis yog xaiv, nws yog ib qho dav-spectrum herbicide nrog rau sab hauv nqus thiab conduction.Nws cov nyhuv weeding zoo heev, tuaj yeem tswj tau lub sijhawm ntev heev ntawm kev ua, cov nyhuv tseem ceeb heev.Ntxiv mus, glyphosate tuaj yeem degraded sai los ntawm cov kab mob tom qab sib cuag nrog av.Yog li, glyphosate muaj qhov zoo ntawm kev ua haujlwm siab, tsis muaj tshuaj lom thiab tsis tshua muaj residue, uas yog tshwj xeeb tshaj yog haum rau kev ua liaj ua teb.Nws kuj tau siv dav hauv kev ua haujlwm ntawm cov roj hmab, mulberry, tshuaj yej, orchard thiab lwm yam nroj tsuag kev lag luam, uas yog ib qho zoo guarantee rau nce yield thiab ruaj khov sau nyob rau hauv cog.
Txij li thaum xyoo 1980, raws li kev kawm txawv teb chaws cov thev naus laus zis, Tuam Tshoj pib tshawb fawb thiab tsim cov kev tsim cov glyphosate.Los ntawm kev ua kom zoo thiab txhim kho tas mus li, cov thev naus laus zis tau dhau los ua neeg paub tab, thiab kev lag luam nplai tau txuas ntxiv nthuav dav.Xyoo 2021, muaj peev xwm tsim tau tag nrho ntawm 1.13 lab tons ntawm glyphosate nyob rau hauv lub ntiaj teb, ntawm uas Tuam Tshoj lub peev xwm ntau lawm mus txog 760,000 tons, accounting rau ntau tshaj 60%, thiabTuam Tshojtau dhau los ua qhov chaw tsim khoom loj tshaj plaws hauv ntiaj teb.Hauv ob xyoos dhau los, kev tsim cov glyphosate hauv tsev tau txuas ntxiv mus, thiab tag nrho cov peev txheej tsim tawm hauv tsev tau tshaj 800,000 tuj.s ib perxyoo 2022.
Peb lub tuam txhab tau tsim los rau 10 xyoo thiab glyphosate ib txwm yog ib qho ntawm peb cov khoom zoo tshaj.Tso zis txhua xyooisntau tshaj 10,000tons, xa tawm mus rau ntau tshaj 20 lub teb chaws thoob ntiaj teb.Lub glyphosate synthesis technology ntawm peb lub tuam txhab tau mus txog lub thoob ntiaj teb advanced theem, thiab kev koom ua ke unit noj nyob rau hauv lub forefront ntawm kev lag luam..Peb tos ntsoov ua haujlwm nrog koj.
