Yuav Siv Atrazine Zoo Li Cas
Atrazine lub ntsiab formulations muaj xws li: 97% TC, 50% thiab 80% WP, 38% thiab 40% SC, thiab 4%, 8%, thiab 20% granules. Nws yog kev xaiv ua ntej- thiab tom qab- tshuaj tua kab mob tshwm sim. Nws tswj txhua xyoo broadleaf weeds thiab grasses, nrog zoo tswj ntawm broadleaf weeds tshaj li nyom, thiab kuj muaj ib co inhibitory nyhuv ntawm perennial weeds. Siv 200-250 ml ntawm 38% Atrazine SC ib evkawj ua ntej cov nroj tsuag tawm los yog thaum lawv nyob rau theem 1-3 nplooj. Vim nws cov nyhuv kav ntev, nws feem ntau sib xyaw nrog lwm cov tshuaj tua kab mob hauv kev tsim khoom kom txo tau cov tshuaj thiab txo cov phytotoxicity.
Atrazine's spectrum ntawm kev tswj cov nroj tsuag thiab kev ua tau zoo:
Kev ua tau zoo (tshaj li 90%) ntawm cov nroj tsuag: Amaranthus retroflexus, Chenopodium album, Purslane, Abutilon, Polygonum, Goosegrass, Setaria viridis
Kev ua tau zoo (70-90%) ntawm cov nroj tsuag: Echinochloa revoluta, Digitaria sanguinalis, Atractylodes lancea, Solanum nigrum
Kev ua haujlwm tsis zoo (50-70%) ntawm cov nroj tsuag: Amaranthus truncatula
Kev ua haujlwm tsis zoo (tsawg dua 50%) lossis tsis muaj txiaj ntsig ntawm cov nroj tsuag: Morning Glory, Field bindweed, Cyperus rotundus
Txawm li cas los xij, atrazine yog ib qho ntev -ntev ua ntej - tshuaj tua kab mob tshwm sim nrog ib nrab ntawm - lub neej ntawm 35-50 hnub hauv av. Clayey av hais kom nqus tau tus neeg sawv cev, ua rau muaj kev cuam tshuam ntev dua thiab kev puas tsuaj rau cov qoob loo tom ntej.
Ntau hom pob kws muaj qhov sib txawv rau atrazine. Yog li ntawd, nws yuav tsum tsis txhob siv nyob rau hauv inbred pob kws kab, qab zib pob kws, glutinous pob kws, paj kws teb, los yog pob kws noob teb. Nws yog qhov zoo tshaj plaws tsis txhob siv atrazine rau cov pob kws qab zib kom tsis txhob muaj phytotoxicity.
Thaum siv atrazine, yog tias cov kua drifts vim cua los yog daim ntawv thov tsis raug, nws tuaj yeem ua rau nplooj daj lossis curling nyob rau hauv cov neeg nyob sib ze, dib, taum, txiv duaj, poplars, thiab jujube ntoo, thiab thaum mob hnyav, nplooj poob. Cov qoob loo xws li nplej, nplej, spinach, dib, watermelons, txiv lws suav, cabbage, cauliflower, kale, thiab rapeseed tshwj xeeb tshaj yog rau atrazine.
Nyob rau hauv cov av, yog hais tias atrazine residues tshaj 0.080 mg ib kilogram, cabbage loj hlob yuav ho inhibited; yog tias nws siab tshaj 0.104 mg, cabbage loj hlob yuav txawv txav; thiab yog tias nws tshaj 0.081 mg, ncaj qha - noob japonica nplej loj hlob yuav txawv txav. Hauv lwm lo lus, txawm tias me ntsis ntawm atrazine residue nyob rau hauv cov av tuaj yeem ua teeb meem loj hlob rau cov atrazine no- cov qoob loo rhiab heev.
Qee cov kws tshawb fawb categorize cov qoob loo thiab zaub tsis kam rau atrazine ua plaub pawg:
Cov qoob loo tiv taus heev: pob kws, sorghum, thiab qab zib;
Cov qoob loo uas tsis muaj zog: sunflower, celery, zaub qhwv, thiab haus luam yeeb;
Cov qoob loo tsis muaj zog: kua txob, nplej, taum pauv, flax, thiab oats;
Cov qoob loo tsis muaj zog heev: dib, dib, txiv duaj, millet, thiab mov.
Raws li cov xwm txheej hauv zos, ceev faj thiab ceev faj yuav tsum tau ua thaum tig cov qoob loo thiab siv cov tshuaj atrazine kom txo lossis zam qhov tsis tsim nyog. Nws tau pom dav dav hauv kev lag luam uas ntws los yog leaching los ntawm cov ntawv thov atrazine tuaj yeem ua rau cov dej hauv av thiab cov dej nyob ib puag ncig. Cov ntawv ceeb toom tsis zoo ntawm atrazine kuj tau tshaj tawm hauv Tebchaws Europe thiab Tebchaws Meskas, nrog rau cov ntaub ntawv qhia txog kev cuam tshuam loj rau kev yug me nyuam ntawm Qav vim muaj kuab paug hauv dej thiab kev noj qab haus huv tib neeg.
Yuav ua li cas tiv thaiv cov teebmeem ntawm atrazine residues?
1. Sib sib zog nqus mus rau hauv av. Pib los ntawm kev tig nws ib zaug nrog lub plough sib sib zog nqus kom txav tau cov khoom seem atrazine los ntawm cov av saum toj mus rau hauv av hauv qab no.
2. Siv biofertilizer thiab zoo-rotted farmyard manure kom ceev cov decomposition ntawm residual atrazine. Rotary rau hauv av ob mus rau peb zaug tom qab thov.
3. Hloov mus rau sorghum lossis hloov cov txiv ntoo ua ntej. Txawm li cas los xij, thaum cog txiv hmab txiv ntoo, kho cov hauv paus hniav nrog rooting hmoov kom ceev cov hauv paus hniav tshiab.
4. Muab cov tshuaj tua kab mob hauv av nrog cov tshuaj tua kab mob kom tiv thaiv cov av- kab mob hauv paus. Qee qhov kev sim tau pom tias kev kho cov av nrog dichlorodiphenylmethane tuaj yeem txo qhov seem atrazine puas.
5. Siv ammonium nitrogen chiv kuj tuaj yeem txo atrazine puas rau cov qoob loo.
