01

Action mechanism

Ametryn yog ib hom mestriazobenzene xaiv endothermic ua tshuaj tua kab mob tau los ntawm kev hloov kho tshuaj ntawm Ametryn.Nws yog ib tug raug inhibitor ntawm photosynthesis nrog ceev hericidal kev txiav txim.Los ntawm inhibiting lub hloov hluav taws xob hauv photosynthesis ntawm cov nroj tsuag rhiab heev, nitrite tsub zuj zuj hauv nplooj ua rau cov nroj tsuag raug mob thiab tuag, thiab nws cov kev xaiv muaj feem xyuam rau qhov sib txawv ntawm cov nroj tsuag ecological thiab biochemical tshuaj.

02

Cov yam ntxwv ua haujlwm

Nws tuaj yeem raug adsorbed los ntawm 0-5 cm av los tsim ib txheej tshuaj, kom cov nroj tsuag tuaj yeem tiv tauj cov tshuaj thaum lawv sprout los ntawm cov av.Nws muaj qhov zoo tshaj plaws tswj cov nyhuv ntawm cov nroj tsuag tshiab tshiab.Thaum tsis tshua muaj siab, Ametryn tuaj yeem txhawb kev loj hlob ntawm cov nroj tsuag, uas yog, txhawb kev loj hlob ntawm cov tub ntxhais hluas buds thiab cov hauv paus hniav, txhawb kev nce ntawm nplooj nplooj, qia thickening, thiab lwm yam;Thaum siab concentration, nws muaj zog inhibitory nyhuv ntawm cov nroj tsuag.Ametryn yog siv dav hauv cov qoob loo, citrus, pob kws, taum pauv, qos yaj ywm, taum mog thiab zaub ntug hauv paus los tswj cov nroj tsuag txhua xyoo.Thaum noj tshuaj ntau, nws tuaj yeem tswj tau qee cov nroj tsuag perennial thiab cov nroj tsuag dej, uas yog siv dav.

Kev sau npe

Raws li cov lus nug ntawm Tuam Tshoj cov ntaub ntawv tshuaj tua kab, txij li Lub Ib Hlis 14, 2022, muaj 129 daim ntawv pov thawj siv tau rau npe rau Ametryn hauv Suav teb, suav nrog 9 cov tshuaj qub, 34 tus neeg sawv cev ib leeg thiab 86 tus neeg sawv cev sib xyaw.Tam sim no, kev ua lag luam ntawm Ametryn feem ntau yog raws li cov hmoov ntub dej, nrog 23 cov hmoov dispersible hauv ib koob, suav txog 67.6%.Lwm cov ntaub ntawv muab tshuaj yog dej dispersible granules thiab ncua kev kawm ntawv, nrog rau 5 thiab 6 daim ntawv pov thawj siv tau raws li;Muaj 82 wettable hmoov nyob rau hauv lub compound, accounting rau 95%.

Cov khoom xyaw sib xyaw ua ke

Tam sim no, cov tshuaj tua kab mob tom qab sprout nyob rau hauv thaj av qab zib feem ntau yog sodium dichloromethane (amine) ntsev, Ametryn, Ametryn, diazuron, glyphosate thiab lawv cov sib tov.Txawm li cas los xij, cov tshuaj tua kab mob no tau siv hauv thaj chaw qab zib rau ntau tshaj 20 xyoo.Vim tias qhov pom tseeb tsis kam ntawm cov nroj tsuag rau cov tshuaj tua kab mob no, qhov tshwm sim ntawm cov nroj tsuag yog qhov hnyav dua, txawm tias ua rau muaj kev puas tsuaj.Kev sib xyaw tshuaj tua kab mob tuaj yeem ncua kev tiv thaiv.Ua kom tiav cov kev tshawb fawb hauv tsev tam sim no ntawm kev sib xyaw ntawm Ametryn, thiab sau qee cov ntsiab lus hauv qab no:

Amethryn · acetochlor: 40% acetochlor ametryn yog siv rau ua ntej yub cov nroj tsuag nyob rau hauv lub caij ntuj sov pob kws teb tom qab sowing, uas muaj kev tswj zoo tagnrho.Cov nyhuv tswj tau zoo dua li ntawm ib tus neeg sawv cev.Tus neeg sawv cev tuaj yeem nrov hauv kev tsim khoom.Nws raug pom zoo tias tus nqi ntawm 667 m2 yog 250-300 ml ntxiv rau 50 kg dej.Tom qab sowing, av ua ntej yub yuav tsum tau txau.Thaum txau, cov av saum npoo yuav tsum tau leveled, cov av yuav tsum ntub, thiab cov tshuaj tsuag yuav tsum sib npaug.

Ametryn thiab chlorpyrisulfuron: kev sib xyaw ntawm Ametryn thiab chlorpyrisulfuron nyob rau hauv thaj tsam ntawm (16-25): 1 pom tau tias muaj txiaj ntsig zoo.Tom qab txiav txim siab tias tag nrho cov ntsiab lus ntawm kev npaj yog 30%, cov ntsiab lus ntawm chlorpyrisulfuron + Ametryn = 1.5% + 28.5% yog qhov tsim nyog dua.

2 Methyl · Ametryn: 48% sodium dichloromethane · Ametryn WP muaj kev tswj tau zoo ntawm cov nroj tsuag hauv thaj av qab zib.Piv nrog 56% sodium dichloromethane WP thiab 80% Ametryn WP, 48% sodium dichloromethane thiab Ametryn WP nthuav dav cov tshuaj tua kab mob thiab txhim kho kev tswj xyuas.Cov nyhuv tswj tag nrho yog qhov zoo thiab muaj kev nyab xeeb rau cov suab thaj.

Nitrosachlor · Ametryn: Qhov kev txhawb nqa tsim nyog ntawm 75% Nitrosachlor · Ametryn wettable hmoov yog 562.50-675.00 g ai / hm2, uas tuaj yeem tswj tau cov kab mob monocotyledonous, dicotyledonous thiab dav-leaved nroj nyob rau hauv cov nroj tsuag qab zib thiab muaj kev nyab xeeb rau kev loj hlob ntawm cov nroj tsuag.

Ethoxy · Ametryn: Ethoxyflufen yog diphenyl ether herbicide, uas yog siv los kho av ua ntej yub.Nws muaj kev tswj xyuas siab rau txhua xyoo broadleaf nyom, sedge thiab nyom, ntawm cov uas tswj cov nyhuv ntawm broadleaf nyom yog siab dua li cov nyom.Nws muaj kev nyab xeeb rau cov ntoo txiv ntoo los tswj cov nroj tsuag txhua xyoo hauv cov txiv hmab txiv ntoo nrog acetochlor · Ametryn (38% tshem tawm tus neeg sawv cev), thiab qhov koob tshuaj zoo tshaj plaws yog 1140 ~ 1425 g / hm2.
