Khoom Description
Paraquat 20% AS cuam tshuam cov thylakoid membrane qauv hauv chloroplasts, sai sai nres photosynthesis thiab chlorophyll synthesis. Pom kev puas tsuaj (discoloration) tshwm sim 2-3 teev tom qab daim ntawv thov foliar, nrog kev ua tiav tiav hauv 24 teev. Nws zoo ua rau ob qho tib si monocot thiab dicot ntsuab cov ntaub so ntswg thaum sparing non-photosynthetic qauv. Thaum cov av sib cuag, nws sai sai deactivates yam tsis muaj kev puas tsuaj rau cov hauv paus hniav lossis cov noob hauv av.
Khoom Description
Paraquat yog ib qho uas tsis yog - xaiv, hu rau tshuaj tua kab mob sai sai thiab dav -spectrum efficiency. Raws li bipyridyl cation, nws yog absorbed sai sai los ntawm cov nplooj nplooj thiab txo kom dawb radicals nyob rau hauv cov ntaub so ntswg ntsuab los ntawm photosynthesis thiab ua pa. Cov radicals no ua rau nws pib- oxidation, tsim hydrogen peroxide thiab oxygen dawb radicals uas cuam tshuam cov thylakoid daim nyias nyias, nres photosynthesis thiab chlorophyll synthesis, thaum kawg ua rau desiccation.
Cov yam ntxwv tseem ceeb:
Ua ntej- daim ntawv thov tshwm sim: Poob kev ua haujlwm ntawm cov av sib cuag, ua rau nws muaj kev nyab xeeb rau cov qoob loo tawm tshiab
Xaiv qhov kev txiav txim: Ineffective on brown bark; nyab xeeb rau woody cog trunks
Lub teeb- nyob ntawm: Kev ua tau zoo nce nrog lub hnub ci; huab cua huab cua ncua kev cuam tshuam
Daim ntawv thov nqi: 20% aqueous tov ntawm 30-45 mL / 100m² nrog 3-4.5 kg dej rau tom qab sau stubble thiab teb cov nroj tsuag (nplej, mov) los yog orchard / plantation nroj tsuag tswj
Spectrum: Tswj cov nroj tsuag txhua xyoo zoo; muaj zog suppresses perennials (txawm tias qhov chaw hauv av tuaj yeem tshwm sim)
Kev siv cov khoom siv: Cov vaj txiv hmab txiv ntoo, thaj teb mulberry, cog roj hmab, thaj teb, tsis muaj- txog kev ua liaj ua teb, thiab tsis yog- thaj chaw qoob loo
Cov tshuaj tua kab no muaj txiaj ntsig tshwj xeeb rau ua ntej -cov nroj tsuag tswj cov nroj tsuag hauv ntau cov qoob loo, suav nrog cov qoob loo dav - kab xws li pob kws, qab zib, thiab taum pauv, qhov twg tuaj yeem tau tshuaj tsuag. Nws cov av- qhov xwm txheej tsis muaj zog tso cai rau lub sijhawm siv tau yooj yim hauv kev ua liaj ua teb.
