Reed nyom, goosegrass, thiab cov nyom dawb yog cov kab mob phem tshaj plaws hauv cov qoob loo, tshwj xeeb tshaj yog cov nyom nyom thiab cov nyom dawb. Cov hauv av stems tau tsim heev, thiab nws yog ib qho nyuaj rau tua lawv nrog cov tshuaj tua kab zoo tib yam, ua rau lawv nyuaj tshaj plaws los tshem tawm cov nroj tsuag malignant. Niaj hnub no, kuv yuav qhia rau koj txog ib tug me me rau kev tswj cov nroj tsuag malignant xws li reeds, goosegrass, thiab cov nyom dawb, uas yuav tshem tawm tag nrho cov malignant weeds. Weeding yog huv si thiab huv si.
Qhov tshwm sim yam ntxwv ntawm reed nyom
Reed nyom yog ib tsob nroj uas muaj xyoob ntoo uas tuaj yeem loj hlob ob qho tib si hauv dej thiab xerophytic. Nws loj hlob nyob rau hauv lub pas dej, ditches, thiab ntau yam qoob loo teb, thiab tau tsim heev underground stems. Nws tsuas yog reproduces los ntawm underground stems, yog tshav kub-resistant, tab sis tsis txias-resistant, yog li nws ua lub ntsiab teb nroj tsuag nyob rau hauv lub caij ntuj sov thiab lub caij nplooj zeeg. Vim nws muaj zog underground qia reproduction muaj peev xwm thiab muaj zog tshuaj tiv thaiv, nws dhau los ua ib qho nyuaj tshaj plaws malignant nroj tsuag kom tshem tawm hauv cov qoob loo.
Cov yam ntxwv tshwm sim ntawm Imperata cylindrica
Imperata cylindrica, feem ntau hu ua Imperata cylindrica hauv paus, yog cov nroj tsuag txhua xyoo uas loj hlob ntawm txoj kev, toj roob hauv pes, ditches, grasslands thiab qoob loo. Nws tsuas yog reproduces los ntawm underground rhizomes. Tom qab cov hauv paus hniav qhuav hauv huab cua, lawv tseem tuaj yeem muaj sia nyob thaum faus rau hauv av. Nws yog heev zog-intensive mus tshem tawm, thiab nws yog ib tug tawv nroj.
Kev xaiv cov tshuaj tua kab mob
Reed nyom thiab Imperata cylindrica yog ob qho tib si perennial malignant nroj tsuag. Kev tshem tawm ntawm phau ntawv tsis yog tsuas yog siv zog ua haujlwm xwb, tab sis kuj tseem muaj qhov tsis txaus ntseeg tswj cov nyom thiab nyuaj rau kev tshem tawm tag nrho. Kev tswj cov nroj tsuag tshuaj muaj qhov zoo ntawm kev ua haujlwm siab, ua haujlwm zoo, thiab kev tswj xyuas cov nyom zoo. Nws yog tam sim no dav siv nyob rau hauv ntau lawm. Kev sim tau pom tias glyphosate + high-efficiency flupyralid muaj kev tswj xyuas zoo ntawm cov nyom nyom thiab Imperata cylindrica.
Glyphosate kuj yog ib qho tshuaj tua kab mob uas muaj cov kab mob zoo. Nws tuaj yeem xa cov kua tshuaj mus rau cov hauv paus hniav los ntawm stems thiab nplooj, tua cov hauv paus hniav ua ke. Kev sib xyaw ntawm glufosinate thiab glyphosate nyob rau hauv ib qho kev faib ua feem muaj kev sib koom ua ke pom tseeb, kov yeej lawv cov kev tsis txaus siab, muaj kev tswj cov nroj tsuag dav, tua cov nroj tsuag sai dua thiab meej, thiab tus nqi tuaj yeem txo qis heev.
Glyphosate + high-efficiency flupyrazole muaj kev ua haujlwm zoo. Tom qab absorbed los ntawm stems thiab nplooj, cov tshuaj yuav kis tau los ntawm stems thiab nplooj mus rau ntau qhov chaw ntawm underground rhizomes, thiab tua tau saum toj no-av stems thiab nplooj thiab underground rhizomes nyob rau tib lub sij hawm. Nyob rau tib lub sijhawm, nws tuaj yeem kho cov tsiaj qus oats, bluegrass, foxtail nyom, bermudagrass, cyperus rotundus thiab lwm yam nroj tsuag malignant. Lub sijhawm ua haujlwm tau zoo tuaj yeem ncav cuag ntau dua 60 hnub, txo cov tswv yim ntawm kev ua haujlwm zoo heev.
Glyphosate kua yuav tsum tau xa mus rau hauv av rhizomes ntawm cov nroj tsuag ntau kom ua tiav cov nroj tsuag tswj cov nyhuv. Qhov no xav kom cov nroj tsuag muaj nplooj ntau dua. Yog hais tias cov nroj tsuag me me thiab photosynthesis tsis muaj zog ua ntej siv, cov as-ham khaws cia hauv cov hauv paus hniav yog ua los ntawm hauv qab mus rau saum. Lub sijhawm no, cov kua nkag mus rau cov hauv paus hniav me me, thiab cov nroj tsuag tua tsis ua tiav; Nyob rau hauv nruab nrab thiab lig theem ntawm cov nroj tsuag kev loj hlob, photosynthesis muaj zog, thiab photosynthetic khoom yog ua los ntawm sab saum toj mus rau hauv qab. Lub sijhawm no, cov nyhuv ntawm cov tshuaj yog qhov zoo tshaj plaws. Yog li ntawd, qhov tseem ceeb tshaj plaws ntawm kev siv glyphosate yog xaiv lub sijhawm zoo tshaj plaws los siv cov tshuaj.
Kev siv
Thaum lub sijhawm loj hlob ntawm cov nyom nyom, goose nyom, thiab cov nyom dawb, siv 30% glyphosate ammonium ntsev tov 300-500 ml + 10.8% high-efficiency flupyralid emulsifiable concentrate 30-45 ml / mu, ntxiv 30-50 kg dej thiab tshuaj tsuag tusyees, uas tuaj yeem tua cov nyom reed, goose nyom, thiab cov nyom dawb tsis pub dhau 10-15 hnub, thiab tuaj yeem kho cov tsiaj qus oats, bluegrass, bermudagrass, foxtail nyom thiab lwm cov nroj tsuag.
