Paclobutrazol, uniconazole, Mepiquat chloride, Chlormequat, qhov sib txawv thiab kev siv ntawm plaub txoj kev loj hlob regulators

Cov yam ntxwv ntawm plaub
Paclobutrazol, uniconazole, Mepiquat chloride, thiab Chlormequat tag nrho yog nyob rau hauv qeb ntawm cov nroj tsuag kev loj hlob regulators.Tom qab siv, lawv muaj peev xwm tswj cov nroj tsuag kev loj hlob, inhibit cov nroj tsuag vegetative kev loj hlob (kev loj hlob ntawm saum toj no-av qhov chaw xws li stems, nplooj, ceg, thiab lwm yam), thiab txhawb kev loj hlob (txiv hmab txiv ntoo, stems, thiab lwm yam. elongation ntawm underground ib feem). , tiv thaiv cov nroj tsuag los ntawm kev loj hlob zoo thiab leggy, thiab ua si lub luag haujlwm ntawm dwarfing cov nroj tsuag, shortening lub internodes, thiab txhim kho kev ntxhov siab.
Nws tuaj yeem ua rau cov qoob loo muaj paj ntau dua, ntau txiv hmab txiv ntoo, ntau tillers, ntau pods, thiab ntau ceg, nce chlorophyll cov ntsiab lus, txhim kho photosynthesis efficiency, thiab muaj txiaj ntsig zoo ntawm kev tswj kev loj hlob thiab nce yield.Nyob rau tib lub sijhawm, tag nrho plaub tuaj yeem nqus tau los ntawm cov cag ntoo, stems thiab nplooj, tab sis kev siv ntau dhau los yog ntau dhau yuav muaj kev cuam tshuam rau cov nroj tsuag kev loj hlob, yog li yuav tsum tau them nyiaj tshwj xeeb.
Qhov sib txawv ntawm plaub

Paclobutrazol (1) Paclobutrazol (2) Bifenthrin 10 SC (1)

1. Paclobutrazol
Paclobutrazol yog undoubtedly qhov feem ntau siv, dav siv, thiab loj tshaj plaws-muag triazole cog kev loj hlob regulator nyob rau hauv lub lag luam.Nws yog ib tug inhibitor synthesized los ntawm endogenous gibberellins.Nws tuaj yeem txo qis kev loj hlob ntawm cov nroj tsuag, tswj qhov zoo tshaj plaws ntawm stems, txhawb kev sib txawv ntawm tillers thiab paj buds, khaws paj thiab txiv hmab txiv ntoo, txhawb cov hauv paus kev loj hlob, txhim kho photosynthetic efficiency, thiab txhim kho kev ntxhov siab.Nws muaj txiaj ntsig zoo heev rau kev sib deev, thiab lwm yam.

Nyob rau tib lub sijhawm, vim tias nws yog thawj zaug tsim los ua cov qoob loo fungicide, nws kuj muaj qee yam kab mob bactericidal thiab nroj tsuag, thiab muaj kev tswj tau zoo heev ntawm cov kab mob mildew, fusarium wilt, anthracnose, rapeseed sclerotinia, thiab lwm yam.

Paclobutrazol tuaj yeem siv dav hauv ntau cov qoob loo, cov qoob loo nyiaj ntsuab thiab cov qoob loo txiv hmab txiv ntoo, xws li nplej, nplej, pob kws, rape, soybean, paj rwb, txiv laum huab xeeb, qos yaj ywm, kua, citrus, cherry, txiv nkhaus taw, lychee, txiv duaj, txiv duaj, haus luam yeeb. , lwm..Ntawm lawv, cov qoob loo cog qoob loo thiab cov qoob loo ua lag luam feem ntau yog siv rau kev txau rau hauv cov yub theem thiab ua ntej thiab tom qab lub paj tawg.Txiv hmab txiv ntoo feem ntau yog siv los tswj lub crown zoo thiab inhibit kev loj hlob tshiab.Nws tuaj yeem raug txau, yaug lossis irrigated.Nws muaj kev cuam tshuam loj heev rau rapeseed thiab nplej seedlings.
Nta: daim ntawv thov dav, kev tswj kev loj hlob zoo, kev ua haujlwm ntev, kev ua haujlwm lom neeg zoo, yooj yim ua rau cov av seem, uas yuav cuam tshuam rau kev loj hlob ntawm cov qoob loo tom ntej, thiab tsis haum rau kev siv mus ntev.Rau cov phiaj xwm uas siv Paclobutrazol, nws yog qhov zoo tshaj plaws los ua kom cov av ua ntej cog qoob loo tom ntej.

2.uniconazole

HTB1wlUePXXXXXXFXFXXq6xXFXXXBCChemical-hauv-cog-growth-regulator-Uniconazole-95 HTB13XzSPXXXXXaMaXXXq6xXFXXXkChemical-in-cog-growth-regulator-Uniconazole-95 HTB13JDRPXXXXXa2aXXXq6xXFXXXVCChemical-hauv-cog-growth-regulator-Uniconazole-95
Uniconazole tuaj yeem hais tias yog ib qho kev hloov kho tshiab ntawm Paclobutrazol, thiab nws cov kev siv thiab kev siv yog ib yam li Paclobutrazol.
Txawm li cas los xij, vim tias uniconazole yog carbon ob daim ntawv cog lus, nws cov kev ua haujlwm lom neeg thiab cov tshuaj muaj txiaj ntsig yog 6-10 npaug thiab 4-10 npaug siab dua li ntawm Paclobutrazol feem.Nws cov av seem tsuas yog 1/5-1/3 ntawm Paclobutrazol, thiab nws cov tshuaj muaj txiaj ntsig yog qhov kev lwj sai dua (Paclobutrazol tseem nyob hauv av rau ntau tshaj li ib nrab xyoo), thiab nws qhov cuam tshuam rau cov qoob loo tom ntej tsuas yog 1/5. Paclobutrazol.
Yog li ntawd, piv nrog Paclobutrazol, uniconazole muaj zog tswj thiab bactericidal nyhuv ntawm cov qoob loo thiab muaj kev nyab xeeb rau kev siv.
Nta: muaj zog ua tau zoo, tsis tshua muaj residue, thiab muaj kev nyab xeeb siab.Nyob rau tib lub sijhawm, vim tias uniconazole muaj zog heev, nws tsis haum rau kev siv hauv cov yub yub ntawm cov zaub feem ntau (Mepiquat chloride tuaj yeem siv tau), thiab nws tuaj yeem yooj yim cuam tshuam rau kev loj hlob ntawm seedlings.

3. Mepiquat chloride

Mepiquat Chloride (2) Mepiquat Chloride 1 mepiquat chloride 3
Mepiquat chloride yog ib hom tshiab ntawm cov nroj tsuag kev loj hlob regulator.Piv nrog Paclobutrazol thiab uniconazole, nws yog mos, tsis khaus thiab muaj kev nyab xeeb dua.
Mepiquat chloride tuaj yeem siv tau rau hauv txhua theem ntawm cov qoob loo, txawm tias nyob rau hauv cov yub thiab paj theem thaum cov qoob loo yog cov tshuaj rhiab heev.Mepiquat chloride yeej tsis muaj kev phiv tshwm sim thiab tsis ua rau phytotoxicity.Nws tuaj yeem hais tias muaj kev nyab xeeb tshaj plaws ntawm kev ua lag luam.Plant Loj hlob Regulator.
Nta: Mepiquat chloride muaj kev nyab xeeb siab thiab lub neej txee dav.Txawm li cas los xij, txawm hais tias nws muaj kev tswj hwm kev loj hlob, nws txoj kev ua tau zoo yog luv luv thiab tsis muaj zog, thiab nws cov kev tswj kev loj hlob kuj tsis zoo.Tshwj xeeb tshaj yog rau cov qoob loo uas loj hlob zuj zus, feem ntau xav tau.Siv ntau zaus kom ua tiav cov txiaj ntsig xav tau.
4. Chlormequat

Chlormequat Chlormequat 1
Chlormequat kuj yog ib qho kev cog qoob loo uas nquag siv los ntawm cov neeg ua liaj ua teb.Nws kuj muaj Paclobutrazol.Nws tuaj yeem siv rau txau, soaking thiab hnav cov noob.Nws muaj cov txiaj ntsig zoo ntawm kev tswj kev loj hlob, kev txhawb paj, kev txhawb nqa txiv hmab txiv ntoo, kev tiv thaiv chaw nyob, tiv thaiv khaub thuas, Nws muaj cov teebmeem ntawm drought-resistant, ntsev-alkali tsis kam thiab txhawb pob ntseg tawm los.
Nta: Sib txawv ntawm Paclobutrazol, uas feem ntau yog siv rau hauv cov yub yub thiab theem tshiab kev loj hlob, Chlormequat feem ntau yog siv rau theem paj thiab txiv hmab txiv ntoo, thiab feem ntau siv rau cov qoob loo nrog lub sij hawm loj hlob luv.Txawm li cas los xij, kev siv tsis raug feem ntau ua rau cov qoob loo shrinkage.Tsis tas li ntawd, Chlormequat tuaj yeem siv nrog urea thiab acidic chiv, tab sis tsis tuaj yeem tov nrog alkaline chiv.Nws yog haum rau cov av nrog txaus fertility thiab kev loj hlob zoo.Nws yuav tsum tsis txhob siv rau cov av uas tsis muaj fertility thiab kev loj hlob tsis muaj zog.
