Qhov sib txawv hauv qhov cuam tshuam ntawm cov nroj tsuag cog retardants

Cog Retardants yog qhov tseem ceeb hauv cov txheej txheem ntawm cov qoob loo cultivation. Los ntawm kev tswj hwm kev loj hlob ntawm cov zaub ntsuab thiab kev ua me nyuam ntawm cov qoob loo, zoo dua zoo thiab siab dua tuaj yeem ua tiav. Kev loj hlob ntawm tsob nroj retardants feem ntau suav nrog Pacloburant, MepiTatat, VerbeTat, thiab lwm yam raws li kev sib tham tsis ntev los no, thiab cov naj npawb ntawm kev sau npe tau nce sai. Yog li, dab tsi yog qhov sib txawv ntawm pacloburazol, clofosbuver, mepiquat, cepormadionat, thiab prohexadionata calcium hauv kev siv ua lag luam? Tus kws sau ntawv yuav qhia lawv rau nej ib leeg!


(1) PREXEXADionE Calcium: nws yog hom tshiab ntawm cov nroj tsuag loj hlob retardant.

Nws cov yam ntxwv raug yog: Nyob rau tib lub sijhawm, nws tsis muaj kev cuam tshuam ntawm GA4 uas tswj cov paj tawg paj thiab cov nyom nyom.

Prohexadione calcium tau tsim tawm hauv Nyij Pooj uas tsim kev lag luam tshiab tsim los ntawm Kuibo Tshuaj Kev Lag Luam tsim los ntawm Kev Lag Luam Kev Lag Luam Tshiab, Ltd. Nws yog rau lub acylolyclohexanedione kev loj hlob retardant. Qhov kev tshawb pom ntawm Prohexadione calcium yog txawv los ntawm cov nroj tsuag kev loj hlob retardants xws li Quarda salts (mepormaum chloride) thiab triazoles (paclobutrazol, uniconazole). Nws tau qhib ib daim teb tshiab ntawm lig inhibition ntawm gibberellin biosynthesis.

Nws tau ua raws thiab siv dav hauv Tebchaws Europe thiab Tebchaws Asmeskas. Ntawm tam sim no, ProHexadionie calcium tau nyiam kev saib xyuas dav dav los ntawm cov tuam txhab hauv tsev. Qhov laj thawj tseem ceeb yog qhov uas piv nrog cov calcium retardants, Prohexadione Calcium tsis muaj kev sib hloov ntawm cov nroj tsuag, uas yog lub zog zoo dua. Nyob rau hauv lub neej yav tom ntej, nws yuav hloov triazole kev loj hlob retardants thiab muaj cov khoom thov sib txawv hauv teb, paj ntoo, paj, Suav cov tshuaj thiab cov qoob loo muaj nyiaj txiag.

(2) Pacloburanzol:
Ib tug inhibitor ntawm endogenous gibberellic acid hauv nroj tsuag. Nws muaj qhov cuam tshuam ntawm kev qeeb cog kev loj hlob, inhibiting qia vibreat, txhawb kev kev tiv thaiv cov paj sib txawv, thiab ua kom muaj txiaj ntsig zoo. Pacloburanka yog qhov tsim nyog rau cov qoob loo xws li mov, nplej, txiv ntoo txiv ntoo, thiab cov nyom, thiab muaj cov kev cuam tshuam tseem ceeb hauv kev tswj hwm kev loj hlob ntau dhau.

Kev phiv los ntawm Pacloburanzol: Kev siv ntau dhau tuaj yeem ua rau cov nroj tsuag qhuav, ua rau muaj kev puas tsuaj rau cov qoob loo, ua ntej cov yub, cov noob qeeb, cov noob tsis muaj tshwm sim tus nqi, cov noob uas tsis txaus ntseeg thiab lwm yam tsos mob.

(3) Uniconazole:
Nws tseem yog ib qho ua kom tsis muaj qhov sib tiv thaiv ntawm Gibberellins. Nws muaj cov haujlwm ntawm kev tswj hwm cov zaub ntsuab, tsis txaus siab rau cov nroj tsuag internodes, txhawb nqa tom qab Txij li thaum Uniconazole muaj cov pa roj carbon ob chav ua haujlwm, nws cov txiaj ntsig kev ua si yog 6 txog 10 zaug siab dua, thiab nws cov kev cuam tshuam rau cov qoob loo tom ntej yog tsuas yog 1 / 5 ntawm pacloburanol.

Kev phiv los ntawm Uniconazole: ntau dhau los yuav ua rau cog puas, witing, nplooj poob, txiv hmab txiv ntoo poob, thiab lig kom loj hlob. Ntxiv rau, nws daim ntawv thov nyob rau hauv cov noob ntoo ntawm cov zaub tuaj yeem cuam tshuam rau kev loj hlob ntawm cov noob. Nws tseem yog lom rau ntses thiab tsis haum rau siv nyob rau hauv ntses pas dej thiab lwm yam dej ua liaj ua teb.


(4) Mepiquat Chloride:
Nws yog ib qho inhibitor ntawm gibberellins. Nws tuaj yeem txhim kho cov khoom hluavtaws ntawm chlorophyll thiab ntxiv dag zog rau cov nroj tsuag. It can be absorbed through the leaves and roots of plants and transmitted to the whole plant, thereby inhibiting cell elongation and apical dominance. Nws kuj tseem tuaj yeem ua kom luv luv internodes thiab ua rau cov nroj tsuag cog. Nws tuaj yeem ncua kev loj hlob tuaj ntawm cov nroj tsuag, tiv thaiv kev loj hlob dhau los, thiab qeeb kab kaw. Mepiquat Chloride tuaj yeem txhim kho kev ruaj ntseg ntawm cov xov tooj ntawm tes ntawm tes thiab nce cog tsis kam. Piv nrog pacloburanzol thiab uniconazole, nws yog qhov me me thiab tsis muaj kev nyab xeeb, nrog kev nyab xeeb ntau dua. Nws tuaj yeem siv tau ntawm txhua theem ntawm cov qoob loo, txawm tias thaum lub caij nplooj ntoo thiab cov qoob loo ntawm cov qoob loo muaj kev nkag siab zoo heev, thiab muaj yeej tsis muaj kev phiv tsis zoo.

(5) Chlormequatat Chloride:Nws ua tiav cov nyhuv ntawm kev tswj kev loj hlob ntau dhau los ntawm inhibiting synthesis ntawm endogenous gibberelins. Chlormequatat Chloride muaj cov kev cai ua haujlwm ntawm kev cog qoob loo, kev txhim kho kev loj hlob thiab kev kho kom purination thiab cov txiv hmab txiv ntoo teeb tsa, thiab nce kom zoo nkauj. Kev ncua lub xov tooj ntawm tes elongation tau tshwm sim hauv cov nroj tsuag dwarfed, thicker stems, thiab luv dua workodes.

Tsis zoo li Pacloburanzol thiab Mepiquat Chloride, Paclobrazol feem ntau yog siv rau cov txiv laum huab xeeb, tab sis feem ntau tsis zoo rau lub caij nplooj zeeg thiab lub caij ntuj no qoob loo. Chlormaquatat Chloride feem ntau yog siv thaum lub caij ua paj thiab ntau zaus siv rau cov qoob loo nrog lub sijhawm kev loj hlob luv luv. Txawm li cas los xij, kev siv tsis raug ntawm Chlormequatat chloride feem ntau ua rau cov txiv ntoo shrinkage, thiab kev puas tsuaj yog qhov nyuaj kom raug. Mepiquat Chloride ntau dua, thiab kev puas tsuaj tuaj yeem ua kom muaj kev cuam tshuam los ntawm kev txau gibberellins lossis ywg dej kom nce fertility.
