Kev siv technology ntawm mango:Inhibit tua kev loj hlob
Kev siv av hauv paus: Thaum mango germination ncav cuag 2cm ntev, daim ntawv thov ntawm 25%paclobutrazolwettable hmoov nyob rau hauv lub nplhaib zawj ntawm lub hauv paus cheeb tsam ntawm txhua tus txiv nkhaus taw paub tab tuaj yeem cuam tshuam qhov kev loj hlob ntawm cov txiv nkhaus taw tshiab, txo cov khoom noj khoom haus, ua kom cov paj buds, txo qhov ntev ntawm cov nplooj, tsaus ntsuab nplooj xim, nce chlorophyll cov ntsiab lus. , nce nplooj qhuav teeb meem, thiab txhim kho qhov txias tsis kam ntawm paj buds. Ua kom cov txiv hmab txiv ntoo nqis thiab tawm los ntau heev. Daim ntawv thov av muaj qhov cuam tshuam tsis tu ncua vim kev nqus cov hauv paus txuas ntxiv, thiab qhov hloov pauv hloov pauv ntawm kev loj hlob tshiab yog me me. Nws muaj cov nyhuv inhibitory tseem ceeb ntawm kev loj hlob tshiab ntawm tsob ntoo txiv nkhaus taw hauv thawj xyoo, muaj kev cuam tshuam ntau dua rau kev loj hlob hauv xyoo thib ob, thiab cov nyhuv nruab nrab hauv xyoo thib peb. Kev kho tshuaj ntau tseem muaj zog inhibition ntawm tua nyob rau hauv peb lub xyoos. Daim ntawv thov av yog ib qho yooj yim los tsim ntau yam inhibition tshwm sim, cov nyhuv residual ntawm daim ntawv thov yog ntev, thiab xyoo thib ob yuav tsum tau nres.
Foliar txau:Thaum cov tua tshiab loj hlob mus txog 30cm ntev, lub sijhawm inhibition zoo yog li 20d nrog 1000-1500mg / L paclobutrazol, thiab tom qab ntawd qhov inhibition yog nruab nrab, thiab kev loj hlob ntawm cov tua tshiab hloov pauv zoo heev.
Txoj kev siv lub cev:Thaum lub caij loj hlob lossis lub sijhawm dormant, paclobutrazol wettable hmoov yog tov nrog dej nyob rau hauv ib lub khob me me, thiab tom qab ntawd siv rau ntawm cov ceg hauv qab cov ceg tseem ceeb nrog txhuam me me, tus nqi yog tib yam li daim ntawv thov av.
Nco tseg:Kev siv paclobutrazol hauv cov ntoo txiv nkhaus taw yuav tsum tau tswj nruj me ntsis raws li thaj chaw ib puag ncig thiab cov txiv nkhaus taw, yog li kom tsis txhob cuam tshuam ntau dhau ntawm kev loj hlob ntawm txiv duaj ntoo, paclobutrazol tsis tuaj yeem siv txhua xyoo.
Paclobutrazol muaj cov txiaj ntsig zoo rau cov ntoo txiv ntoo. Kev sim ntau lawm tau ua tiav ntawm cov ntoo txiv nkhaus taw uas muaj hnub nyoog 4-6 xyoo. Cov txiaj ntsig tau pom tias kev kho mob paj yog 12-75d ua ntej tshaj li kev tswj hwm, thiab cov paj tau loj, lub paj tau zoo, thiab lub sijhawm sau qoob loo kuj tseem ceeb ua ntej los ntawm 14-59d, nrog rau kev nce ntxiv ntawm cov qoob loo thiab zoo. nyiaj txiag pab.
Paclobutrazol yog cov tshuaj toxicity tsawg thiab muaj txiaj ntsig zoo ntawm cov nroj tsuag kev loj hlob regulator dav siv tam sim no. Nws tuaj yeem inhibit biosynthesis ntawm gibberellin hauv cov nroj tsuag, yog li inhibiting cov nroj tsuag kev loj hlob thiab txhawb kev paj thiab txiv hmab txiv ntoo.
Kev xyaum tau ua pov thawj tias 3 mus rau 4 xyoo txiv nkhaus taw ntoo, txhua cov av nrog 6 gram ntawm kev lag luam (cov khoom muaj txiaj ntsig 25%) ntawm Paclobutrazol, tuaj yeem cuam tshuam kev loj hlob ntawm mango ceg thiab txhawb kev tawg paj. Thaum lub Cuaj Hlis 1999, 3 xyoos Tainong No. 1 thiab 4 xyoos Aiwenmao thiab Zihuamang tau kho nrog 6 g ntawm cov khoom lag luam ntawm paclobutrazol, uas nce pob ntseg ntawm 80.7% mus rau 100% piv nrog kev tswj hwm (tsis muaj paclobutrazol). Cov txheej txheem ntawm kev thov paclobutrazol yog qhib lub qhov dej ntiav hauv txoj kab drip ntawm tsob ntoo ntoo, yaj paclobutrazol hauv dej thiab sib npaug rau hauv qhov dej thiab npog nrog av. Yog tias huab cua qhuav hauv 1 lub hlis tom qab thov, dej yuav tsum tau tsau kom zoo kom cov av noo.
