Ubuchwepheshe bokufaka isicelo kumango:Vimba ukukhula kwehlumela
Ukufakwa kwezimpande zomhlabathi: Uma ukuhluma kukamango kufinyelela ku-2cm ubude, ukusetshenziswa kuka-25%paclobutrazolimpushana emanzi endaweni eyindilinga yendawo yempande yesitshalo ngasinye sikamango esivuthiwe ingavimbela ngokuphumelelayo ukukhula kwamahlumela amasha kamango, inciphise ukusetshenziswa kwezakhi, ikhulise kakhulu inani lezimbali, ifinyeze ubude bendawo, umbala weqabunga elimnyama, ikhulise okuqukethwe kwe-chlorophyll, ikhulise ukoma kwamaqabunga, futhi ithuthukise ukumelana okubandayo kwezimbali. Khulisa izinga lokumisa izithelo futhi uthele kakhulu. Ukufakwa komhlabathi kunomphumela oqhubekayo wokuvimbela ngenxa yokumuncwa kwezimpande okuqhubekayo, futhi ukushintshashintsha okuguquguqukayo kokukhula kwamahlumela amasha kuncane. Kunomthelela omkhulu ekuvimbeleni ukukhula kwezihlahla zikamango ngonyaka wokuqala, kunomthelela omkhulu ovimbela ukukhula onyakeni wesibili, kanye nomphumela omaphakathi onyakeni wesithathu. Ukwelashwa ngethamo eliphezulu kwakusenokuvimbela okuqinile kumahlumela onyakeni wesithathu. Ukufakwa komhlabathi kulula ukukhiqiza into yokuvimbela ngokweqile, umphumela osalayo wohlelo mude, futhi unyaka wesibili kufanele umiswe.
Ukufafaza kwe-Foliar:Lapho amahlumela amasha ekhula abe ngu-30cm ubude, isikhathi sokuvimbela esisebenzayo sasingaba ngu-20d nge-1000-1500mg / L paclobutrazol, bese ukuvimbela kwakusesilinganisweni, futhi ukukhula kwamahlumela amasha kwashintsha kakhulu.
Indlela yokufaka isicelo se-Trunk:Esikhathini sokukhula noma isikhathi sokulala, i-paclobutrazol powder emanzi ixubene namanzi enkomishini encane, bese isetshenziswa emagatsheni angaphansi kwamagatsha amakhulu ngebhulashi elincane, inani lifana nelokusebenza kwenhlabathi.
Qaphela:Ukusetshenziswa kwe-paclobutrazol ezihlahleni zikamango kufanele kulawulwe ngokuqinile ngokuya ngendawo yendawo kanye nezinhlobo zemango, ukuze ugweme ukuvinjwa ngokweqile kokukhula kwesihlahla sepentshisi, i-paclobutrazol ayikwazi ukusetshenziswa unyaka nonyaka.
I-Paclobutrazol inomphumela osobala ezihlahleni zezithelo. Ukuhlolwa kokukhiqiza okukhulu kwenziwa ezihlahleni zikamango ezineminyaka engu-4-6 ubudala. Imiphumela yabonisa ukuthi ukuqhakaza kwezimbali kwakungaphambi kuka-12-75d ngaphambi kokulawula, futhi inani lezimbali likhulu, ukuqhakaza kwakuhlelekile, futhi isikhathi sokuvuna sasisengaphambili kakhulu ngo-14-59d, nokwanda okukhulu kwesivuno kanye nezinzuzo ezinhle zezomnotho.
I-Paclobutrazol iwubuthi obuphansi futhi isilawuli sokukhula kwezitshalo esisebenzayo esisetshenziswa kabanzi njengamanje. Ingavimbela i-biosynthesis ye-gibberellin ezitshalweni, ngaleyo ndlela ivimbele ukukhula kwezitshalo zezitshalo futhi ikhuthaze ukuqhakaza nezithelo.
Ukuzijwayeza kufakazele ukuthi izihlahla zikamango ezineminyaka engu-3 kuya kwengu-4, inhlabathi ngayinye enamagremu angu-6 yenani lokuhweba (isithako esisebenzayo 25%) sePaclobutrazol, ingavimbela ngokuphumelelayo ukukhula kwamagatsha omango futhi ikhuthaze ukuqhakaza. Ngo-September 1999, u-Tainong oneminyaka engu-3 ubudala oneminyaka engu-1 no-4 ubudala u-Aiwenmao no-Zihuamang baphathwa nge-6 g yenani lezentengiselwano paclobutrazol, okwandisa izinga lamacici ngo-80.7% kuya ku-100% uma kuqhathaniswa nokulawula (ngaphandle kwe-paclobutrazol). Indlela yokusebenzisa i-paclobutrazol ukuvula umsele ongashoni emgqeni wokuconsa womqhele wesihlahla, ukuncibilikisa i-paclobutrazol emanzini bese uyifaka ngokulinganayo emgodini bese uyimboza ngenhlabathi. Uma isimo sezulu somile phakathi nenyanga engu-1 ngemuva kokufakwa, amanzi kufanele acwiliswe kahle ukuze inhlabathi ihlale imanzi.
