Ubuchwepheshe bokusebenzisa umango:Vimbela ukukhula kwehlumela
Ukusetshenziswa kwezimpande zenhlabathi: Uma ukuhluma kwemango kufinyelela ku-2cm ubude, ukusetshenziswa kuka-25%i-paclobutrazolImpuphu emanzi emiseleni yendandatho yendawo yezimpande zesitshalo ngasinye sikamango esivuthiwe ingavimbela ngempumelelo ukukhula kwamahlumela amasha kamango, inciphise ukusetshenziswa kwezakhamzimba, ikhuphule kakhulu inani lamahlumela ezimbali, ifinyeze ubude bamaqhubu, umbala wamaqabunga aluhlaza okotshani, ikhuphule okuqukethwe yi-chlorophyll, ikhuphule izinto ezomile zamaqabunga, futhi ithuthukise ukumelana nokubanda kwamahlumela ezimbali. Yandisa izinga lokubeka izithelo futhi ikhiqize kakhulu. Ukusetshenziswa kwenhlabathi kunomphumela wokuvimbela okuqhubekayo ngenxa yokumuncwa kwezimpande okuqhubekayo, futhi ukushintshashintsha okunamandla kokukhula kwamahlumela amasha kuncane. Kunomphumela omkhulu wokuvimbela ekukhuleni kwamahlumela amasha ezihlahla zikamango ngonyaka wokuqala, umphumela omkhulu wokuvimbela ekukhuleni ngonyaka wesibili, kanye nomphumela olinganiselayo ngonyaka wesithathu. Ukwelashwa ngomthamo ophezulu kwakusenokuvimbela okukhulu emahlumela ngonyaka wesithathu. Ukusetshenziswa kwenhlabathi kulula ukukhiqiza into yokuvimbela ngokweqile, umphumela osele wokusetshenziswa mude, futhi unyaka wesibili kufanele umiswe.
Ukufutha ngamahlamvu:Lapho amahlumela amasha ekhula aze abe ngu-30cm ubude, isikhathi sokuvinjelwa esisebenzayo sasicishe sibe yizinsuku ezingu-20 nge-paclobutrazol engu-1000-1500mg /L, bese kuthi ukuvimbela kube okulinganiselwe, futhi amandla okukhula kwamahlumela amasha ashintshashintsha kakhulu.
Indlela yokufaka isiqu:Ngesikhathi sokukhula noma isikhathi sokulala, i-paclobutrazol wettable powder ixutshwa namanzi enkomishini encane, bese ifakwa emagatsheni angaphansi kwamagatsha amakhulu ngebhulashi elincane, inani lifana nelokusetshenziswa kwenhlabathi.
Qaphela:Ukusetshenziswa kwe-paclobutrazol ezihlahleni zemango kufanele kulawulwe ngokuqinile ngokwendawo kanye nezinhlobo zemango, ukuze kugwenywe ukuvinjelwa ngokweqile kokukhula kwesihlahla samapentshisi, i-paclobutrazol ayikwazi ukusetshenziswa unyaka nonyaka.
I-Paclobutrazol inethonya elisobala ezihlahleni zezithelo. Ukuhlolwa kokukhiqiza okukhulu kwenziwa ezihlahleni zemango ezineminyaka engu-4-6 ubudala. Imiphumela ibonise ukuthi ukwelashwa kuqhakaza izinsuku ezingu-12-75 ngaphambi kokulawula, futhi inani lezimbali likhulu, ukuqhakaza kwakuhlelekile, kanti isikhathi sokuvuna naso sasingaphambi kwesikhathi kakhulu ngezinsuku ezingu-14-59, kanye nokwanda okukhulu kwesivuno kanye nezinzuzo ezinhle zomnotho.
I-Paclobutrazol iyisilawuli sokukhula kwezitshalo esinobuthi obuphansi futhi esisebenzayo esisetshenziswa kabanzi njengamanje. Ingavimbela ukwenziwa kwe-gibberellin ezitshalweni, ngaleyo ndlela ivimbele ukukhula kwezitshalo ezimilayo futhi ikhuthaze ukuqhakaza kwezimbali nezithelo.
Umkhuba ubonise ukuthi izihlahla zemango ezineminyaka emi-3 kuya kwemi-4 ubudala, inhlabathi ngayinye enamagremu ayi-6 enani lokuthengisa (isithako esisebenzayo esingu-25%) se-Paclobutrazol, ingavimbela ngempumelelo ukukhula kwamagatsha emango futhi ikhuthaze ukuqhakaza kwezimbali. NgoSepthemba 1999, i-Tainong No. 1 eneminyaka emi-3 ubudala kanye ne-Aiwenmao eneminyaka emi-4 ubudala kanye ne-Zihuamang baphathwa nge-paclobutrazol engamagremu ayi-6 enani lokuthengisa, okwakhulisa izinga lokulima ngo-80.7% kuya ku-100% uma kuqhathaniswa nokulawula (ngaphandle kwe-paclobutrazol). Indlela yokusebenzisa i-paclobutrazol ukuvula umsele ongajulile emgqeni wokuconsa wesihlahla, uncibilikise i-paclobutrazol emanzini bese uyifaka ngokulinganayo emseleni bese uyimboza ngenhlabathi. Uma isimo sezulu somile zingakapheli inyanga eyodwa ngemuva kokufaka, amanzi kufanele acwiliswe kahle ukuze inhlabathi ihlale imanzi.
