I-Paclobutrazol ngokuvamile iyimpushana, engamuncwa esihlahleni ngezimpande, iziqu namaqabunga ezihlahla zezithelo ngaphansi kwesenzo samanzi, futhi kufanele isetshenziswe ngesikhathi sokukhula.Ngokuvamile kunezindlela ezimbili: ukusabalalisa umhlabathi kanye nokufafaza ngamahlamvu.
1. I-paclobutrazol engcwatshwe
Isikhathi esihle kakhulu lapho ihlumela lesibili lidubula cishe ngo-3-5 cm (lapho okuphuzi kuba luhlaza noma ngaphambi kokuluhlaza okukhanyayo).Ngokusho kobukhulu bomqhele, izinhlobo ezahlukene, nenhlabathi ehlukene, amanani ahlukene we-paclobutrazol asetshenziswa.
Ngokuvamile, inani lempahla ye-paclobutrazol lisetshenziswa imitha yesikwele yomqhele we-6-9 g, umsele noma umsele wendandatho uvulwa ngo-30-40 cm ngaphakathi komugqa wokudonsa noma u-60-70 cm ukusuka ekhanda lesihlahla, futhi umbozwe inhlabathi. ngemva kokuchelela.Uma isimo sezulu somile, Vala inhlabathi emva kokunisela okufanele.
Ukusetshenziswa kwe-paclobutrazol akufanele kusheshe kakhulu noma kuphuze kakhulu.Isikhathi esiqondile sihlobene nezinhlobonhlobo.Ukushesha kakhulu kuzoholela kalula kumahlumela amafushane kanye nokukhubazeka;sekwephuzile kakhulu, amahlumela esibili azothunyelwa ngaphambi kokuba amahlumela esithathu abe luhlaza ngokuphelele..
Inhlabathi ehlukene izophinde ithinte ukusetshenziswa kwe-paclobutrazol.Ngokuvamile, inhlabathi enesihlabathi inomphumela ongcono wokungcwaba kunenhlabathi yobumba.Kunconywa ukusebenzisa i-paclobutrazol kwezinye izinsimu zezithelo ezine-viscosity ephezulu yenhlabathi.
2. Ukufafaza nge-Foliar paclobutrazol ukulawula amahlumela
Isifutho se-paclobutrazol foliar sinomphumela othambile kuneminye imithi, futhi singadambisa ngempumelelo umonakalo esihlahleni ngesikhathi sokulawula ihlumela.Ngokuvamile, lapho amaqabunga ephenduka aluhlaza futhi engavuthiwe ngokwanele, sebenzisa i-paclobutrazol 15% i-powder emanzi okokuqala mayelana nezikhathi ze-600, futhi kancane kancane ukwandisa inani le-paclobutrazol 15% i-powder emanzi okwesibili.Lawula ukudubula kanye njalo - ezinsukwini eziyi-10.Ngemuva kokulawula amahlumela izikhathi ezi-1-2, amahlumela aqala ukuvuthwa.Qaphela ukuthi amahlumela awavuthwa ngokugcwele, ngokuvamile awafaki i-ethephon, ngaphandle kwalokho kulula ukubangela ukuwa kwamaqabunga.
Lapho amaqabunga ephenduka abe luhlaza, abanye abalimi bezithelo basebenzisa i-paclobutrazol ekulawuleni amahlumela okuqala.Umthamo ungamagremu angu-1400 no-450 kg wamanzi.Ukulawulwa kwesibili kwamahlumela ngokuyisisekelo kufana nokuqala.Umthamo uzoncishiswa kamuva uze ufinyelele ku-400. Nge-250 ml ye-ethephon.Lapho kuqala ukulawula amahlumela, isimo esivamile ukulawula kanye njalo ezinsukwini eziyisikhombisa, kodwa imigomo yelanga noma ezinye izici kufanele zicatshangelwe.Ngemva kokulawulwa ukuzinza, kungalawulwa kanye njalo ezinsukwini eziyishumi.
