Ukusetyenziswa kwePaclobutrazol 25% WP kwiMango

Itekhnoloji yokusebenzisa imango:Nqanda ukukhula kwehlumela

Ukusetyenziswa kweengcambu zomhlaba: Xa ukuhluma kwemango kufikelela kwi-2cm ubude, ukusetyenziswa kwe-25%i-paclobutrazolUmgubo omanzi kwi-groove ye-ring zone yeengcambu zesityalo ngasinye semango esivuthiweyo unokuthintela ngempumelelo ukukhula kwamahlumela amatsha emango, unciphise ukusetyenziswa kwezondlo, unyuse kakhulu inani lamahlumela eentyatyambo, ufinyeze ubude bamaqhuma, umbala wamagqabi aluhlaza okwesibhakabhaka, unyuse umxholo we-chlorophyll, unyuse izinto ezomileyo zamagqabi, kwaye uphucule ukumelana nokubanda kwamahlumela eentyatyambo. Ukunyusa izinga lokubeka iziqhamo kunye nesivuno kakhulu. Ukusetyenziswa komhlaba kunesiphumo sokuthintela okuqhubekayo ngenxa yokufunxwa kweengcambu okuqhubekayo, kwaye ukutshintsha okunamandla kokukhula kwamahlumela amatsha kuncinci. Inesiphumo sokuthintela esikhulu ekukhuleni kwamahlumela amatsha emithi yemango kunyaka wokuqala, isiphumo sokuthintela esikhulu ekukhuleni kunyaka wesibini, kunye nesiphumo esiphakathi kunyaka wesithathu. Unyango oluphezulu lwalusenokuthintela okukhulu kumahlumela kunyaka wesithathu. Ukusetyenziswa komhlaba kulula ukuvelisa into yokuthintela kakhulu, isiphumo esiseleyo sokusetyenziswa side, kwaye unyaka wesibini kufuneka uyekwe.

Ukutshiza ngamagqabi:Xa amahlumela amatsha akhula afikelela kwi-30cm ubude, ixesha lokuthintela elisebenzayo lalimalunga neentsuku ezingama-20 nge-1000-1500mg /L paclobutrazol, kwaye emva koko ukuthintela kwaba phakathi, kwaye amandla okukhula kwamahlumela amatsha atshintshatshintsha kakhulu.

Indlela yokusebenzisa umboko:Ngexesha lokukhula okanye ixesha lokungasebenzi, umgubo we-paclobutrazol omanzi uxutywa namanzi kwikomityi encinci, uze usetyenziswe kumasebe angaphantsi kwamasebe aphambili ngebrashi encinci, ubungakanani bufana nobo bokusetyenziswa komhlaba.

Phawula:Ukusetyenziswa kwe-paclobutrazol kwimithi yemango kufuneka kulawulwe ngokungqongqo ngokwemeko-bume yendawo kunye neentlobo zemango, ukuze kuthintelwe ukuthintela ukukhula kwemithi yepesika, i-paclobutrazol ayinakusetyenziswa unyaka nonyaka.

I-Paclobutrazol inefuthe elicacileyo kwimithi yeziqhamo. Uvavanyo olukhulu lwemveliso lwenziwe kwimithi yemango eneminyaka eyi-4-6 ubudala. Iziphumo zibonise ukuba unyango ludubule iintyatyambo emva kweentsuku ezili-12-75 ngaphambi kwexesha lolawulo, kwaye inani leentyatyambo likhulu, iintyatyambo bezicwangcisiwe, kwaye ixesha lokuvuna nalo lidlule kakhulu emva kweentsuku ezili-14-59, kunye nokwanda okukhulu kwesivuno kunye neenzuzo ezilungileyo zoqoqosho.

I-Paclobutrazol sisithinteli esinobuthi obuphantsi kwaye silawula ukukhula kwezityalo esisetyenziswa kakhulu okwangoku. Ingathintela ukwenziwa kwe-gibberellin kwizityalo, ngaloo ndlela ithintele ukukhula kwezityalo kunye nokukhuthaza ukudubula kweziqhamo kunye neziqhamo.

Izenzo ziye zabonisa ukuba imithi yemango eneminyaka emi-3 ukuya kwemi-4 ubudala, umhlaba ngamnye one-6 grams yobungakanani borhwebo (isithako esisebenzayo esiyi-25%) sePaclobutrazol, inokuthintela ngempumelelo ukukhula kwamasebe emango kwaye ikhuthaze ukudubula kweentyatyambo. NgoSeptemba 1999, iTainong No. 1 eneminyaka emi-3 ubudala kunye ne-Aiwenmao eneminyaka emi-4 ubudala kunye neZihuamang banyangwa nge-6 g yobungakanani borhwebo be-paclobutrazol, nto leyo eyanyusa izinga lokulima ngama-80.7% ukuya kwi-100% xa kuthelekiswa nolawulo (ngaphandle kwe-paclobutrazol). Indlela yokusebenzisa i-paclobutrazol kukuvula umngxuma ongaphantsi kumgca wokuthontsiza wesithsaba somthi, unyibilikise i-paclobutrazol emanzini kwaye uyifake ngokulinganayo emngxunyeni kwaye uyigqume ngomhlaba. Ukuba imozulu yomile kwisithuba senyanga e-1 emva kokusetyenziswa, amanzi kufuneka afakwe emanzini ngokufanelekileyo ukuze umhlaba uhlale umanzi.
