Zeziphi iziLawuli zokuKhula kwezityalo ekufuneka ziSetyenziselwe ukunxitywa kwembewu ukukhuthaza ukuNtshula kweengcambu kunye nokuntshula?
Ukunxitywa kwembewu okujolise ekukhuthazeni ukuhluma kunye nokuntshula, sincoma ukusebenzisa i-Brassinolide, i-Gibberellic Acid (GA₃), kunye ne-Sodium Nitrophenolates. Ezi zilawuli zokukhula kwezityalo ziyayiphelisa ngokufanelekileyo imbewu, zikhulise izinga lokuntshula, kwaye zivuselele ukukhula kwenkqubo yeengcambu, okukhokelela ekukhuleni okufanayo nokomelela kwezithole.
1. I-Brassinolide
Isebenza ukukhuthaza ukuntshula kwembewu, ukukhawulezisa ukumiliselwa kweengcambu, kunye nokukhuthaza inkqubo yeengcambu ekhule kakuhle, lo gama ngaxeshanye ikhuthaza ukuxhathisa kwezithole kwingqele nembalela.
Indlela yeSicelo: Kwi-mu nganye (malunga ne-0.067 yeehektare) zomhlaba, xuba i-5-10 ml ye-0.01% ye-Brassinolide e-soluble liquid kunye ne-200-300 ml yamanzi okuxutywa. Hlanganisa ngokucokisekileyo esi sisombululo kunye nembewu-efana nengqolowa okanye umbona-ukuvumela ukuba zome emoyeni, uze uqhubeke nokuhlwayela.
Iziphumo:** Linyusa kakhulu izinga lokuvela; kukhokelela kwisixokelelwano seengcambu esiphuhlileyo kunye nokukhula okufanayo, okunamandla ngexesha lenqanaba lezithole.
2. I-Gibberellic Acid (GA3)
Iyakwazi ukwaphula i-dormancy yembewu, ivuselela ukunwebeka kwe-coleoptile, kunye nokukhuthaza ukuntshula. Ilungele ukusetyenziswa kunye nembewu endala okanye xa uhlwayela kwiindawo eziphantsi kobushushu.
Indlela yokuFaka: Kwizityalo ezifana nerayisi kunye nebhali, cwilisa imbewu kwisisombululo se-1 mg /kg GA3 kwiiyure ezi-6-12; kwiibhubhu zezambane, cwilisa kwisisombululo se-0.5-1 mg /kg imizuzu engama-30.
Qaphela: Ukugxila okugqithisileyo kunokukhokelela kwi-etiolation (i-stem elongation engaqhelekanga); ngoko ke, idosi kufuneka ilawulwe ngokungqongqo.
3. ISodium Nitrophenolates (Atonik)
Iphelisa ukulala, ikhuthaza ukukhula kweengcambu kunye nokomelela kwezithole, kwaye iphucula ukuntshula kwezithole. Isebenza kakhulu kwimbewu ephantsi koxinzelelo lobushushu obuphantsi.
Indlela yesicelo: Lungisa i-6000-fold dilution ye-1.8% isisombululo se-Atonik; cwilisa imbewu kwesi sisombululo kwiiyure ezili-12, zivumele ukuba zome emoyeni, kwaye emva koko zihlwayele.
Izinto eziluncedo:I-Sodium Nitrophenolates (i-Atonik) inokudityaniswa nezibulali ntsholongwane zokungunda, inika inzuzo ezimbini zokuthintelwa kwezifo kunye nokukhuthaza ukukhula.
1. I-Brassinolide
Isebenza ukukhuthaza ukuntshula kwembewu, ukukhawulezisa ukumiliselwa kweengcambu, kunye nokukhuthaza inkqubo yeengcambu ekhule kakuhle, lo gama ngaxeshanye ikhuthaza ukuxhathisa kwezithole kwingqele nembalela.
Indlela yeSicelo: Kwi-mu nganye (malunga ne-0.067 yeehektare) zomhlaba, xuba i-5-10 ml ye-0.01% ye-Brassinolide e-soluble liquid kunye ne-200-300 ml yamanzi okuxutywa. Hlanganisa ngokucokisekileyo esi sisombululo kunye nembewu-efana nengqolowa okanye umbona-ukuvumela ukuba zome emoyeni, uze uqhubeke nokuhlwayela.
Iziphumo:** Linyusa kakhulu izinga lokuvela; kukhokelela kwisixokelelwano seengcambu esiphuhlileyo kunye nokukhula okufanayo, okunamandla ngexesha lenqanaba lezithole.
2. I-Gibberellic Acid (GA3)
Iyakwazi ukwaphula i-dormancy yembewu, ivuselela ukunwebeka kwe-coleoptile, kunye nokukhuthaza ukuntshula. Ilungele ukusetyenziswa kunye nembewu endala okanye xa uhlwayela kwiindawo eziphantsi kobushushu.
Indlela yokuFaka: Kwizityalo ezifana nerayisi kunye nebhali, cwilisa imbewu kwisisombululo se-1 mg /kg GA3 kwiiyure ezi-6-12; kwiibhubhu zezambane, cwilisa kwisisombululo se-0.5-1 mg /kg imizuzu engama-30.
Qaphela: Ukugxila okugqithisileyo kunokukhokelela kwi-etiolation (i-stem elongation engaqhelekanga); ngoko ke, idosi kufuneka ilawulwe ngokungqongqo.
3. ISodium Nitrophenolates (Atonik)
Iphelisa ukulala, ikhuthaza ukukhula kweengcambu kunye nokomelela kwezithole, kwaye iphucula ukuntshula kwezithole. Isebenza kakhulu kwimbewu ephantsi koxinzelelo lobushushu obuphantsi.
Indlela yesicelo: Lungisa i-6000-fold dilution ye-1.8% isisombululo se-Atonik; cwilisa imbewu kwesi sisombululo kwiiyure ezili-12, zivumele ukuba zome emoyeni, kwaye emva koko zihlwayele.
Izinto eziluncedo:I-Sodium Nitrophenolates (i-Atonik) inokudityaniswa nezibulali ntsholongwane zokungunda, inika inzuzo ezimbini zokuthintelwa kwezifo kunye nokukhuthaza ukukhula.
