Iminqathe ingalawulwa ekudubuleni ngokusebenzisa uhlobo lwe-malonylureaizilawuli zokukhula(ugxininiso lwe-0.1% - 0.5%) okanye izilawuli zokukhula kwezityalo ezifana ne-gibberellin. Kuyimfuneko ukuba ukhethe uhlobo olufanelekileyo lweziyobisi, ukugxininiswa, kunye nokulawula ixesha elichanekileyo lesicelo kunye nendlela.
Iminqathe luhlobo oluqhelekileyo lwemifuno, ityebile kwizondlo kwaye ithandwa kakhulu ngabantu. Nangona kunjalo, ngexesha lenkqubo yokulima, iminqathe inokufumana i-bolting, echaphazela isivuno kunye nomgangatho. Ukulawula ngokufanelekileyo i-bolting kwi-carrots, abalimi badla ngokukhetha ukusebenzisa izilawuli zokukhula kwezityalo.
I. I-Maleic Hydrazide Growth Regulators
Izilawuli zokukhula kwe-Maleic hydrazide lelinye lamachiza asetyenziswa rhoqo ekulawuleni ukubolithwa kweminqathe. Balawula amanqanaba ehomoni kumzimba wesityalo, banqande ukwanda kwesiqu, kwaye ngaloo ndlela balibazisa ixesha lokubolisa iminqathe. Indlela yesicelo esithile yile ilandelayo: Ngexesha lokukhula kweekherothi, ukutshiza i-0.1% ukuya kwi-0.5% yokulawula ukukhula kwe-maleic hydrazide inokulawula ngokufanelekileyo i-bolting phenomenon. Nangona kunjalo, kuyimfuneko ukuba uqaphele xa usebenzisa kwaye ugweme ukusetyenziswa ngokugqithiseleyo ukukhusela ukukhula okungaqhelekanga kweekherothi.
II. Ukukhula kwezityalo Regulators ezifanaIiGibberellins
Ngaphandle kwezilawuli zokukhula kohlobo lwe-malonylhydrazine, iigibberellins kunye nezinye izilawuli zokukhula kwezityalo nazo zingasetyenziselwa ukuthintela ukubolithwa kweminqathe. I-Gibberellins inokukhuthaza ukukhula kwezityalo ze-carrot ngelixa inqanda ukunyuswa kweziqu, ngaloo ndlela ikhusela ukwenzeka kwe-bolting. Xa uzisebenzisa, kuyimfuneko ukukhetha uhlobo olufanelekileyo lweziyobisi kunye nogxininiso olusekwe kwimeko eyiyo, kwaye ulawule ixesha elichanekileyo lesicelo kunye nendlela. Ngokuqhelekileyo, ukutshiza ngexesha lokuqala lokukhula kwe-karoti okanye ngaphambi kokuba i-bolting isebenze ngakumbi.
III. Ukubaluleka kwamanyathelo oLawulo oluBanzi
Nangona ukusetyenziswa kwezilawuli zokukhula kwezityalo kunokulawula ngokufanelekileyo ukuhluma kweminqathe, amanyathelo olawulo olubanzi abaluleke ngokulinganayo. Abalimi kufuneka bakhethe iintlobo ezikwaziyo ukuxhathisa ukuntshulela ukutyalwa, kwaye bomeleze ulawulo lwamasimi ngokugcina ukufuma komhlaba namaqondo obushushu afanelekileyo. Ukongeza, ukususwa kwangethuba kwezinambuzane kunye nezifo kukwayenye yeendlela eziphambili zokuthintela ukuhluma komnqathe.
Ekugqibeleni, ukulawula i-bolting kwi-carrots, izilawuli zokukhula ezifana ne-malonylurea okanye i-gibberellins zingasetyenziswa. Kubalulekile ukunikela ingqalelo ekukhethweni kwamachiza, ukugxininiswa kwawo, ixesha lokufaka isicelo, kunye neendlela zokusetyenziswa. Kwangaxeshanye, ukomeleza amanyathelo olawulo olubanzi kukwayindlela ebalulekileyo yokuthintela ukubolthiswa kweekherothi. Ngolawulo lwezenzululwazi kunye nokusetyenziswa kweziyobisi okufanelekileyo, abalimi banokunyusa ngokufanelekileyo isivuno kunye nomgangatho weekherothi.
