Iikaroti zingalawulwa ekubeni zidubule ngokusebenzisa uhlobo lwe-malonylureaabalawuli bokukhula(uxinzelelo 0.1% – 0.5%) okanye abalawuli bokukhula kwezityalo ezifana ne-gibberellin. Kuyimfuneko ukukhetha uhlobo olufanelekileyo lweyeza, uxinaniso, kunye nokukwazi ukusebenzisa ixesha kunye nendlela efanelekileyo.
Iikaroti luhlobo oluqhelekileyo lwemifuno, zizityebi kwizakhamzimba kwaye zithandwa kakhulu ngabantu. Nangona kunjalo, ngexesha lenkqubo yokulima, iikaroti zinokuchaphazeleka yi-bolting, nto leyo echaphazela isivuno kunye nomgangatho. Ukuze balawule ngempumelelo i-bolting kwiikaroti, abalimi badla ngokukhetha ukusebenzisa abalawuli bokukhula kwezityalo.
I. Abalawuli bokukhula kweMaleic Hydrazide
Izilawuli zokukhula kwe-hydrazide ye-Maleic ngomnye wamayeza asetyenziswa kakhulu ukulawula ukugoba kwe-carrot. Zilawula amanqanaba e-hormone emzimbeni wesityalo, zithintele ukunwebeka kwesiqu, ngaloo ndlela zilibazise ixesha lokugoba kwe-carrot. Indlela ethile yokusebenzisa yile ilandelayo: Ngexesha lokukhula kwe-carrot, ukutshiza i-0.1% ukuya kwi-0.5% yezilawuli zokukhula kwe-hydrazide ye-maleic zinokulawula ngempumelelo isiganeko sokugoba. Nangona kunjalo, kuyimfuneko ukuba uqaphele xa uzisebenzisa kwaye uphephe ukusetyenziswa kakhulu ukuthintela ukukhula okungaqhelekanga kwe-carrot.
II. Abalawuli bokukhula kwezityalo abanjengoIiGibberellins
Ngaphandle kwezixhobo zokulawula ukukhula kohlobo lwe-malonylhydrazine, ii-gibberellins kunye nezinye izixhobo zokulawula ukukhula kwezityalo nazo zingasetyenziselwa ukuthintela ukubola kwe-carrot. Ii-Gibberellins zinokukhuthaza ukukhula kwezityalo ze-carrot ngelixa zithintela ukwandiswa kweziqu, ngaloo ndlela zithintele ukwenzeka kwe-bolting. Xa uzisebenzisa, kuyimfuneko ukukhetha uhlobo olufanelekileyo lweyeza kunye noxinzelelo olusekelwe kwimeko yokwenyani, kwaye ube nolwazi ngexesha elifanelekileyo kunye nendlela yokusebenzisa. Ngokubanzi, ukutshiza ngexesha lokuqala lokukhula kwe-carrot okanye ngaphambi kokuba i-bolting isebenze ngakumbi.
III. Ukubaluleka kweMilinganiselo yoLawulo oluBanzi
Nangona ukusetyenziswa kwabalawuli bokukhula kwezityalo kunokulawula ngempumelelo ukuhluma kweekreyiti, amanyathelo olawulo olupheleleyo abaluleke ngokulinganayo. Abalimi kufuneka bakhethe iintlobo ezichasene kakhulu nokuhluma ukuze zityalwe, kwaye baqinise ulawulo lwentsimi ngokugcina umswakama womhlaba kunye namaqondo obushushu afanelekileyo. Ukongeza, ukususwa kwezinambuzane nezifo ngexesha elifanelekileyo kukwayenye yeendlela eziphambili zokuthintela ukuhluma kweekreyiti.
Ukuqukumbela, ukulawula ukubola kwe-bolt kwiikherothi, abalawuli bokukhula abanjenge-malonylurea okanye i-gibberellins bangasetyenziswa. Kubalulekile ukuqaphela ukukhethwa kwamayeza, ubuninzi bawo, ixesha lokusetyenziswa, kunye neendlela zokusetyenziswa. Kwangaxeshanye, ukuqinisa amanyathelo olawulo olupheleleyo kukwayindlela ebalulekileyo yokuthintela ukubola kwe-bolt kwiikherothi. Ngolawulo lwesayensi kunye nokusetyenziswa kwamayeza okufanelekileyo, abalimi banokunyusa ngempumelelo isivuno kunye nomgangatho weekherothi.
