Izaqathi zingalawulwa kusukela ekuqhakazeni ngokusebenzisa uhlobo lwe-malonylureaabalawuli bokukhula(ukuhlushwa okungu-0.1% – 0.5%) noma abalawuli bokukhula kwezitshalo njenge-gibberellin. Kuyadingeka ukukhetha uhlobo lomuthi olufanele, ukuhlushwa, kanye nokwazi isikhathi nendlela efanele yokufaka.
Izaqathi ziwuhlobo oluvamile lwemifino, olucebile ngezakhamzimba futhi oluthandwa kakhulu ngabantu. Kodwa-ke, ngesikhathi senqubo yokutshala, izaqathi zingase zibhekane nokubola, okuthinta isivuno kanye nekhwalithi. Ukuze balawule ngempumelelo ukubola kwezaqathi, abalimi bavame ukukhetha ukusebenzisa abalawuli bokukhula kwezitshalo.
I. Abalawuli Bokukhula Kwe-Maleic Hydrazide
Izilawuli zokukhula ze-hydrazide ze-Maleic zingenye yemithi esetshenziswa kakhulu ukulawula ukugoba kwezaqathi. Zilawula amazinga e-hormone emzimbeni wesitshalo, zivimbele ukunwebeka kwesiqu, ngaleyo ndlela zibambezele isikhathi sokugoba kwezaqathi. Indlela ethile yokusebenzisa yilena elandelayo: Ngesikhathi sokukhula kwezaqathi, ukufafaza izilawuli zokukhula ze-hydrazide ze-maleic ezingu-0.1% kuya ku-0.5% kungalawula ngempumelelo isimo sokugoba. Kodwa-ke, kubalulekile ukuqaphela lapho uzisebenzisa futhi ugweme ukusetshenziswa ngokweqile ukuvimbela ukukhula okungavamile kwezaqathi.
II. Abalawuli Bokukhula Kwezitshalo abanjengoAma-Gibberellins
Ngaphandle kwezindlela zokulawula ukukhula kohlobo lwe-malonylhydrazine, ama-gibberellin kanye nezinye izindlela zokulawula ukukhula kwezitshalo zingasetshenziswa futhi ukuvimbela ukubola kwe-carrot. Ama-gibberellin angakhuthaza ukukhula kwezitshalo ze-carrot ngenkathi evimbela ukunwebeka kweziqu, ngaleyo ndlela avimbele ukubola kwe-bolting. Uma uwasebenzisa, kubalulekile ukukhetha uhlobo lomuthi olufanele kanye nokuhlushwa ngokusekelwe esimweni sangempela, bese uqonda isikhathi nendlela efanele yokufaka. Ngokuvamile, ukufafaza ngesikhathi sokuqala sokukhula kwe-carrot noma ngaphambi kokubola kusebenza kangcono.
III. Ukubaluleka Kwezinyathelo Zokuphatha Eziphelele
Nakuba ukusetshenziswa kwabalawuli bokukhula kwezitshalo kungalawula ngempumelelo ukuhluma kwezaqathi, izinyathelo zokuphatha eziphelele zibaluleke ngokulinganayo. Abalimi kufanele bakhethe izinhlobo ezimelana kakhulu nokuhluma ukuze zitshalwe, futhi baqinise ukuphathwa kwensimu ngokugcina umswakama wenhlabathi kanye namazinga okushisa afanele. Ngaphezu kwalokho, ukususwa kwezinambuzane nezifo ngesikhathi esifanele nakho kungenye yezinyathelo ezibalulekile zokuvimbela ukuhluma kwezaqathi.
Ekuphetheni, ukulawula ukubola kwe-bolt kuma-carrot, kungasetshenziswa izilawuli zokukhula ezifana ne-malonylurea noma i-gibberellins. Kubalulekile ukunaka ukukhethwa kwemithi, ukuhlushwa kwayo, isikhathi sokusetshenziswa, kanye nezindlela zokusetshenziswa. Ngesikhathi esifanayo, ukuqinisa izinyathelo zokuphatha eziphelele nakho kuyindlela ebalulekile yokuvimbela ukubola kwe-bolt kuma-carrot. Ngokuphathwa kwesayensi kanye nokusetshenziswa kwemithi okunengqondo, abalimi bangakhuphula ngempumelelo isivuno kanye nekhwalithi yama-carrot.
