Yini i-retardants yokukhula kwezitshalo? Izitshalo zokukhula kwezitshalo ziyisigaba sezinto zamakhemikhali ezivimbela ukukhula kwezitshalo, ukusunduza kanye nentuthuko futhi kukhuthaze ukunqwabelana okuphezulu. Ukukhula kokukhula kwezitshalo kuvame ukusetshenziswa kwezolimo kanye ne-horticulture ukulawula ukukhula kwezitshalo namanani entuthuko, kuqinisekisa ikhwalithi kanye nesivuno sezilimo noma izitshalo zasengadini.

Ekutshalweni kwezilimo ze-horticultural, kusetshenziswa izinhlobonhlobo zama-bakeli okukhula kwezitshalo, kudlula izinhlobo ezingama-40. Isibonelo, abagqugquzeli bokukhula kwezitshalo kufaka phakathi i-gibberellic acid (GA3), i-naphthyl acetic acid (NEA), i-Ibaa acetic acid (IBA), i-IBA), ne-IBA), kanye ne-2,4-D; Ukukhula kokukhula kwesitshalo kufaka phakathi i-ascosic acid

Ukukhula kokukhula kwezitshalo kubalulekile kwinqubo yokutshala izivumo. Ngokulawula ukukhula kwemifino nokukhula kokuzala kwezilimo, ikhwalithi engcono nesivuno esiphakeme singatholakala. Izitshalo zokukhula kwezitshalo zivame ukufaka i-paclobutrazol, Clofosbuvir, Mepiquat, Chlorecret

Inhlanganisela ye-diethelyl amiethyl hexanogen phosphate ingakhuthaza ngempumelelo ukukhula kwezitshalo nokutshala izithombo, ithuthukise izinga lokugcina izithelo, futhi lithuthukise ukumelana kwezithelo kwezilimo. Le ndlela yokusebenzisa ehlanganisiwe ithuthukisa isivuno nekhwalithi yezilimo.
