Izilawuli zokukhula kwezitshalo ziyizinhlobonhlobo ezihlukanisiwe zezibulala-zinambuzane, ezihlanganiswa ngokwenziwa noma ezikhishwe kumagciwane amancane futhi anemisebenzi efanayo noma efanayo namahomoni esitshalo endogenous.Zilawula ukukhula kwezitshalo ngamakhemikhali futhi zibe nomthelela ekukhuleni nasekuthuthukeni kwezilimo.Ingenye yentuthuko enkulu kusayensi yezitshalo zesimanje kanye nesayensi yezolimo, futhi isibe uphawu olubalulekile lwezinga lokuthuthuka kwesayensi yezolimo nobuchwepheshe.Ukuhluma kwembewu, ukuhluma kwezimpande, ukukhula, ukuqhakaza, ukuqhakaza, ukubola, ukuchithwa, ukulala kanye neminye imisebenzi yomzimba, yonke imisebenzi yokuphila yezitshalo ayinakuhlukaniswa nokubamba kwabo iqhaza.
Amahomoni amahlanu amakhulu ezitshalo endogenous: gibberellins, auxins, cytokinins, abscisic acids, ne-ethylene.Eminyakeni yakamuva, ama-brassinolides afakwe ohlwini njengesigaba sesithupha futhi amukelwe yimakethe.
Ama-ejenti ezitshalo aphezulu ayishumi okukhiqiza nokusebenzisa:i-ethephon, i-gibberellik acid, paclobutrazoli-chlorfenuron, i-thidiazuron, i-mepiperinium,ithusi,I-chlorophyll, i-indole acetic acid, ne-flubenzamide.
Eminyakeni yamuva, inkampani igxile ezinhlobonhlobo zama-agent okulungisa izitshalo: i-procyclonic acid calcium, i-furfuraminopurine, i-silicon Fenghuan, i-coronatine, i-S-inducing antibiotics, njll.
Izilawuli zokukhula kwezitshalo zihlanganisa i-gibberellin, i-ethylene, i-cytokinin, i-abscisic acid ne-brassin, njenge-brassin, okuwuhlobo olusha lokulawula ukukhula kwezitshalo eziluhlaza futhi ezinobungane, ezingakhuthaza ukukhula kwemifino, amakhabe, izithelo nezinye izitshalo , zingathuthukisa ikhwalithi yezitshalo, yandisa isivuno, yenza izitshalo zikhanye ngombala kanye namahlamvu aminyene.Ngesikhathi esifanayo, ingathuthukisa ukumelana nesomiso kanye nokumelana nokubandayo kwezitshalo, futhi ikhulule izimpawu zezitshalo ezihlushwa izifo nezinambuzane, ukulimala kwezibulala-zinambuzane, ukulimala kukamanyolo kanye nokulimala okuqandisayo.
Ukulungiswa okuhlanganisiwe kwamalungiselelo ashintshwe izitshalo kukhula ngokushesha
Njengamanje, lolu hlobo lwe-compound lunemakethe enkulu yesicelo, njenge: gibberellic acid + brassin lactone, gibberellic acid + auxin + cytokinin, ethephon + brassin lactone kanye namanye amalungiselelo ahlanganisiwe, Izinzuzo ezihambisanayo zokulawula ukukhula kwezitshalo ezinemiphumela ehlukahlukene.
Imakethe igcinwa kancane kancane, futhi intwasahlobo iyeza
I-State Administration of Market Supervision and Administration kanye ne-National Standardization Administration igunyaze futhi yakhipha izindinganiso kazwelonke eziningi zokuvikela izitshalo nezinto zokulima, phakathi kwazo ukukhululwa kwe-GB/T37500-2019 “Ukunqunywa Kwezilawuli Zokukhula Kwezitshalo Kumanyolo Ngokusebenza Okuphezulu. I-Liquid Chromatography” ivumela ukuqapha Isenzo esingekho emthethweni sokwengeza izilawuli zokukhula kwezitshalo kumanyolo sinokusekelwa kobuchwepheshe.Ngokusho kwe-"Pesticide Management Regulations", inqobo nje uma izibulala-zinambuzane zengezwa kumanyolo, imikhiqizo iyizibulala-zinambuzane futhi kufanele ibhaliswe, ikhiqizwe, isetshenziswe, isetshenziswe futhi iqondiswe ngokuhambisana nezibulala-zinambuzane.Uma isitifiketi sokubhaliswa kwesibulala-zinambuzane singatholakali, isibulala-zinambuzane esikhiqizwa ngaphandle kokuthola isitifiketi sokubhaliswa kwesibulala-zinambuzane ngokomthetho, noma uhlobo lwesithako esisebenzayo esiqukethwe kwisibulala-zinambuzane alufani nesithako esisebenzayo esimakwe kulebula noma imanuwali yeziqondiso zesibulala-zinambuzane. , futhi uzimisele ukuba isibulala-zinambuzane mbumbulu.Ukwengezwa kwama-phytochemicals njengesithako esifihliwe kuyaguquka kancane kancane, ngoba izindleko zokungabi semthethweni ziya ngokuya zikhuphuka.Emakethe, ezinye izinkampani nemikhiqizo engahlelekile futhi edlala indima encane ekugcineni izoqedwa.Lolu lwandle oluluhlaza okwesibhakabhaka lokutshala nokulungisa luheha abantu bezolimo besimanje ukuthi bahlole, futhi intwasahlobo yakhe isifikile ngempela.
