Abalawuli bokukhula kwezitshalo bahlungwe ngezigaba zezibulala-zinambuzane, ezikhiqizwa ngokwenziwa noma ezikhishwe kuma-microorganism futhi zinemisebenzi efanayo noma efanayo nama-hormone ezitshalo angaphandle. Zilawula ukukhula kwezitshalo ngezindlela zamakhemikhali futhi zithinta ukukhula nokukhula kwezitshalo. Kungenye yentuthuko enkulu ku-physiology yezitshalo zanamuhla kanye nesayensi yezolimo, futhi isibe uphawu olubalulekile lwezinga lokuthuthukiswa kwesayensi yezolimo nobuchwepheshe. Ukuhluma kwembewu, ukuhluma kwezimpande, ukukhula, ukuqhakaza, ukuthela izithelo, ukuguga, ukuchitheka, ukulala kanye neminye imisebenzi ye-physiological, yonke imisebenzi yokuphila yezitshalo ayihlukaniswa nokubamba kwazo iqhaza.
Ama-hormone amahlanu amakhulu ezitshalo angaphandle: ama-gibberellin, ama-auxin, ama-cytokinins, ama-abscisic acid, kanye ne-ethylene. Eminyakeni yamuva nje, ama-brassinolides abekwe ohlwini lwesithupha futhi amukelwe yimakethe.
Ama-ejenti ezitshalo ayishumi aphezulu okukhiqiza nokusebenzisa:i-ethephon, i-gibberellic acid, i-paclobutrazol, i-chlorfenuron, i-thidiazuron, i-mepipenium,i-brassin,i-chlorophyll, i-indole acetic acid, kanye ne-flubenzamide.
Eminyakeni yamuva nje, inkampani igxile ezinhlotsheni zemithi yokulungisa izitshalo: i-procyclonic acid calcium, i-furfuraminopurine, i-silicon Fenghuan, i-coronatine, ama-antibiotic abangela i-S-inducing, njll.
Abalawuli bokukhula kwezitshalo bahlanganisa i-gibberellin, i-ethylene, i-cytokinin, i-abscisic acid kanye ne-brassin, njenge-brassin, okuwuhlobo olusha lomlawuli wokukhula kwezitshalo oluhlaza futhi olunobungani nemvelo, olungakhuthaza ukukhula kwemifino, amakhabe, izithelo nezinye izitshalo, lungathuthukisa ikhwalithi yesitshalo, lwandise isivuno sesitshalo, lwenze izitshalo zikhanye ngombala namaqabunga ajiyile. Ngesikhathi esifanayo, lungathuthukisa ukumelana nesomiso kanye nokumelana nokubanda kwezitshalo, futhi lunciphise izimpawu zezitshalo ezihlushwa yizifo nezinambuzane, umonakalo wezibulala-zinambuzane, umonakalo womanyolo kanye nomonakalo wokuqandisa.
Ukulungiswa okuhlanganisiwe kwamalungiselelo alungiswe izitshalo kukhula ngokushesha
Njengamanje, lolu hlobo lwenhlanganisela lunemakethe enkulu yokusetshenziswa, njenge: i-gibberellic acid + i-brassin lactone, i-gibberellic acid + i-auxin + i-cytokinin, i-ethephon + i-brassin lactone kanye nezinye izinto ezihlanganisiwe, Izinzuzo ezengeziwe zabalawuli bokukhula kwezitshalo ezinemiphumela ehlukahlukene.
Imakethe ihlelwa kancane kancane, futhi intwasahlobo iyeza
Uhulumeni Wezokuphatha Nokuphatha Imakethe Kahulumeni kanye ne-National Standardization Administration bavumile futhi bakhipha amazinga amaningi kazwelonke okuvikela izitshalo nezinto zezolimo, phakathi kwawo ukukhishwa kwe-GB/T37500-2019 ethi “Ukunqunywa Kwabalawuli Bokukhula Kwezitshalo Kumanyolo Nge-High Performance Liquid Chromatography” kuvumela ukuqapha Isenzo esingekho emthethweni sokwengeza abalawuli bokukhula kwezitshalo kumanyolo sinokusekelwa kobuchwepheshe. Ngokusho kwe-“Pesticide Management Regulations”, uma nje izibulala-zinambuzane zengezwa kumanyolo, imikhiqizo iyizibulala-zinambuzane futhi kufanele ibhaliswe, ikhiqizwe, isetshenziswe, isetshenziswe futhi iqondiswe ngokuhambisana nezibulala-zinambuzane. Uma isitifiketi sokubhalisa izibulala-zinambuzane singatholakali, siyizibulala-zinambuzane ezikhiqizwa ngaphandle kokuthola isitifiketi sokubhalisa izibulala-zinambuzane ngokomthetho, noma uhlobo lwesithako esisebenzayo esiqukethwe ku-pesticide alufani nesithako esisebenzayo esimakwe ilebula noma incwadi yemiyalelo yesibulala-zinambuzane, futhi kutholakala ukuthi siyizibulala-zinambuzane ezingamanga. Ukwengezwa kwamakhemikhali e-phyto njengesithako esifihliwe kuhlangana kancane kancane, ngoba izindleko zokungabi semthethweni ziya zikhuphuka. Emakethe, ezinye izinkampani nemikhiqizo engekho emthethweni futhi edlala indima encane ekugcineni izosuswa. Lolu lwandle oluluhlaza okwesibhakabhaka lokutshala nokuzivumelanisa nezimo luheha abantu bezolimo besimanje ukuthi bahlole, futhi intwasahlobo yakhe isifikile ngempela.
