Abalawuli bokukhula kwezityalo luhlobo oluthile lwezibulali zinambuzane, ezenziwe ngokwenziwa okanye ezikhutshwa kwiintsholongwane kwaye zinemisebenzi efanayo okanye efanayo neehomoni zezityalo ezihlala zikho. Zilawula ukukhula kwezityalo ngeendlela zeekhemikhali kwaye zichaphazela ukukhula nophuhliso lwezityalo. Lulunye lwezona nkqubela phambili ziphambili kwi-physiology yezityalo zanamhlanje kunye nesayensi yezolimo, kwaye lube luphawu olubalulekileyo lophuhliso lwesayensi yezolimo kunye netekhnoloji. Ukuhluma kwembewu, ukuhluma iingcambu, ukukhula, ukudubula iintyatyambo, ukuhluma, ukuguga, ukubola, ukulala kunye neminye imisebenzi ye-physiological, yonke imisebenzi yobomi bezityalo ayinakwahlulwa kukuthatha inxaxheba kwazo.
Iihomoni ezintlanu eziphambili zezityalo eziphuma emzimbeni: ii-gibberellins, ii-auxins, ii-cytokinins, ii-abscisic acids, kunye ne-ethylene. Kwiminyaka yakutshanje, ii-brassinolides zidweliswe njengodidi lwesithandathu kwaye zamkelwe yimarike.
Iiarhente zezityalo ezilishumi eziphambili zemveliso kunye nokusetyenziswa:i-ethephon, i-gibberellic acid, i-paclobutrazol, i-chlorfenuron, i-thidiazuron, i-mepipenium,ibrassin,i-chlorophyll, i-indole acetic acid, kunye ne-flubenzamide.
Kwiminyaka yakutshanje, inkampani igxile kwiintlobo ngeentlobo zeearhente zokulungisa izityalo: i-procyclonic acid calcium, i-furfuraminopurine, i-silicon Fenghuan, i-coronatine, ii-antibiotics ezibangela i-S-inducing, njl.
Abalawuli bokukhula kwezityalo baquka i-gibberellin, i-ethylene, i-cytokinin, i-abscisic acid kunye ne-brassin, efana ne-brassin, oluluhlobo olutsha lolawulo lokukhula kwezityalo oluluhlaza nolunobuhlobo nokusingqongileyo, olunokukhuthaza ukukhula kwemifuno, ii-melon, iziqhamo kunye nezinye izityalo, lunokuphucula umgangatho wesityalo, lunyuse isivuno sesityalo, lwenze izityalo zikhanye ngombala kunye namagqabi atyebileyo. Kwangaxeshanye, lunokuphucula ukumelana nembalela kunye nokumelana nokubanda kwezityalo, kwaye lunciphise iimpawu zezityalo ezithwaxwa zizifo kunye nezinambuzane, umonakalo wezinambuzane, umonakalo we-fertilizer kunye nomonakalo wokuqandisa.
Ukulungiswa okuxutyiweyo kwamalungiselelo ahlengahlengiswe zizityalo kukhula ngokukhawuleza
Okwangoku, olu hlobo lwekhompawundi lunemarike enkulu yokusetyenziswa, efana ne: i-gibberellic acid + i-brassin lactone, i-gibberellic acid + i-auxin + i-cytokinin, i-ethephon + i-brassin lactone kunye nezinye izinto ezilungiselelweyo, Iingenelo ezongezelelweyo zabalawuli bokukhula kwezityalo ezineziphumo ezahlukeneyo.
Imakethi ibekwa emgangathweni kancinci kancinci, kwaye intwasahlobo iyeza
Ulawulo lweSizwe loLawulo lweMarike kunye noLawulo lweSizwe oluMiselweyo luvumile kwaye lukhuphe inani lemigangatho yesizwe yokukhuselwa kwezityalo kunye nezixhobo zezolimo, phakathi kwazo ukukhutshwa kwe-GB/T37500-2019 ethi “Ukumiselwa koLawulo loKhula kweZityalo kwiZichumisi yi-High Performance Liquid Chromatography” kuvumela ukujonga Isenzo esingekho mthethweni sokongeza abalawuli bokukhula kwezityalo kwizichumisi sinenkxaso yobugcisa. Ngokwe-“Pesticide Management Regulations”, lo gama nje izibulali-zinambuzane zongezwa kwizichumisi, iimveliso zizibulali-zinambuzane kwaye kufuneka zibhaliswe, ziveliswe, zisetyenziswe, zisetyenziswe kwaye zijongwe ngokuhambelana nezibulali-zinambuzane. Ukuba isatifikethi sobhaliso lwezibulali-zinambuzane asifumaneki, sisibulali-zinambuzane esiveliswa ngaphandle kokufumana isatifikethi sobhaliso lwezibulali-zinambuzane ngokomthetho, okanye uhlobo lwesithako esisebenzayo esikwisibulali-zinambuzane alufani nesithako esisebenzayo esiphawulwe kwileyibhile okanye kwincwadi yemiyalelo yesibulali-zinambuzane, kwaye sifunyaniswa ukuba sisibulali-zinambuzane sobuxoki. Ukongezwa kwee-phytochemicals njengesithako esifihliweyo kuyatshintsha kancinci kancinci, kuba iindleko zokungekho mthethweni ziya ziphakama ngakumbi nangakumbi. Kwimarike, ezinye iinkampani kunye neemveliso ezingekho sesikweni kwaye ezidlala indima encinci ziya kupheliswa ekugqibeleni. Olu lwandle luluhlaza okwesibhakabhaka lokutyala nokulungelelanisa izinto lutsala abantu bezolimo banamhlanje ukuba bahlole, kwaye intwasahlobo yakhe ifikile ngokwenene.
