Eminyakeni yamuva nje, kube nezithelo eziningi ezingakavuthwa ngesikhathi sonyaka, futhi ekuqaleni kwentwasahlobo, kuzovela ama-strawberry amasha nama-peaches emakethe. Lezi zithelo zivuthwa kanjani zingakavuthwa ngesikhathi sonyaka? Ngaphambilini, abantu babecabanga ukuthi lesi kwakuyisithelo esikhuliswe endlini yokugezela. Kodwa-ke, ngokuqhubeka nokuvezwa kwama-strawberry angenalutho, amagilebhisi angenambewu, kanye namakhabe agugile eminyakeni yamuva nje, abantu sebeqalile ukungabaza ukuthi lezi zithelo ezibonakala zinkulu futhi zintsha ezingakavuthwa ngesikhathi sonyaka zimnandi ngempela? Ingabe ziphephile ngempela?
Ukubonakala kwalezi zithelo ezibukeka ngendlela engavamile kwaheha ukunaka kwabantu ngokushesha. Ama-hormone nawo angene embonweni wabantu. Abanye abantu, ukuze banciphise umjikelezo wokukhula kwezitshalo futhi bathole inzuzo enkulu, basebenzisa ama-hormone ezithelweni nasemifino eminingi engaphandle kwesizini ukuze bavuthwe ngokushesha. Yingakho ezinye izithelo zibukeka zinhle kodwa zinambitheka kabi kakhulu.
Ukuziphatha kwabathengisi abangathembekile abafaka ama-hormone emifinweni nasezithelo kwenze abantu abaningi bangazithandi ama-hormone, kanti nomlawuli wokukhula kwezitshalo onenhlanhla naye akathandwa ngabantu ngenxa yemiphumela yawo efana nama-hormone. Ngakho-ke uyini ngempela umlawuli wokukhula kwezitshalo? Ingabe uhlobene nama-hormone? Uhlobo luni lobuhlobo olunalo? Okulandelayo, ake sixoxe ngokuthi uyini umlawuli wokukhula kwezitshalo nokuthi iyini imisebenzi yawo?
Umlawuli wokukhula kwezitshalo uyisithako sezinto eziphilayo (noma esikhishwe ngokwemvelo kuma-microorganisms) esinomthetho wokukhula nokuthuthukiswa ofana ne-hormone yezitshalo yemvelo. Kuyisithako sokwenziwa esisetshenziswa ekukhiqizweni kwezolimo ngemva kokuba abantu beqonde isakhiwo kanye nendlela yokusebenza kwe-hormone yezitshalo yemvelo, ukuze kulawulwe ngempumelelo inqubo yokukhula kwezitshalo, kufezwe inhloso yokuzinzisa isivuno nokwandisa isivuno, kuthuthukiswe ikhwalithi, futhi kuthuthukiswe ukumelana nezitshalo. Abalawuli bokukhula kwezitshalo abavamile bafaka i-DA-6, i-Forchlorfenuron, i-sodium nitrite, i-brassinol, i-gibberellin, njll.
Abalawuli bokukhula kwezitshalo banezindlela eziningi zokusebenzisa futhi bayahlukahluka phakathi kohlobo lwesitshalo kanye nesitshalo esiqondiwe. Isibonelo:
Lawula ukuhluma kanye nokungavuki; khuthaza ukuhluma kwezimpande; khuthaza ukunwebeka kwamaseli kanye nokuhlukana; lawula ukuhluma kwehlumela noma ukuhluma; lawula uhlobo lwesitshalo (ukuvimbela ukuhlala okufushane nokuqinile); lawula ukuqhakaza noma ubulili besilisa nabesifazane, dala izithelo ezingenabantwana; Vula izimbali nezithelo, lawula ukuwa kwezithelo; lawula ukuma noma isikhathi sokuvuthwa kwezithelo; thuthukisa ukumelana nokucindezeleka (ukumelana nezifo, ukumelana nesomiso, ukumelana nosawoti kanye nokumelana nokubanda); Thuthukisa ikhono lokumunca umanyolo; khulisa ushukela noma ushintshe i-asidi; thuthukisa ukunambitheka nombala; Thuthukisa ukukhiqizwa kwe-latex noma i-resin; ukususwa kwamaqabunga noma ukulinganisa (ukusiza ukuvunwa ngomshini); ukulondolozwa, njll.
Ngokusho kweMithethonqubo Yokuphathwa Kwezibulala-zinambuzane, abalawuli bokukhula kwezitshalo bangaphansi kwesigaba sokuphathwa kwezibulala-zinambuzane, futhi uhlelo lokubhalisa nokuphatha izibulala-zinambuzane kufanele lusetshenziswe ngokuhambisana nomthetho. Bonke abalawuli bokukhula kwezitshalo abakhiqizwa, abathengiswayo futhi abasetshenziswa eShayina kumele babhaliswe njengezibulala-zinambuzane. Uma sisebenzisa abalawuli bokukhula kwezitshalo, kufanele sibasebenzise ngokuhambisana nemiyalelo futhi sithathe izinyathelo ezinhle zokuvikela ukuvimbela ukuphepha kwabantu, imfuyo kanye namanzi okuphuza.
