Emehlweni abalimi abaningi, i-urea iwumanyolo osebenza emhlabeni wonke.Izitshalo azikhuli kahle, lahla enye i-urea;Amaqabunga ezitshalo aphuzile futhi enye i-urea iphonswe kuwo;Ngisho noma izitshalo zithela izithelo futhi umphumela we-fruiting awulungile kakhulu, engeza ngokushesha i-urea;Ngisho ne-urea isetshenziswa njengomanyolo we-foliar.
Uyini umsebenzi we-urea?Uma umsebenzi nenjongo ye-urea ingacacile, ingase iholele emizamweni ephindwe kabili futhi ihluleke ngisho nokufeza umphumela oyifunayo.Ezimweni ezimbi kakhulu, kungaba nomthelela ekukhuleni kwezilimo, okuholela ekuncishisweni kwezitshalo noma ngisho nokuhluleka kwezitshalo!
Wonke umuntu uyazi ukuthi i-urea ingumanyolo we-nitrogen onokuqukethwe okuphezulu kwe-nitrogen.Isici esibaluleke kakhulu esidingekayo ekukhuleni kwezitshalo umanyolo we-nitrogen.Ngakho-ke wonke umuntu ukholelwa ukuthi uma ukukhula kwezitshalo kungalungile kakhulu, kuzoswela umanyolo we-nitrogen.Empeleni, akunjalo.Uma wazi indima nokusebenza kahle komanyolo we-nitrogen, uzosebenzisa i-urea ngendlela efanele.
1: Izakhiwo ze-urea
I-Urea ingumanyolo obaluleke kakhulu futhi ungomunye womanyolo wenitrogen osetshenziswa kakhulu abalimi ezitshalweni.I-nitrogen equkethwe ku-urea ilinganiselwa ku-46%, okuyiyona ephezulu kunawo wonke ama-fertilizer aqinile.I-Urea ingumanyolo ongathathi hlangothi olungele inhlabathi ehlukahlukene kanye nanoma yisiphi isitshalo.Kulula ukuyigcina, ilungele ukuthuthwa, futhi inomonakalo omncane emhlabathini.Njengamanje iwumanyolo we-nitrogen osetshenziswa kakhulu ekukhiqizweni kwezolimo.
2: Umsebenzi nokusetshenziswa kwe-Urea
(1) I-Urea ingathuthukisa ukukhula kwezitshalo.Ingxenye ye-nitrogen ku-urea ingenye yezakhi ezibalulekile ekukhuleni nasekuthuthukeni kwezitshalo.Uma isitshalo singenawo umanyolo we-nitrogen, sizovela njengoba umbala wesitshalo ulula futhi amaqabunga amadala phansi aphenduka aphuzi;Iziqu zezitshalo zincane futhi zibuthakathaka;Amagatsha ambalwa noma amathila aholela ekugugeni ngaphambi kwesikhathi kwezitshalo;Uma kunokuntuleka komanyolo we-nitrogen ezihlahleni zezithelo, kungaholela ezikhunjeni zezithelo ezincane, ezimbalwa, eziwugqinsi neziqinile.
(2) I-Urea ingakhuthaza ukukhula kwamahlumela amasha ngesikhathi sokukhula kwezitshalo.Ngesikhathi sokukhula kwezitshalo, ukusebenzisa i-urea kungakhuthaza ukukhula kwamahlumela amasha ezitshalweni, ikakhulukazi izihlahla zezithelo.Ukusetshenziswa kwe-urea ezitshalweni kungakhuthaza okuqukethwe kwe-nitrogen emaqabunga ezitshalo, kusheshise ukukhula kwamahlumela amasha, futhi kuvimbele izimbali zezimbali.
(3) I-Urea, njengomanyolo we-foliar, ingafaka izitshalo ngomanyolo kuyilapho ibulala izinambuzane.Ukuncibilikisa i-urea newokuhlanza izingubo emanzini ahlanzekile bese uwafutha emaqabunga ezitshalo kungagcwalisa umanyolo ngokushesha futhi kubulale ezinye izinambuzane.Ukubulala izinambuzane ezithambile ezifana namabhungane eklabishi, ama-aphid, nezicabucabu ezibomvu kufinyelela ngaphezu kwama-90%.Njengomanyolo ongathathi hlangothi, i-urea imuncwa kalula amaqabunga futhi inomonakalo omncane kakhulu ezitshalweni.
