Iindaba

Emehlweni amafama amaninzi, iurea sisichumisi sendalo yonke.Izityalo azikhuli kakuhle, yilahleni iurea;Amagqabi ezityalo ajike atyheli kwaye enye iurea igalelwe kuwo;Nangona izityalo zihluma kwaye umphumo we-fruiting awufanelekanga kakhulu, ngokukhawuleza yongeza i-urea;Nkqu neurea isetyenziswa njengesichumiso samagqabi.

Yintoni umsebenzi we-urea?Ukuba umsebenzi kunye nenjongo ye-urea ayicacanga, kunokukhokelela kwimigudu ephindwe kabini kwaye ingaphumeleli ukuphumeza umphumo oyifunayo.Kwiimeko ezimandundu, kunokuchaphazela ukukhula kwezityalo, okukhokelela ekuncitshisweni kwesityalo okanye ukusilela kwesityalo!
Wonke umntu uyazi ukuba i-urea sisichumisi se-nitrogen esinomxholo ophezulu we-nitrogen.Eyona nto ibalulekileyo efunekayo ekukhuleni kwesityalo sisichumiso senitrogen.Ke wonke umntu ukholelwa ukuba ukuba ukukhula kwesityalo akulunganga kakhulu, ngokuqinisekileyo kuya kuswela isichumiso senitrogen.Enyanisweni, oku akunjalo.Ukuba uyayazi indima kunye nokusebenza kakuhle kwesichumiso se-nitrogen, uya kwenza ukusetyenziswa ngokufanelekileyo kwe-urea.
1: Iipropati ze-urea
I-Urea sisichumiso esibaluleke kakhulu kwaye sesinye sezona zichumiso zenitrogen eziqhelekileyo ezisetyenziswa ngamafama kwizityalo.Isiqulatho senitrogen kwi urea simalunga ne 46%, eyona iphezulu kuzo zonke izichumisi eziqinileyo.I-Urea sisichumisi esingathathi hlangothi esilungele imihlaba eyahlukeneyo kunye naso nasiphi na isityalo.Kulula ukuyigcina, ilungele ukuthuthwa, kwaye inomonakalo omncinci emhlabeni.Okwangoku isesona sichumiso senitrogen esisetyenziswa kakhulu kwimveliso yezolimo.
2: Umsebenzi kunye nokusetyenziswa kweUrea
(1) IUrea inokukhuthaza ukukhula kwesityalo.I-nitrogen element kwi-urea sesinye sezondlo eziyimfuneko ekukhuleni nasekuphuhliseni isityalo.Ukuba isityalo asinaso isichumiso senitrogen, siya kubonakala njengoko umbala wesityalo ukhaphukhaphu kwaye amagqabi amadala kwisiseko ajika abe tyheli;Izikhondo zezityalo zibhityile kwaye zibuthathaka;Amasebe ambalwa okanye iithafa zokuhlakula zikhokelela ekubeni izityalo ziguge kwangethuba;Ukuba kukho ukunqongophala kwesichumiso senitrogen kwimithi yeziqhamo, kunokukhokelela kwizikhumba zeziqhamo ezincinci, ezimbalwa, ezishinyeneyo neziqinileyo.
(2) I-Urea inokukhuthaza ukukhula kwamahlumela amatsha ngexesha lokukhula kwezityalo.Ngexesha lokukhula kwezityalo, ukufaka iurea kunokukhuthaza ukukhula kwamahlumela amatsha kwizityalo, ngakumbi imithi yeziqhamo.Ukusetyenziswa kwe-urea kwizityalo kunokukhuthaza isiqulatho senitrogen kumagqabi esityalo, kukhawulezise ukukhula kwamahlumela amatsha, kwaye kuthintele amathupha entyatyambo.
(3) IUrea, njengesichumiso samagqabi, inokongeza izityalo ngesichumiso ngelixa ibulala izitshabalalisi.Ukunyibilikisa iurea kunye nesicoci sokuhlamba impahla emanzini acocekileyo kunye nokuwatshiza emagqabini ezityalo kunokuphinda kuzalise izichumisi kwaye kubulale ngokufanelekileyo ezinye izinambuzane.Ukubulala izitshabalalisi ezithambileyo ezifana nooqongqothwane bekhaphetshu, iintwala kunye nezigcawu ezibomvu zifikelela ngaphezulu kwama-90%.Njengesichumisi esingathathi hlangothi, i-urea ifunxwa lula ngamagqabi kwaye inomonakalo omncinci kakhulu kwizityalo.
