I-Urea ngumkhiqizo ongenaphunga, oyimbudumbudu;

Lo mkhiqizo udlule isitifiketi sohlelo lwekhwalithi le-ISO9001 futhi wanikezwa imikhiqizo yokuqala yamaShayina ekhululiwe ekuhlolweni yihhovisi likahulumeni lekhwalithi kanye nokuqondiswa kobuchwepheshe;

Lo mkhiqizo unemikhiqizo ehlobene ne-polypeptide urea, i-granular urea ne-urea ehlohliwe.

I-Urea (isixazululo seCarbamide / i-Urea / i-USP Grade Carbamide) incibilika kalula emanzini futhi isetshenziswa njengendawo yokufaka umanyolo we-nitrogen ongathathi hlangothi ongathathi hlangothi. I-hygroscopic elula emoyeni nase-caking. Okudume kakhulu okusetshenziswe kumanyolo wezakhi ze-NPK kanye nomanyolo we-BB njengezinto eziyisisekelo eziluhlaza, nakho kungafaka isulfure noma i-polymer njengomanyolo okhishwa kancane noma olawulwa ngokulawulwa. Ukusetshenziswa kwesikhathi eside kwe-urea akuhlali kukhona izinto eziyingozi emhlabathini.

I-Urea iqukethe inani elincane le-biuret enqubeni ye-granulation, lapho okuqukethwe kwe-biuret kudlula i-1%, i-urea ayinakusetshenziswa njenge-seeding kanye ne-foliar fertilizer.Ngenxa yokuhlushwa okuphezulu kwe-nitrogen e-urea, kubaluleke kakhulu ukufeza ukusabalala ngisho. Ukubhola akumele kwenzeke lapho kuthintwa noma kusondele imbewu, ngenxa yengozi yokulimala kokuhluma. I-Urea ichitheka emanzini ukuze isetshenziswe njengesifutho noma ngezinhlelo zokunisela.

I-Urea isiqinile esiyindilinga esimhlophe. Kuyinto i-organic amide molecule equkethe i-nitrogen engu-46% ngendlela yamaqembu e-amine. I-Urea incibilika ngokungenamkhawulo emanzini futhi ilungele ukusetshenziswa njengomanyolo wezolimo nowamahlathi kanye nezicelo zezimboni ezidinga umthombo we-nitrogen osezingeni eliphakeme. Akuwona ubuthi ezilwaneni ezincelisayo nezinyoni futhi uyikhemikhali enobungozi futhi ephephile ongayiphatha. 

Ngaphezu kwama-90% womkhiqizo wezimboni zomhlaba we-urea wenzelwe ukusetshenziswa njengomanyolo okhishwa nge-nitrogen. I-Urea inokuqukethwe okuphezulu kwe-nitrogen kwawo wonke umanyolo oqinile we-nitrogenous osetshenziswa ngokujwayelekile. Ngakho-ke, inezindleko zokuhamba eziphansi kakhulu ngeyunithi ngayinye yezakhi zenitrogen.
Amagciwane amaningi omhlabathi ane-enzyme urease, eyenza ukuthi ukuguqulwa kwe-urea kube ukuguqulwa kube yi-ammonia noma i-ammonium ion ne-bicarbonate ion, ngakho-ke umanyolo we-urea uguqulwa ngokushesha okukhulu ube yifomu le-ammonium enhlabathini. Phakathi kwamagciwane enhlabathi aziwa ngokuthwala i-urease, amanye ama-bacterium e-ammonia-oxidizing (AOB), afana nezinhlobo ze-Nitrosomonas, nawo ayakwazi ukufaka i-carbon dioxide ekhishwe yi-reaction yokwenza i-biomass ngeCalvin Cycle, nokuvuna amandla ngokufaka i-oxidizing ammonia ku i-nitrite, inqubo ebizwa ngokuthi i-nitrification. Ama-bacterium e-nitrite-oxidizing, ikakhulukazi i-Nitrobacter, enza i-oxidize nitrite ibe yi-nitrate, ehamba kakhulu emhlabathini ngenxa yokushaja kwayo okungekuhle futhi iyimbangela enkulu yokungcola kwamanzi okuvela kwezolimo. I-ammonium ne-nitrate zimuncwa kalula yizitshalo, futhi ziyimithombo ephezulu ye-nitrogen yokukhula kwezitshalo. I-Urea iyasetshenziswa futhi ekwakhiweni okuningi komanyolo okuqinile okwenziwa ngezinto eziningi. I-Urea incibilika kakhulu emanzini futhi, ngakho-ke, ibuye ilungele ukusetshenziswa kwizixazululo zikamanyolo isib, kumanyolo we-'foliar feed ' Ukusetshenziswa komanyolo, ama-granules ancanyelwa ngaphezu kwama-prill ngenxa yokusatshalaliswa kwawo ngosayizi wezinhlayiyana ezincane, okuyinzuzo yokusetshenziswa kwemishini.
I-Urea ivame ukusakazwa ngamanani aphakathi kuka-40 no-300 kg / ha kepha amazinga ayahluka. Izinhlelo zokusebenza ezincane zithola ukulahlekelwa okuphansi ngenxa yokuvuza. Ehlobo, i-urea ivame ukusakazwa ngaphambi nje noma ngesikhathi semvula ukunciphisa ukulahleka kusuka ku-volatilization (inqubo lapho i-nitrogen ilahleka emkhathini njengegesi ye-ammonia). I-Urea ayihambelani neminye imanyolo.
Ngenxa yokuhlushwa okuphezulu kwe-nitrogen e-urea, kubaluleke kakhulu ukufeza ukusakazeka okulinganayo. Imishini yokufaka isicelo kufanele ilinganiswe kahle futhi isetshenziswe kahle. Ukubhola akumele kwenzeke lapho kuthintwa noma kusondele imbewu, ngenxa yengozi yokulimala kokuhluma. I-Urea ichitheka emanzini ukuze isetshenziswe njengesifutho noma ngezinhlelo zokunisela.

Ezitshalweni zokusanhlamvu nezokotini, i-urea ivame ukusetshenziswa ngesikhathi sokulima kokugcina ngaphambi kokutshala. Ezindaweni ezinemvula ephezulu nasemhlabathini onesihlabathi (lapho i-nitrogen ingalahleka ngokusebenzisa i-leaching) nalapho kulindeleke khona imvula enhle yangesizini, i-urea ingaba eceleni noma igqoke kahle ngesikhathi sokukhula. Ukugqoka okuphezulu futhi kuyathandwa emadlelweni nasezitshalweni zokudla. Ekulimeni umoba, i-urea igqokiswe ohlangothini ngemuva kokutshala, futhi isetshenziswa kwisilimo ngasinye sikaratoon.
Ezitshalweni eziniselwa ngenkasa, i-urea ingasetshenziswa yomile enhlabathini, noma ichithwe isetshenziswe ngamanzi okunisela. I-Urea izoncibilika ngesisindo sayo emanzini, kepha kuya kuba nzima ukuncibilika njengoba ukugxila kukhuphuka. Ukuqeda i-urea emanzini kuphelile, kubangele ukushisa kwesixazululo ukuwa lapho urea uncibilika.
Njengomhlahlandlela osebenzayo, lapho ulungiselela izixazululo ze-urea zokufaka umanyolo (ukujova emigqeni yokunisela), ungancibiliki ngaphezu kwama-3 g we-u ngamanzi angu-1 L
Kuma-foliar sprays, ukugxila kwe-urea okungu-0.5% - 2.0% kuvame ukusetshenziselwa izitshalo ze-horticultural. Amabanga aphansi e-uuret we-urea akhonjiswa kaningi.
I-Urea imunca umswakama osemkhathini ngakho-ke ngokuvamile igcinwa ezikhwameni ezivaliwe / ezivaliwe kuma-pallets noma, uma zigcinwe ngobuningi, ngaphansi kwesembozo ngoseyili. Njengakwamanyolo omningi oqinile, kunconywa ukugcina endaweni epholile, eyomile, enomoya omuhle.
Ukweqisa ngokweqile noma ukubeka i-Urea eduze nembewu kuyingozi.

Imboni yamakhemikhali.
I-Urea yinto eluhlaza yokwenziwa kwezigaba ezimbili eziyinhloko zezinto zokwakha: i-urea-formaldehyde resins kanye ne-urea-melamine-formaldehyde esetshenziswa kupulangwe lwasolwandle.
