I-Urea yinto engenasiphelo, iimveliso zegranular;
Le mveliso idlulisile ukuqinisekiswa kwenkqubo esemgangathweni ye-ISO9001 kwaye yanikwa iimveliso zokuqala zaseTshayina ezikhululiwe ekuhlolweni yi-ofisi yombuso esemgangathweni kunye nolawulo lobuchwephesha;
Le mveliso ineemveliso ezinxulumene ne-polypeptide urea, i-granular urea kunye ne-urea e-prilled.
I-Urea (isisombululo seCarbamide / i-Urea / i-USP yeBanga leCarbamide) kulula ukuba inyibilike emanzini kwaye isetyenziswe njenge-nitrogen engakhawulezileyo ekhutshwe ngokukhawuleza. I-hygroscopic elula emoyeni kunye ne-caking. Isetyenziswa kakhulu kwizichumisi ze-NPK kunye nezichumisi ze-BB njengezinto ezisisiseko eziluhlaza, nazo zinokuthambisa isalfure okanye ipolymer njengesichumisi esikhutshwa kancinci okanye esikhutshwa ngolawulo. Ukusetyenziswa kwexesha elide kwe-urea akuhlali naziphi na izinto eziyingozi emhlabeni.
I-Urea iqulethe isixa esincinci se-biuret kwinkqubo ye-granulation, xa umxholo we-biuret ungaphezulu kwe-1%, i-urea ayinakusetyenziswa njengembewu kunye nesichumiso se-foliar. Ngenxa yoxinaniso lwe-nitrogen ephezulu e-urea, kubaluleke kakhulu ukufezekisa nokusasazeka. Ukumba akufuneki kwenzeke xa unxibelelana okanye usondele kwimbewu, ngenxa yomngcipheko womonakalo wokudubula. I-Urea iyanyibilika emanzini ukuze isetyenziswe njengesitshizi okanye ngenkqubo yokunkcenkceshela.
I-Urea yomelele ngokuqinileyo. Yimolekyuli ye-amide ye-organic equkethe i-nitrojeni engama-46% ngohlobo lwamaqela e-amine. I-Urea inyibilika ngokungenasiphelo emanzini kwaye ilungele ukusetyenziswa njengesichumisi sezolimo kunye nesamahlathi kunye nokusetyenziswa kwemizi-mveliso efuna umthombo ophezulu wenitrogen. Ayisiyityhefu kwizilwanyana ezanyisayo nakwiintaka kwaye iyikhemikhali enobungozi kwaye ikhuselekile ukuphatha.
Ngaphezulu kwe-90% yemveliso yehlabathi kwimveliso ye-urea emiselwe ukusetyenziswa njengesichumiso sokukhupha initrogen. I-Urea inomxholo ophezulu we-nitrogen wazo zonke izichumisi eziqinileyo ze-nitrogen ekusebenziseni okuqhelekileyo. Ke ngoko, inexabiso eliphantsi lokuhamba ngeyunithi yenitrogen.
Iibhaktheriya ezininzi zomhlaba zine-urease ye-enzyme, ebangela ukuguqulwa kwe-urea ibe yi-ammonia okanye i-ammonium ion kunye ne-bicarbonate ion, yiyo loo nto izichumisi ze-urea ziguqulwa ngokukhawuleza zenze i-ammonium emhlabeni. Phakathi kweebhaktiriya zomhlaba ezaziwa ngokuba ziphethe i-urease, ezinye iibacteria ze-ammonia-oxidizing (AOB), ezinje ngeentlobo zeNitrosomonas, ziyakwazi ukufaka icarbon dioxide ekhutshwe yimpendulo yokwenza i-biomass ngeCalvin Cycle, kunye nokuvuna amandla ngokwenza oxidizing ammonia i-nitrite, inkqubo ebizwa ngokuba yi-nitrification. Iibacteria zeNitrite-oxidizing, ngakumbi i-Nitrobacter, oxidize nitrite ukuya kwi-nitrate, eshukumayo ngokugqithileyo kwimihlaba ngenxa yetyala elibi kwaye ingoyena nobangela ungcoliseko lwamanzi kwezolimo. I-Ammonium kunye ne-nitrate zifunxwa lula zizityalo, kwaye zezona zinto zingumthombo wenitrogen ekukhuleni kwezityalo. I-Urea ikwasetyenziswa kwizinto ezininzi zezichumiso eziqinileyo. I-Urea inyibilika kakhulu emanzini kwaye ke, ilunge kakhulu ukuba isetyenziswe kwizisombululo zezichumiso umz., Kwizichumisi 'zefoliar'. Ukusetyenziswa kwesichumiso, igranules zikhethwa ngaphezulu kweeprili ngenxa yokusasazeka kwesayizi yamasuntswana, nto leyo eluncedo ekusebenziseni ngomatshini.
I-Urea ihlala isasazeka kumaxabiso aphakathi kwama-40 nama-300 kg / ha kodwa amaxabiso ayahluka. Ukusetyenziswa okuncinci kuzisa ilahleko esezantsi ngenxa yokungena. Ngexesha lasehlotyeni, i-urea ihlala isasazeka ngaphambi nje okanye ngexesha lemvula ukunciphisa ilahleko kwi-volatilization (inkqubo apho i-nitrogen ilahlekile kumoya njengegesi ye-ammonia). I-Urea ayihambelani nezinye izichumisi.
Ngenxa yokuxinana kwenitrogen ephezulu e-urea, kubaluleke kakhulu ukufezekisa nokusasazeka. Izixhobo zesicelo kufuneka zilungiswe ngokuchanekileyo kwaye zisetyenziswe ngokufanelekileyo. Ukumba akufuneki kwenzeke xa unxibelelana okanye usondele kwimbewu, ngenxa yomngcipheko womonakalo wokudubula. I-Urea iyanyibilika emanzini ukuze isetyenziswe njengesitshizi okanye ngenkqubo yokunkcenkceshela.
Kwizityalo eziziinkozo kunye nekotoni, i-urea ihlala isetyenziswa ngexesha lokulima kokugqibela ngaphambi kokutyala. Kwiindawo ezinemvula ephezulu nakwimihlaba enesanti (apho initrogen inokulahleka ngokuvuza) nalapho kulindelwe imvula elungileyo yexesha lonyaka, i-urea inokuba kwicala- okanye inxibe ngaphezulu ngexesha lokukhula. Ukunxiba okuphezulu kuyathandwa emadlelweni nakwizityalo zefula. Ekuhlakuleleni ummoba, i-urea inxibe ecaleni emva kokutyala, kwaye isetyenziswe kwisityalo ngasinye seeratoon.
Kwizityalo zokunkcenkceshela, i-urea ingasetyenziswa yomile emhlabeni, okanye inyibilikiswe kwaye ifakwe emanzini okunkcenkceshela. I-Urea iya kunyibilika kubunzima bayo emanzini, kodwa kuya kusiba nzima ngakumbi ukunyibilika njengoko uxinzelelo lusanda. Ukunyibilika kwe-urea emanzini kuyaphela, kubangela ubushushu besisombululo ukuwa xa urea unyibilika.
Njengesikhokelo esisebenzayo, xa ulungiselela izisombululo ze-urea zokuchumisa (inaliti kwimigca yokunkcenkceshela), unganyibiliki ngaphezulu kwe-3 g ye-urea nge-1 L yamanzi.
Kwizitshizi zefoliar, ugxininiso lwe-urea lwe-0.5% -2.0% zihlala zisetyenziswa kwizityalo ze-horticultural. Amanqanaba e-biuret asezantsi e-urea ahlala eboniswa.
I-Urea ifunxa ukufuma emoyeni kwaye ngenxa yoko igcinwe kwiibhegi ezivaliweyo / ezitywiniweyo kwiipelethi okanye, ukuba zigcinwe ngobuninzi, phantsi kwekhava yetyhubhu. Njengoninzi lwezichumisi, ukugcinwa kwindawo epholileyo, eyomileyo, enomoya owaneleyo kuyacetyiswa.
Ukugqithisa okanye ukubeka i-Urea kufutshane nembewu kuyingozi.
Icandelo lezemichiza.
I-Urea yinto ekrwada ekwenziweni kweeklasi ezimbini eziphambili zezixhobo: i-urea-formaldehyde resins kunye ne-urea-melamine-formaldehyde esetyenziswa kwiplanga laselwandle.
