Wolemba Urea

Kufotokozera Kwachidule:

Urea ndizopanda zonunkhira, zopangidwa ndi granular, Chida ichi chadutsa chizindikiritso cha ISO9001 ndipo chidapatsidwa zinthu zoyambirira zaku China zomwe siziyang'aniridwa ndi boma laukadaulo ndiukadaulo, Izi zili ndi zinthu ngati polypeptide urea, granular urea komanso zotayidwa urea.

Urea ndizopanda zonunkhira, zopangidwa ndi granular;

Mankhwala wadutsa ndi ISO9001 khalidwe dongosolo chitsimikizo ndipo anali kupereka mankhwala woyamba Chinese kuchotsedwa kuyang'aniridwa ndi boma Bureau a khalidwe ndi kuyang'aniridwa luso;

Izi zili ndi zinthu zofananira monga polypeptide urea, granular urea ndi prilled urea.

Urea (Carbamide / Urea solution / USP kalasi Carbamide) ndiyosungunuka mosavuta m'madzi ndipo imagwiritsidwa ntchito ngati feteleza wambiri wosatulutsa msanga wa nayitrogeni. Kusakanikirana kosavuta m'malere ndi m'misewu. Wotchuka omwe amagwiritsidwa ntchito mu feteleza wa NPK & feteleza wa BB ngati chinthu choyambirira, amathanso kupaka sulfa kapena polima ngati feteleza wotulutsidwa pang'onopang'ono kapena wotulutsidwa. Kugwiritsa ntchito urea kwa nthawi yayitali sikungakhalebe zinthu zoyipa m'nthaka.

Urea imakhala ndi biuret yaying'ono pamagetsi, pomwe biuret imaposa 1%, urea singagwiritsidwe ntchito ngati mbeu ndi fetereza wam'mimba. Chifukwa cha kuchuluka kwa nayitrogeni ku urea, ndikofunikira kukwaniritsa kufalikira. Kubowola sikuyenera kuchitika mukakhudzana kapena kufesa mbewu, chifukwa chowopsa chakumera. Urea imasungunuka m'madzi kuti igwiritsidwe ntchito ngati kupopera kapena kudzera mu njira zothirira.

Urea ndi yolimba yoyera yolimba. Ndi molekyulu ya amide yokhala ndi 46% ya nayitrogeni mwa mawonekedwe amine magulu. Urea imasungunuka kwambiri m'madzi ndipo ndi yoyenera kugwiritsidwa ntchito ngati feteleza waulimi ndi nkhalango komanso mafakitale omwe amafunikira nitrojeni wapamwamba kwambiri. Sili poizoni wa zinyama ndi mbalame ndipo ndi mankhwala abwino komanso otetezeka kuti agwire. 

Zoposa 90% zamafuta apadziko lonse a urea amayenera kugwiritsidwa ntchito ngati feteleza wotulutsa nayitrogeni. Urea imakhala ndi nayitrogeni wapamwamba kwambiri kuposa feteleza onse olimba omwe amagwiritsa ntchito. Chifukwa chake, ili ndi mtengo wotsika kwambiri wonyamula pamtundu uliwonse wa michere ya nayitrogeni.
Mabakiteriya ambiri amtundu wa nthaka amakhala ndi urease wa enzyme, womwe umathandizira kusintha kwa urea kukhala ammonia kapena ammonium ion ndi bicarbonate ion, motero feteleza wa urea amasinthidwa mwachangu kwambiri kukhala mtundu wa ammonium mu dothi. Pakati pa mabakiteriya a nthaka omwe amadziwika kuti amanyamula urease, mabakiteriya ena a ammonia-oxidizing (AOB), monga mitundu ya Nitrosomonas, amathanso kuyambitsa kaboni dayokisaidi yomwe imatulutsidwa ndi zomwe zimapanga biomass kudzera pa Calvin Cycle, ndikututa mphamvu poonjezera ammonia kuti nitrite, njira yotchedwa nitrification. Nitrite-oxidizing mabakiteriya, makamaka Nitrobacter, oxidize nitrite ku nitrate, yomwe imayenda kwambiri m'nthaka chifukwa chazoyipa zake ndipo imayambitsa kuipitsa madzi kuchokera kuulimi. Ammonium ndi nitrate amalowetsedwa mosavuta ndi zomera, ndipo ndiwo magwero akuluakulu a nayitrogeni pakukula kwazomera. Urea imagwiritsidwanso ntchito popanga feteleza ambiri olimba kwambiri. Urea imasungunuka kwambiri m'madzi ndipo, motero, ndiyofunikanso kwambiri kugwiritsidwa ntchito pamafuta a feteleza mwachitsanzo, mu feteleza wa 'foliar'. Pogwiritsa ntchito feteleza, timadzi timene timakonda kwambiri kuposa ma prill chifukwa chakuchepa kwa kukula kwa tinthu tating'onoting'ono, komwe ndi mwayi wogwiritsa ntchito makina.
Urea nthawi zambiri imafalikira pamitengo ya pakati pa 40 ndi 300 kg / ha koma mitengo imasiyanasiyana. Ntchito zing'onozing'ono zimabweretsa zotayika zochepa chifukwa cha leaching. M'nyengo yotentha, urea imafalikira nthawi yayitali kapena nthawi yamvula kuti muchepetse kutayika kwa volatilization (momwe nitrogeni imasokera mumlengalenga ngati mpweya wa ammonia). Urea siyigwirizana ndi feteleza wina.
Chifukwa cha kuchuluka kwa nayitrogeni ku urea, ndikofunikira kwambiri kuti ifalikire. Zipangizo zogwiritsira ntchito ziyenera kusungidwa moyenera ndikugwiritsa ntchito moyenera. Kubowola sikuyenera kuchitika mukakhudzana kapena kufesa mbewu, chifukwa chowopsa chakumera. Urea imasungunuka m'madzi kuti igwiritsidwe ntchito ngati kupopera kapena kudzera mu njira zothirira.

Mu mbewu zambewu ndi thonje, urea imagwiritsidwa ntchito nthawi yolima yomaliza musanadzalemo. M'madera omwe kumagwa mvula yambiri komanso dothi lamchenga (pomwe nayitrogeni imatha kutayika kudzera mu leaching) komanso komwe kumayembekezereka mvula yabwino mu nyengo, urea imatha kukhala mbali- kapena kuvala bwino nthawi yokula. Zovala zapamwamba ndizotchuka podyetsa msipu. Pakulima nzimbe, urea amavekedwa pambali mutabzala, ndipo amagwiritsidwa ntchito pachilichonse cha ratoon.
Mu mbewu zothiriridwa, urea itha kugwiritsidwa ntchito youma panthaka, kapena kusungunuka ndikugwiritsidwa ntchito kudzera m'madzi othirira. Urea idzasungunuka ndi kulemera kwake m'madzi, koma zimakhala zovuta kwambiri kuti zisungunuke ndikungowonjezera. Kutha urea m'madzi ndikutha, kuchititsa kutentha kwa yankho kugwa urea ikasungunuka.
Monga chitsogozo chothandiza, pokonzekera njira zothetsera urea (jekeseni m'mizere yothirira), sungunulani osapitilira 3 g urea pa 1 L madzi.
M'mapiritsi a foliar, kuchuluka kwa urea kwa 0,5% - 2.0% amagwiritsidwa ntchito nthawi zambiri m'minda yolima. Magulu otsika a urea nthawi zambiri amawonetsedwa.
Urea imayamwa chinyezi kuchokera mumlengalenga motero imasungidwa m'matumba otsekedwa / osindikizidwa pallets kapena, ngati amasungidwa mochuluka, pansi pa chivundikiro ndi lona. Monga momwe zilili ndi feteleza olimba kwambiri, ndikofunika kuti muzisungira malo ozizira, owuma, komanso mpweya wokwanira.
Kuchulukitsa kapena kuyika Urea pafupi ndi mbewu ndizovulaza.

Makampani opanga mankhwala.
Urea ndizopangira zopangira zida zazikulu ziwiri: urea-formaldehyde resins ndi urea-melamine-formaldehyde yomwe imagwiritsidwa ntchito plywood yam'madzi.
