Magadzirirwo:

Mamiriro: 

Urea inogadzirwa isina hwema, granular zvigadzirwa;

Ichi chigadzirwa chapfuura iyo ISO9001 yemhando system chitupa uye yakapihwa yekutanga zvigadzirwa zveChinese zvinoregererwa kuongororwa nehurumende Bureau yemhando yepamusoro uye technical technical;

Ichi chigadzirwa chine zvigadzirwa zvine hukama senge polypeptide urea, granular urea uye prilled urea.

Urea (Carbamide / Urea solution / USP Giredhi Carbamide) iri nyore kusungunuka mumvura uye inoshandiswa seyakarerekera nekukurumidza-yakaburitswa yakakwira huwandu hweiyo nitrogen fetiraiza. Nyore hygroscopic mumhepo nekutora. Yakakurumbira inoshandiswa muNPK kompiresa fotereza & BB mafetira seyakakosha mbishi zvinhu, zvakare inogona kuvezwa sarufa kana polymer seinononoka-kuburitswa kana kudzora-yakaburitswa fetiraiza. Kugara-kwenguva kushandiswa kweurea hakurambe kuri chero chinhu chinokuvadza kune ivhu.

Urea ine diki reiyo biuret mune granulation maitiro, kana biuret zvemukati zvichidarika 1%, urea haigone kushandiswa sekudyara uye foliar fetiraiza Nekuda kweiyo yakakwira nitrogen yekumanikidza muurea, zvakakosha kuti uwane kunyange kutopararira. Kuchera hakufanirwe kuitika pakubata kana padyo nembeu, nekuda kwenjodzi yekukuvara kwekumera. Urea inonyungudika mumvura kuti ishandiswe se spray kana kuburikidza nehurongwa hwekudiridza.

Urea idenderedzwa chena yakasimba. Iyo organic organic amide Morekuru rine 46% senitrogen muchimiro chemapoka eamini. Urea inonyungudika isingagumi mumvura uye inokodzera kushandiswa sefetiraiza yezvekurima uye yemasango pamwe neyekushandisa mumaindasitiri iyo inoda mhando yeinitrogen yepamusoro. Haisi chepfu kuzvipfuwo neshiri uye ikemikari inotyisa uye yakachengeteka kubata. 

Zvinopfuura makumi mapfumbamwe kubva muzana epasi rese kugadzirwa kwemaindasitiri eurea yakagadzirirwa kushandisa senitrogen-kuburitsa fetiraiza. Urea ine yepamusoro senitrogen yezvinhu zvese zvine nitrogenous manyowa anoshandiswa zvakajairika. Naizvozvo, ine yakaderera mari yekufambisa pamubato we nitrogen zvinovaka muviri.
Mazhinji mabhakitiriya epasi ane iyo enzyme urease, iyo inokonzeresa kushandurwa kweiyo urea kuva ammonia kana ammonium ion uye bicarbonate ion, nekudaro maferesa eurea anoshandurwa nekukurumidza zvikuru kuita fomu yeammonium muvhu. Pakati pebhakitiriya repasi rinozivikanwa kutakura urease, mamwe amoniya-oxidizing mabhakitiriya (AOB), senge mhando dzeNitrosomonas, anokwanisa zvakare kugadzira carbon dioxide yakaburitswa nemhinduro yekuita biomass kuburikidza neCalvin Cycle, uye kukohwa simba nekusanganisa ammonia ku nitrite, maitiro anonzi nitrification. Nitrite-oxidizing bacteria, kunyanya Nitrobacter, oxidize nitrite kune nitrate, inova inofamba kwazvo muvhu nekuda kwekuipa kwayo kwakashata uye ndiyo honzeri huru yekusvibiswa kwemvura kubva mune zvekurima. Ammonium uye nitrate zvinonyorerwa zvirimwa zviri nyore, uye ndiwo manyuko makuru enitrogen yekukura kwezvirimwa. Urea inoshandiswawo mune akawanda akawanda-echinhu akasimba manyowa mafomu. Urea inonyungudika kwazvo mumvura uye, nekudaro, zvakare inokodzera kushandiswa mumushonga wefetiraiza, mu 'foliar feed' mafetiraiza. Zvekushandisa fetiraiza, granules dzinosarudzwa pamusoro pemaprills nekuda kwekupararira kwavo kwehukuru hwemashupu, inova mukana wekushandisa muchina.
Urea inowanzopararira pamitengo iri pakati pe40 ne300 kg / ha asi mitengo inosiyana. Zvishandiso zvidiki zvinounza kurasikirwa kwakaderera nekuda kwekudonha. Munguva yezhizha, urea inowanzo pararira nguva isati yatanga kana panguva yemvura yekudzora kurasikirwa kubva ku volatilization (maitiro umo nitrogen inorasika kumhepo se ammonia gasi). Urea haienderane nemamwe mafetiraiza.
Nekuda kweiyo yakakwira nitrogen yevasungwa mune urea, zvakakosha kuti uwane kunyange kupararira. Iyo yekushandisa michina inofanirwa kuve yakanyatsogadziriswa uye kunyatsoshandiswa. Kuchera hakufanirwe kuitika pakubata kana padyo nembeu, nekuda kwenjodzi yekukuvara kwekumera. Urea inonyungudika mumvura kuti ishandiswe se spray kana kuburikidza nehurongwa hwekudiridza.

Muchirimwa chezviyo nedonje, urea inowanzo shandiswa panguva yekurima kwekupedzisira usati wadyara. Munzvimbo dzinonaya mvura yakawanda uye paivhu rine jecha (panogona kurasikirwa nitrogen kuburikidza neaching) uye panotarisirwa mvura yakanaka yemumwaka, urea inogona kuve padivi- kana kupfeka pamusoro munguva yekukura. Kupfeka-kwepamusoro kunozivikanwawo pamafuro nezvirimwa zvekudya. Mukurima nzimbe, urea inopfekedzwa-parutivi mushure mekudyara, uye inoiswa kune yega ratoon chirimwa.
Muzvirimwa zvinodiridzwa, urea inogona kuiswa yakaoma kune ivhu, kana kunyungudika yoiswa kuburikidza nemvura yekudiridzira. Urea inonyungudika nehuremu hwayo mukati memvura, asi zvinowedzera kuoma kunyungudika sezvo kuwanda kuchikura. Kuparadzanisa urea mumvura kunopera, zvichikonzera tembiricha yemhinduro kudonha kana urea yaparara.
Seye inoshanda nhungamiro, paunenge uchigadzirira urea mhinduro dzekubereka (jekiseni mumitsara yekudiridza), nyungudutsa kwete anopfuura matatu g urea pa1 L mvura.
Mune foliar sprays, urea kuwanda kwe0.5% - 2.0% inowanzo shandiswa mune horticultural zvirimwa. Yakaderera-biuret mamaki eurea anowanzo kuratidzwa.
Urea inotora hunyoro kubva mudenga uye nekudaro inowanzo chengetwa kungave akavharwa / akavharika mabhegi pamapalleti kana, kana akachengetwa muhuwandu, pasi pekuvharidzirwa netaraini. Sezvakaita mafetiraiza akasimba, kunochengeterwa munzvimbo inotonhorera, yakaoma, ine mweya wakakwana.
Kuwedzeredza kana kuisa Urea padyo nembeu kunokuvadza.

Chemical indasitiri.
Urea inogadzirwa nemhando mbiri dzekugadzira: urea-formaldehyde resini uye urea-melamine-formaldehyde inoshandiswa mune plywood yemumvura.
