① Kuumbwa, hunhu uye huturu hwemukati hwakafanana, kuburitswa kwekudya uye kunwisa kwakafanana, uye zvemukati zvemvura, kuoma, guruva zvemukati uye kutakura uye kuchengetedza kuramba kwezvikamu zvakasiyana.
② The disolution rate, nutrient release rate uye fertilizer rate yezvikamu zvakasiyana, uye kuparara kwezvimedu zviduku kunokurumidza uye mhedzisiro inokurumidza;Kuparara kwezvimedu zvakakura kunononoka uye nguva yekuberekesa yakareba.
③ Zvinyorwa zveurea biuret zvakakura zvakaderera pane zvidiki zviduku, izvo zvinoshandiswa sefotereza yepasi, kana zvidimbu zvakakura zvinoshandiswa pakugadzirwa kwemafetereza akasanganiswa.Kuisa pamusoro, diki granular urea inoshandiswa kupfapfaidza foliar, kuisa gomba, kuisa mugero uye kuisa fetereza yekubvisa, uye kuisa mvura nemvura.
④ Huru-chimedu urea ine yakaderera guruva yemukati kana ichienzaniswa nediki-particle urea, yakakwirira compression simba, yakanaka fluidity, inogona kutakurwa yakawanda, haisi nyore kupaza nekukaka, uye inokodzera kugadzirwa nemichina.
EVERBRIGHT® 'ichapawo zvakagadziridzwa:zvirimo/kuchena/particlesize/PHvalue/ruvara/packagingstyle/ kurongedzerwa kutaurwa uye zvimwe zvinhu zvakanyanyonangana nemamiriro ako ekushandisa, uye zvinopa mahara samples.

Fertilization control
[Kugadziriswa kwehuwandu hwemaruva]Kuti ukunde gore guru uye diki remunda weapuro, kumwaya 0.5% urea aqueous solution pashizha pamavhiki mashanu kusvika matanhatu mushure mekutumbuka (nguva yakaoma yekusiyanisa maruva eapuro, kukura kwenhungirwa kunonoka kana kumira. , uye nitrogen yemukati yemashizha inoratidza kuderera kwemaitiro), kupfapfaidza kaviri mumutsara, kunogona kuwedzera nitrogen yemashizha emashizha, kukurumidza kukura kwemashizha matsva, kudzivisa kusiyanisa kwemaruva, uye kuita kuti maruva akawanda egore guru zvakakodzera.
[Ruva nemichero kuonda]Peach ruva nhengo dzinonyanya kunzwira urea, asi kuita kunononoka, saka vatorwa pichisi pamwe urea bvunzo, zvabuda zvinoratidza kuti pichisi uye nectarine ruva uye michero kuonda, vanoda guru concentration (7.4%) kuratidza migumisiro yakanaka, zvikuru akakodzera. kusungirirwa ndeye 8% -12%, mavhiki 1-2 mushure mekupfapfaidza, kuzadzisa chinangwa chemaruva uye michero kuonda.
[Kugadzirwa kwembeu yemupunga]Mune tekinoroji yekugadzirwa kwembeu yemupunga yakasanganiswa, kuitira kuvandudza mwero wevabereki, kuitira kuwedzera huwandu hwekugadzirwa kwembeu yemupunga wakasanganiswa kana huwandu hwekubereka hwemitsara isina mbereko, kuedza kwakaitwa neurea pachinzvimbo chegibberellin, uye kushandiswa. ye 1.5% kusvika 2% urea padanho repamusoro repamuviri uye danho rekutanga nzeve (20% sarudzo yenzeve), chibereko chekubereka chakafanana negibberellin, uye haina kuwedzera urefu hwechirimwa.
[Kudzora zvipembenene]Ne urea, washing powder, mvura 4: 1: 400, mushure mekusanganiswa, inogona kudzivirira miti yemichero, miriwo, donje aphid, spider tsvuku, tupukanana kabichi uye zvimwe zvipembenene, insecticidal effect inopfuura 90%.[Urea iron fertilizer] Urea inoumba chelated iron ine Fe2+ muchimiro chekuoma.Iyi mhando ye organic iron fetireza ine mutengo wakaderera uye yakanaka mhedzisiro pakudzivirira kushomeka kwesimbi uye kurasikirwa kwegirinhi.Kudzora mhedzisiro yechlorosis iri nani pane iyo ye0.3% ferrous sulfate.
Textile kudhinda uye dhayi
① Inogona kushandiswa senhamba yakakura ye melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, VAT brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate uye zvimwe zvigadzirwa kugadzira mbishi zvinhu.
② Iine kupenya kunokonzera kupenya kwemakemikari esimbi uye simbi isina tsvina, uye inoshandiswa se corrosion inhibitor musimbi pickling, uye inoshandiswawo mukugadzirira palladium activation liquid.
③ Muindasitiri, inoshandiswawo sechinhu chakabikwa chekugadzira urea-formaldehyde resins, polyurethanes uye melamine-formaldehyde resins.
④Iyo inosarudza inodzikisira mumiriri wekubvisa gasi rinopisa rinopisa, pamwe nemotokari urea, iyo inoumbwa ne32.5% yakakwirira-kuchena urea uye 67.5% deionized mvura.
⑤ Kupatsanura parafini wakisi (nekuti urea inogona kugadzira clathrates), zvinhu zvinoramba, zvikamu zveinjini yekudzivirira nharaunda, zvinhu zvinochenesa mazino zvigadzirwa, makemikari fetiraiza, akakosha anobatsira ekudhaya nekudhinda.
⑥ indasitiri yemachira yakanakisa dhayi solvent/hygroscopic agent/viscose faibha yekuwedzera mumiririri, resin inopedzisa mumiririri, ine akawanda mashandisiro.Kuenzanisa kweiyo hygroscopic zvimiro zveurea nemamwe ma hygroscopic agents muindasitiri yemachira: chiyero kune huremu hwayo.
Cosmetic giredhi (inonyorovesa chinhu)
Dermatology inoshandisa mamwe maajenti ane urea kuwedzera mwando weganda.Iyo yakavharwa yekupfeka inoshandiswa kune isina kuvhiyiwa mbambo ine 40% urea.Urea chinhu chakanaka chekunyorovesa chinhu, chiripo muganda reganda, ndiyo ganda rinogadzika moisturizing factor NMF main component.
