Urea

ibisobanuro bigufi:

Ni ifumbire mvaruganda igizwe na karubone, azote, ogisijeni na hydrogène, kimwe mu bintu byoroshe kama kama, kandi nicyo kintu nyamukuru kirimo azote ya nyuma ya protein metabolism no kubora mu nyamaswa z’inyamabere n’amafi amwe, kandi urea ikomatanyirizwa na amoniya na dioxyde de carbone mu nganda mu bihe bimwe na bimwe.

Composition Ibigize, imiterere nibitunga umubiri ni bimwe, uburyo bwo kurekura intungamubiri nuburyo bwo kwinjiza ni kimwe, kandi ibirimo amazi, ubukana, ibirimo ivumbi hamwe nubwikorezi hamwe nububiko bwibintu bitandukanye.

Rate Igipimo cyo gusesa, igipimo cyo kurekura intungamubiri n’ifumbire mvaruganda iratandukanye, kandi igipimo cyo gusesagura uduce duto twihuta kandi ingaruka zirihuta; Iseswa ryibice binini biratinda kandi igihe cyo gusama ni kirekire.

③ Ibiri muri urea biuret nini biri munsi yutuntu duto duto, dukoreshwa nkifumbire fatizo, cyangwa ibice binini bikoreshwa mugukora ifumbire mvanze. Kuri topdressing, urea ntoya ya granula ikoreshwa mugutera gutera amababi, gushira umwobo, gushiramo umwobo no gufumbira ifumbire, hamwe no gukoresha amazi.

Ure Urea-nini ya urea ifite umukungugu muke ugereranije na ureya ntoya, imbaraga zo gukomeretsa cyane, amazi meza, irashobora gutwarwa kubwinshi, ntibyoroshye kumeneka no guteka, kandi bikwiriye gusama imashini.

Kugenzura ifumbire

[Guhindura ingano yindabyo] Kugirango utsinde umwaka munini kandi muto wumurima wa pome, utera 0.5% yumuti wamazi wa urea hejuru yamababi mugihe cyibyumweru 5-6 nyuma yo kurabyo (igihe gikomeye cyo gutandukanya ururabyo rwa pome rwa pome, imikurire yimishitsi mishya iratinda cyangwa igahagarara, kandi nitorojeni yibibabi byerekana amababi yerekana), gutera inshuro ebyiri zikurikiranye, bishobora kwihutisha gukura kwururabyo rwinshi, bikabuza gukura kwinshi kwururabyo, kwihuta kwinshi kwururabyo, kwihuta kwinshi kwururabyo.

[Indabyo n'imbuto kunanuka] Ibice byururabyo rwamashaza byumva cyane urea, ariko kubyitwaramo biratinda, nuko amashaza yamahanga hamwe nigeragezwa rya urea, ibisubizo byerekana ko amashaza nindabyo za nectarine nimbuto zera, bikenera kwibanda cyane (7.4%) kugirango bigaragaze ibisubizo byiza, kwibanda cyane ni 8% -12%, ibyumweru 1-2 nyuma yo gutera, kugirango ugere ku ntego yo kumera indabyo n'imbuto.

Umusaruro w'imbuto z'umuceri] Mu buhanga bwo gutanga imbuto z'umuceri wa Hybrid, mu rwego rwo kuzamura igipimo cy’ababyeyi, mu rwego rwo kongera umusaruro w’imbuto z'umuceri wa Hybrid cyangwa umubare w’uburumbuke bw’imirongo ya sterile, ubushakashatsi bwakorewe hamwe na urea aho kuba gibberellin, no gukoresha urea 1.5% kugeza kuri 2% mu cyiciro cyo gutwita kandi icyiciro cya mbere cy’amatwi (20% cyo gutoranya ugutwi), ingaruka z’uburumbuke ntizigeze ziyongera kuri gibberellin.

[Kurwanya udukoko] Hamwe na urea, ifu yo gukaraba, amazi 4: 1: 400, nyuma yo kuvanga, irashobora gukumira ibiti byimbuto, imboga, aphide yipamba, ibitagangurirwa bitukura, udukoko twitwa cabage nudukoko twangiza, ingaruka zica udukoko zirenga 90%. Ifumbire ya Urea fer] Urea ikora fer ya chelated hamwe na Fe2 + muburyo bugoye. Ubu bwoko bw'ifumbire mvaruganda ifite igiciro gito kandi bigira ingaruka nziza mukurinda kubura fer no gutakaza icyatsi. Ingaruka zo kurwanya chlorose iruta iya 0.3% ferrous sulfate.

Gucapa imyenda no gusiga irangi

① Irashobora gukoreshwa nkumubare munini wa melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, cafeyine, VAT brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate nibindi bicuruzwa bitanga ibikoresho bibisi.

② Ifite ingaruka nziza kumashanyarazi yimiti yicyuma nicyuma, kandi ikoreshwa nkigikoresho cyo kwangirika kwangiza ibyuma, kandi ikoreshwa no mugutegura amazi ya palladium.

③ Mu nganda, ikoreshwa kandi nkibikoresho fatizo byo gukora urea-formaldehyde, polyurethanes na melamine-formaldehyde.

AgentIbikoresho byatoranijwe bigabanya kugabanya imyuka yaka umuriro, hamwe na urea yimodoka, igizwe na 32.5% urea-isukuye cyane hamwe n’amazi 67.5%.

⑤ Gutandukanya ibishashara bya paraffin (kubera ko urea ishobora gukora clathrates), ibikoresho bivunika, ibice bya lisansi yo kurengera ibidukikije, ibice by amenyo yera, ifumbire mvaruganda, ibikoresho byingenzi bifasha gusiga no gucapa.

Industry Inganda zikora imyenda ninziza nziza yo gusiga / hygroscopic agent / viscose fibre yagura agent, resin irangiza, ifite uburyo bwinshi bwo gukoresha. Kugereranya imiterere ya hygroscopique ya urea hamwe nibindi bikoresho bya hygroscopique mu nganda z’imyenda: igereranya nuburemere bwayo.

Urwego rwo kwisiga (ibikoresho byoherejwe)

Dermatology ikoresha ibintu bimwe na bimwe birimo urea kugirango yongere ububobere bwuruhu. Kwambara bifunze bikoreshwa mumisumari idakuwe kubagwa birimo urea 40%. Urea ni ikintu cyiza gitanga amazi, kibaho muri cicicle yuruhu, nikintu gisanzwe cyuruhu rwa NMF igice cyingenzi.
