(Kuchuluka kwa kagwiritsidwe ntchito 'kagwiritsidwe ntchito kazinthu')

① Mapangidwe, mawonekedwe ndi zakudya zomwe zili ndi michere ndizofanana, njira yotulutsira michere ndi mayamwidwe ndizofanana, ndipo madzi, kuuma, fumbi ndi zoyendetsa ndi kusungirako kukana kwa tinthu tating'onoting'ono ndizosiyana.

② Mlingo wa kusungunuka, kuchuluka kwa michere ndi kuchuluka kwa feteleza wa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono timathamanga ndipo zotsatira zake zimathamanga;Kusungunuka kwa tinthu tating'onoting'ono kumachedwa ndipo nthawi ya umuna ndi yayitali.

③ Zomwe zili mu urea biuret zazikulu ndizochepa kusiyana ndi tinthu tating'onoting'ono, zomwe zimagwiritsidwa ntchito ngati feteleza wapansi, kapena tinthu tating'onoting'ono tomwe timagwiritsidwa ntchito popanga feteleza wosakanizidwa.Kupaka pamwamba, urea yaying'ono imagwiritsidwa ntchito kupopera mbewu mankhwalawa, kuthira mabowo, kuthira ngalande ndi kuthira feteleza, ndikuyika ndi madzi.

④ Urea wa tinthu tating'onoting'ono tokhala ndi fumbi lochepa poyerekeza ndi tinthu tating'onoting'ono ta urea, mphamvu yopondereza kwambiri, madzimadzi abwino, amatha kunyamulidwa mochulukira, siwosavuta kuthyoka ndikuyika, ndipo ndi yoyenera kuthira manyowa.

Kugwiritsa Ntchito Mankhwala

Kuwongolera feteleza

[Kusintha kwa kuchuluka kwa maluwa]Pofuna kuthana ndi chaka chachikulu ndi chaching'ono chamunda wa apulo, kupopera mbewu mankhwalawa 0,5% urea madzi amadzimadzi pamasamba pakatha masabata 5-6 maluwa (nthawi yovuta ya kusiyanitsa kwa maluwa a apulo, kukula kwa mphukira zatsopano kumachedwa kapena kuyima). , ndi nayitrogeni zomwe zili m'masamba zimasonyeza kutsika kwake), kupopera mbewu mankhwalawa kawiri motsatizana, kungathe kuonjezera nayitrogeni m'masamba, kufulumizitsa kukula kwa mphukira zatsopano, kulepheretsa kusiyanitsa kwa maluwa, ndi kupanga maluwa a chaka chachikulu kukhala choyenera.

[Maluwa ndi zipatso kupatulira]Pichesi maluwa ziwalo kwambiri tcheru kwa urea, koma anachita pang'onopang'ono, kotero pichesi yachilendo ndi urea mayeso, zotsatira zikusonyeza kuti pichesi ndi nectarine maluwa ndi kupatulira zipatso, ayenera lalikulu ndende (7.4%) kusonyeza zotsatira zabwino, abwino kwambiri. ndende ndi 8% -12%, 1-2 masabata pambuyo kupopera mbewu mankhwalawa, kukwaniritsa cholinga cha maluwa ndi zipatso kupatulira.

[Kulima mbewu za mpunga]Mu teknoloji yopanga mbewu za mpunga wosakanizidwa, kuti apititse patsogolo kuchuluka kwa makolo, kuti awonjezere kuchuluka kwa mbewu za mpunga wosakanizidwa kapena kuchuluka kwa chonde kwa mizere yosabala, kuyesa kunachitika ndi urea m'malo mwa gibberellin, ndikugwiritsa ntchito. wa 1.5% mpaka 2% urea pa mimba pachimake siteji ndi woyamba khutu siteji (20% khutu kusankha), mphamvu chonde anali ofanana gibberellin, ndipo sanali kuonjezera mbewu kutalika.

[Kuletsa tizilombo]Ndi urea, kutsuka ufa, madzi 4:1:400, pambuyo kusanganikirana, zingalepheretse mitengo ya zipatso, masamba, thonje nsabwe za m'masamba, akangaude ofiira, tizilombo kabichi ndi tizirombo tina, insecticidal zotsatira zoposa 90%.[Feteleza wachitsulo wa Urea] Urea amapanga chitsulo cha chelated chokhala ndi Fe2+ m'njira yovuta.Feteleza wachitsulo woterewu amakhala ndi mtengo wotsika komanso amateteza kusowa kwachitsulo komanso kutayika kobiriwira.Kuwongolera kwa chlorosis ndikwabwino kuposa 0,3% ferrous sulfate.

Kusindikiza nsalu ndi utoto

① Itha kugwiritsidwa ntchito ngati utomoni wambiri wa melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, VAT brown BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate ndi zinthu zina zopangira zopangira.

② Imakhala ndi mphamvu yowunikira pakupukuta kwamankhwala achitsulo ndi chitsulo chosapanga dzimbiri, ndipo imagwiritsidwa ntchito ngati inhibitor ya corrosion inhibitor mu pickling zitsulo, komanso imagwiritsidwa ntchito pokonza madzi a palladium activation.

③ M'makampani, amagwiritsidwanso ntchito ngati zopangira popanga urea-formaldehyde resins, polyurethanes ndi melamine-formaldehyde resins.

④Chosankha chochepetsera choletsa kutulutsa mpweya woyaka moto, komanso urea yamagalimoto, yomwe imapangidwa ndi 32.5% yoyera kwambiri ya urea ndi 67.5% yamadzi oyeretsedwa.

⑤ Kulekanitsa sera ya parafini (chifukwa urea imatha kupanga clathrates), zida zokanira, zida zamafuta a injini yoteteza chilengedwe, zida zoyeretsera mano, feteleza wamankhwala, zida zofunikira zothandizira utoto ndi kusindikiza.

⑥ Makampani opanga nsalu ndi njira yabwino kwambiri yosungunulira utoto / hygroscopic agent / viscose fiber kuwonjezera wothandizira, womaliza utomoni, ali ndi ntchito zosiyanasiyana.Kuyerekeza kwa hygroscopic katundu wa urea ndi ma hygroscopic othandizira pamakampani opanga nsalu: chiŵerengero cha kulemera kwake.

Cosmetic kalasi (moisturizing pophika)

Dermatology imagwiritsa ntchito zinthu zina zomwe zimakhala ndi urea kuti ziwonjezere chinyezi pakhungu.Chovala chotsekedwa chomwe chimagwiritsidwa ntchito pamisomali yosachotsedwa opaleshoni chimakhala ndi 40% urea.Urea ndi chinthu chabwino chonyowetsa, chimakhala mu cuticle ya khungu, ndiye chigawo chachikulu cha NMF pakhungu.
