Kuwongolera feteleza

[Kusintha kwa kuchuluka kwa maluwa] Pofuna kuthana ndi zaka zazikulu ndi zazing'ono za munda wa apulo, kupopera mbewu mankhwalawa 0,5% urea madzi amadzimadzi pa tsamba pamwamba pa masabata 5-6 mutatha maluwa (nthawi yovuta ya kusiyanitsa kwa maluwa a apulo, kukula kwa mphukira zatsopano kumachedwa kapena kuyima, ndi nayitrogeni yomwe ili m'masamba imasonyeza kutsika), kupopera mbewu mankhwalawa kawiri motsatizana, kungathe kuonjezera nitrogen celerate, masamba atsopano a maluwa, kukula kwa masamba atsopano. kusiyanitsa, ndi kupanga duwa kuchuluka kwa chaka chachikulu choyenera.

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

[Mbeu za mpunga] Mu wosakanizidwa umisiri mpunga mbewu kupanga, kuti patsogolo mlingo outcross wa makolo, kuti kuonjezera kupanga mbewu kuchuluka kwa wosakanizidwa mpunga kapena chonde kuchuluka kwa mizere wosabala, kuyesera unachitikira ndi urea m'malo gibberellin, ndi ntchito 1.5% 2% urea pa mimba pachimake siteji ndi woyamba khutu siteji (20% khutu zotsatira, ndi khutu zotsatira osati khutu) onjezerani kutalika kwa mbewu.

[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.
