urea granular ammonium sulphate feteleza
Urea, yomwe imadziwikanso kuti carbamide, ndi diamide ya carbonic acid yokhala ndi formula ya molekyulu ya CO(NH2)2.Amagwiritsidwa ntchito makamaka m'makampani ndi ulimi.M'makampani, urea amawerengera 28.3% ya ntchito: melamine resins, melamine, melamine acid, etc. Itha kugwiritsidwanso ntchito ngati chowonjezera cha chakudya komanso m'makampani opanga mankhwala ndi zodzoladzola.Paulimi, urea amagwiritsidwa ntchito makamaka kupanga feteleza wophatikizika kapena kugwiritsidwa ntchito mwachindunji ngati fetereza, ntchito yaulimi ya Urea imagwiritsa ntchito 70% yakugwiritsa ntchito kwake konse.

Feteleza wa Granular kapena Powder Nitro-sulfur-based NPK 15-5-25 Compost Feteleza
Ndi feteleza wapawiri wokhala ndi ammonium nitrate monga gwero la nayitrogeni, kuwonjezera phosphorous, potaziyamu ndi feteleza zina zopangira feteleza kuti apange feteleza wambiri wa N, P, K.Zogulitsa zake zimakhala ndi nitrate ndi ammonium nitrogen.Zopangira zazikulu ndi ammonium nitrate phosphorous ndi ammonium nitrate phosphorous potaziyamu.Ndi feteleza wofunikira waulimi, makamaka oyenera fodya, chimanga, vwende, masamba, mitengo yazipatso ndi mbewu zina zachuma komanso dothi lamchere ndi madera amtunda wa karst, kugwiritsa ntchito nthaka yamchere ndi madera a karst ndikwabwino kuposa urea.

NPK17-17-17
Miyezo ya feteleza wapadziko lonse imanena kuti feteleza wapawiri wokhala ndi chlorine ayenera kukhala ndi ma chloride ayoni, monga chloride yotsika (yokhala ndi chloride ion 3-15%), sing'anga chloride (yokhala ndi chloride ion 15-30%), high chloride (yokhala ndi chloride ion). 30% kapena kuposa).
Kugwiritsa ntchito koyenera kwa tirigu, chimanga, katsitsumzukwa ndi mbewu zina zakumunda sizowopsa zokha, komanso kumathandizira kukonza zokolola.
Nthawi zambiri, kugwiritsa ntchito feteleza wopangidwa ndi chlorine, fodya, mbatata, mbatata, chivwende, mphesa, beets, kabichi, tsabola, biringanya, soya, letesi ndi mbewu zina zosagwirizana ndi chlorine zimakhudza kwambiri zokolola komanso zabwino. kuchepetsa phindu lachuma la zokolola zoterezi.Pa nthawi yomweyo, chlorine ofotokoza pawiri fetereza m'nthaka kupanga ambiri klorini ion zotsalira, zosavuta chifukwa consolidation nthaka, salinization, alkalinization ndi zina osafunika zochitika, motero kuwonongeka kwa nthaka chilengedwe, kuti mbewu michere mayamwidwe mphamvu. yafupika.
