Urea Urea: kushanda

murimi ose kuedza kuvandudza zvirimwa zvavo, vachishandisa ose fetiraiza. Nhasi, vakawanda ndiyo carbamide (urea) ine makemikari miriwo uye ivhu inotonhorera yokuvirisa pamwe senitrogen-vapfumi.

A Nhoroondo shoma

First urea yakawanikwa 1773 ne musayendisiti French Hillaire Rouelle, asi chete kubva 1828 akatanga kubudisa zvokugadzirwa nevanhu. Zvinobudirira senitrogen fetiraiza carbamide (urea) wakachena chimiro rine kusvika 46% kubva senitrogen, zvazvichanyungudutswa mvura panguva ph yakadzikama uye haisi chepfu kuna zvinomera uye ivhu.

kusunungurwa Form

Urea (carbamide) inogadzirwa-siyana:

• Muchimiro granules duku kuiparadza zvishoma nezvishoma muvhu uye anodzivirira kubva saturation pamusoro senitrogen. Zviri nyore kuti kuvhiringidza nayo nevamwe fetiraiza, kusanganisira Organic.
• The chimiro hurefu soluble mahwendefa zvemapuranga chaiwo Kamudzira, yakadzivirirwa kubva nokukurumidza nemukuparadzwa muvhu, iyo kunotadzisa chirimwa kubva muvhu uye nitration.

Carbamide: Chikumbiro

Field kuedza kuratidza kuti kushandiswa urea sechinhu pre-rokudyara fetiraiza bvumidzwa zvakakwana pamusoro zvose mhando nevhu uye mumamiriro ose zvirimwa. Kana waivako ichi hachisi muduku Achishandisa Ammonium nitrate uye Ammonium sulfate, uye dzimwe nguva, somuenzaniso, wakange abika-podsolic nevhu nounyoro yakakwana uye unodiridzwa serozem, inopa dzakapfuma mbatatisi chirimwa uye muriwo zvirimwa. Senzira pamusoro kupfeka kuti chando zvirimwa kumavambo muchirimo, uye nokuda mutsara zvirimwa uye miriwo nokukurumidza seeding kudzivirira senitrogen kurasikirwa nokuda kwemvura yacho amoniya aumba panguva manyowa pakati fetiraiza. For foliar zvirimwa akataura crystalline musiyano wezvinyorwa biuret tigutsikane 0.2-0.3%.

zvakwakanakira

Izvi senitrogen fetiraiza ane zvakwakanakira pamusoro dzimwe fetiraiza. Urea (carbamide) zvakanaka kunyura tsika, uye panguva yakakwirira yevasungwa (1% mhinduro) anouraya chirimwa uye asingauyi kupisa mashizha. Kana kuwedzera wefodya ne mashizha masero sezvo wose Morekuru, uye zvinogonawo nyura nokuda manyowa pasi Zvakaitwa enzayemu urease kana amoniya chokuumba diamino loop transformations nitrogenous zvinhu. Zvisinei, imwe nekumwisa vakasununguka amoniya ari mudzi mapazi DZEMUNHU DZINODZORA kumera uye Kutumbuka, saka unofanira kuva chaizvo kodzera mukuita urea kuti ivhu panguva yokudyara kana zvakaenzana kuatumira.

kurumbidza

kusanganiswa urea kuti ivhu Asati kwazvo akataura wokuvhenganisa nayo nevamwe yokuvirisa kana nejecha yakaoma. Kana kushandiswa nemazvo, granular urea (carbamide) ndiyo yakanaka senitrogen fetiraiza. Zvose izvi nemhaka zvakanaka ehupfumi chaiko uyewo mukuru zviri senitrogen wayo sezvamunoita. Sezvo zvichibvira kushandisa chero ivhu, uye ine kunobatsirawo chirimwa kukura, kudiwa ichi zvakasikwa fetiraiza inokura pamwe mwaka nerimwe, uye somugumisiro, ayo kugadzirwa inowedzerawo.
