Nitrojeni semudziro wezvokudya zvinokonzerwa zvinowanzoitika muvhu, asi munzvimbo dzakasiyana-siyana dzemamiriro okunze kuwanikwa kwevhu kune zvakasiyana. Zvinoshamisa zvinonzi nitrogen zvishoma mumapapu echando uye sandy loamy ivhu. Mukuwedzera, 1% chete yezvinhu izvi inowanika kumiti, saka zvakakosha kuti nguva nenguva dzive inovandudza ivhu ne nitrogen fertilizers, uye ndeapi marangi achakurukurwa munyaya ino.
Kukosha kwe nitrogen fertilizer yemiti
Yakakwirira-grade nitrogen chikafu kwete chete inobatsira pazvibereko, asi inowedzerawo kunaka kwezvirimwa zvakadyarwa. Somugumisiro wekuwedzera huwandu hweprotini uye kuwedzera kuwanda kwemapuroteni anokosha, miti yakadyarwa inotanga kukura nekukurumidza, mashizha avo anoonekwa nehukuru hwakaoma ruvara rwemavara, uye michero yakawanda mukukura. Kana nitrogen isingakwanisi, ipapo pane-pane imwe nzvimbo pane zvishoma chlorophyll uye mashizha anokura maduku, kurasikirwa nemuvara, uye zvibereko zvinowira. Tambudzika kubva kuproteine kukwana uye mbeu. Saka, zvakakosha zvikuru kugadzira zvigadziro zvekuvandudza kwezvirimwa, zvichipa ivhu nehuwandu hunokosha hwe nitrogen.
Organic nitrogen fertilizers
Dzinosanganisira:
- Mhando dzose dzemvura, madonhwe emhashu, kunyanya dha, huku uye njiva.
- Compost piles. Nhamba shoma ye nitrogen inowanikwa mumisungo uye kubva mumarara emisha.
- Green mass. Inowanikwawo mumashizha, ichi silt, lupine, sweet clover, vetch, clover, nezvimwewo.
Nitrogen mineral fertilizers
Avo vanobvunza kuti ndeapi mazita e nitrogen fertilizer, zvakakosha kuti titeerere kune urongwa urwu:
- Ammonium fertilizer ammonium sulfate, ammonium chloride.
- Nitrate fertilizer is calcium uye sodium nitrate.
- Amide fertilizer urea .
Izvi ndizvo zvinoshanda kune nitrogen fertilizer. Paunotenga iwe unogona kuwana nekugadzira, iyo ine nitrogen imwechete mu nitrate uye ammonia fomu. Mukuwedzera, zvakakosha kuziva kuti nitrogen fertilizer inoshandiswa pamwe chete ne phosphorus uye potassium fertilizer. Izvo zvinodiwa zvinosangana ne superphosphate, bone kana kuti dolomite ufa, ammonium nitrate. Iyo yekupedzisira inoshandiswa panzvimbo dzisina kusimba humidified nehuwandu hwevhu hwechinangwa. Inowanzosanganiswa ne superphosphate uye neutralizing agent. Izvi zvinotarisa rudzi rwezvirimwa zvakasimwa, nokuti dhigiri uye nzira yekufananidzwa kwe nitrogen mavari yakasiyana.
Pakawanda mune zvemabhizimisi, mvura inoshandiswa nitrogen fertilizer inoshandiswa, iyo inoshandiswa zvakafanana, inogadzirirwa zvakanaka uye inoshandiswa kwenguva yakareba. Zvisinei, nitrogen yakakwana inopa michero inogona kugadziriswa chete nekushandiswa kwehutano hwehupenyu uye hwemineral fertilizer.
