Mineral fertilizer - iyi inenge iyo yose tafura yeMendeleev, iyo inodyisa mbeu uye ine inokurumidza uye yakawanda inobatsira mune zvekurima kudarika zvirimwa. Ngationgororei mikuru ye mineral fertilizer uye maitiro avo.
Urongwa hwemamineral fertilizer
Mamiriro ezvinhu, ose emaminerari fertilizer anogona kugoverwa mumapoka makuru maviri:
- nyore;
- yakaoma.
Maererano neshoko iri, mashomanana akareruka ane chimwe chikamu muhutano, yakaoma manyowa ane maviri kana kupfuura.
Zvichienderana nezvinowanikwa mumutumbi mukuru, mineral fertilizer yose yakakamurwa kuva:
1. Nitric - rubatsiro rwekukudziridza chikamu chenyika. Mhando dzose dze nitrogen fertilizer dzinogadziriswa mumvura, dzichiiswa muvhu mwedzi usati watanga gore. Ivo vane mafomu mana:
- nitrate (sodium uye calcium nitrate);
- ammonium (ammonium sulfate);
- amide (urea);
- ammonium nitrate (ammonium nitrate).
2. Phosphoric - tangibly inokurumidza kutanga kwemaruva uye kuisa michero pavari. Izvo zvinoitwa muvhuvhu kana kutanga kwemvura panguva yekuchera. Nguva yekuparara kwemajeri akadaro imwe chete nehafu kusvika mwedzi miviri, iyo haina kunyanya kusanganiswa mumvura. Mhando dzinonyanyozivikanwa dzephosphoric mineral fertilizer ndezotevera:
- nyore superphosphate;
- kaviri superphosphate;
- phosphorite ufa.
3. Potashi - kukurudzira kukura kwezvibereko zvekurima uye kuwedzera kusagadzikana kwezvirwere, kuvandudza kutarisa kwemichero uye kuwedzera upenyu hwemafuro. Zvose zvinokonzera mashokita zvinoshandiswa zvakakwana mumvura. Iyo inowanzoshandiswa mumhando yakachena, iyo inowanzobatanidzwa ne nitrogen, phosphorus uye dzimwe microelements. Zviyo zvinowanzojairika zvakagadzirwa ne potassium:
- potassium munyu;
- potassium chloride;
- potassium sulphate.
Mineral fertilizer inosanganisira mikuru yakawanda:
- ammophos;
- nitroammophoska;
- diammofosca;
- nitrophosphate .
Kushandiswa kwemamineral fertilizer
Chinhu chinonyanya kukosha munyaya iyi inyanzvi yekuverenga kwekushandiswa kwemuti wemamineral fertilizer. Inofanira kubudiswa ichifungisisa kuiswa kwezvinhu zvinoshanda uye mazano ekugadzirwa kwezvinhu kune imwe mbeu.
Mukuwedzera, mune dzimwe nguva inobatsira kushandisa mvura yemamineral fertilizer nokuda kwekushandiswa kwemafiliar kumusoro kupfeka kwemiti. Uye dzimwe mhando yemamineral fertilizer, somuenzaniso, urea, inoshandiswa nenzira yekugadzirisa uye yemidziyo yekugadzira midzi, sezvo nitrogen kana yakanyungurwa mumvura zviri nani zvakagadzirirwa muvhu.
