1. Isai manyowa zvichienderana nemamiriro chaiwo evhu nezvirimwa
Huwandu nekusiyana kwefotereza zvakatarwa zvine mutsindo zvichienderana nekuorera kwevhu, kukosha kwePH, uye maitiro efotereza inodiwa pazvirimwa.
2. Sanganisa nitrogen, phosphorus, potassium, organic fertilizer, uye micronutrient fertilizer
Iko kusanganiswa-kushandiswa kwezvinhu zvakawanda uyeorganic fetereza or manyowainogona kuderedza adsorption nekugadzirisa phosphorus muvhu uye kuwedzera chiyero chekushandiswa kwefetereza.Zvichienderana nezvirimwa zvakasiyana, 6-12 kg yefetireza yemicronutrient yakaiswa paAcre yega yega.
3. Kushandisa kwakadzika, kushandiswa kwakanyanyisa, uye kushandiswa kwakaiswa
Deep application inzira yakakosha yekuwedzera nitrogen kushandisa kunyatsoita uye kuderedza nitrogen kurasikirwa, iyo isingangogone kuderedza ammonia volatilization asi zvakare kuderedza denitrification kurasikirwa, kune rumwe rutivi, kuderedza makemikari kugadzirisa kunogona kuwedzera mutsauko wekusangana nemidzi yezvirimwa uye kukurudzira kutora phosphorus nezvirimwa.Mukuwedzera, kufamba kwephosphorus muvhu kwakashata.
4. Shandisai fetereza inononoka kubuda
Zvinozivikanwa kuti kushandiswa kwefotereza inononoka kuburitsa kunogona kuderedza huwandu hwefetireza uye kuvandudza huwandu hwekushandisa.Mhedzisiro yefotereza inononoka kuburitsa yakareba kupfuura mazuva makumi matatu, kurasikirwa kweleaching volatilization kunoderedzwa, uye huwandu hwefetireza hunogona kuderedzwa ne10% -20% kupfuura iyo yenguva dzose fetiraiza.Panguva imwecheteyo, kushandisa fetereza inononoka kuburitsa kunogona kuwedzera goho nemari.Mushure mekushandiswa, mugumisiro wefetiraiza wakagadzikana uye wakareba, nguva yekupedzisira haina kupera, inodzivirira zvirwere, uye inodzivirira pokugara, uye goho rinogona kuwedzera kupfuura 5%.
5. Formula fertilization
Ongororo iyi yakaratidza kuti huwandu hwemashandisirwo efetereza hunogona kuwedzerwa ne5% -10%, fetireza yebofu inogona kudzivirirwa uye kutambisa fetereza kunogona kudzikiswa.Mukukosha kwakazara, huwandu hwenitrogen yakatorwa nezvirimwa, huwandu hwefetireza yasara muvhu, uye huwandu hwefetireza yakarasika hwakawedzera nekuwedzera kwehuwandu hwenitrogen fetireza yakaiswa, nepo mukukosha, kushandiswa kwenitrogen kwakadzikira kuwedzera kwehuwandu hwefetireza yakaiswa, chiyero chekurasikirwa chakawedzera nekuwedzera kwekuisa fetereza.
6. Ishandise panguva chaiyo
Iyo nguva yakakosha yekudya uye yakanyanya kushanda nguva inguva mbiri dzakakosha kuti zvirimwa zvitore chikafu.Tinofanira kubata nguva mbiri idzi kuti tive nechokwadi chekushanda zvakanaka kwefetereza uye kudiwa kwekudya kunovaka zvirimwa.Kazhinji, nguva yakaoma ye phosphorus iri mu prophase yekukura, uye nguva yakaoma ye nitrogen inononoka zvishoma pane iyo phosphorus.Iyo yakanyanya kunaka nguva inguva kubva pakukura kwezvinomera kusvika pakukura kwekubereka.
