Makadiifeterezakugadzirwa?
Fetereza inogadzirwa nekugadzira kana kuchenesa zvinhu zvakasikwa.Mafetiraiza akajairika anosanganisira nitrogen, phosphorus, uye potashi.Mishonga yefetereza iyi inobva mupetroleum, mineral and natural resources.Nitrogen fetiraiza inogadzirwa nemakemikari reaction ye gaseous ammonia, phosphate fetiraiza inowanikwa nekurapwa kwepanyama uye kemikari yephosphate ore, uye potassium fetiraiza inowanikwa nekurapwa kwepanyama uye kemikari kwepotashi ore.Kune zvakare mafetireza ebiomass, akaita sefetireza yepasi uye manyowa, ayo anobva muzvinhu zvipenyu.
Fetereza yakacheneswa senge phosphorus yematombo, sodium sulfate, uye sodium nitrate, inotorwa zvakananga kubva kumaminerari echisikigo kana kucheneswa nemaitiro emuviri kana makemikari.
Zvinhu zvinokuvadza, zvakadai seammonia nehydrogen sulfide, zvinogona kugadzirwa panguva yekugadzirwa kwefetereza, inoda kurapwa uye kutevedzerwa nemitemo yenyika yekuchengetedzwa kwezvakatipoteredza.Kusarudzwa nekushandiswa kwemafetereza emakemikari zvinoda kutevedzera magadzirirwo evhu uye zvinodiwa nezvirimwa.Kunyanya kushandiswa kuchava nemigumisiro yakaipa pavhu uye zvakatipoteredza.
Pamusoro pezvo, kushandiswa kwefetereza yemakemikari kunodawo kutevedzera huwandu hwefetiraiza hwakatarwa uye nguva yefetiraiza, uye kugadzirisa fetiraiza kunofanirwa kuitwa zvichienderana nerudzi rwevhu, nzvimbo, mamiriro ekunze uye zvimwe zvinhu kuti tive nechokwadi chekuita fetiraiza yakanakisa.Pakuita fetiraiza, nyaya dzakaita seyekufambisa nekuchengetedza dzinofanirwa kutariswa kuti fetereza yemakemikari isasvibisa nharaunda kana kukanganisa hutano hwevanhu.
Pamusoro pezvo, mumakore achangopfuura, kuitira kugadzirisa kukanganisa kwakashata kwefetereza yemakemikari nharaunda uye hutano hwevanhu, nzira inonzi organic Agriculture yakatsanangurwa, iyo inonyanya kuwanikwa kuburikidza nekushandiswa kwefotereza, kuvandudzwa kwevhu, uye kutonga kweminda. .Zvinangwa zvekugadzira zvinobudirira uye zvakatipoteredza.
Pamusoro pezvo, mamwe matekinoroji efotereza ari kugadziridzwa zvakare, senge mafetireza ebiochar, mafetireza tupukanana, nefetereza inobvisa chirimwa.Zvokudya zvinovaka muviri zvinopa mupiro wakagadzikana uye unogara kwenguva refu.
Muchidimbu, mafetereza emakemikari chinhu chakakosha chekudya mukurima, asi kugadzirwa uye kushandiswa kwemafetereza emakemikari kunofanirwa kutarisisa nyaya dzezvehutano uye hutano hwevanhu, uye mhinduro dzakakwana dzinofanirwa kugamuchirwa kuvandudza kurima kwekurima uye kuchengetedza nharaunda hutano hwevanhu panguva imwe chete.
Ndeapi mafetireza mana makuru?
Mafetereza mana makuru anoti nitrogen, phosphorus, potashi uye calcium.
1.Nitrogen fetiraiza: Nitrogen chimwe chezvokudya zvakakosha mukukura kwechirimwa, izvo zvinogona kukurudzira kukura kwedzinde nemashizha emiti.Mafetereza enitrogen anowanikwa anosanganisira ammonia nitrogen fertilizer, ammonium nitrate, urea zvichingodaro.
2.Fosforasi fetireza: Phosphorus chinhu chakakosha chekudyara midzi yezvirimwa uye kuberekana, uye inogonawo kukurudzira kusamira kwechirimwa.Kazhinji phosphate fertilizer zvinosanganisira diammonium phosphate, triammonium phosphate, uye sodium phosphate.
3.Fetereza yePotassium: Potassium chinhu chakakosha chekudyara michero yechirimwa uye kusagadzikana kwekusagadzikana, uye inogona kukurudzira kukura kwemichero yechirimwa nekubereka michero.Kazhinji potassium fertilizer zvinosanganisira potassium chloride uye potassium sulfate.
4.Calcium fetiraiza: Calcium chinhu chakakosha pakugadzikana kwechirimwa sero madziro emadziro uye genetic zvinhu, izvo zvinobatsira zvirimwa kurwisa zvirwere uye kujairana nenharaunda.Kazhinji calcium fertilizer inosanganisira lime uye calcium carbonate.
