Diammonium phosphate: kushandiswa uye zvivakwa
Tichiunza yedu yemhando yepamusoro yeDiammonium Phosphate (DAP), fetereza ine zvinangwa zvakawanda yakakosha mukukura nekusimudzirwa kwembesa dzakasiyana. DAP ifetireza inonyungudika zvikuru iri nyore kushandisa uye inoita kuti maonda mashoma anosiiwa mushure mekupera. Ichi chivakwa chinoita kuti chive chakanakira kusangana nenitrogen uye phosphorus zvinodiwa zvemhando dzakasiyana dzezvirimwa.
Diammonium phosphateinzvimbo yakakosha yenitrogen uye phosphorus, zvinhu zviviri zvakakosha zvakakosha pakukura kwechirimwa chine hutano. Inonyanya kubatsira mukusimudzira kukura kwemidzi, kuvandudza maruva uye fruiting, uye kuwedzera goho rose rezvirimwa. DAP ine yakanakisa kunyungudika kwemvura uye inonyudzwa zviri nyore nezvirimwa, kuve nechokwadi chekunyura kwakanaka uye kushandiswa kwezvinovaka muviri.
DAP yedu inogadzirwa kune yepamusoro-soro, kuve nechokwadi chekuchena kwayo uye kushanda kwayo. Isu tinotarisira zvakanyanya panguva yekugadzira kuti tive nechokwadi chekuti zvigadzirwa zvedu zvinosangana nezvinodiwa zvekurima kwemazuva ano.

Diammonium phosphate munyu muchena wecrystalline une kunyungudika kwakanyanya mumvura. Iyo inonzi hygroscopic, zvichireva kuti inotora nyore hunyoro kubva mumhepo. Iyi pfuma inoita kuti ive yakakosha kuchengeta DAP munzvimbo yakaoma kudzivirira clumping uye kuchengetedza kushanda kwayo.
Imwe yemabhenefiti makuru eDAP ndeye yakakwira chikafu chemukati, ichipa zvirimwa zvakakosha phosphorus uye nitrogen. Inoshandiswa zvakasiyana-siyana uye inogona kushandiswa seyese uye yepamusoro yekupfeka. Pamusoro pezvo, yakaderera pH yeDAP inobatsira kuderedza alkalinity yevhu uye inovandudza kutora kwechirimwa kwekudya.
Nepo DAP ichipa mabhenefiti akawanda, zvakakoshawo kufunga zvingango kanganisa. Kunyanya kushandiswa kwediammonium phosphatezvinogona kukonzera kusagadzikana kwekudya kwevhu uye zvinogona kukuvadza zvakatipoteredza. Pamusoro pezvo, chimiro chayo che hygroscopic chinoda kungwarira kubata uye kuchengetedza kuchengetedza mhando yayo.
- Kana huwandu hwephosphorus huchidzokororwa pamwe chete nenitrogen: semuenzaniso pakukura kwemidzi panguva yekutanga mumwaka wekukura;
- Inoshandiswa pakudya kwefoliar, fertigation uye sechinhu muNPK; -Iyo inoshanda zvakanyanya sosi yephosphorus nenitrogen;
- Inoenderana neakawanda mafetireza anonyungudika mumvura.
Diammonium phosphate (DAP) inoshandiswa zvakanyanya inorganic munyu ine kemikari formula (NH4)2HPO4. Nekuda kwekuita kwayo kwakasiyana uye maitiro, ine mukurumbira nekuda kwehuwandu hwayo hwekushandisa mumaindasitiri akasiyana. DAP haina ruvara yakajeka monoclinic crystal kana chena poda. Inonyungudika zviri nyore mumvura asi kwete mudoro, zvichiita kuti ive chinhu chiri nyore uye chinoshanda chekushandisa kwakawanda.
Diammonium phosphate inoshandiswa zvakanyanya muanalytical chemistry, kugadzira chikafu, kurima nekupfuya mhuka. Hurukuro hwayo hwekushandisa hunoita kuti ive musanganiswa unokosha mumhando dzakasiyana siyana dzeindasitiri nekutengesa.
Mundima yekuongorora chemistry, diammonium phosphate inoshandiswa se reagent mune dzakasiyana siyana dzekuongorora maitiro. Kunyungudika kwayo mumvura uye kuenderana nezvimwe zvinhu zvinoita kuti ive yakanakira kuongororwa kwemakemikari uye kuyedza. Kuchena kwekomboni uye kuenderana kunoita kuti ive chinhu chakavimbika mumarabhoritari.
Muindasitiri yekugadzira chikafu, DAP inoita basa rakakosha sekuwedzera kwechikafu uye chikafu chekuwedzera. Inowanzoshandiswa sechinhu chinovirisa mukubika, chinobatsira kugadzira carbon dioxide, iyo inogadzira chiedza chakajeka, chine airy muzvinhu zvakabikwa. Pamusoro pezvo, diammonium phosphate inoshandiswa sechitubu chenitrogen uye phosphorus mukusimbisa chikafu, zvichibatsira kuwedzera kukosha kwekudya kwechikafu chakagadzikiswa.
Zvekurima nekupfuya zvipfuyo zvinobatsira zvikuru kubva mukushandiswa kwediammonium phosphate. Sefotereza,DAPinopa kudya kwakakosha kuzvirimwa, kukurudzira kukura kune hutano uye kuwedzera goho rezvirimwa. Kunyungudika kwayo kwakanyanya kunogonesa kubatwa kwezvinovaka muviri nezvirimwa, zvichiita kuti ive sarudzo inoshanda yezvekurima. Pamusoro pezvo, DAP inoshandiswa mukuumbwa kwechikafu chemhuka kusimudzira zvinovaka muviri uye kutsigira hutano hwezvipfuyo uye kugara zvakanaka.
Imwe yemhando dzakakurumbira dzediammonium phosphate iDAP pellets, iyo inopa nyore kubata uye kushandisa mumhando dzakasiyana dzekurima. DAP pellets inopa kuburitswa kwakasimba kwezvinovaka muviri, zvichiita kuti zvikodzere kushandiswa muzvirongwa zvefetiraiza yezvirimwa zvakasiyana.
Muchidimbu, diammonium phosphate ikomboni yakakosha ine akawanda maapplication mumaindasitiri akasiyana. Kunyungudika kwayo, kuenderana uye zvinovaka muviri zvinoita kuti ive chinhu chakakosha mukuongorora chemistry, kugadzira chikafu, kurima nekupfuya mhuka. Ingave iri muchimiro chekristasi, hupfu kana granules, DAP inoramba iri chinhu chakakosha chinobatsira kufambisira mberi nekubudirira kweakasiyana maitiro uye zvigadzirwa.

Q1. Diammonium phosphate inokodzera marudzi ese ezvirimwa here?
DAP yakakodzera zvirimwa zvakasiyana, kusanganisira izvo zvinoda nitrogen-neutral phosphorus.
Q2. Nzira yekushandisa sei diammonium phosphate?
DAP inogona kushandiswa nenzira dzakasiyana-siyana, dzinosanganisira kutepfenyura, mitsetse uye fertigation, zvichienderana nezvinodiwa chaizvo zvechirimwa nevhu.
Q3. Ko diammonium phosphate inogona kushandiswa mukurima organic here?
Kunyange zvazvo DAP isingaonekwi sefotereza yepasi, inowanzoshandiswa mukurima kwakajairika kupa chikafu chakakosha kuzvirimwa.
