Diammonium phosphate: ntchito ndi katundu
Tikubweretsa feteleza wathu wapamwamba kwambiri wa Diammonium Phosphate (DAP), wopangidwa ndi ntchito zambiri wofunikira pakukula ndi kukula kwa mbewu zosiyanasiyana. DAP ndi feteleza wosungunuka kwambiri yemwe ndi wosavuta kugwiritsa ntchito ndipo amaonetsetsa kuti zolimba zochepa zimasiyidwa pambuyo pa kusungunuka. Katunduyu amapangitsa kuti ikhale yabwino kukwaniritsa zosowa za nayitrogeni ndi phosphorous za mbewu zosiyanasiyana.
Diammonium phosphatendi gwero lamtengo wapatali la nayitrogeni ndi phosphorous, michere iwiri yofunika kwambiri kuti mbewu ikule bwino. Zimathandiza kwambiri kulimbikitsa kukula kwa mizu, kukulitsa maluwa ndi fruiting, ndi kuonjezera zokolola zonse. DAP ili ndi kusungunuka kwabwino kwambiri m'madzi ndipo imatengedwa mosavuta ndi zomera, kuonetsetsa kuti mayamwidwe ndi kugwiritsa ntchito zakudya zoyenera.
DAP yathu imapangidwa mwapamwamba kwambiri, kuwonetsetsa kuti ikhale yoyera komanso yogwira mtima. Timasamala kwambiri pakupanga zinthu kuti titsimikizire kuti zogulitsa zathu zikukwaniritsa zofunikira zaulimi wamakono.

Diammonium phosphate ndi mchere woyera wa crystalline womwe umasungunuka kwambiri m'madzi. Ndi hygroscopic, kutanthauza kuti imatenga chinyezi kuchokera mumlengalenga. Katunduyu amapanga kukhala kofunikira kusungirako DAP pamalo owuma kuti apewe kuphatikizika ndikusunga mphamvu zake.
Ubwino wina waukulu wa DAP ndi kuchuluka kwake kwa michere, kupatsa zomera zofunika phosphorous ndi nayitrogeni. Ndizosunthika ndipo zitha kugwiritsidwa ntchito ngati zovala zoyambira komanso zapamwamba. Kuonjezera apo, pH ya DAP yotsika imathandizira kuchepetsa kusungunuka kwa nthaka komanso kumapangitsa kuti zomera zisamadye zakudya.
Ngakhale kuti DAP imapereka maubwino ambiri, ndikofunikiranso kuganizira zovuta zomwe zingachitike. Kugwiritsa ntchito kwambiri kwadiamondi phosphateZingayambitse kusalinganika kwa michere ya m'nthaka ndipo zingakhale zovulaza chilengedwe. Kuphatikiza apo, chikhalidwe chake cha hygroscopic chimafunika kugwiridwa mosamala ndikusungidwa kuti chisungike bwino.
- Pamene misinkhu phosphorous reguired osakaniza nayitrogeni: mwachitsanzo kwa mizu kukula pa nthawi ya kukula nyengo;
- Amagwiritsidwa ntchito podyetsa masamba, kuthirira komanso ngati chophatikizira mu NPK; - Gwero lothandiza kwambiri la phosphorous ndi nayitrogeni;
- Yogwirizana ndi feteleza ambiri osungunuka m'madzi.
Diammonium phosphate (DAP) ndi mchere wogwiritsidwa ntchito kwambiri ndi mankhwala opangidwa ndi mankhwala (NH4)2HPO4. Chifukwa cha ntchito yake yapadera komanso mawonekedwe ake, ndi yotchuka chifukwa cha ntchito zake zosiyanasiyana m'mafakitale osiyanasiyana. DAP ndi kristalo wopanda mtundu wowonekera wa monoclinic kapena ufa woyera. Amasungunuka mosavuta m'madzi koma osati mowa, zomwe zimapangitsa kuti zikhale zosavuta komanso zogwira ntchito zambiri.
Diammonium phosphate imagwiritsidwa ntchito kwambiri pofufuza chemistry, kukonza chakudya, ulimi ndi kuweta ziweto. Kugwiritsidwa ntchito kwake kosiyanasiyana kumapangitsa kukhala kofunikira kwambiri pamachitidwe osiyanasiyana amakampani ndi malonda.
M'munda wa chemistry yowunikira, diammonium phosphate imagwiritsidwa ntchito ngati reagent munjira zosiyanasiyana zowunikira. Kusungunuka kwake m'madzi ndi kugwirizana ndi zinthu zina kumapangitsa kuti zikhale zoyenera kusanthula mankhwala ndi kuyesa. Kuyera kwapawiri ndi kusasinthika kumapangitsa kuti ikhale yodalirika popanga ma labotale.
M'makampani opanga zakudya, DAP imagwira ntchito yofunika kwambiri ngati chowonjezera chazakudya komanso chopatsa thanzi. Nthawi zambiri amagwiritsidwa ntchito ngati chotupitsa pophika, kuthandizira kupanga mpweya woipa, womwe umapanga kuwala, mpweya wabwino muzophika. Kuphatikiza apo, diammonium phosphate imagwiritsidwa ntchito ngati gwero la nayitrogeni ndi phosphorous pakulimbitsa chakudya, zomwe zimathandiza kukulitsa thanzi lazakudya zosinthidwa.
Ulimi ndi ziweto zimapindula kwambiri pogwiritsa ntchitodiamondi phosphate. Ngati feteleza,DAPamapereka michere yofunika kwa zomera, kulimbikitsa kukula bwino ndi kuonjezera zokolola. Kusungunuka kwake kwakukulu kumapangitsa kuti zomera zizitha kudya bwino, zomwe zimapangitsa kukhala chisankho chabwino pazaulimi. Kuonjezera apo, DAP imagwiritsidwa ntchito popanga zakudya za ziweto kuti zikhale ndi thanzi labwino komanso kuthandizira thanzi la ziweto.
Chimodzi mwazinthu zodziwika bwino za diammonium phosphate ndi ma pellets a DAP, omwe amapereka mosavuta kugwiritsa ntchito komanso kugwiritsa ntchito njira zosiyanasiyana zaulimi. Ma pellets a DAP amapereka kumasulidwa kosalekeza kwa michere, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pamapulogalamu a umuna wa mbewu zosiyanasiyana.
Mwachidule, diammonium phosphate ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kusungunuka kwake, kugwirizana kwake komanso zakudya zomwe zili ndi zakudya zimapangitsa kuti zikhale zofunikira kwambiri pa kafukufuku wamankhwala, kukonza zakudya, ulimi ndi kuweta nyama. Kaya mu mawonekedwe a makhiristo, ufa kapena granules, DAP imakhalabe chinthu chofunika kwambiri chomwe chimathandizira kupititsa patsogolo ndi kuyendetsa bwino njira zosiyanasiyana ndi mankhwala.

Q1. Kodi diammonium phosphate ndiyoyenera kubzala zamitundu yonse?
DAP ndiyoyenera ku mbewu zosiyanasiyana, kuphatikiza zomwe zimafunikira phosphorous-neutral nitrogen.
Q2. Momwe mungagwiritsire ntchito diamondi phosphate?
DAP ingagwiritsidwe ntchito ndi njira zosiyanasiyana, kuphatikizapo kuwulutsa, kukwapula ndi kuthirira, malingana ndi zofunikira za mbewu ndi nthaka.
Q3. Kodi diammonium phosphate ingagwiritsidwe ntchito pa ulimi wa organic?
Ngakhale kuti DAP samatengedwa ngati feteleza wachilengedwe, amagwiritsidwa ntchito m'njira zaulimi wamba kuti apereke zakudya zofunika ku mbewu.
