Wolemera superphosphate mu feteleza
TSP ndi feteleza wa phosphate wosungunuka kwambiri, wosasungunuka m'madzi, ndipo phosphorous yomwe ili nayo ndi 2.5 mpaka 3.0 kuposa calcium wamba (SSP). Mankhwalawa atha kugwiritsidwa ntchito ngati feteleza wapansi, chokokera pamwamba, feteleza wa mbeu ndi zipangizo zopangira feteleza pawiri; amagwiritsidwa ntchito kwambiri mu mpunga, tirigu, chimanga, manyuchi, thonje, zipatso, masamba ndi mbewu zina za chakudya ndi mbewu zachuma; amagwiritsidwa ntchito kwambiri mu nthaka yofiira ndi nthaka yachikasu , nthaka ya Brown, nthaka yachikasu ya fluvo-aquic, nthaka yakuda, nthaka ya sinamoni, nthaka yofiirira, nthaka ya albic ndi makhalidwe ena a nthaka.
Katatu superphosphate (TSP)ndi feteleza wa phosphate wosungunuka kwambiri m'madzi wopangidwa kuchokera ku asidi wa phosphoric wosakanikirana ndi thanthwe la phosphate. Chopangidwa ndi njirayi chimagwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana ya dothi. Ubwino umodzi waukulu wa TSP ndi kusinthasintha kwake, chifukwa ukhoza kugwiritsidwa ntchito ngati feteleza woyambira, kuvala pamwamba, feteleza wa majeremusi, komanso ngati zopangira zopangira feteleza wambiri.
Kuchuluka kwa phosphate mu TSP kumapangitsa kuti ikhale njira yabwino komanso yothandiza polimbikitsa kukula kwa mbewu ndikuwonjezera zokolola. Kusungunuka kwake m'madzi kumatanthauzanso kuti imatengedwa mosavuta ndi zomera, kuwapatsa zakudya zofunikira zomwe zimafunikira kuti chitukuko chikhale bwino. Kuphatikiza apo,Mtengo wa TSPamadziwika kuti amatha kukonza nthaka yabwino, ndikupangitsa kuti ikhale njira yofunikira kwa alimi ndi alimi omwe akufuna kuwonjezera chonde m'munda wawo.
Kuphatikiza apo, TSP ndi njira yotsika mtengo yothanirana ndi vuto la phosphorous m'nthaka, ndikupangitsa kukhala chisankho chodziwika bwino pakati pa akatswiri azaulimi. Kuthekera kwake kumasula zakudya pang'onopang'ono pakapita nthawi kumathandizanso kuti mbewuyo ikhale ndi nthawi yayitali, ndikuwonetsetsa kuti mbewuyo ikupitilizabe kupindula m'moyo wake wonse.
Kutengera njira yachikhalidwe yamankhwala (Den njira) yopanga.
Phosphate rock powder (slurry) amakumana ndi sulfuric acid kuti asiyanitse zolimba zamadzimadzi kuti apeze njira yonyowa yochepetsera asidi wa phosphoric. Pambuyo ndende, anaikira phosphoric asidi analandira. Phosphoric acid ndi phosphate thanthwe ufa zimasakanizidwa (mankhwala opangidwa ndi mankhwala), ndipo zinthu zomwe zimapangidwira zimayikidwa ndikukhwima, granulated, zouma, zosefa, (ngati kuli kofunikira, phukusi lotsutsa-caking), ndi kuzizidwa kuti mupeze mankhwala.
1. Ubwino wina waukulu wa TSP ndi kuchuluka kwa phosphorous, yomwe imapatsa mbewu michere yofunika kuti ikule bwino. Phosphorus ndiyofunikira pakukula kwa mizu, maluwa ndi zipatso, zomwe zimapangitsa TSP kukhala chida chofunikira kwa alimi ndi alimi omwe akufuna kukulitsa zokolola.
2 . TSP imapangidwa pophatikiza phosphoric acid yokhazikika ndi thanthwe la phosphate ndipo ndi feteleza wamphamvu yemwe amagwiritsidwa ntchito kwambiri paulimi. Kusungunuka kwake kwakukulu kumapangitsa kuti ikhale yabwino kusankha mitundu yosiyanasiyana ya dothi ndipo itha kugwiritsidwa ntchito ngati feteleza woyambira, kuvala pamwamba, feteleza wa majeremusi ndi majeremusi.feteleza wambirikupanga zopangira.
3 . Kuphatikiza apo, TSP imadziwika chifukwa cha kuthekera kwake kukonza chonde komanso kapangidwe ka nthaka. Popereka gwero lopezeka mosavuta la phosphorous, limathandiza kuchulukitsa michere yonse m'nthaka, kulimbikitsa kukula kwa zomera ndi kupirira. Izi ndizopindulitsa makamaka ku dothi lomwe lilibe phosphorous, chifukwa TSP imatha kuthandiza kukonza kusalinganika kwa michere ndikuthandizira kukolola bwino kwa mbewu.
4 . Kuonjezera apo, chikhalidwe cha TSP chosungunuka m'madzi chimapangitsa kuti chikhale chosavuta kugwiritsa ntchito komanso kutengeka mwamsanga ndi zomera, kuonetsetsa kuti zakudyazo zikupezeka nthawi yomweyo. Izi ndizopindulitsa makamaka pamene kusowa kwa phosphorous kuyenera kukonzedwa mwamsanga kapena poyang'ana kukula kwa zomera.
