Ntchito:Feteleza wosakanikirana bwino. Oyenera ngati feteleza wofesa mbewu, feteleza m'munsi kapena zovala zapamwamba.

Maonekedwe a superphosphate yolemera amafanana ndi calcium wamba, nthawi zambiri imvi yoyera, imvi kapena yakuda. Feteleza wochulukidwa nthawi zambiri amakhala granule wa 1-5 wokhala ndi makulidwe ochuluka pafupifupi 1100 kg / m. Gawo lalikulu la superphosphate lolemera ndi monocalcium phosphate monohydrate.

Popeza chuma cha phosphoric acid ndi thanthwe la phosphate chimakhala ndi zosayera, mankhwalawa amakhalanso ndi zina zochepa. Gulu lonse la calcium phosphate yolemera kwambiri padziko lonse lapansi ndi N-P2o5-K2O: 0-46-0. Makampani aku China omwe amapanga zinthu zolemera kwambiri za superphosphate, HG2219-9l, amati: P2O5 ≥ 38% ya superphosphate ndi yoyenera, ndipo P2 ≥ 46% ndiyabwino.

Granular heavy superphosphate itha kugwiritsidwa ntchito mwachindunji kapena ngati phosphorous zopangira feteleza. Mafuta a granular super-superphosphate atha kugwiritsidwa ntchito ngati mankhwala apakatikati ndi ena a nayitrogeni kapena potaziyamu opangira feteleza oyambira kapena kutsata zinthu zopangira zomwe zimasinthidwa kukhala feteleza wokhala ndi michere yambiri kukwaniritsa zosowa za dothi ndi mbewu zosiyanasiyana. .

Ubwino wa superphosphate yolemera kwambiri ndi kuchuluka kwa michere, ndipo yambiri ndi phosphorous yosungunuka m'madzi, yomwe imasungira ndalama zonyamula ndi zoyendera ndikuchepetsa mtengo wam'munda. Chifukwa chake, kupanga chida cholemera kwambiri cha superphosphate pamalo opangira miyala ya phosphate ndizochuma kwambiri komanso zomveka.

Ubwino winanso wazogulitsa ndikuti P2O5 yomwe ili mgulitsidweyi imasinthidwa kuchokera ku thanthwe lotsika mtengo. Ndiye kuti, P2O5 yothandiza kwambiri imatha kupezeka popanga kuchuluka kwa phosphoric acid kuti ipange superphosphate yolemera kuposa kutulutsa phosphate ya ammonium.

Kashiamu yolemera kwambiri imawonjezera kukolola pazinthu zambiri monga tirigu, mpunga, soya, chimanga, waluso, ndi zina zambiri, monga: zitha kulimbikitsa kukhwima kwa mpunga, kukulitsa kulima, kukula mwamphamvu, zimayambira, kulowera koyambirira, ndikuchepetsa kutseguka; Limbikitsani kukula ndi kukhwima koyambirira kwa mbande za chimanga, ndikulimbikitsa kutalika kwa chomera, kulemera kwa khutu, nambala ya tirigu pachitsulo chilichonse, ndi kulemera kwa tirigu 1000 kulimbikitsa kukula kwa tirigu m'nyengo yamadzi osefukira, mbewu zolimba, kulimbikitsa kulima, ndikukhala ndi zotsatira zowonekera zokolola; Sikuti imangokhala ndi michere yabwino m'nthaka, imathandizanso kukulitsa mizu, imachulukitsa mizu, komanso imawonjezera nayitrogeni. Inde, 1, yogwiritsidwa ntchito pakati, 2, yosakanikirana ndi fetereza, 3, magwiridwe antchito, 4, muzu wakunja.

Ndi feteleza wothamanga kwambiri wa phosphate feteleza, womwe ndi feteleza wosasungunuka ndi madzi wokhala ndi nthawi yayitali kwambiri.Imapereka kwambiri phosphorous ya calcium ndi calcium kulimbikitsa kumera, kukula kwa mizu, kukula kwa mbewu, nthambi, zipatso ndi kusasitsa .

Itha kugwiritsidwa ntchito ngati zopangira feteleza woyambira, feteleza wa mbewu, feteleza wapamwamba, kupopera masamba komanso kupanga feteleza pakompyuta. Itha kugwiritsidwa ntchito yokha kapena kusakanikirana ndi michere ina. Ngati iphatikizidwa ndi feteleza wa nayitrogeni, imatha kukonza nayitrogeni.

Amagwiritsidwa ntchito kwambiri ngati mpunga, tirigu, chimanga, manyuchi, thonje, maluwa, zipatso, ndiwo zamasamba ndi mbewu zina za chakudya ndi mbewu zachuma.

P ndi S yotsika mtengo m'malo osiyanasiyana odyetserako ziweto komanso kubzala. SSP ndichikhalidwe chokomera P ndi S kumalo odyetserako ziweto, ndiwo michere ikuluikulu iwiri yofunikira popanga msipu. Gwero la P posakanikirana ndi N ndi K pazosiyanasiyana zamasamba ndi msipu. Nthawi zambiri imasakanizidwa ndi Sulphate wa Ammonia ndi Muriate wa Potash, koma imatha kuphatikizidwa ndi feteleza wina.

P ndi S yotsika mtengo m'malo osiyanasiyana odyetserako ziweto komanso kubzala. SSP ndichikhalidwe chokomera P ndi S kumalo odyetserako ziweto, ndiwo michere ikuluikulu iwiri yofunikira popanga msipu. Gwero la P posakanikirana ndi N ndi K pazosiyanasiyana zamasamba ndi msipu. Nthawi zambiri imasakanizidwa ndi Sulphate wa Ammonia ndi Muriate wa Potash, koma imatha kuphatikizidwa ndi feteleza wina.

- TSP  ali ndi P wapamwamba kwambiri wa feteleza wouma wopanda N. Kuposa 80% ya P yonse ndiyosungunuka ndi madzi, imapezeka mwachangu kuti imere mbewu, yopititsa patsogolo maluwa ndi zipatso ndikukweza zipatso za masamba

- TSP ilinso ndi 15% ya calcium (Ca), kupereka michere yowonjezera yazomera.

- TSP ndi ya feteleza wa asidi, imagwiritsidwa ntchito munthaka yamchere komanso nthaka yopanda ndale, yabwino kusakanikirana ndi manyowa olima, kukonza nthaka ndikulimbikitsa michere.

Katatu superphosphate (Total P2O5: 46%)

Feteleza woimiridwa ngati 0-46-0, nthawi zambiri amagwiritsidwa ntchito pomwe mbewu zimabzalidwa m'nthaka yocheperako kapena ya phosphorous. Kufunika kwake kumatha kuyerekezedwa ndikosazindikira kapena kuti, mizu imangokhala yofooka, kukula kumakhazikika, kutsika kwa zipatso, masamba kapena m'mbali mwa masamba amasanduka ofiirira komanso mu mbewu monga fodya ndi thonje, masamba amasandulika mtundu wobiriwira wakuda; Mitengo ya mbatata imakhala ndi mawanga abulauni etc.

Chifukwa ndi feteleza wokhala ndi acidic pang'ono, zotsatira zake zimakhala zochepa panthaka yopanda ndale kapena ya alkali. Chifukwa phosphorous yomwe imapangidwa imasungunuka mosavuta m'madzi, imawonetsa zotsatira zake mwachangu. TSP imagwiritsidwa ntchito ngati feteleza woyambira.

Ngati yagwiritsidwa ntchito molawirira kwambiri, fosforasi mmenemo imaphatikizana ndi laimu ndi zinthu zina m'nthaka ndipo imatha mphamvu. Ngati imagwiritsidwa ntchito mutabzala kapena kubzala, imakhalabe pamtunda ndipo imakhala ndi zotsatira zochepa. Pazifukwa izi, iyenera kugwiritsidwa ntchito nthawi iliyonse kapena mutangobzala, kubzala kuti zitheke bwino.

Mtundu wa feteleza wosungunuka mwachangu wamadzi.

Amagwiritsidwa ntchito kwambiri ngati zopangira feteleza wa Blending NPK.

TSP imakhala ndimadzi ambiri osungunuka amadzi omwe amatha kusintha kukula kwa zomera kapena matupi, kukulitsa mizu komanso kuthana ndi tizilombo.

TSP itha kugwiritsidwa ntchito ngati kuvala koyambira, kuvala pamwamba, kuthira mbeu kapena feteleza, koma imagwira bwino ntchito ngati feteleza woyambira.

TSP imagwiritsidwa ntchito chimanga ndi mbewu zokolola monga tirigu, chimanga, manyuchi, thonje, zipatso, ndiwo zamasamba ndi zina zotero.
