Yakafanira fetiraiza superphosphate miti achapa uve akapfuma kukohwa

Kudzorera zvicherwa Kuronga topsoil pashure kukura zvirimwa inoverengeka nzira. Chinhu aitungamirira fetiraiza. Izvi zvinoitwa anyanye nechokwadi mbesa huru zvinovaka muviri matatu: senitrogen, potassium uye phosphorus. Panyaya iyi, nyanzvi mupfudze superphosphate.

Kuita izvozvo kunobatsira kuti midzi miti, kuchengetedza kana nokudzosa kukura kwavo utano uye kukura, tava kuderera ari oxidation uye runogonesa kuti rokuzvivandudza rakaita kuti irambe pezvakaitwa muvhu uye ivhu. Fertile rukoko vafumiswa aine zvakakwana yakawanda senitrogen uye phosphorous, potassium, calcium, magnesium nesarufa. A zvakananga mugumisiro izvi kuwedzera goho uye kuvandudza unhu hwavo.

Superphosphate fetiraiza zvinobudirira dzavo dzakaoma migumisiro. chikuru chinoumba wayo phosphorus, senitrogen zvinofanira kutevedzerwa. Nokuti neutralizing kunyanya acidity ivhu remhosva karusiyamu. Magnesium - chinhu chinokosha mu mbatatisi kurimwa. Sarufa kunobatsira kukura bhinzi, mbeu uye oilseeds.

Mune nzira pakuburitswa phosphoric asidhi uye superphosphates kugutsikana kunogona kuva nyore kana kaviri (dzimwe nguva katatu). Ivo zvinowanikwa upfu uye granular chimiro.

Simple superphosphate rine kubva 14 kusvika 19.5% kubva phosphorus; yake miviri, ukuwo, kaviri. Izvi akatorwa paunoronga kuberekesa ivhu uye zvinomera. Pakuitisa chitubu kana matsutso kuchera mibhedha yadzoswa 100-200 g superphosphate pa 1 sq.m. fetiraiza iyi yaishandiswa mvura dzichifura: 12-25? g yakanyauka muna 10 litres mvura akandipa kwemazuva maviri kana matatu.

Kushaikwa superphosphate - chinokosha zviri karusiyamu sulfate (gypsum) hunosvika mu mugove wayo 40%. Kutaura zvazviri, kuti Chikwata, kurima gadheni uye varimi, iye - kutakura kutsigisa igwa. Kunyange superphosphate fetiraiza dzimwe nguva kunogona kubatsira nemhaka karusiyamu sulfate Somuenzaniso, panyaya nevhu varombo nesarufa, uyewo kana pane miti kuti uchapedza yakawanda nesarufa. Zvisinei, ruzhinji gypsum chirimwa anoramba kushanda maturo chicherwa.

Granular superphosphate ane akasiyana paanopfuura fetiraiza iri asunungurwa muchimiro chiduku hacho. Chokwadi chokuti weupfu superphosphate muvhu (kunyanya kana zviri acidic) ive mamiriro umo zvinovaka muviri yayo yose kuwanikwa miriwo. Uye zvakawanda kwazvo riri hwakakanyiwa ivhu, zvikuru maturo rova. Superphosphate granules ose 1-4 mm vane drawback ichi, asi nokuti zvine phosphoric asidhi nani zvikuru uye yakareba kunyura miti. Fetiraiza izvozvo zvakanaka mumuviri ehupfumi: hazvina keke uye tsime vakapararira pamusoro nzvimbo.

Superphosphate fetiraiza zvinobudirira kushandiswa kwete chete zvakananga kuti zvinomera, asi somunhu chirungiso kune matsva shiri nhoko. Izvi zvinoitwa kuti vasunge mariri ammoniacal senitrogen kupinda involatile siyana uye kudzivirira kurasikirwa kwayo panguva okuchengetera. Mumwe makirogiramu pamusoro superphosphate, akawedzera kuti mufudze, anoramba vanenge 400-500 magiramu ose senitrogen.
