Feteleza potaziyamu sulphate

Sulphate ya potaziyamu ndi fetereza yowonjezera, yomwe imaphatikizapo peresenti 50 peresenti, 18% sulfure, 3% magnesiamu ndi 0,4% calcium. Maonekedwewo ndi oyera, nthawi zina ndi malaya a grayish, crystalline powder. Sulphate ya potaziyamu ilibe chlorine ndipo zimayambira bwino zimakhala zosungunuka bwino m'madzi ndipo sizitenga keke pamene zasungidwa kwa nthawi yaitali.

Kodi mungagwiritse ntchito bwanji potaziyamu sulfate?

Kugwiritsa ntchito potassium sulphate ndi nayitrogeni ndi phosphate feteleza kumapangitsa kuti phindu likhale lopindulitsa, koma kugwiritsa ntchito panthawi imodzi ndi urea, choko sikovomerezeka.

Amagwiritsidwa ntchito kwambiri mu ulimi phulusa sulphate monga feteleza analandira, chifukwa:

• kuonjezera mavitamini ndi shuga mu chipatso;
• zimakhudza kwambiri mtundu wa mbewu ndi mtundu wake;
• zimathandizira kuti nyengo yozizira ikhale yopambana ya mitengo ndi mabulosi ndi zitsamba;
• Angagwiritsidwe ntchito pa dothi losiyanasiyana (sod-podzolic, peat, chifuwa, sulfuric, acidic).

Potaziyamu sulphate ikhoza kugwiritsidwa ntchito poyera ndi kutsekedwa (wowonjezera kutentha) dothi, komanso zomera za m'nyumba.

Iyo ikalowa mu nthaka, potaziyamu, yomwe ili gawo la fetereza fetereza, imadutsa m'nthaka zovuta, zomwe zimagwiritsidwa ntchito ndi zomera. Pa dothi ndi dothi loamy, potaziyamu sulphate imayikidwa ndipo pafupifupi sichimasunthira kumtunda wa nthaka, ndipo pamtunda wochepa mchenga - potaziyamu ukuyenda kwambiri. Choncho, kuti apereke zomera ndi potaziyamu, amayesera kuziyika muzomwe zimayambira pamene mizu yambiri imapezeka. Mu dothi lolemera, feteleza potaziyamu iyenera kugwiritsidwa ntchito m'dzinja kwa kuya kwakukulu, komanso mu dothi la mchenga mumtunda komanso popanda kukulitsa. Mwachitsanzo, mutabzala mtengo wa zipatso pa dothi la clayey ndi loamy pansi pa dzenje, muyenera kuwonjezera potaziyamu sulphate pamodzi ndi phosphate feteleza, popeza kuyambira kwa feteleza feteleza mu nthaka yosanjikiza sichidzapereka mtengo wa chipatso chofunikira cha zakudya za potassium.

Kodi mungagwiritse ntchito bwanji potassium sulphate?

Sipate ya potaziyamu ingapangidwe m'njira ziwiri:

• kumapeto kwa nyengo kapena m'dzinja ndi kukumba kwa nthaka;
• monga kuvala pamwamba pa nthawi ya kukula.

Kugwiritsa ntchito potaziyamu sulphate ndi kotheka kwa magulu otsatirawa:

• kumvetsetsa klorini ( mphesa , mbatata, fulakesi, fodya, zipatso);
• banja cruciferous (rutabaga, kabichi, mpiru, mpiru, radish);
• kudya kwambiri sulfure (nyemba);
• Mitengo ya mabulosi ndi zitsamba (gooseberries, yamatcheri, plums , mapeyala, raspberries ndi mitengo ya apulo).

Mlingo wa kugwiritsa ntchito fetereza wotero umadalira njira yogwiritsira ntchito ndi mtundu wa mbewu:

• pa waukulu ntchito ya strawberries, tomato, nkhaka ndi maluwa - 15-20 g / m2, chifukwa kabichi, beets, kaloti, mbatata - 25-30 g / m2;
• mukamabzala mitengo ya zipatso - 150-200 g pa kubwera dzenje;
• Pamwamba pa kuvala masamba a masamba ndi strawberries - 10-15g / m2, mabulosi a mabulosi - 15-20g / m2 kapena kupanga grooves 6-8cm chakuya pafupi ndi zomera pafupi ndi zomera, amapanga 50-100g / m2 pamenepo.

Ngati chovala chokongoletsera chikuchitika kudzera mu njira yothirira, ayenera kukonzekera njira yothetsera potassium sulphate ndi ndondomeko ya 0.05-0.1%, chifukwa cha foliar pamwamba kupopera mankhwala opopera mankhwala. Njira ya 1-3%, komanso ulimi wothirira, 10-40 malita a madzi amatsitsimutsidwa mu malita 10 a madzi, ndipo zomera 10-20 zimathiriridwa ndi njirayi.

Potassium sulphate sichikhala ndi poizoni ndi zowononga, koma ngati zimakhala pakhungu, m'maso kapena mkati, zimatha kukhumudwitsa mazira, poizoni milandu ndizosawerengeka kwambiri, ndipo zimakhala zochepa kwambiri.

Mu horticulture, potaziyamu sulphate imagwiritsidwa ntchito monga fetereza nthawi zambiri, chifukwa Alibe chlorine, ndipo potaziyamu imachotsedwa bwino, yomwe ndi yofunikira kupeza zinthu zabwino kwambiri, kuchepetsa zokolola za mbeu panthawi yosungirako, komanso kukwera kwa matenda ndi tizirombo.
