Yoyenera fetereza superphosphate zomera adzapereka inu kukolola olemera

Kubwezeretsa mchere zikuchokera topsoil pambuyo kukula mbewu ankagwiritsa ntchito njira. Ndi fetereza kutsogolera. Izi zachitika makamaka kuonetsetsa zomera zakudya zazikulu zitatu: asafe, potaziyamu ndi phosphorous. Pa nkhani imeneyi, kwambiri zothandiza fetereza superphosphate.

Kupanga bwino mizu ya zomera, kukhalabe kapena abwezeretse kukula wathanzi ndi chitukuko, liwiro la makutidwe ndi okosijeni ndipo umatithandiza njira regenerative m'nthaka ndi nthaka. Chonde wosanjikiza apindula ndi okwanira kuchuluka kwa asafe ndi phosphorous, potaziyamu, calcium, magnesium ndi sulfure. A chotsatira chenicheni cha ichi ndi kuonjezera zokolola ndi kusintha khalidwe lawo.

Superphosphate feteleza bwino zotsatira zawo zovuta. chigawo Aika ndi phosphorous, asafe ayenera kutsatiridwa. Pakuti neutralizing kwambiri acidity wa nthaka likukwaniritsa calcium. Mankhwala enaake a - ndi chinthu chofunika kwambiri kulima mbatata. Sulfa amathandiza kukula nyemba, mbewu ndi oilseeds.

Mu njira yopanga asidi phosphoric ndi superphosphates zili akhoza kukhala wophweka kapena awiri (nthawizina patatu). Zilipo ufa ndi mawonekedwe granular.

Zambiri superphosphate lili ku 14 19,5% wa phosphorous; ake awiri, motero, kawiri. Izi n'komwe pamene feteleza nthaka ndi zomera. Pochititsa kasupe kapena yophukira kukumba mabedi ndi anabweretsa 100-200 ga superphosphate pa 1 sq.m. feteleza Izi ntchito kudya madzi: 12-25 ga uli kusungunuka malita 10 a madzi ndi kuikidwa kwa masiku awiri kapena atatu.

Kupanda superphosphate - zili zofunika kwambiri za kashiamu sulphate (gypsum) imene imafika ku cholowa 40%. Ndipotu, kwa wamaluwa, wamaluwa ndi alimi, iye - kunyamula ballast. Ngakhale superphosphate fetereza zikhoza kukhala zothandiza chifukwa cha sulphate calcium, mwachitsanzo, mu nkhani ya dothi osauka sulfure, komanso ngati pali zomera kulakalaka yambiri sulfure. Komabe, ambiri a mbewu gypsum amakhalabe pafupifupi opanda ntchito mchere.

Granular superphosphate ali ndi mwayi osiyana pa fetereza ndi amachoka mu mawonekedwe a kagawo kakang'ono. Popeza kuti ufa superphosphate m'nthaka (makamaka ngati Acidic) mu boma limene zakudya zonse zilipo kwa zomera. Ndi bwino kwambiri ndi wothira nthaka, m'pamenenso achabechabe kumakhaladi. Superphosphate granules wa 1-4 mamilimita ndi drawback izi, koma chifukwa zili phosphoric asidi bwino kwambiri ndi wautali chosakanikirana ndi zomera. Fetereza ngati ali katundu labwino: izo sizitero mkate ndi bwino anamwazikana malo.

Superphosphate feteleza bwino ntchito osati mwachindunji kwa zomera, komanso ngati zowonjezera ku zitosi atsopano mbalame. Izi zachitika kuti kumumanga m'menemo ammoniacal asafe mu njira involatile ndi kupewa imfa yake pa yosungirako. makilogalamu mmodzi wa superphosphate, anawonjezera kuti manyowa, akuzisunga za 400-500 magalamu a asafe.
