Ammonium sulphate fetereza - pantry asafe ndi sulfure

Ammonium sulphate ndi kupanga asafe-sulfure fetereza, muli 24% sulfure ndi 21% asafe. Kunja izo akufanana woyera crystalline mchere umene uli bwino sungunuka m'madzi ndi mankhwala ndale. Ammonium sulphate ali hygroscopicity otsika ndi kusunga yaitali izo sizitero mkate, pamene kusunga flowability. Ndipo mtengo wa zinthu uli m'bukuli, zimavuta Musaone. The asafe chomwecho amakhudza kwambiri pa moyo wa mbewu. Iye ankaona mtsogoleri pakati pa feteleza. Ndi sulfure kuti kufunika mu mbewu zakudya angaperekedwe ku malo lachitatu kuyambira yachiwiri phosphorous.

Ammonium sulphate - fetereza, amene ntchito lipindulitsa pa mitundu yonse ya mbewu. Iye alibe vuto kupanga sungunuka m'madzi, kenako bwino chosakanikirana ndi zomera. Komanso, ndi kulalikira, ndipo ngakhale pa chinyezi mkulu si kutsukidwa kwa nthaka. Koma mphamvu ya feteleza ili si chozama kupitirira wa urea ndi nitrate ammonium. Koma ngati ife tione ena mwa thupi-mankhwala ake katundu (flammability, kuphulika, neslezhivaemost) ndipo mtengo wa sulphate ndi ammonium ndi zambiri yabwino kwambiri kwa awo "Otsutsa". Komanso ndi yofunika zikuluzikulu za feteleza ili ndi sulfure; amagwira ntchito yofunika kwambiri pa moyo wa mbewu. Ndi mbali ya mapuloteni ndi kwa amino zofunika zidulo monga methionine ndi cystine. izo ndi kupezeka mavitamini ndi mafuta.

Pa nkhani imeneyi, ammonium sulphate kuli ndi ubwino pa njira redox kunachitika zomera, komanso kutsegula kwa michere ndi mapuloteni kagayidwe, likuyamba mfundo kaphatikizidwe chimene oxidized monga mawonekedwe a sulfa. Ndipo ngati akusowa, ndiye mapuloteni kaphatikizidwe anachedwa, ndi zomera akuyamba otchedwa sulfure njala, amene makhalidwe awo amatikumbutsa asafe ndi njala. Pa mbewu omwewo zizikhala chitukuko, iwo elongated zimayambira ndi masamba yafupika. Komabe, yotsirizira siumafa, koma kutenga mtundu wotumbululuka. Ndipo Kafukufuku wasonyeza kuti akusowa sulfure amachititsa zipolowe za kagayidwe asafe. Ndipo zikhoza kupewedwa ngati sulphate pokha ammonium. Feteleza chomwe chingathandize kubwezeretsa kupanda sulfure.

Alimi kudziwa kuti ntchito kwambiri feteleza asafe kungabweretse mavuto zachilengedwe, makamaka ngati simuli zakudya kusamala iwo. Izi zikhoza kukhala kuipitsa pamwamba ndi pansi, zanitrachivanie mankhwala. Komanso urea nitrate feteleza ndipo pali awiri a asafe (30%), zimene zimabweretsa ku leaching ndi denitrification. A sulphate ammonium wotaya osapitirira 3% ya batire. Tikumbukenso kuti pali asafe mu mawonekedwe ambiri Kufikika zomera, ndi mapangidwe mbewu kumafunikanso lonse kukula nyengo.

More sulphate ammonium ntchito yotaya udzu. Pa nthawi yomweyo likukhalira ku fetereza ndi. Ndiko kuti, analengedwa mu nthaka ndi udzu pa makilogalamu 10 pa tani udzu. Choncho zimalimbikitsa makhalidwe oipa inapita wa mapadi. Pa nkhani imeneyi, nthawi yomweyo ife anathana ndi mavuto angapo - nthaka kulandira fetereza zina, udzu ndi zobwezerezedwanso kuteteza chilengedwe. Ngati mbewu zokolola za 20-30 quintals pa mahekitala, ndi ammonium sulphate pamodzi ndi udzu otsalira pambuyo pawo ndi kubwerera kwa nthaka kuti makilogalamu 40 a asafe, potaziyamu 18-24 makilogalamu, makilogalamu 80 a phosphorous ndi 35-45 makilogalamu sulfure, amene bwino kwambiri kuchuluka kwa mapuloteni okhutira mu mankhwala.
