N'chiyani chimachititsa ntchito superphosphate ndi kuti ndi feteleza

Kamodzi, mu chaka 1669, ndi alchemist H.Brandt anapanga pochita izi: mkodzo izo chamunthuyo kuti dryness, precipitate chifukwa anali wothira mchenga ndi makala, kenako osakaniza anali usavutike mu retort womata. Chifukwa cha adalandira mankhwala amene ali ndi katundu zamatsenga za kuwala mu mdima. Kotero ine ndinali woyamba analandira phosphorous. Kuyambira pamenepo, panatenga zaka oposa mazana atatu tsopano, izi amafotokozera mankhwala chimagwiritsidwa ntchito zosiyanasiyana za malonda komanso ulimi. Tiyeni tikambirane zimene angapereke kwa chilimwe awo ntchito kanyumba wa superphosphate ndi mitundu yosiyanasiyana ya izo. Tikukhulupirira m'nkhani ino chidzakhala nkhani kwambiri kwa anthu onse amene zikugwira kulima mbewu m'munda wanu.

Fetereza ndi manambala oyambirira "wapamwamba"

Kutchuka kwa mankhwala chikugwirizana ndi chakuti choncho, choyamba, sanali poizoni, kugonjetsedwa ndi moto ndi kuphulika, ndipo kachiwiri ndi oyenera iliyonse mtundu wa dothi. Kugwiritsa superphosphate umabala mkulu zokolola kwambiri chimanga, Beet, mbatata, fulakesi, masamba, dzinthu ndi mbewu zina. Komanso, akatswiri amalangiza ubwino kuphatikiza kugwiritsa ntchito mankhwala mu zikuchokera kudya zazikulu ndi pang'ono mu zitsime za mizere kapena mwachindunji pamaso kubzalako. Mwina kale zinakhalako nthawi imeneyi funso m'mene mukufunira kuti apange feteleza ili. Onani kuti ntchito superphosphate zimadalira mlingo wa chonde nthaka, ndi ntchito zina organic ku mbewu kukula. Komanso, ayenera kuganizira mtundu wa feteleza ntchito. Mwachitsanzo, kwa mlingo pafupifupi masamba ali 40-60 (pamene pamaso pa losavuta) kapena magalamu 20-30 pa 1 mita ² (ngati mukufuna kugwiritsa ntchito iwiri superphosphate). Ntchito feteleza analimbikitsa m'madera zokolola zimadalira zili sulfure nthaka, umene uli wofunika pamene kukula oleaginous, dzinthu ndi nyemba. Superphosphate kupanga bwino mizere - mu nkhani iyi, mlingo magwiritsidwe wa phosphorous ndi kangapo apamwamba poyerekeza ndi mosintha pamaso yolima. Pa yemweyo nkhanza nthawi deta ya fetereza ndi Sikuti. Makamaka ngati ife kuganizira kuti mu zaka 2-3 cha phosphorous kuloŵerera efficiencies superphosphate ndi pafupifupi 40%.

The zikuchokera ndi mitundu

Kuwonjezera chigawo waukulu, fetereza alipo ulinso ndi nitrogen, sulfure, magnesium ndi calcium. Malinga ndi kuchuluka assimilable ndi / × zikhalidwe phosphorous, superphosphate akhoza kukhala wophweka, pawiri ndi ogwira mtima. Last pa kukonza ali ndi udindo wapakatikati pakati pa awiri. Pakali pano, feteleza izi zikhoza kugulidwa mu ufa kapena mu mawonekedwe granular. Mbali yoyamba, ntchito superphosphate ogula ndalama zayamba mtengo. Chifukwa cha kusanganikirana ake zosavuta mtundu uwu wa feteleza bwino ntchito yokonza composts. Komano, ufa lokonzekera, nthawi zina zimabweretsa zochepa zabwino kuposa granulated superphosphate. Ntchito yotsirizira kupewa caking, kukhala wabwino ankakhala moyo wotayirira, ndi phosphorous ili ndi zambiri (mpaka 22%).
