Theralytic sensor inobatsira varimi kutonga kushandiswa kwefetereza

Smart sensor tekinoroji iyo inobatsira varimi kushandisa fetereza zvakanaka uye kuderedza kukanganisa kwezvakatipoteredza.
Michina iyi, inotsanangurwa mumagazini inonzi Natural Foods, inogona kubatsira varimi kuona nguva yakanaka yekushandisa fetereza pazvirimwa uye huwandu hwefetireza inodiwa, vachifunga nezvemamiriro ekunze uye ivhu. Izvi zvinoderedza kudhura uye kukuvadza kwezvakatipoteredza overfertilization yevhu, iyo inoburitsa greenhouse gasi nitrous oxide uye inosvibisa ivhu nemvura.
Nhasi, fetereza yakawandisa yave kuita kuti chikamu gumi nembiri kubva muzana chevhu raimborimwa risashande, uye kushandiswa kwefetireza yenitrogen kwawedzera ne600% mumakore makumi mashanu apfuura.
Zvakadaro, zvinonetsa kuti varimi vezvirimwa vanyatso gadzirisa kushandisa kwavo fetereza: yakawandisa uye vanoisa panjodzi yekukuvadza nharaunda nekushandisa mari shoma uye vanoisa panjodzi yegoho rakaderera;
Vatsvagiri paiyo nyowani sensor tekinoroji vanoti inogona kubatsira nharaunda nevagadziri.
Iyo sensor, inonzi pepa-based chemically functionalized magetsi gas sensor (chemPEGS), inoyera huwandu hweammonium muvhu, chidimbu chinoshandurwa kuva nitrite uye nitrate nemabhakitiriya evhu. Inoshandisa mhando yehungwaru hwekugadzira inonzi kudzidza muchina, ichiisanganisa nedata remamiriro ekunze, nguva kubva pakushandiswa kwefetereza, kuyerwa kwevhu pH uye conductivity. Inoshandisa ruzivo urwu kufanotaura huwandu hwenitrogen muvhu iye zvino uye huwandu hwenitrogen yemazuva gumi nemaviri ari mberi kufanotaura nguva yakanaka yekushandisa fetereza.
Ongororo iyi inoratidza kuti mushonga mutsva uyu usingadhuri zvikuru ungabatsira sei varimi kuwana pundutso huru kubva mufotereza shoma, zvikuru yezvirimwa zvinodya fetereza segorosi. Iyi tekinoroji inogona panguva imwe chete kuderedza mutengo wevagadziri uye kukuvadza kwezvakatipoteredza kubva kune nitrogen fetiraiza, iyo inonyanya kushandiswa mhando yefetereza.
Mumwe muongorori anotungamirira Dr Max Greer, weDhipatimendi reBioengineering paImperial College London akati: “Dambudziko rekudyara fetereza yakawandisa, kubva mumaonero ezvakatipoteredza uye ezveupfumi, harigoni kupfuudzwa.
“Michina yedu inogona kubatsira kugadzirisa dambudziko iri kuburikidza nekubatsira varimi kuti vanzwisise huwandu hweammonia nenitrate muvhu uye kufanotaura huwandu hweramangwana zvichienderana nemamiriro ekunze.
Fetereza yenitrogen yakawandisa inoburitsa nitrous oxide mumhepo, gasi regreenhouse rine simba rakapetwa ka300 pane kabhoni dhaokisaidhi uye richikonzera dambudziko remamiriro ekunze. Fetereza yakawandisa inogona zvakare kukukurwa nemvura inonaya ichipinda mumikoto yemvura, ichinyima upenyu hwemumvura mweya weokisijeni, zvichiita kuti algae itumbuke uye kuderedza kusiyana kwezvipenyu.
Zvakadaro, kunyatsogadzirisa mazinga efetiraiza kuti aenderane nevhu nezvinodiwa zvechirimwa zvinoramba zvichinetsa. Kuongorora hakuwanzoitiki, uye mitoo yazvino yokuyera nitrogen yevhu inobatanidza kutumira masample evhu kurabhoritari—muitiro wakareba uye unodhura une miuyo inoshandiswa zvishoma panguva yainosvika kuvarimi.
Dr Firat Guder, munyori mukuru uye muongorori mukuru muImperial's Department of Bioengineering, vakati: “Chikafu chedu chizhinji chinobva muvhu – ivhu risingadzokerikezve uye kana tikasarichengetedza tinorashikirwa naro.Zvakare, kusanganiswa nekusvibiswa kweNitrogen kubva mukurima kunopa dambudziko rekuwedzera kwepasi iro tinotarisira kubatsira kugadzirisa kuburikidza nekurima kwegoho, zvichibatsira kuderedza kurima kwegoho. purofiti.”
