Masensa atsopano a m'nthaka amatha kupititsa patsogolo umuna wa mbewu

Feteleza wokhala ndi nayitrogeni amagwiritsidwa ntchito kuonjezera kupanga chakudya, koma utsi wake ukhoza kuipitsa chilengedwe.Kuti muwonjezere kugwiritsa ntchito zinthu, kukweza zokolola zaulimi, ndikuchepetsa kuopsa kwa chilengedwe, kuyang'anira nthawi zonse ndi zenizeni za nthaka, monga kutentha kwa nthaka ndi kutuluka kwa feteleza, ndizofunikira.Sensa yamitundu yambiri ndiyofunikira paulimi wanzeru kapena wolondola kuti utsatire mpweya wa NOX komanso kutentha kwa dothi kuti pakhale feteleza wabwino kwambiri.

James L. Henderson, Jr. Memorial Associate Pulofesa wa Engineering Science ndi Mechanics ku Penn State Huanyu "Larry" Cheng adatsogolera chitukuko cha makina opangira ma parameter ambiri omwe amalekanitsa bwino zizindikiro za kutentha ndi nayitrogeni kuti alole kuyeza kolondola kwa aliyense.

Cheng anati,“Kuti pakhale feteleza bwino, pamafunika kuwunika mosalekeza komanso munthawi yeniyeni momwe nthaka ilili, makamaka kagwiritsidwe ntchito ka nayitrogeni ndi kutentha kwa nthaka.Izi ndizofunikira pakuwunika thanzi la mbewu, kuchepetsa kuwononga chilengedwe, komanso kulimbikitsa ulimi wokhazikika komanso wolondola. "

Kafukufukuyu akufuna kugwiritsa ntchito kuchuluka koyenera pa zokolola zabwino kwambiri.Kukolola kwa mbewu kungakhale kochepa kuposa momwe kungakhalire ngati nitrogen yambiri itagwiritsidwa ntchito.Feteleza akagwiritsidwa ntchito mopitirira muyeso, amawonongeka, zomera zimatha kupsa, ndipo utsi wapoizoni wa nayitrogeni umatulutsidwa m’chilengedwe.Alimi amatha kufika pamlingo woyenera wa feteleza woti zomera zikule mothandizidwa ndi kuzindikira kwabwino kwa nayitrogeni.

Co-author Li Yang, pulofesa ku School of Artificial Intelligence ku Hebei University of Technology ku China, adati,“Kukula kwa zomera kumakhudzidwanso ndi kutentha, komwe kumakhudza momwe nthaka imayendera, mankhwala, ndi tizilombo toyambitsa matenda.Kuwunika mosalekeza kumathandizira alimi kupanga njira ndi njira zothandizira pakatentha kwambiri kapena kuzizira kwambiri kwa mbewu zawo. ”

Malinga ndi Cheng, Njira zowonera zomwe zimatha kupeza mpweya wa nayitrogeni ndi miyeso ya kutentha popanda wina ndi mnzake sizimanenedwa kawirikawiri.Mipweya yonse ndi kutentha zingayambitse kusiyana kwa kuwerenga kwa sensor, zomwe zimapangitsa kuti zikhale zovuta kusiyanitsa pakati pawo.

Gulu la Cheng linapanga kachipangizo kochita bwino kwambiri kamene kamatha kuzindikira kutayika kwa nayitrogeni popanda kutentha kwa nthaka.Sensayi imapangidwa ndi vanadium oxide-doped, laser-induced graphene foam, ndipo zapezeka kuti doping metal complexes mu graphene imapangitsa kuti gasi adsorption ndi kuzindikira kuzindikira.

Chifukwa nembanemba yofewa imateteza sensa ndikulepheretsa mpweya wa nayitrogeni kulowa, sensa imangochita kusintha kwa kutentha.Sensa imatha kugwiritsidwanso ntchito popanda encapsulation komanso kutentha kwambiri.

Izi zimathandiza kuyeza bwino kwa mpweya wa nayitrogeni posaphatikizanso mphamvu ya chinyezi ndi kutentha kwa nthaka.Kutentha ndi mpweya wa nayitrogeni ukhoza kulumikizidwa popanda kusokoneza pogwiritsa ntchito masensa otsekedwa komanso osasunthika.

Wofufuzayo adati kuchepetsa kusintha kwa kutentha ndi mpweya wa nayitrogeni zitha kugwiritsidwa ntchito kupanga ndikugwiritsa ntchito zida zama multimodal zokhala ndi njira zodziwikiratu zaulimi wolondola nyengo zonse.

Cheng adati, "Kutha kuzindikira nthawi imodzi kutsika kwa nitrogen oxide ndi kusintha kwakung'ono kwa kutentha kumapereka njira yopangira zida zamagetsi zamtsogolo zokhala ndi njira zodziwikiratu zaulimi wolondola, kuyang'anira thanzi, ndi ntchito zina."

Kafukufuku wa Cheng adathandizidwa ndi National Institutes of Health, National Science Foundation, Penn State, ndi Chinese National Natural Science Foundation.
