Sabbin na'urori masu auna firikwensin ƙasa na iya inganta ingantaccen amfanin gona

Auna zafin jiki da matakan nitrogen a cikin ƙasa yana da mahimmanci ga tsarin aikin gona.

labarai-2Ana amfani da takin da ke ɗauke da nitrogen don ƙara yawan abinci, amma hayaƙinsu na iya gurɓata muhalli.Don haɓaka amfani da albarkatu, haɓaka yawan amfanin gona, da rage haɗarin muhalli, ci gaba da sa ido a ainihin lokacin na kadarorin ƙasa, kamar zafin ƙasa da fitar da taki, yana da mahimmanci.Na'urar firikwensin nau'i-nau'i da yawa yana da mahimmanci don aikin noma mai wayo ko daidaitaccen aikin noma don bin diddigin hayakin NOX da zafin ƙasa don mafi kyawun hadi.

James L. Henderson, Jr. Memorial Mataimakin Farfesa na Kimiyyar Injiniya da Makanikai a Jihar Penn Huanyu "Larry" Cheng ya jagoranci haɓaka na'urar firikwensin nau'i-nau'i da yawa wanda ya sami nasarar raba zafin jiki da siginar nitrogen don ba da damar daidaitattun ma'auni na kowane.

Cheng ya ce,“Domin ingantacciyar hadi, akwai buƙatar ci gaba da lura da yanayin ƙasa, musamman amfani da nitrogen da zafin ƙasa.Wannan yana da mahimmanci don kimanta lafiyar amfanin gona, rage gurɓatar muhalli, da haɓaka aikin noma mai ɗorewa da daidaito.”

Nazarin yana nufin yin amfani da adadin da ya dace don mafi kyawun amfanin gona.Noman amfanin gona na iya zama ƙasa da yadda ake iya samu idan an yi amfani da nitrogen da yawa.Idan aka yi amfani da taki fiye da kima, sai a bata shi, tsire-tsire na iya konewa, sannan ana fitar da hayakin nitrogen mai guba a cikin muhalli.Manoma za su iya kaiwa matakin da ya dace na taki don haɓakar shuke-shuke tare da taimakon ingantaccen matakin gano nitrogen.

Mawallafin Li Yang, farfesa a makarantar koyon fasahar kere-kere na jami'ar Hebei ta kasar Sin, ya ce,“Har ila yau, zafin jiki yana tasiri ci gaban shuka, wanda ke shafar tsarin jiki, sinadarai, da tsarin ƙwayoyin cuta a cikin ƙasa.Ci gaba da sa ido yana baiwa manoma damar samar da dabaru da matakan da suka dace lokacin da yanayin zafi ya yi zafi ko sanyi ga amfanin gonakinsu.”

A cewar Cheng, hanyoyin da za su iya samun iskar iskar nitrogen da ma'aunin zafin jiki masu zaman kansu ba a cika samun rahotonsu ba.Dukansu iskar gas da zafin jiki na iya haifar da bambance-bambance a cikin karatun juriya na firikwensin, yana da wahala a rarrabe tsakanin su.

Tawagar Cheng ta ƙirƙiro na'urar firikwensin aiki mai girma wanda zai iya gano asarar nitrogen ba tare da zafin ƙasa ba.An yi firikwensin da vanadium oxide-doped, Laser-induced graphene kumfa, kuma an gano cewa doping karfe hadaddun a cikin graphene inganta gas adsorption da ganewa.

Saboda mai laushi mai laushi yana kare firikwensin kuma yana hana iskar iskar nitrogen, firikwensin yana amsawa kawai ga canje-canjen zafin jiki.Hakanan za'a iya amfani da firikwensin ba tare da rufewa ba kuma a mafi girman zafin jiki.

Wannan yana ba da damar auna daidaitaccen iskar iskar nitrogen ta hanyar ban da tasirin ɗanɗano da zafin ƙasa.Zazzabi da iskar iskar nitrogen za a iya zama gaba ɗaya kuma ba tare da tsangwama ba ta hanyar amfani da na'urori masu auna rufaffiyar da ba a rufe ba.

Mai binciken ya ce za a iya amfani da sauye-sauyen yanayin zafi da iskar iskar iskar nitrogen don ƙirƙira da aiwatar da na'urorin multimodal tare da ɓangarorin hanyoyin gano madaidaicin noma a duk yanayin yanayi.

Cheng ya ce, "Karfin gano ma'aunin iskar nitrogen oxide mai rahusa a lokaci guda da kuma sauye-sauyen yanayin zafi yana ba da damar haɓaka na'urorin lantarki na multimodal a nan gaba tare da ingantattun hanyoyin fahimtar aikin noma, sa ido kan lafiya, da sauran aikace-aikace."

Cibiyoyin kiwon lafiya na kasa, da gidauniyar kimiyya ta kasa, da jihar Penn, da kuma gidauniyar kimiyyar dabi'a ta kasar Sin ne suka dauki nauyin binciken Cheng.
