Ukushintsha Kwesimo Sezulu, Ithuba Elilethwa Izibani Ze-LED Zezitshalo Ekutshaleni Ngasendlini

Umthelela wokuguquka kwesimo sezulu endaweni yokukhula kwezitshalo. Ukushintsha kwesimo sezulu kuye kwabangela ukuba izinga lokushisa likhuphuke, okuye kwaholela ekuthuthukisweni kokusebenza kwamagciwane enhlabathini, okusheshisa ukulahleka kwezinto eziphilayo zenhlabathi kanye ne-nitrogen, okubangela ukuwohloka kwenhlabathi, ukuguguleka nosawoti. Ngesikhathi esifanayo, izinguquko ezimweni zokushisa zesifunda zithinta inqubo yokujikeleza kwamanzi emhlabeni wonke, ukushintsha iphethini yemvula yesifunda nokusatshalaliswa kwemvula, futhi kwandise ukuvela kwezehlakalo ezimbi kakhulu njengezikhukhula nesomiso. Eminyakeni yamuva, izehlakalo zezulu ezimbi kakhulu ezibangelwa ukushintsha kwesimo sezulu ziye zaqina kakhulu. Ngokuvamile, izikhukhula eziseningizimu kanye nesomiso enyakatho, futhi indawo yenhlekelele iyanda, okuholela ekuvinjweni okukhulu kwezitshalo esifundeni, ngisho nokuvuna. Ngaphezu kwalokho, izinhlekelele zesimo sezulu ezinjengokushisa okuphansi kanye nokulimala okubandayo kanye nokulimala kokushisa okubangelwa izinguquko ezimbi kakhulu esimweni sezulu somhlaba nazo zenzeke. Ngokuvamile, umkhuba wokulimala kwesithwathwa kanye nokulimala kwesithwathwa eNyakatho-mpumalanga naseNyakatho yeChina uyakhula. Ukuthambekela, ngisho nalabo abathintwe yinhlekelele kwezinye izindawo, kuholele ekwehleni kokukhiqizwa kwerayisi ngamaphesenti ayi-10 kuye kwayi-18, okuthinte kakhulu ukuphepha kokukhiqizwa kokudla endaweni eyinhloko yokukhiqiza ukudla ezweni lami. Umthelela wokuguquka kwesimo sezulu ohlelweni lokutshala izitshalo. Ukuguquka kwesimo sezulu emhlabeni jikelele kusheshise inqubo yokuzalwa kwezilimo zokuqala kwezinye izindawo ezithintekile, kwanciphisa isikhathi sokuzalwa, futhi kwenza buthakathaka amandla okumelana nokuguquguquka kwesimo sezulu. Ikakhulukazi esifundeni sase-East China sebhali lezwe lami, ukolweni nezitshalo ze-rapeseed. Izitshalo eziningi ezitshalwa kule ndawo ziyizinhlobo ezisakhula. Ngokufudumala kwesimo sezulu sasebusika, izitshalo nazo zifinyezwa ngesikhathi sasebusika. Ngokushisa kwesimo sezulu, yethulwa kusenesikhathi, okwenza buthaka ikhono lesitshalo lokumelana nokubanda, okwaholela ekutheni isitshalo esasingase sihlaselwe umonakalo owenziwe yiqhwa, okubangele umonakalo omkhulu ekukhiqizeni izitshalo. Lokhu kubeka phambili izinselelo ezintsha zokulungiswa kohlelo lokutshala lwezwe lami. Ngenxa yokuthi umanyolo we-nitrogen ungakwandisa kakhulu ukukhiqizwa kokudla, umanyolo we-nitrogen wembulunga yonke uye wakhula ngokushesha, futhi inhlabathi ene-nitrogen iye yanda. UPhil noRobertson baseMi Ogin State University bakholelwa ukuthi ukukhishwa kwesisi esibamba ukushisa okubangelwa ukukhiqizwa kwezolimo kulinganiselwa ku-8 % -14 % wengqikithi yomhlaba wonke. Ucwaningo luye lwabonisa ukuthi abalimi banganciphisa ngokuphumelelayo ukusetshenziswa komanyolo wamakhemikhali ngokufaka umanyolo oqondile, ngaleyo ndlela banciphise ukukhishwa. I-CO2 high concentration inhibitory inhibitory Crop nitrite ibe inqubo yokuguqulela ibe amaprotheni. Ukuhlanganiswa kwe-nitrogen, okwaziwa nangokuthi inqubo yokuhlanganisa i-nitrogen, kudlala indima ebalulekile ekukhuleni kwezitshalo nasekukhiqizeni. Ezitshalweni zokusanhlamvu, i-nitrogen ibaluleke kakhulu, ngoba ukusetshenziswa kwe-nitrogen ukukhiqiza amaprotheni abalulekile ekudleni kwabantu ngoba izitshalo zisebenzisa i-nitrogen. Ngokusho kweBritish "Guardian", ososayensi benza izivivinyo zensimu zikakolweni, irayisi, ummbila nobhontshisi wesoya. Ukuhlolwa kwafakazela ukuthi izinga le-CO2 le-CO2 lehlise kakhulu imisoco eyisisekelo yalezi zitshalo njenge-iron ne-zinc. Ngesikhathi esifanayo, okuqukethwe kwamaprotheni kulezi zitshalo kuyancipha. Ngokocwaningo, ukukhula kukakolweni kumazinga aphezulu e-CO2 kwehla ngo-9 % uma kuqhathaniswa nokuqukethwe kwe-zinc evamile evundlile, insimbi encishisiwe ngo-5%, futhi okuqukethwe kwamaprotheni kwehla ngo-6%; Ngokufanayo, okuqukethwe kwe-zinc zerayisi elikhula kumazinga aphezulu e-CO2 kwehlile. 3%, insimbi yehle ngo-5%, amaprotheni ehle ngo-8%; okuqukethwe kwe-zinc nensimbi kummbila nobhontshisi wesoya kwehle ngokufanayo, kodwa okuqukethwe kwamaprotheni akuzange kushintshe kakhulu. Ngokuzenzakalelayo, umagazini othi "Natural Climate Change" ushicilelwe "I-Tomlet of Nitrates of Growth Growth in the Fields" icindezelwa yi-CO2 ephakeme ". Ucwaningo lwaleli phepha lufakazela okokuqala ukuthi ukugxila kwe-CO2 ephakeme lapho ukugxila komkhathi kuye kwacindezela inqubo yokuguqula i-nitrate nitrate ibe amaprotheni ibe amaprotheni. Lokhu kusho futhi ukuthi ukuguquguquka kwesimo sezulu kuyaqina, okuzoholela eqophelweni elibi lokudla okunomsoco kwezitshalo zokudla. I-nitrogen ephilayo equkethe izinhlanganisela enhlabathini ikakhulukazi etholakala ekuboleni kwezilwane, izitshalo kanye nemizimba yamagciwane, kodwa iningi lalezi zinhlanganisela eziqukethe i-nitrogen azincibiliki emanzini futhi ngokuvamile azisetshenziswa izitshalo. Izitshalo zingamunca ama-amino acid kuphela phakathi kwazo. , I-nitride ephilayo engancibiliki njenge-amide ne-urea. Ngakho-ke, i-inorganic nitrogen alcohols ikakhulukazi esekelwe ku-ammonium ne-nitrate, ibalwa ku-1% -2 % wokuqukethwe kwe-nitrogen emhlabathini. Ngemva kokuba isitshalo simunca usawoti we-ammonium emhlabathini, singawusebenzisa ngokuqondile ukuze sihlanganise ama-nitride ephilayo njengama-amino acid; uma i-nitrate imuncwa, kufanele ibuyiselwe ukuze isetshenziswe. Ngamafuphi, lesi sitshalo simunca i-ammonium emhlabathini, noma ifakwe ngokushesha ku-amino acid ngemva kokuba i-ammonium incishisiwe ngokuncishiswa kwe-nitrate. Ukufakwa kwe-ammonia kwenziwa ezimpandeni, isimila sezimpande kanye neqabunga. Emashumini ambalwa eminyaka alandelayo, inani lamaprotheni lingancipha cishe ngo-3%. Njengamanje, ubuchwepheshe bokutshala obunezinhlangothi ezintathu bokuthuthukiswa okusebenzayo kwamazwe aseYurophu naseMelika kanye namanye aseNingizimu-mpumalanga ye-Asia ayidli izinsiza zomhlaba. Indawo evalekile yokusebenzisa umhlabathi inciphisa izinga lomonakalo enhlabathini. Ukusetshenziswa okukhulu kokukhanya okungeziwe kwezitshalo nakho kuxazulula ukuntuleka kokukhanya endaweni yokutshala enezinhlangothi ezintathu. Ngesikhathi esifanayo, i-spectrum yokukhanya kwesithasiselo sesitshalo ingenziwa ngezifiso ngokusho kwezitshalo ezahlukene. Izinyathelo zesimanje zokwenza umfanekiso wokukhiqiza ocolisisiwe. I-Zhuhai igxile ekukhiqizeni ubuhlalu be-patch be-LED obuhlukahlukene. Muva nje, isidingo sezitshalo zobuhlalu besibani se-LED sikhuphuke. Uma udinga uku-oda ubuhlalu besibani sezitshalo ze-LED, ungathintana nesevisi yamakhasimende ukuze uthole i-oda.
