Ngophuhliso olukhawulezileyo lwezolimo olukrelekrele, izinzwa zomhlaba, njengezixhobo eziphambili zezolimo ezichanekileyo, ukuchaneka kwedatha yazo kuchaphazela ngokuthe ngqo izigqibo zemveliso yezolimo. Uphando lwamva nje lubonisa ukuba iteknoloji yokulinganisa kunye nolawulo oluchanekileyo ziye zaba zizinto eziphambili ezichaphazela ukuthembeka kwedatha yezinzwa zomhlaba, kwaye le ngxaki ifumana ingqwalasela enkulu kwishishini.
Itekhnoloji yokulinganisa: Umgca wokuqala wokukhusela ukuchaneka kwedatha
Ukulinganiswa kweenzwa zomhlaba linyathelo elibalulekileyo ukuqinisekisa ukuchaneka kwedatha. Izifundo zibonisa ukuba impazamo yokubeka esweni idatha yeenzwa ezingalinganiswanga inokuba phezulu ukuya kuthi ga kwi-30%, ngelixa emva kokulinganiswa kobuchwephesha, impazamo ingalawulwa ngaphakathi kwe-5%. Okwangoku, iindlela eziphambili zokulinganisa ziquka ukulinganiswa kwelebhu kunye nokulinganiswa kwindawo.
“Ukulinganiswa kwezivamvo asikokwenziwa kube kanye,” utshilo ingcali evela kwi-Chinese Academy of Agricultural Sciences. “Ukulinganiswa rhoqo kuyadingeka ngokusekelwe kwiintlobo ezahlukeneyo zomhlaba, amanqanaba okufuma kunye neemeko zobushushu ukuqinisekisa ukuchaneka kwedatha.”
Izinto ezisingqongileyo: Izinto ezinefuthe ezingenakubethwa ngoyaba
Iimpawu zomhlaba zinempembelelo enkulu ekuchanekeni kwesensa. Umxholo wetyuwa emhlabeni uya kuchaphazela ngokuthe ngqo ukulinganiswa kombane, ngelixa utshintsho kubushushu bomhlaba luya kuchaphazela ukufundwa kweesensa zomswakama. Ukongeza, ubuncinci kunye nexabiso le-pH yomhlaba kunokuphazamisana neziphumo zokujonga.
Uphando lufumanise ukuba xa ubushushu bomhlaba buphakathi kwe-5 ukuya kwi-35℃, ukuchaneka kwesensa yokufuma yeyona nto iphezulu. Ukuba idlula olu luhlu, kufuneka umlinganiselo wokulinganisela ubushushu. Le yiyo nesizathu sokuba iisensa zomhlaba eziphezulu zonke zixhotyiswe ngeesensa zobushushu ezakhelwe ngaphakathi.
Iiparameter zobugcisa: Isitshixo sokwahlula amanqanaba okuchaneka
Iisensa zamanqanaba ahlukeneyo okuchaneka zibonisa umahluko omkhulu kwidatha yokubeka esweni. Iisensa zamanqanaba elebhu zinokufikelela ekuchanekeni komlinganiselo we-±2%, ngelixa ukuchaneka kweesensa zamanqanaba ezolimo kudla ngokuba malunga ne-±5%. Lo mahluko ekuchanekeni uchaphazela ngokuthe ngqo umgangatho kunye nokuthembeka kokuqokelelwa kwedatha.
“Xa ukhetha izinzwa, umntu akufuneki ajonge ixabiso kuphela,” watsho umntu ophethe iprojekthi ye-HONDE smart Agriculture. “Inqanaba elifanelekileyo lokuchaneka kufuneka likhethwe ngokusekelwe kwiimeko zokwenyani zesicelo.” Umzekelo, iiprojekthi zophando lwesayensi zifuna izinzwa ezichaneke kakhulu, ngelixa ukutyala emasimini, izinzwa zezinga lezolimo zanele.
Ukufakwa kunye nokugcinwa: Izinto ezibalulekileyo ezichaphazela uzinzo lwexesha elide
Indlela echanekileyo yokufaka kunye nokugcinwa rhoqo kuchaphazela ukuchaneka kwedatha yesenzi. Xa uyifaka, qaphela ukuqina koqhagamshelwano phakathi kwesenzi nomhlaba ukuze uphephe ukudala izikhewu ezinokuchaphazela iziphumo zokulinganisa. Ukongeza, ukucoca rhoqo umphezulu wesenzi ukuze kuthintelwe ukukristala kwetyuwa kunye nokunamathela komhlaba nako kukwayindlela ebalulekileyo yokugcina ukuchaneka.
“Sicebisa ukuba kulinganiswe kwindawo nganye rhoqo ngekota,” batsho iingcali zobugcisa. “Ingakumbi emva kokufaka izichumisi okanye izibulali-zinambuzane, kubaluleke ngakumbi ukujonga ukuchaneka kwezinzwa.”
Isisombululo: Indlela esebenzayo yokuphucula ukuchaneka kwedatha
Ukuphucula ukuchaneka kwedatha, eli shishini lizise izisombululo ezahlukeneyo. Oku kuquka ukwamkelwa kwetekhnoloji yokudibanisa iiparameter ezininzi ngaxeshanye ukulinganisa iiparameter ezininzi ezifana nobushushu bomhlaba, ukufuma, kunye nokuqhuba kombane ngaxeshanye, kunye nokuzilungisa macala omabini ngee-algorithms. Phuhlisa i-algorithm yokulinganisa eguquguqukayo ukuze ulungise ngokuzenzekelayo iiparameter ngokweenguqu zendalo; Kwaye usete inkqubo yokulinganisa ekude ukuze ufezekise ukulinganiswa kwi-intanethi ngaphandle kokuphazamiseka kokujonga.
Ezi nguqu zobuchwepheshe ziphucule kakhulu ukuchaneka kwedatha yezinzwa zomhlaba zanamhlanje, zibonelela ngenkxaso yedatha ethembekileyo ngakumbi kwezolimo oluchanekileyo.
Ngokuqhubeka nokuqhubela phambili kweteknoloji, ukuchaneka nokuthembeka kweenzwa zomhlaba kuphucuka rhoqo. Iingcali zicebisa ukuba xa abasebenzisi bekhetha kwaye besebenzisa iinzwa, kufuneka banikele ingqalelo enkulu kumsebenzi wokulinganisa, benze uvavanyo lokuchaneka rhoqo, baqinisekise ukuchaneka kwedatha yokubeka esweni, kwaye banike isiseko sesayensi semveliso yezolimo.
