Isingeniso: Enkathini yokushintsha kwesimo sezulu okwandayo, "ukulima ngokwesimo sezulu" sekuyinto yesayensi enembile. Ithuluzi lesimo sezulu elibonakala lilula kodwa elibalulekile—i-stainless steel tipping bucket rain gauge—okwamanje lidala umsindo emkhakheni wezolimo. Lisuka ekhoneni elingacacile liye emaphethelweni ensimu, liba yiqhawe elingadunyiswanga ekuvikeleni umkhiqizo wezolimo womhlaba wonke.
Ingxenye 1: “Umlindi Othule” Ensimini
Isilinganiso semvula sebhakede elingagqwali eligobhoza amanzi asiyona into entsha ngokuphelele, kodwa ukuthembeka kwaso okumangalisayo kuyinika ithuba elisha lokuphila. Isimiso saso esiyinhloko sokusebenza silula kodwa sihlakaniphile: amanzi emvula ageleza ngomqoqi bese efakwa “ebhakedeni” eliklanywe ngokunemba. Uma amanzi aqoqiwe esefinyelele inani elinqunyiwe (isb., 0.1mm noma 0..2mm), ibhakede ligobhoza ngaphansi kwesisindo salo, lithulula amanzi futhi ngesikhathi esifanayo liqalise isignali kagesi.
Le nqubo iphindaphinda njalo. Ngokubala inani lamaphuzu, ibala inani lemvula kanye nokuqina kwayo ngesikhathi sangempela. Ukwakhiwa kwensimbi engagqwali kuyinika ukuqina okuqinile ukuze imelane nezinto zangaphandle ezinzima, okuqinisekisa iminyaka yokusebenza okuzinzile ezimweni ezinzima zasensimini.
Ingxenye 2: Kungani “Ithrenda”? Ukubuka Isisekelo Sayo Somhlaba Wonke
Ukuthandwa kwale divayisi “eqinile” kuvela ekusetshenzisweni kwayo kabanzi emhlabeni wonke kanye nomthelela oqinisekisiwe. Nakuba iShayina yakhe inethiwekhi enkulu kunazo zonke emhlabeni yeziteshi zezulu ezizenzakalelayo, imibiko yezimboni iqokomisa la mazwe “njengezindawo zokuqala” zalobu buchwepheshe:
- INyakatho Melika (e-United States, eCanada): Emapulazini amakhulu asebenzisa imishini eminingi futhi asebenzisa idijithali, lawa mageji emvula ayindlela ebalulekile “yomthombo wedatha” wezinhlelo zezolimo ezinembile, enikeza ulwazi oluyisisekelo lokuhlela ukunisela.
- IYurophu (isib., iJalimane, iFrance, iNetherlands): Zisetshenziswa kwezolimo ezijulile kanye nezitshalo ezikhethekile njengezivini, ziqapha izimo zezulu ezincane ukuze zisize ekuphathweni kwamanzi okuphumelelayo kanye nemikhiqizo esezingeni eliphezulu.
- IJapan ne-Australia: IJapan iziqasha ukuze zixwayise ngokunembile ngezikhukhula kanye nokuphathwa kwensimu ye-raddy; I-Australia izisebenzisa kakhulu ezindaweni zokulima ezomile ukuze ziqaphe imvula ephumelelayo futhi zilwe nezinselele zesomiso.
Intambo efanayo phakathi kwala mazwe? Imikhakha yezolimo ethuthukisiwe kakhulu enomshikashika oqhubekayo wokuphathwa kwezingozi kanye nokuzuza komkhiqizo.
Ingxenye 3: Umthelela Wayo Oguqukayo Kwezolimo
Ithonya layo lidlulela ngalé nje "kokulinganisa imvula." Lishintsha ngokuyisisekelo izici ezahlukene zokuphathwa kwepulazi:
- 【Ukunisela Ngokunembile, Ukufaka Esikhundleni Somsebenzi Wokuqagela】
Ukunisela kwendabuko kuvame ukuncika kokuhlangenwe nakho, okuholela kalula ekuchithekeni kwamanzi. Manje, ngemininingwane eqondile evela ku-rain gauge, abalimi bazi kahleingakanani imvula etholwe yinsimuLokhu kubavumela ukuthi bakuqhathanise kahle nezidingo zamanzi ezitshalo, okuvumela ukunisela lapho kudingeka. Ukonga amanzi kungathuthukiswa ngo-30%—okuwumthombo obalulekile eminyakeni yesomiso. - 【Ukuvimbela Izinhlekelele, Ukwakha "I-Digital Levee"】
Imvula emfushane nenamandla iyimbangela eyinhloko yokugcwala kwamanzi. I-gauge yemvula yebhakede elingagqwali ibamba izinguquko zobukhulu bemvula ngesikhathi sangempela. Ngaphambi kokuba imvula ibangele umonakalo, uhlelo lwayo lokuxwayisa oluxhunyiwe lungathengela abalimi isikhathi esibalulekile sokuphendula—kungakhathaliseki ukuthi ikhipha amanzi emiseleni noma imisele yokuqinisa—ngokunciphisa ngempumelelo ingozi yokulahlekelwa yisivuno. - 【Izinqumo Ezihlakaniphile, Ukulima Okuqhutshwa Yidatha】
Amarekhodi edatha yemvula yesikhathi eside adala "impahla yedijithali" ebalulekile ensimini. Izazi zezolimo zingasebenzisa lokhu ukuhlaziya amaphethini emvula, ziqondise abalimi ukuthi bathuthukise ukukhethwa kwezitshalo, bakhethe izinhlobo eziningi ezimelana nezikhukhula noma isomiso, futhi bahlele ngokwesayensi ukufaka umquba kanye nokufafaza ukuze kuvinjelwe izakhamzimba ukuthi zingakhukhulwa, ekugcineni kwandise ukusebenza kahle futhi kuncishiswe izindleko.
Ukuqonda Kochwepheshe: Umlimi waseMidwestern US waphawula engxoxweni: “Laba ‘balindi abancane bensimbi’ abathule bangabahloli bedatha bepulazi lami. Abangitsheli nje kuphelaiflana, kodwamalinifuthikunzima kangakanani, ngakho-keokufanele ngikwenze ngokulandelayoLokho kuthinta ngqo isivuno sami kulo nyaka.
Isiphetho: Ukushintsha kusuka ekulinganisweni okungahleliwe okusekelwe kokuhlangenwe nakho kuya esiqondisweni esiqondile, esiqhutshwa idatha, esiboniswe yi-stainless steel tipping bucket rain gauge, kuyisithombe sokuhamba kwezolimo zomhlaba wonke kuya ekuhlakanipheni nasekuqondeni. Kungase kungabi nokubukeka okukhazimulayo, kodwa ngendlela eqondile kakhulu, kwakha umugqa oqinile wezobuchwepheshe wokuzivikela wokulondeka kokudla emhlabeni jikelele. Njengoba ihlanganiswa ngokujulile nobuchwepheshe be-IoT, inani layo lizoqhubeka likhula.
