Kwinkqubo yokuphucula ezolimo, amandla esayensi netekhnoloji ahlala eguqula indlela yokulima yendabuko. Okwangoku, kuvela isixhobo sokuvavanya umhlaba esinobuchule, esinezinto zaso zobugcisa ezizisile utshintsho olungazange lubonwe ngaphambili kwimveliso yezolimo, kwaye kancinci kancinci siba yindoda elungileyo kuninzi lwabalimi ukwandisa imveliso nokwandisa ingeniso nokufezekisa uphuhliso oluzinzileyo.
Ukuqonda ngokuchanekileyo, qhuba ukutsiba kwemveliso
Kwisiseko sokukhulisa iinkozo eMelika, abalimi babeqhele ukugweba imeko yomhlaba ngamava, kwaye iziphumo zokutyala zaxutywa. Ngokungeniswa kwee-capacitive soil sensors, imeko yatshintsha ngokupheleleyo. I-sensor isebenzisa umgaqo we-capacitive sensing ukujonga ukufuma komhlaba, ityuwa, i-pH kunye nezinye izalathisi eziphambili ngexesha langempela ngokuchanekileyo. Umzekelo, kwindawo yokutyala umbona, i-sensor inovelwano kwi-salinity ephezulu yomhlaba, kwaye abalimi bakhawuleza balungise icebo lokunkcenkceshela ngokwempendulo, bonyuse umzamo wokucoca, kwaye banciphise ukuthintela ityuwa ekukhuleni kombona. Ngexesha lokuvuna, imveliso yombona kulo mmandla yayiphezulu ngama-28% kunonyaka ophelileyo, kwaye iinkozo zazigcwele kwaye zisemgangathweni olungileyo. Esi siphumo simangalisayo sibonisa ngokupheleleyo amandla abalaseleyo e-capacitive soil sensors ukukhokela ngokuchanekileyo ukutyala kunye nokusebenzisa imveliso ephezulu yomhlaba.
Ukulungiswa kwezixhobo ukuze kuncitshiswe iindleko zemveliso
Ulawulo lweendleko yeyona nto iphambili ekusebenzeni kwezolimo. Kwifama yemifuno eCambodia, umnini wayekhathazekile yindleko ephezulu yokunkcenkceshela kunye nokuchumisa. Ukusetyenziswa kwe-capacitive soil sensor kuye kwaba sisitshixo sokusombulula ingxaki. Ukubeka esweni ngokuchanekileyo ukufuma komhlaba yi-sensors kwenza ukunkcenkceshela kungabi yimfama. Xa ukufuma komhlaba kungaphantsi komda wemfuno yesityalo, inkqubo yokunkcenkceshela ngokuzenzekelayo iqala ngokuchanekileyo kwaye ilungisa ubungakanani bamanzi ngobulumko ngokusekelwe kwidatha ye-sensor, iphephe ukuchitha amanzi. Ngokuphathelele ukuchumisa, idatha yesondlo somhlaba ebuyiselwe yi-sensors incede abalimi ukuba basebenzise isichumiso xa kuyimfuneko, kunciphisa ukusetyenziswa kwesichumiso ngama-22 ekhulwini. Ngale ndlela, ngelixa kunciphisa iindleko zemveliso, ipaki inemveliso yemifuno ezinzileyo kunye nomgangatho ongcono, kwaye ifumene ukwandiswa kweenzuzo zoqoqosho.
Uphuhliso oluluhlaza oluza kumelana notshintsho lwemozulu
Njengoko sijongene nomngeni onzima wotshintsho lwemozulu, uphuhliso oluzinzileyo lwezolimo lusondele. Kwenye indawo yeziqhamo eOstreliya, imozulu engaqhelekanga rhoqo ichaphazele kakhulu ukukhula kwemithi yeziqhamo. Izinzwa zomhlaba ezinamandla zidlala indima ebalulekileyo apha. Ngexesha lobushushu obuphezulu kunye nembalela, isinzwa silandelela utshintsho kumswakama womhlaba ngexesha langempela, kwaye abalimi bazalise amanzi kwimithi yeziqhamo ngexesha, benciphisa ngempumelelo impembelelo yembalela. Emva kwemvula enkulu kunye nezikhukula, isinzwa siphendula ngokukhawuleza utshintsho lwe-pH yomhlaba kunye nokuvuleka komoya, kwaye abalimi bathatha amanyathelo okuphucula ngokufanelekileyo ukuqinisekisa impilo yeengcambu zemithi yeziqhamo. Ngoncedo lwezinzwa, imveliso yeziqhamo kwindawo evelisayo ihlala izinzile kwimozulu embi, ngelixa inciphisa ungcoliseko lokusingqongileyo olubangelwa kukunkcenkceshela okungafanelekanga kunye nokuchumisa, kwaye ikhuthaza uphuhliso oluluhlaza noluzinzileyo lwezolimo.
Iingcali zezolimo ngokubanzi zikholelwa ukuba izixhobo zokuhlola umhlaba ezikwaziyo ukufunxa zikhokelela ezolimo kwixesha elitsha lokutyala ngokuchanekileyo kunye nokusebenza ngokuchanekileyo kokubeka esweni, iziphumo ezibalulekileyo zokunciphisa iindleko kunye nenkxaso enamandla yophuhliso oluzinzileyo. Ngokukhuthazwa okukhulu kunye nokusetyenziswa kobu buchwepheshe, kulindeleke ukuba buphucule ngokupheleleyo ukusebenza kakuhle kunye nomgangatho wemveliso yezolimo, budale iingenelo ezininzi kubalimi, kwaye bukhusele imeko-bume yezolimo. Kukholelwa ukuba kungekudala, izixhobo zokuhlola umhlaba ezikwaziyo ukufunxa ziya kuba ngumgangatho obalulekileyo kwimveliso yezolimo, zincede imboni yezolimo ukuba ifikelele kwinqanaba elitsha phambili.
