Zaka za chilala zikuyamba kupitirira zaka za mvula yambiri kum'mwera chakum'mawa, ulimi wothirira wakhala wofunika kwambiri kuposa moyo wapamwamba, zomwe zimachititsa alimi kufunafuna njira zodziwika bwino zodziwira nthawi yothirira komanso momwe angagwiritsire ntchito, monga kugwiritsa ntchito zodzikongoletsera za nthaka.
Ofufuza pa Stripling Irrigation Park ku Camilla, Ga. , akufufuza mbali zonse za ulimi wothirira, kuphatikizapo kugwiritsa ntchito zowunikira chinyezi cha nthaka ndi telemetry ya wailesi yomwe imayenera kutumiza deta kwa alimi, akutero Calvin Perry, woyang'anira pakiyo.
Perry anati: “Kuthirira kwakula kwambiri ku Georgia m’zaka zaposachedwapa. "Tsopano tili ndi ma pivots opitilira 13,000 m'boma, omwe amathiriridwa maekala opitilira 1,000,000. Chiŵerengero cha madzi apansi pa nthaka ndi magwero othirira madzi apansi ndi pafupifupi 2: 1."
Kuchuluka kwa ma pivots ali kumwera chakumadzulo kwa Georgia, akuwonjezera, ndi opitilira theka la ma pivots apakati m'boma ku Lower Flint River Basin.
Mafunso oyamba omwe amafunsidwa pa ulimi wothirira ndiakuti, ndithirira liti, ndipo ndimagwiritsa ntchito zingati? Akutero Perry. "Timaona ngati ulimi wothirira utayikidwa pa nthawi yake ndi kukonzedwa bwino, ukhoza kuwongoleredwa. Mwachiwonekere, titha kupulumutsa kuthirira kumapeto kwa nyengo ngati chinyezi chanthaka chikuyenera kukhala, ndipo mwina tingapulumutse mtengo wothirira."
Pali njira zambiri zoyendetsera ulimi wothirira, adatero.
"Choyamba, mutha kuchita izi mwachikale potuluka m'munda, kuponda pansi, kapena kuyang'ana masamba omwe amera, kapena mutha kuneneratu za momwe madzi adzagwiritsire ntchito. Mutha kuyendetsa zida zokonzera ulimi wothirira zomwe zimasankha ulimi wothirira potengera kuyeza kwa chinyezi cha nthaka.
Njira ina
"Njira ina ndiyo kuyang'anitsitsa chinyezi cha nthaka pogwiritsa ntchito masensa omwe amaikidwa m'munda. Izi zikhoza kutumizidwa kwa inu kapena kusonkhanitsa kuchokera kumunda," anatero Perry.
Dothi la ku Southeast Coastal Plain likuwonetsa kusinthasintha kwakukulu, akuti, ndipo alimi alibe mtundu umodzi wa dothi m'minda yawo. Pachifukwa ichi, ulimi wothirira bwino m'nthaka imeneyi umatheka bwino pogwiritsa ntchito kasamalidwe ka malo enieni ndipo mwina ngakhale makina ogwiritsira ntchito masensa, akutero.
"Pali njira zingapo zopezera chidziwitso cha chinyezi cha nthaka kuchokera ku ma probes. Njira yosavuta ndiyo kugwiritsa ntchito mtundu wina wa telemetry. Alimi ali otanganidwa kwambiri, ndipo safuna kuti apite m'munda uliwonse ndikuwerenga sensor chinyezi cha nthaka ngati sakuyenera. Pali njira zingapo zopezera deta iyi, "akutero Perry.
Masensawo amagwera m'magulu awiri oyambira, ma sensor a chinyezi cha nthaka ya Watermark ndi zina zatsopano zamtundu wa capacitance za chinyezi cha nthaka, akutero.
Pali chatsopano pamsika. Pophatikiza sayansi ya zomera ndi agronomic, imatha kuwonetsa kupsinjika kwakukulu, matenda a zomera, thanzi la mbewu, ndi zosowa za madzi a zomera.
Ukadaulowu umachokera ku USDA patent yomwe imadziwika kuti BIOTIC (Biologically Identified Optimal Temperature Interactive Console). Tekinolojeyi imagwiritsa ntchito sensor ya kutentha kuti iwunikire kutentha kwa masamba a mbewu yanu kuti mudziwe kupsinjika kwa madzi.
Sensa iyi, yoyikidwa m'munda wa olima, imatenga kuwerenga uku ndikutumiza chidziwitso ku malo oyambira.
Imaneneratu kuti ngati mbewu yanu ithera mphindi zochulukirapo kuposa kutentha kwambiri, ikukumana ndi vuto la chinyezi. Mukathirira mbewu, kutentha kwa denga kumatsika. Iwo apanga ma aligorivimu a mbewu zingapo.
Chida chosinthika
"Telemetry yawayilesi kwenikweni ikutenga datayo kuchokera pamalo omwe ali m'munda kupita ku chojambula chanu m'mphepete mwa gawolo. Mwanjira iyi, simuyenera kulowa m'munda wanu ndi laputopu ya laputopu, kulumikiza ku bokosi, ndikutsitsa deta. Mutha kulandira zambiri. Kapena, mutha kukhala ndi wailesi pafupi ndi masensa omwe ali m'munda, mwina kuyiyika pamwamba pang'ono, ndipo mutha kuyitumiza kuofesi. ”
Papaki yothirira kumwera chakumadzulo kwa Georgia, ochita kafukufuku akugwira ntchito pa Mesh Network, kuyika masensa otsika mtengo m'munda, akutero Perry. Amalumikizana wina ndi mnzake ndikubwerera kumalo oyambira m'mphepete mwa bwalo kapena poyambira pivot.
Zimakuthandizani kuyankha mafunso a nthawi yothirira komanso kuthirira zingati. Ngati muyang'ana deta ya chidziwitso cha chinyezi cha nthaka, mukhoza kuona kuchepa kwa chinyezi cha nthaka. Izi zidzakupatsani lingaliro la momwe watsikira mofulumira ndikukupatsani lingaliro la posakhalitsa muyenera kuthirira.
"Kuti mudziwe kuchuluka kwa momwe mungagwiritsire ntchito, yang'anani zomwe zalembedwazo, ndikuwona ngati chinyontho cha dothi chikukwera mpaka pansi pa mizu ya mbewu yanu panthawiyo."
