Pakupita patsogolo kwakukulu pa kayendetsedwe ka madzi mu ulimi, kugwiritsa ntchito zida zoyezera madzi za radar kwapereka zotsatira zabwino m'mafamu onse ku United States. Zipangizo zatsopanozi, zomwe zimagwiritsa ntchito ukadaulo wa radar poyesa kuyenda kwa madzi, zasintha kwambiri alimi omwe akuyesetsa kugwiritsa ntchito bwino madzi, kukulitsa zokolola, komanso kuthana ndi mavuto omwe amabwera chifukwa cha kusintha kwa nyengo.
Nthawi Yatsopano mu Kasamalidwe ka Ulimi Wothirira
M'mbuyomu, kasamalidwe ka madzi mu ulimi kadalira njira zoyezera madzi zomwe nthawi zambiri sizili zolondola komanso zogwiritsa ntchito nthawi yambiri. Komabe, zida zoyezera madzi za radar zimapereka njira yolondola komanso yosasokoneza kwambiri yoyezera madzi nthawi yeniyeni m'makina othirira. Pogwiritsa ntchito ukadaulo wa radar wa microwave, zida zoyezera madzizi zimatha kuyang'anira bwino momwe madzi amagwiritsidwira ntchito m'mapaipi, ngalande, ndi m'mitsinje popanda kufunikira kusintha kulikonse kwa zomangamanga zomwe zilipo.
Mapulojekiti angapo oyesera m'maiko akuluakulu a zaulimi—California, Texas, ndi Nebraska—asonyeza kuti zipangizozi zimatha kupatsa alimi deta yofunika kwambiri, zomwe zimawathandiza kupanga zisankho zolondola pankhani yogwiritsa ntchito madzi. Mphamvu imeneyi ndi yofunika kwambiri munthawi yomwe chilala chikuwonjezeka komanso nkhawa zokhudzana ndi kusowa kwa madzi.
Nkhani Zopambana Zochokera Kudera Lonse
Alimi omwe akuchita nawo mapulogalamu oyesera anena kuti kusintha kwakukulu pa njira zoyendetsera madzi kukuchitika. Ku Central Valley ku California, komwe kukukumana ndi chilala chachikulu, alimi omwe amagwiritsa ntchito zida zoyezera madzi ndi radar adawona kuwonjezeka kwa 20% pakugwiritsa ntchito bwino ulimi wothirira. Mwa kulandira deta yolondola ya madzi nthawi yeniyeni, alimiwa amatha kusintha nthawi yawo yothirira malinga ndi zosowa za mbewu, kuchepetsa kuwononga madzi komanso kukulitsa thanzi la mbewu.
Ku Texas, gulu la alimi a thonje linakhazikitsa zida zoyezera madzi kuti liziyang'anira momwe madzi amagwiritsidwira ntchito nthawi yomwe akukula kwambiri. Zotsatira zoyambirira zikusonyeza kuti alimi anachepetsa kugwiritsa ntchito madzi ndi pafupifupi 15-25% pamene akusunga kuchuluka kwa zokolola. "Kulondola kwa ziwerengerozi kumatithandiza kukhala ndi luso lochita zinthu mwanzeru ndi njira zathu zothirira. Zasintha momwe timaganizira za kugwiritsa ntchito madzi," anatero mlimi wakumaloko Miguel Rodriguez.
Chigawo cha Midwest nachonso chagwiritsa ntchito ukadaulo uwu, ndipo alimi ku Nebraska akuwonetsa kuti pali ubwino waukulu. Pogwiritsa ntchito makina oyezera madzi a radar, kugwiritsa ntchito madzi ambiri panthawi yofunika kwambiri kwachepa, zomwe zathandiza kuti madzi asungidwe mamiliyoni ambiri m'mafamu omwe akutenga nawo mbali.
Zotsatira za Zachilengedwe ndi Zachuma
Zotsatira za chilengedwe pokonza njira zothirira pogwiritsa ntchito makina oyezera madzi ndi zazikulu. Akatswiri akuti kusamalira bwino madzi kungachepetse kwambiri madzi othamanga komanso kuipitsa zakudya zomwe zimakhudza misewu ya m'madzi ndi zachilengedwe zapafupi.
Komanso, phindu la zachuma kwa alimi ndi lalikulu. Chifukwa cha kuchepa kwa ndalama zogulira madzi komanso zokolola zabwino, phindu la ndalama zomwe alimi ena apeza pasanathe chaka chimodzi. "Sizokhudza kusunga madzi okha; koma ndikusunga ndalama ndikuwonetsetsa kuti minda yathu ikuyenda bwino kwa nthawi yayitali," adatero Laura Thompson, katswiri wa zaulimi ku United States Department of Agriculture (USDA).
Mavuto ndi Ziyembekezo Zamtsogolo
Ngakhale zotsatira zabwino zachitika, kugwiritsa ntchito makina oyezera madzi a radar kumakumana ndi mavuto, kuphatikizapo ndalama zoyambira zoyikira ndi njira yophunzirira yogwirizana ndi ukadaulo watsopano. Alimi ena akuwonetsa kukayikira kusintha njira zachikhalidwe, koma omwe asintha amanena kuti awona mwachangu ubwino wake.
Dipatimenti ya zaulimi ya USDA ndi boma ikulimbikitsa kugwiritsa ntchito makina oyezera ma radar ndikufufuza njira zothandizira kuyika kwawo m'mafamu ang'onoang'ono. Pamene deta yochulukirapo ikupezeka, kulengeza kuti anthu ambiri azigwiritsa ntchito mankhwalawa kukuyembekezeka kukulirakulira.
Mapeto
Kugwiritsa ntchito makina oyezera madzi a radar ndi nthawi yofunika kwambiri pakufuna njira zokhazikika zaulimi ku United States. Pamene alimi akukumana ndi mavuto awiri okhudza kukulitsa zokolola ndi kusunga madzi, ukadaulo watsopanowu uli ndi kuthekera kotsogolera njira yopita ku tsogolo laulimi lothandiza komanso losamalira chilengedwe. Kugwirizana kosalekeza pakati pa alimi, ofufuza, ndi opanga ukadaulo kudzakhala kofunikira kwambiri pakugwiritsa ntchito bwino luso la chitukuko chodalirikachi pakuwongolera madzi aulimi.
Kuti mudziwe zambiri zokhudza makina oyezera madzi ndi njira zogwiritsira ntchito ulimi wokhazikika, pitani ku webusaiti yovomerezeka ya USDA kapena funsani ofesi yanu yowunikira ulimi.
Kuti mudziwe zambiri zokhudza sensa ya radar ya Madzi,
