Magetsi okhala ndi nthaka: Kutsegula nyengo yatsopano yaulimi wolondola

M'kati mwaukadaulo waulimi, mphamvu ya sayansi ndi ukadaulo nthawi zonse ikusintha njira yaulimi yachikhalidwe. Pakalipano, chidziwitso cha nthaka capacitive capacitive chikuwonekera, chomwe ndi ubwino wake wapadera waumisiri wabweretsa kusintha kosaneneka pa ulimi waulimi, ndipo pang'onopang'ono kukhala munthu wamanja kwa alimi ambiri kuti awonjezere kupanga ndi kuonjezera ndalama ndikupeza chitukuko chokhazikika.

Lingaliro lolondola, yendetsani kupanga kudumpha
Pamalo olimapo mbewu ku United States, alimi ankakonda kuweruza nthaka mwachidziwitso, ndipo zotsatira za kubzala zinasakanizidwa. Ndi kukhazikitsidwa kwa capacitive nthaka masensa, zinthu anasintha kwathunthu. Sensa imagwiritsa ntchito mfundo ya capacitive sensing kuyang'anira chinyezi cha nthaka, mchere, pH ndi zizindikiro zina zazikulu mu nthawi yeniyeni molondola kwambiri. Mwachitsanzo, m’malo obzala chimanga, kachipangizo kameneka kamamva mchere wambiri wa m’nthaka, ndipo alimi amasintha msangamsanga njira yothirira malinga ndi mmene akuyankhira, kuonjezera mphamvu yothamanga, komanso kuchepetsa kuletsa kwa mchere pakukula kwa chimanga. Pa nthawi yokolola, chimanga m'derali chinali 28% kuposa chaka chatha, ndipo mbewuzo zinali zodzaza ndi zabwino. Chotsatira chodabwitsachi chikuwonetseratu kuthekera kwapadera kwa masensa am'nthaka omwe amatha kuwongolera bwino kubzala ndikupeza phindu lalikulu la nthaka.

Kukhathamiritsa kwazinthu kuti muchepetse ndalama zopangira
Kuwongolera mtengo ndiye ulalo waukulu wa ntchito zaulimi. Pamalo olima ndiwo zamasamba ku Cambodia, mwiniwakeyo anakhumudwa ndi kukwera mtengo kwa ulimi wothirira ndi kuthirira. Kugwiritsidwa ntchito kwa capacitive nthaka sensa kwakhala chinsinsi chothetsera vutoli. Kuwunika bwino kwa chinyezi cha nthaka ndi masensa kumapangitsa kuti ulimi wothirira usakhalenso wakhungu. Pamene chinyontho cha nthaka chili pansi pa chiwongoladzanja chofuna mbeu, njira yothirira yokha imayamba molondola ndikusintha kuchuluka kwa madzi mwanzeru potengera deta ya sensa, kupewa kuwononga madzi. Pankhani ya feteleza, kuchuluka kwa michere ya m'nthaka komwe kumaperekedwa ndi masensa kunathandiza alimi kuthira feteleza pakufunika, kuchepetsa kugwiritsa ntchito feteleza ndi 22 peresenti. Mwanjira imeneyi, ndikuchepetsa mtengo wopanga, pakiyo imakhala ndi masamba okhazikika komanso abwinoko, ndipo yazindikira kukulitsa kwachuma.

Kukula kobiriwira kuti athe kupirira zovuta zanyengo
Poyang'anizana ndi zovuta zowonjezereka za kusintha kwa nyengo, chitukuko chokhazikika cha ulimi chili pafupi. M’dera lina la zipatso ku Australia, nyengo yoipa nthaŵi zambiri yakhudza kwambiri kukula kwa mitengo ya zipatso. Ma sensor a nthaka capacitive amagwira ntchito yofunika kwambiri pano. Panthawi ya kutentha kwambiri ndi chilala, sensa imayendetsa kusintha kwa chinyezi m'nthaka nthawi yeniyeni, ndipo alimi amadzaza madzi a mitengo ya zipatso panthawi yake, kuthetsa chilala. Pambuyo pa mvula yamkuntho ndi kusefukira kwamadzi, sensor imayankha mwachangu pH ya nthaka ndi kusintha kwa mpweya, ndipo alimi amatenga njira zowongolera kuti atsimikizire thanzi la mizu ya mitengo yazipatso. Mothandizidwa ndi masensa, kupanga zipatso kumalo opangira zinthu kumakhalabe kokhazikika pa nyengo yoipa, pamene kuchepetsa kuwonongeka kwa chilengedwe chifukwa cha ulimi wothirira ndi feteleza, ndikulimbikitsa chitukuko chobiriwira ndi chokhazikika cha ulimi.

Akatswiri a zaulimi amakhulupirira kuti ma sensor a nthaka omwe ali ndi capacitive akutsogolera ulimi ku nyengo yatsopano yobzala mwatsatanetsatane ndikuyang'anitsitsa bwino, zotsika mtengo zochepetsera komanso kuthandizira kwambiri chitukuko chokhazikika. Chifukwa cha kukwezedwa ndi kugwiritsa ntchito ukadaulo uwu, akuyembekezeka kuwongolera bwino ntchito zaulimi, kubweretsa phindu lochulukirapo kwa alimi, ndikuteteza chilengedwe chaulimi. Akukhulupirira kuti posachedwapa, capacitive nthaka masensa adzakhala muyezo wofunika kwambiri pa ulimi ulimi, kuthandiza zaulimi kukwaniritsa kudumpha kwatsopano patsogolo.
