Mu ulimi wolondola komanso kuyang'anira zachilengedwe, kumvetsetsa momwe nthaka ilili kukusintha kuchoka pa “kuzindikira zinthu molakwika” kupita ku “kuzindikira zinthu molondola”. Kuyeza kwachikhalidwe kwa chinthu chimodzi sikungathenso kukwaniritsa zofunikira pakupanga zisankho zaulimi zamakono. Chifukwa chake, masensa a nthaka okhala ndi zinthu zambiri omwe amatha kuyang'anira chinyezi cha nthaka, pH, mchere ndi michere yofunika nthawi imodzi komanso moyenera akukhala “mpeni wankhondo waku Swiss” kuti atsegule zinsinsi za nthaka ndikukwaniritsa kasamalidwe ka sayansi. Nkhaniyi ifufuza mozama momwe ukadaulo uwu umachitikira.
I. Mfundo Yaikulu Yaukadaulo: Kodi "Mungafufuze Bwanji Zinthu Zambiri Ndi Singano Imodzi"?
Masensa a nthaka okhala ndi magawo ambiri samangolumikiza masensa angapo odziyimira pawokha. M'malo mwake, amagwira ntchito mogwirizana kudzera mu dongosolo logwirizana kwambiri, makamaka pogwiritsa ntchito mfundo zazikulu izi:
Ukadaulo wa nthawi yowunikira nthawi/mafupipafupi a domain yowunikira nthawi - Kuyang'anira chinyezi cha nthaka
Mfundo: Sensor imatulutsa mafunde amagetsi ndipo imayesa kusintha kwawo ikafalikira m'nthaka. Chifukwa chakuti mphamvu ya dielectric ya madzi ndi yayikulu kwambiri kuposa ya zinthu zina m'nthaka, kusiyana kwa mphamvu ya dielectric yonse ya nthaka kumagwirizana mwachindunji ndi kuchuluka kwa madzi m'madzi.
Kuzindikira: Poyesa liwiro kapena kusintha kwa mafunde amagetsi, chinyezi cha nthaka chikhoza kuwerengedwa mwachindunji, mwachangu komanso molondola. Iyi ndi njira imodzi yodziwika bwino komanso yodalirika yoyezera chinyezi cha nthaka pakadali pano.
Ukadaulo wozindikira zamagetsi - kuyang'anira pH, kuchuluka kwa mchere ndi ma ayoni
pH value: Ma transistors osankha ma ion kapena ma electrode agalasi achikhalidwe amagwiritsidwa ntchito. Filimu yofewa pamwamba pake imayankha ma hydrogen ions mu yankho la nthaka, zomwe zimapangitsa kusiyana komwe kungachitike kogwirizana ndi pH value.
Mchere: Kuchuluka kwa mchere m'nthaka kumaonekera mwachindunji poyesa mphamvu yamagetsi ya yankho la nthaka. EC ikakhala yokwera, mchere wosungunuka umachulukanso.
Zakudya: Iyi ndi gawo lomwe lili ndi vuto lalikulu laukadaulo. Pazakudya zofunika monga nayitrogeni, phosphorous ndi potaziyamu, masensa apamwamba amagwiritsa ntchito ma electrode osankha ma ion. ISE iliyonse imakhala ndi yankho losankha ma ion enaake (monga ammonium ion NH₄⁺, nitrate ion NO₃⁻, ndi potassium ion K⁺), potero amayesa kuchuluka kwawo.
Ukadaulo wozindikira kuwala - Nyenyezi yamtsogolo yowunikira zakudya
Mfundo: Njira monga near-infrared spectroscopy kapena laser-induced breakdown spectroscopy. Sensor imatulutsa kuwala kwa mafunde enaake m'nthaka. Zigawo zosiyanasiyana m'nthaka zimayamwa, kuwonetsa kapena kufalitsa kuwalaku, ndikupanga "zala zapadera" zapadera.
Kukhazikitsa: Mwa kusanthula chidziwitso ichi cha ma spectral ndikuchiphatikiza ndi chitsanzo chovuta chowerengera, magawo angapo monga zinthu zachilengedwe m'nthaka ndi kuchuluka kwa nayitrogeni amatha kusinthidwa nthawi imodzi. Iyi ndi njira yatsopano yodziwira yosakhudzana ndi reagent.
II. Kuphatikiza Machitidwe ndi Mavuto: Nzeru za Uinjiniya Zomwe Zili M'malo Olondola
Kuphatikiza ukadaulo womwe watchulidwa pamwambapa mu probe yaying'ono ndikuwonetsetsa kuti ikugwira ntchito bwino kwa nthawi yayitali kumabweretsa mavuto akulu:
Kuphatikiza kwa masensa: Momwe mungakonzere bwino gawo lililonse lozindikira mkati mwa malo ochepa kuti mupewe kusokonezana pakati pa zizindikiro zamagetsi ndi muyeso wa ma ion.
Dongosolo lanzeru la sensa ya nthaka: Dongosolo lathunthu silimangophatikizapo probe yokha, komanso limaphatikiza deta yolemba, gawo loyang'anira mphamvu ndi gawo lotumizira opanda zingwe, ndikupanga netiweki ya sensa ya nthaka yopanda zingwe kuti ikwaniritse kusonkhanitsa deta nthawi yeniyeni komanso kutumiza deta patali.
Kubwezera ndi kuwerengera zachilengedwe: Kusintha kwa kutentha kwa nthaka kungakhudze kwambiri zotsatira zonse zamagetsi ndi zowunikira. Chifukwa chake, masensa onse apamwamba okhala ndi magawo ambiri ali ndi masensa otenthetsera omwe ali mkati ndipo amagwiritsa ntchito ma algorithms kuti apereke chiwongola dzanja cha kutentha nthawi yeniyeni pa ziwerengerozo, zomwe ndizofunikira kwambiri kuti zitsimikizire kulondola kwa deta.
Kuyang'anira mkati mwa malo ndi kukhazikika kwa nthawi yayitali: Sensayi idapangidwa kuti ikwiridwe m'nthaka kuti iyang'anire mkati mwa malo kwa nthawi yayitali, zomwe zikutanthauza kuti iyenera kukhala ndi malo olimba kuti isawonongeke ndi dzimbiri, kupanikizika ndi kusokonezeka kwa mizu. Kuyang'anira ndi vuto lina lalikulu. Kuyang'anira fakitale nthawi zambiri sikokwanira. Kuyang'anira pamalo pa nthaka ya mitundu inayake ndikofunikira kuti mupeze ziwerengero zolondola.
Iii. Makhalidwe Abwino ndi Ntchito: Nchifukwa Chiyani Ndi Ofunika Kwambiri?
Njira yowunikira nthaka iyi "yokhazikika" yabweretsa phindu lalikulu:
Kudziwa bwino za thanzi la nthaka: Sitikuwonanso madzi kapena michere yokha, koma kumvetsetsa ubale wawo. Mwachitsanzo, kudziwa chinyezi cha nthaka kumathandiza kufotokoza momwe michere imayendera bwino; Kudziwa pH kungathandize kudziwa kupezeka kwa michere ya NPK.
Limbikitsani kuthirira ndi feteleza molondola: Perekani chithandizo cha deta yeniyeni ya Variable Rate Technology kuti mukwaniritse kuthirira ndi feteleza nthawi iliyonse yomwe mukufuna, kupititsa patsogolo kwambiri kugwiritsa ntchito bwino madzi ndi feteleza, kuchepetsa ndalama ndikuchepetsa kuipitsa chilengedwe.
Kuzindikira kuwunika kwenikweni kwa chilengedwe nthawi yeniyeni: Pa kafukufuku wa sayansi ndi kuteteza zachilengedwe, imatha kutsatira mosalekeza kusintha kwa magawo a nthaka, kupereka deta yofunika kwambiri yophunzirira kusintha kwa nyengo, kusamuka kwa zinthu zodetsa, ndi zina zotero.
Chiyembekezo cha Mtsogolo
Mtsogolomu, masensa a nthaka okhala ndi magawo ambiri adzakula kuti agwirizane kwambiri (monga kuphatikiza ntchito za tensiometer ya nthaka), kugwiritsa ntchito mphamvu zochepa (kudalira ukadaulo wokolola mphamvu ya nthaka), luntha lalikulu (lokhala ndi ma AI omangidwa mkati kuti azitha kudzizindikira ndi kulosera deta), komanso kuchepetsa ndalama. Ndi kufalikira kwa ukadaulo, udzakhala maziko ofunikira kwambiri paulimi wanzeru komanso kasamalidwe ka nthaka ya digito.
Pomaliza: Chojambulira nthaka chokhala ndi magawo ambiri chakwanitsa bwino kuyang'anira magawo ofunikira a nthaka mogwirizana komanso molondola mwa kuphatikiza ukadaulo wamakono monga TDR/FDR, electrochemistry, ndi optics, komanso pogwiritsa ntchito njira yolumikizirana bwino ndi ma algorithms anzeru. Sikuti ndi chimaliziro cha ukadaulo wokha, komanso chinsinsi choti tipite ku nthawi yatsopano ya ulimi wolondola womwe umasunga zinthu moyenera komanso wosamalira chilengedwe.
