Mukurima kwemazuva ano, kutonga kwakarurama uye budiriro inoenderera mberi zvave zvinhu zvinonyanya kukosheswa nenyanzvi dzezvekurima. Kutarisa hunhu hwemvura chinhu chakakosha pakuita uku, kunyanya nezve soluble carbon dioxide (CO₂). MuUnited States, masensa eCO₂ emhando yemvura anoshandiswa zvakanyanya muzvikamu zvakaita sekurima greenhouse, kurima gungwa, uye masisitimu ekudiridza. Pazasi pane muenzaniso chaiwo unoratidza mashandisirwo chaiwo emasensa eCO₂ emhando yemvura mukurima kweAmerica.
Kumashure
Imba hombe yegreenhouse iri muCalifornia inonyanya kurima miriwo nemaruva anokosha uye yakatarisana nematambudziko ekutarisira kunaka kwemvura uye kukura kwezvirimwa. Nekufambira mberi mune tekinoroji yekurima, imba iyi yakashandisa masensa eCO₂ emhando yemvura kuti ivandudze mamiriro ekurima kwezvirimwa uye kuvandudza goho uye mhando.
Maitiro Anoshanda
Kutarisa Hunhu hweMvura
Chivako chegreenhouse chinoshandisa masensa eCO₂ yemhando yepamusoro yemvura kuti chigare chichitarisa huwandu hwecarbon dioxide mumvura yekudiridza panguva yekudiridza nekuberekesa. Nekutevera huwandu hweCO₂ mumvura, purazi rinogona kunzwisisa zviri nani shanduko muacidity yemvura (pH) uye mhedzisiro yayo pakukura kwezvirimwa.
Sisitimu Yekudiridza Yakangwara
Kana masensa achiona kuwedzera kwehuwandu hweCO₂ mumvura, sisitimu inogadzirisa yega nguva yekudiridza. Kugadziriswa uku kwega kunogadzirisa huwandu hwemvura nezvinovaka muviri, zvichiita kuti zvirimwa zvikure mumamiriro ezvinhu akanaka. Semuenzaniso, kana huwandu hweCO₂ hwakaderera, sisitimu inowedzera huwandu hweCO₂ kukurudzira photosynthesis, nokudaro zvichiwedzera mwero wekukura kwezvirimwa.
Kufanotaura Kwegoho Rezvirimwa
Nekuongorora ruzivo rwekare pamwe chete neruzivo rwemhando yemvura panguva chaiyo, vanotarisira magreenhouse vanogona kufanotaura mafambiro ekukura uye goho rinogona kuwanikwa pazvirimwa zvavo. Ruzivo rwunopihwa nemasensa eCO₂ emhando yemvura runotsigira kuumbwa kwesarudzo dzekutarisira kurima dzakarurama, dzakadai sekuronga nguva yakakodzera uye yakakodzera yekuberekesa nekudiridza.
Mhedzisiro uye Mhinduro
Mushure mekushandisa CO₂ yekutarisa hunhu hwemvura, imba yekuchengetera zvirimwa yakawedzera zvakanyanya. Mugore rekutanga rekuisa masensa, goho rakawedzera neinenge 20%, uye hunhu hwezvirimwa hwakavandudzikawo zvakanyanya. Vatungamiriri vakataura kuti kutarisa panguva chaiyo nekugadzirisa mamiriro ekudiridza kwakavabvumira kupindura nekukurumidza kumatambudziko ekukura, kuderedza marara uye kuwedzera kushanda zvakanaka kwezviwanikwa zvemvura.
Tarisiro Yeramangwana
Sezvo matekinoroji ekurima achiramba achifambira mberi, kushandiswa kwemasensa eCO₂ emhando yepamusoro yemvura kuchawedzera kusvika kune mamwe matunhu ekurima, anosanganisira kurima gungwa, kuongorora ivhu, nedzimwe nzvimbo dzekurima zvirimwa. Nekubatanidza huchenjeri hwekugadzira uye ongororo yedata guru, ramangwana rekurima rinovimbisa kushanda zvakanaka uye kugarika, zvichibatsira shanduko mukugadzirwa kwekurima.
Mhedziso
Kuburikidza nekushandisa masensa eCO₂ emhando yemvura mugreenhouse yeCalifornia, tinoona kuti kurima kwemazuva ano kunoshandisa sei tekinoroji kusimudzira kugona kwekugadzira uye mhando yezvirimwa. Izvi hazvingobatsiri chete pakugadzira zvekurima asiwo zvinopa ruzivo rwakakosha rwekusimudzira budiriro yekurima inoenderera mberi. Sezvo tekinoroji ichiramba ichivandudzika, kutarisa hunhu hwemvura kwagadzirira kuva chishandiso chakakosha mukutarisira kurima mune ramangwana.
Tinogonawo kupa mhinduro dzakasiyana-siyana dze
1. Mita inobatwa nemaoko yemhando yemvura ine maparameter akawanda
2. Sisitimu yeFloating Buoy yemhando yemvura ine maparameter akawanda
3. Bhurashi rekuchenesa otomatiki re sensor yemvura ine ma parameter akawanda
4. Seti yakakwana yemaseva nesoftware isina waya module, inotsigira RS485 GPRS /4g/WIFI/LORA/LORAWAN
