Sisitimu Yekudiridza Madonhwe Kuti Ichengetedze Mvura
Munguva yekuchinja kwemamiriro ekunze uye kunetseka kuri kukura kwekuchengetedza nguva, kukosha kwekushandisa zviwanikwa nemazvo kuri kuramba kuchisimbiswa. Chimwe chezvinhu zvakakosha uye zvakakosha pakurima imvura. Kudiridza nemadonhwe kwave mhinduro itsva yedambudziko iri, ichibatsira varimi kuwedzera goho ravo ukuwo ichideredza kushandiswa kwemvura. Chinyorwa chino chichaongorora misimboti yekudiridza nemadonhwe, mabhenefiti ayo, uye kuti tekinoroji iyi yakachinja sei mamiriro ekurima kwemazuva ano.
Kunzwisisa Kudiridza Kwemadonhwe
Kudiridza nemadonhwe, kunozivikanwawo se micro-irrigation, inzira yekuendesa mvura zvakananga kumidzi yemiti nekudonhedza mvura zvishoma nezvishoma kubva mupombi ine network yemapombi, mavharuvhu, uye emitters. Mvura inoendeswa muhuwandu hudiki, hunogara huripo, zvichiita kuti mvura ishandiswe zvakanaka uye inoderedza kupwanyika kwemvura uye kuyerera kwayo.
Sisitimu iyi yakatanga kugadzirwa muIsrael muma1960 naSimcha Blass nemwanakomana wake Yeshayahu. Vakashandisa nheyo dzefizikisi kuti mvura ifambe zvishoma nezvishoma kuburikidza nemapombi epurasitiki zvakananga kumiti, uye kubvira ipapo, nzira iyi yakakura nekukurumidza uye inoshandiswa pasi rese.
Zvikamu Zvikuru zveKudiridza kweDrip
Sisitimu yekudiridza ine zvikamu zvikuru zvakati wandei:
1. Kunobva Mvura: Inogona kuva tangi rekuchengetera mvura, tsime, kana imwe nzvimbo yemvura.
2. Sefa: Kudzivirira zvidimbu zvidiki kuti zvisavhare chinoburitsa mhepo.
3. Pombi: Inodzora kumanikidzwa kwemvura kunodiwa.
4. Vharuvhu Yekudzora: Kudzora nekudzora kuyerera kwemvura.
5. Pombi huru: Inoyerera mvura kubva patsime kuenda kuhurongwa hwese.
6. Emitter/Dripper: Chishandiso chinodonhedzera mvura pazvirimwa nemazvo.
Mashandiro Ekushandisa Drip Irrigation
Masisitimu ekudiridza madonhwe anoshanda nekuisa mvura ine simba shoma papombi huru ine matavi, ine maemitter anotungamira mvura kumidzi yemuti. Huwandu uye kumhanya kwemvura zvinogona kugadziriswa kuitira kuti huwandu hunodiwa chete hupihwe. Izvi zvinobvumira zvirimwa kugamuchira mvura nguva dzose pasina kutambisa mvura.
Mabhenefiti eKudiridza neDrip Irrigation
1. Kuchengetedza Mvura: Iyi nzira inogona kuderedza kushandiswa kwemvura kusvika pa30-50% zvichienzaniswa nenzira dzechinyakare dzekudiridza dzakadai sekudiridza mafashamo kana kudiridza pamusoro pemvura. Nekuti mvura inoenda zvakananga kumidzi yemiti, hapana mvura inorasika nekuda kwekupwanyika kwemvura kana kuyerera kwemvura.
2. Wedzera Kubudirira Kwezvirimwa: Nekupa mvura yakakodzera uye nguva dzose, zvirimwa hazvisangani nematambudziko emvura. Izvi hazvingobatsiri kukura kwezvirimwa chete asi zvinogonawo kuwedzera goho kusvika ku50%.
3. Kuchengetedza Nguva Nebasa: Kudiridza kwemvura uchishandisa otomatiki kunoderedza kudiwa kwekutarisira nekushanda, zvichibvumira varimi kushandisa nguva yavo kune mamwe mabasa.
4. Kuderedzwa kwekushandiswa kweFetiraiza neMishonga Yezvipembenene: Nekudiridza nemadonhwe emvura, fetereza nemishonga yezvipembenene zvinogona kuiswa zvakananga kunzvimbo yemidzi yemiti pamwe chete nemvura (fertigation nechemigation), zvichiwedzera kushanda kwayo uye zvichideredza kushandiswa kwayo.
5. Deredza Kukukurwa Kwevhu: Nekuti mvura inoiswa zvishoma nezvishoma uye nemazvo, njodzi yekukukurwa kwevhu inodzikira zvakanyanya kana tichienzanisa nedzimwe nzira dzekudiridza dzinopa mvura yakawanda.
Kushandiswa mukurima kwemazuva ano
Munyika dzisina mvura yakakwana, dzakadai seIsrael, India, nedzimwe nyika dzinoverengeka dzemuAfrica, kudiridza nemadonhwe kwave nzira huru yekurima. Iyi nzira haingoshandiswi chete mumapurazi makuru asiwo mumagadheni madiki emumba nekurima mumaguta.
1. Israel: Semunhu akatanga basa iri, Israel yakatonga tekinoroji iyi kuburikidza nekutsvaga nekuvandudza nguva dzose. Kubudirira kwavo mukugadzira tekinoroji yekudiridza madonhwe kwakakurudzira dzimwe nyika.
2. India: MuGujarat neMaharashtra, kushandiswa kwemvura yekudiridza kwakabatsira varimi kuwedzera goho remupunga, gorosi nenzimbe nekushandisa mvura zvinobudirira.
3. Africa: Munyika dzinoverengeka dzemuAfrica, mapurojekiti madiki ekudiridza madonhwe emvura anotsigirwa nemasangano epasi rose nehurumende dzemuno kutsigira kuwanikwa kwechikafu nekuderedza urombo.
Matambudziko Okuita
Kunyangwe paine mabhenefiti akawanda, kushandisa madhiri ekudiridza hakusi kusina matambudziko:
1. Mari Yekutanga: Kunyange zvazvo isingadhuri kwenguva refu, mari yekutanga yekuisa inogona kuva yakanyanya kudhura kuvarimi vadiki. Hurumende nemasangano asiri ehurumende anofanira kuita basa rekupa rubatsiro rwemari kana rubatsiro rwemari.
2. Kugadzirisa: Masisitimu ekudiridza madonhwe anoda kugadziriswa nguva nenguva, kusanganisira kucheneswa kwemafirita uye kuongororwa kwemaemitter kudzivirira kuvharika. Kusateerera kwevarimi zvinodiwa pakugadzirisa kunogona kukonzera kutadza kushanda kwesisitimu.
3. Zvipingamupinyi Zvemagariro Nedzidzo: Mune dzimwe nzvimbo, kunzwisisa nekugamuchira matekinoroji matsva kwevarimi kuchiri kushoma. Dzidzo nezvirongwa zvekudzidzisa nguva dzose zvakakosha kugadzirisa dambudziko iri.
4. Kunobva Simba: Mapombi anodiwa kuti mvura ipinde mudhiraivha yemvura inodonhedzwa dzimwe nguva anoda simba risingaperi, iro ringasawanikwa nguva dzose kumaruwa.
Tarisiro Yeramangwana
Pasinei nematambudziko aya, kudiridza nemadonhwe emvura kune ramangwana rakanaka, sezvo kudiwa kwemhinduro dzekurima dzinogara kwenguva refu kuri kuwedzera. Zvimwe zvitsva zvinotarisirwa zvinosanganisira:
1. Kubatanidzwa kweTekinoroji yeIoT (Internet of Things): Zvinoona hunyoro hwevhu, mamiriro ekunze, uye zvinodzora zvinoshandiswa painternet zvinogona kuwedzera kushanda zvakanaka uye kushanda zvakanaka kwezvirongwa zvekudiridza madonhwe.
2. Magadzirirwo Akaderera: Kugadzirwa kwezvinhu zvakachipa uye matekinoroji ezvikamu zvehurongwa kuchaita kuti kudiridza kwemvura kudhure kuve nyore kuvarimi vadiki.
3. Kutarisirwa Kwakanaka Kwezvakatipoteredza: Kushandiswa kwetekinoroji isingakuvadzi nharaunda mukugadzirwa kwemidziyo yekudiridza nekushandisa madonhwe emvura.
4. Kugoverwa Kweruzivo: Mapurogiramu akawanda ekudzidzisa nekutsigira munharaunda kuitira kuti varimi pasi rose vaone mabhenefiti ehunyanzvi uhu.
Mhedziso
Kudiridza nemvura yakadonhedzwa kwaratidza kuti inzira inoshanda uye inoshanda yekushandisa mvura muchikamu chekurima. Nekushandiswa kwakawanda kwechirongwa ichi, tinogona kutarisira kuti chikamu chekurima chepasi rose chive chakasimba uye chinobereka zvakawanda, chichitsigira kugadzirwa kwechikafu kune vanhu vari kukura ukuwo tichichengetedza mvura shoma iri kuramba ichiwanikwa.
