Indasitiri yezvekurima yakafambira mberi zvikuru mumakore achangopfuura, uye imwe budiriro yakadaro kuiswa kwekaviri-line drip tepi yekudiridza.Michina yechizvino-zvino iyi yakasandura madiridziro anoita varimi mbesa dzavo uye inopa pundutso dzakawanda pamusoro pemadiridziro echinyakare.Nekukwanisa kwayo kuchengetedza mvura, kuwedzera goho uye kuderedza mari yevashandi, kaviri-line drip tepi iri kuwedzera kufarirwa nevarimi pasi rose.
Double line drip tepi idrip irrigation system inosanganisira kushandiswa kwemitsara miviri inofambirana yetepi yekudiridza yakagadzikwa pamusoro pevhu, nemiti inoiswa nguva nenguva.Iyo sisitimu inovimbisa kugovera kwemvura kwakanyatsoita, ichibvumira zvirimwa kuwana mwando wavanoda zvakananga munzvimbo yemidzi.Kusiyana nenzira dzechinyakare dzekudiridza pamusoro pemvura dzinokonzera kuyerera kwemvura uye kuputika, tepi yekudonha-mitsetse miviri inoendesa mvura yakananga kumidzi yechirimwa, ichideredza zvakanyanya tsvina yemvura.
Kubatsira kukuru kwekaviri-line drip tepi kugona kwayo kuchengetedza mvura.Nokuendesa mvura zvakananga kumidzi yemiti, iyi nzira yekudiridza inobvisa kurasikirwa kwemvura kuburikidza nekuputika uye kumhanya, nokudaro kuwedzera kushandiswa kwemvura.Tsvagiridzo inoratidza kuti tepi yekudonha-mitsetse miviri inogona kuchengetedza kusvika 50% yemvura zvichienzaniswa nemaitiro echinyakare ekudiridza pamusoro.Nekushomeka kwemvura kuri kuramba kuchiwedzera kunetsa mumatunhu mazhinji, tekinoroji iyi inopa mhinduro yakagadzikana yekutonga kwemvura yekurima.
Pamusoro pezvo, tepi yekudonha-mitsetse miviri yakaratidza kuwedzera goho nemhando.Nekupa mvura inowirirana munzvimbo yemidzi, iyi yekudiridza inogonesa kukura nekukura kwechirimwa.Zvakaonekwa kuti mbesa dzakadiridzwa nematepi ekudiridzira ane mitsara miviri ine midzi iri nani, kuwedzera kutorwa kwechikafu, uye kuderedza kukura kwesora.Zvinhu izvi zvinobatsira kuwedzera goho nekusimudzira mhando yembesa, zvichizobatsira varimi.
Pamusoro pekuchengetedza mvura uye kuwedzera goho regoho, tepi yekudiridza inodonhedza mitsetse miviri ine zvakanakira kuchengetedza basa.Kusiyana nenzira dzechinyakare dzekudiridza dzinoda basa rakawanda remawoko, tepi yekudonha ine mitsetse miviri inogona kuiswa nyore nyore uye kushandirwa pasina kupindira kwemaoko.Kana iyo system yaiswa, varimi vanokwanisa kuitisa nzira yekudiridza uye kutonga kuyerera kwemvura kuburikidza neakasiyana matekinoroji maturusi.Izvi hazvingoderedzi kudiwa kwekugara uchitariswa nekushanda kwemaoko, asiwo zvinoita kuti varimi vatarise zvimwe zvakakosha pakurima kwavo.
Kaviri mitsetse yekudonha tepi iri kuramba ichizivikanwa pasi rese.Munyika dzakaita seIndia, China neUnited States, varimi vakashandisa ruzivo urwu zvakanyanya, vachiona kuti hunogona kuvandudza madiridziro uye kuderedza dambudziko rekushaikwa kwemvura.Hurumende neindasitiri yezvekurima vari kusimudzirawo kutambirwa kwedouble-line drip tepi kuburikidza nekukurudzira kwakasiyana-siyana uye zvirongwa zvedzidzo zvine chinangwa chekuumba chikamu chezvekurima chinogara chiripo uye chine pundutso.
Kugona kwayo kuchengetedza mvura, kuwedzera goho uye kuderedza mari yevashandi kunoita kuti ive sarudzo inokwezva kuvarimi pasi rese.Sezvo kurima kuri kuramba kuchitarisana nematambudziko ane chekuita nekushaikwa kwemvura uye kuchengetedza kwezvakatipoteredza, kutorwa kwemitoo mitsva yemadiridziro yakaita sedouble-line drip tepi yakakosha kune ramangwana rekurima.
