Indasitiri yekurima yafambira mberi zvikuru mumakore achangopfuura, uye imwe yenzira dzakadaro ndeyekuiswa kwetepi yekudiridza ine mitsetse miviri. Tekinoroji iyi itsva yakachinja nzira iyo varimi vanodiridza zvirimwa zvavo uye inopa mabhenefiti akawanda pane nzira dzechinyakare dzekudiridza. Nekukwanisa kwayo kuchengetedza mvura, kuwedzera goho rezvirimwa uye kuderedza mari yevashandi, tepi yekudiridza ine mitsetse miviri iri kuwedzera kufarirwa nevarimi pasi rese.
Tape yekudiridza ine mitsetse miviri (double line drip tape) inzira yekudiridza ine mitsetse miviri yakafanana yakaiswa pamusoro pevhu, ine maemitter akaiswa nguva nenguva. Iyi nzira inoita kuti mvura igoverwe zvakanaka, zvichiita kuti zvirimwa zviwane hunyoro hwazvinoda zvakananga munzvimbo yemidzi. Kusiyana nenzira dzechinyakare dzekudiridza pamusoro dzinokonzera kuyerera kwemvura uye kupwanyika kwemvura, tape yekudiridza ine mitsetse miviri (twin-line drip tape) inoendesa mvura zvakananga kumidzi yemiti, zvichideredza zvakanyanya marara emvura.
Chinhu chikuru chakanakira tepi yekudonhedza ine mitsetse miviri ndiko kugona kwayo kuchengetedza mvura. Nekuendesa mvura zvakananga kumidzi yemiti, nzira iyi yekudiridza inobvisa kurasikirwa nemvura kuburikidza nekubuda kwemvura uye kuyerera kwemvura, nokudaro zvichiwedzera kushanda zvakanaka kwemvura. Tsvagiridzo inoratidza kuti tepi yekudonhedza ine mitsetse miviri inogona kuchengetedza kusvika ku50% yemvura zvichienzaniswa nenzira dzechinyakare dzekudiridza pamusoro pemvura. Nekushomeka kwemvura kuri kuramba kuchinetsa munzvimbo dzakawanda, tekinoroji iyi inopa mhinduro yekuchengetedza nharaunda mukutarisira mvura yekurima.
Pamusoro pezvo, tepi yekudiridza ine mitsetse miviri yakaratidzwa kuti inowedzera goho rezvirimwa uye mhando yazvo. Nekupa mvura nguva dzose munzvimbo yemidzi, nzira iyi yekudiridza inovandudza kukura kwezvirimwa. Zvakaonekwa kuti zvirimwa zvinodiridza netepi yekudiridza ine mitsetse miviri zvine kukura kuri nani kwemidzi, kuwedzera kunwa kwezvinovaka muviri, uye kuderedza kukura kwemasora. Zvinhu izvi zvinobatsira kuwedzera goho rezvirimwa uye kuvandudza kunaka kwezvirimwa, zvichizobatsira varimi.
Pamusoro pekuchengetedza mvura uye kuwedzera goho rezvirimwa, tepi yekudiridza ine mitsetse miviri inewo zvakanakira kuchengetedza vashandi. Kusiyana nenzira dzekudiridza dzechinyakare dzinoda basa rakawanda remaoko, tepi yekudiridza ine mitsetse miviri inogona kuiswa nyore nyore uye kushandiswa pasina kupindira kwakanyanya nemaoko. Kana sisitimu yangoiswa, varimi vanogona kuita otomatiki maitiro ekudiridza uye kudzora kuyerera kwemvura kuburikidza nezvishandiso zvakasiyana-siyana zvetekinoroji. Izvi hazvingoderedzi chete kudiwa kwekutarisa nguva dzose uye kushanda nemaoko, asiwo zvinobvumira varimi kutarisa pane zvimwe zvinhu zvakakosha zvemabasa avo ekurima.
Tape ye double line iri kuramba ichizivikanwa pasi rose. Munyika dzakadai seIndia, China neUnited States, varimi vagara vachishandisa tekinoroji iyi, vachiziva kuti inogona kuvandudza mashandiro ekudiridza uye kuderedza matambudziko ekushomeka kwemvura. Hurumende neindasitiri yezvekurima vari kukurudzirawo kushandiswa kwetape ye double-line drip kuburikidza nezvirongwa zvakasiyana-siyana zvekukurudzira nekudzidzisa zvine chinangwa chekugadzira chikamu chekurima chinogara kwenguva refu uye chinobudirira.
Kugona kwayo kuchengetedza mvura, kuwedzera goho rezvirimwa uye kuderedza mari yevashandi kunoita kuti ive sarudzo inokwezva varimi pasi rese. Sezvo kurima kuri kuramba kuchitarisana nematambudziko ane chekuita nekushaikwa kwemvura uye kuchengetedzeka kwezvakatipoteredza, kushandiswa kwenzira itsva dzekudiridza dzakadai se double-line drip tape kwakakosha kune ramangwana rekurima.
