Ubuchwepheshe obusha obubizwa ngokuthi “i-drip tape” buthembisa ukuguqula ubuchwepheshe bokunisela, ukwenza amanzi asebenze kahle futhi kukhuphule isivuno sezitshalo, intuthuko enkulu embonini yezolimo. Okwakhelwe ukubhekana nezinselele ezikhulayo ezihlobene nokuntuleka kwamanzi kanye nezolimo eziqhubekayo, lobu buchwepheshe obushintshayo buhloselwe ukuguqula imikhuba yokunisela emhlabeni jikelele.
Ngokuvamile okubizwa ngokuthi “uhlelo lokunisela oluhlakaniphile”, i-drip tape iyisisombululo sesimanje esihambisa amanzi ngqo endaweni yezimpande zezitshalo zakho. Izindlela zendabuko zokunisela ngezikhukhula zivame ukuholela ekuchithekeni kwamanzi kanye nokungasebenzi kahle, okuholela ekugcwaleni kwamanzi, ukuguguleka kanye nokuphuma kwezakhamzimba. Ukusebenzisa i-emitter drip irrigation tape, inani lamanzi lingalawulwa ukuqinisekisa ukuthi wonke amaconsi amanzi asetshenziswa ngempumelelo, ngaleyo ndlela kuncishiswe imfucuza yamanzi ngamaphesenti angama-50.
Isici esiyinhloko salobu buchwepheshe ukwakheka kwalo okuyinkimbinkimbi. Itheyiphu yenziwe ngezinto eziqinile ezingamelana nezimo zemvelo ezifana namakhemikhali, imisebe ye-UV kanye nokuguguleka ngokomzimba. Ifakwe ama-emitter amancane ngezikhathi ezithile eceleni kwetheyiphu akhipha amanzi ngqo enhlabathini eduze kwezimpande zesitshalo. La ma-emitter angalungiswa ukuze alawule ukugeleza kwamanzi, anikeze abalimi ithuba lokuhlangabezana nezidingo ezithile zezitshalo.
Itheyiphu yokuconsa ye-emitter inikeza izinzuzo eziningana kunezindlela zokunisela zendabuko. Ngokuhambisa amanzi ngqo endaweni yezimpande, itheyiphu inciphisa ukulahleka kokuhwamuka futhi igcina amazinga omswakama wenhlabathi ahambisanayo, okubalulekile ekukhuleni kwezitshalo kahle. Lokhu kutholakala kwamanzi okunembile kunciphisa nengozi yezifo zamaqabunga ezibangelwa amaqabunga amanzi futhi kugwema isidingo sokwelashwa ngamakhemikhali ayingozi. Ngaphezu kwalokho, itheyiphu iyahambisana nezinhlelo zokuvundisa, okuvumela amanzi nomanyolo ukuthi kusetshenziswe ngesikhathi esisodwa, okukhuthaza ukumuncwa okungcono kwezakhamzimba yizitshalo.
Ezindaweni ezithintekile ukushoda kwamanzi, lobu buchwepheshe bokunisela obuqhubekayo bunikeza usizo kubalimi ababenenkinga yokugcina isivuno ngaphambilini. Abalimi manje sebeyakwazi ukonga imithombo yamanzi eyigugu ngenkathi bethola umkhiqizo omkhulu wezitshalo, ngaleyo ndlela bandise ukuzinza komnotho wemindeni yabo kanye nemiphakathi yabo.
Ngaphezu kwalokho, ukwamukelwa kwe-emitter drip tape kunomthelela omkhulu emvelweni. Ngokunciphisa kakhulu ukusetshenziswa kwamanzi nokugwema ukusetshenziswa ngokweqile kwamakhemikhali, lolu hlelo lokunisela olusha lusiza ekuvikeleni imithombo yamanzi endawo nokuvimbela ukungcola kwamanzi agelezayo. Ukulondoloza amanzi nokuvikela impilo yomhlabathi kunegalelo ekusimeni komkhakha wezolimo futhi kunciphisa imiphumela emibi yezolimo ezijulile ezindaweni zemvelo ezizungezile.
Ukutshalwa kwezimali kubuchwepheshe kuye kwanda kancane kancane njengoba abalimi abaningi beqaphela amandla abo. Ohulumeni nezinhlangano emhlabeni wonke bakhuthaza ukusetshenziswa kwe-transmitter drip tape ngokunikeza uxhaso kanye nezinhlelo zemfundo ukukhuthaza ukwamukelwa kwayo. Ngenxa yalokho, ukuthandwa kwale ndlela yokunisela kulindeleke ukuthi kwande, ikakhulukazi ezindaweni ezomile nezingenamanzi lapho izinselele zokuntuleka kwamanzi zinkulu khona.
Ngamafuphi, i-emitter drip tape imelela intuthuko entsha kwezobuchwepheshe bokunisela futhi inikeza ikhambi lenkinga yokuntuleka kwamanzi imboni yezolimo eqhubeka nokubhekana nayo. Ubuchwepheshe bubeka amazinga amasha kwezolimo ezisimeme ngokusatshalaliswa kwamanzi okunembile, ukukhula kwezitshalo okuthuthukisiwe kanye nokonga amanzi okuphawulekayo. Njengoba abalimi emhlabeni wonke bamukela lokhu okusha, ikusasa lokunisela libukeka lithembisa, lithembisa ukuvikeleka kokudla okuthuthukisiwe, ukukhula komnotho kanye nokuvikelwa kwemvelo.
