Ko ēhea ngōkē e eke ana ki te pāpaku ahumahi ōrite? Ko tā mātou tau hōu Iwob-2"

Te Take E Mahi Ana Te Whakapai: Te Pānga Whānuitanga me te Ārahi Ake o te Whakapai Kāore anō kia Ōrite

Ko te whakawhitinga o ngā wai i ngā pāmu he mea nui ake i te inenga anake i tētahi pepa mō ngā inenga inihua. Hei tikanga, he pānga ki te ara ka tipu ai ngā hua, ki te arataki e whakamahia ana ngā rāwekenga, ā, kit e mutunga, ki te momo utu e taea ai ngā kainoho. Ko ngā mara e whakauria ana ngā wai kore whakaritenga ka hua ngā raruraru katoa. Ngā wāhanga e iti ana te wai ka mau ngā rākau ki te mate, ka iti ake te huinga, ā, ko ngā wāhanga e nui ana te wai ka pau ai te hiko, ka horo i ngā punaha paihere o te oneone, ā, ka wātea ai ngā waka huaketia kia huri noa. E whakaatu ana ngā rangahau mō te kore whakatika i ngā pūpahi, ka heke ngā hua i somewhere between 15 to maybe even 30 percent because different spots in the same field have wildly varying moisture levels. Ka hua tēnei ki ngā ngaro moni matua mō ngā mara takitahi. Mai i te āhuatanga moni, ka taea e ngā tikanga whakapōharu kino te piki ake i ngā utu tōtoko tae atu ki te 25 percent. Ko ngā kainoho hoki e tend ana ki te whakauri i ētahi atu kaiwhakapai i te mea e ngana ana rātou ki te whakatika i ngā punaha e horo ana i ngā wāhi e nui ana te wai.

Ko te purupuru Iwob-2 e whai take ana i ēnei wero mā te inihua tikanga. Ko tōna wehenga pani tauwhiro ka whakaiti i ngā wāhi maroke me ngā wāhi paru, e hoatu ana i ēnei tāpaetanga e toru:

• Te whanaketanga ake i te whakamahi āhuarangi ua , e whakaiti ana i te here ki te whakapaiāhua
• He utu iti ake mō ngā putunga mō te hiko, te mahi, me ngā kemihere taraiwa
• Te kounga ōrite ake o te hua , e tautoko ana i te whakauru ki ngā maakete matua

Ina whiwhi ngā tīmata i ngā rārangi mātai waimā, kāore anō rātou i pēnei i ērā mōhio e oho ana ka ngenge ai tō rātou mana ārai mate. Hei tauira, ngā mara kotone. Kua kitea ngā mara i heke ake ai te wehenga waimā i raro i te 80% kua piki ake te raru ki te mate pokipoki huarākau, tērā pea te rua tekau mā waru ngā raru ki ngā mara i ōrite ai te ua. Mā te whakanui ake i te wehenga waimā mā te 10 ōrau anake, ka piki ake te moni hoko i waenganui i te 6 ki te 9%. CHe aha? Nā te mea ka tiaki te whakahaere i te waimā i ngā hua tīmata, ā, ko te itinga i ngā rawa kua pau. Ko ngā kaiwhetū mātai e whai nei kia ōrite te wehenga waimā i roto i ō rātou mara, kei te wāhi e huinga ana te matauranga mātai tipu me te inihiniere pai. Kei te pai tēnei momo aronga ki ngā taipitopito, ehara i te mea noa mō ngā tipu engari kei te nuinga hoki hei mea matua mō te hokohoko kaiwheketia me te whakahaere taiao tika i tēnei wā.

Te ine i te Ōrite: CU, DU, me SC—He aha ia metirikiti e whakaatu nei mō te Iwob-2 Sprinkler

Ko te Āhuatanga Kotahi (CU): Me pēhea te Iwob-2 e āki ana i te ≥92% i raro i ngā tikanga pūtōrino whakauru

Ko te Āhuatanga Kotahi, nō te poto CU, e mōhiotia ana e ngā kaiwhakatō hei ine i te āhua o te wātea o te wai ki runga i ngā mara. Kua tūhono te tauira Iwob-2 i ngā inenga CU e pānui ake i te 92% i ngā whakaurunga pūtōrino noa, e pā ana ki te tohu 85% nā te nuinga e whakaarohia ana hei pai mō te whakaweketanga mara. He aha te take? Nā, ēnei karu wai kei a rātou ngā parirau hoahoa motuhake e pupuri ai i ngā waimanawa kia torotoro, kaua ko te pekapeka, nō reira he iti ake te wai e ngaro ana ki te rangi me te nui ake e tae atu ana ki ngā wāhi e hiahiatia ana. I tētahi tau kua pahure ake, i mahia ētahi whakamātautau ki runga i tēnēi tekau mā rua ngā pūnaha pūtōrino e noho ana ki ngā wāhi maroke. I kitea e ngā kaiwhakatō tētahi whakapakari o te 7% i ngā hua kaipara i te wā i huri rātou mai i ngā pūnaha tawhito i paingia ai anake i raro i te 85% āhua e ai ki ngā rangahau i tākarotia e Irrigation Science Journal i te 2023.

Te Ūranga Tōpū (DU) me te Koirana Tātai (SC): He aha ai ka pēra te whakaiti a Iwob-2 i te wai e tukuna ana neke atu i te 24%

Ko te Ūranga Tōpū, nō te DU te takotoranga poto, e neke ana hoki i te āhua o te wai e taraihia ana mā runga i te mara, ina koa e titiro ana ki te kapa tuawhā kei raro i te uara toharite mā te rohe katoa. I te wā anō, ko te Koirana Tātai e whakaatu ana ki te aha te wai e hiahiatia ana kia tāpiri ki ngā wāhi parurenga kia tōtika ai te āhua. Ko te pūnaha hou, Iwob-2 e eke ana ki te rākau DU o te 84% tata, ā, e pupuri ana i te uara SC o te 1.19 tata. Ka hua mai ēnei tau i te whakahaere pai ake i ngā tātai whakapau wai, ā, ka whakaiti hoki i te wai e waste ana, aronga ki te 18 ki te 24% kei te tāpiri atu i ngā pūnaha tākarotia e whakamahia ana i tēnei wā. He aha te mea e wātea ai tēnei? Āta tirohia ētahi take matua mō ēnei whakapai ake.

• Whakahaere pēpihi-itū (2.8–3.5 bar), e hāngai ana i ngā karu wai iti, ū
• Ngā rerekētanga karuwha e pupuri ana i te DU >80% āke hoki i te 5 m/s te hihiko o te hau

Ko te whakapainga a SC e hāngai ana ki ngā moni e penapena ana: ka penapena ngā kaiwhakatōhutia tāpoi $11–$17 ia tau mō ia ekere, pērā anō hoki te whakamahinga i ngā herekore waimāori mo ngā tipu [FAO Water Reports, 2024].

Te Mahi a Iwob-2 Sprinkler i ngā Tikanga Tāone Rerekē

Ngā Whiwhinga DU mō te Oneone: +12–27% nui ake i ngā rotary sprinkler tawhito i runga i te loam, the clay, me te kōhatu pūpahi

Whakaatu ana te punaha Iwob-2 i ngā whakapai ake i te wātea o te horapa o te wai ki ngā momo oneone rereke. Kua whakaaturia e ngā tāwhaiwhai i ngā mara pūmau ngā whakapai ake i te whanui o te horapa i te roanga o te 12% ki te 27% ina mātai ki ngā purunga rotary tawhito e mahi ana ki te oneone loamy, ngā oneone kirihau hoki, ā, ko ngā wāhi onepū anō hoki. Ko te aronga mataara, kātahi kaitekau kaiteka i te wai e 18% ki te 24% i ngā mara e rerekē ana ngā tikanga mai i tētahi wāhi ki tētahi. Ko te ara e mahi ana ko ngā karuturi iti e mātai ana ki te tere e huinga ana te oneone i te pouri. Ka āki ai ki te heparu i ngā raru o runga i ngā takiwā kirihau nehenehe, ā, ka aukati hoki i te nuinga o te wai e hoki ana ki raro ki ngā takiwā onepū e tere ai te pātiki.

Te Māia ki te Hau: Te AU tinowari >88% i te tere hau 3 m/s nā te iti te hiko (2.8–3.5 bar), te hoahoa karuturi iti

Kei te whakahaere i te 2.8–3.5 bar, ko te Iwob-2 e mau ana i te DU e hāngai ake i te 88% i ngā hau e taea ana e 3 m/s—e pai ake i ngā pūnaha tawhito, nā reira ka ngaro noa i te 15–30% te ūrite i raro i ngā tikanga tōronga. Ko tōna haerenga tauira korehu me te ara e iti ana te hau e huri ana, e āki ai te tautautika waimoana i te wā o ngā putanga hau mōmona kia kaua ai e wātea ngā wāhi kaua ai hoki te hara rawa.

Te whakamahi i te Iwob-2 Sprinkler mō te Ūrite Tino: Ngā Aratohu Mātau mō te Daringa me te Tūranga

Ko te whiwhi i ngā whakapai ake o te taurite mai i te Iwob-2 e toru ngā take matua: te kōwhiringa i ngā taputapu tika, te whakahaere i te pēhanga tōtika, me te hoahoa i te takotoranga tika. Ina kōwhiri ngā tīma kaiwhakaari he rahi rānei, he iti rānei, ka taea pea te ngaro i te 19% o te taurite tākarotia. He nui te painga. Ko te mea matua ko te whakaaetanga i ngā taipitopito o ngā taputapu ki te momo oneone e mahi ana mātou, me te wai e hiahiatia ana e ngā taraiwa. E whai nei ngā kaihanga nui i ēnei tūtohi āwhina e whakaatu ana i ngā mea pērā i te hia pērā o te pēhanga e hiahiatia ana mō ngā oneone kiripipi, arā e 3 bars pea. Mō te tawhiti i waenganui i ngā karu wai, ko ngā whakaranurangu takirua e pai ake ana i ngā tapawhā noho, nā te mea ka whai anuanu ake ngā tau o te karu wai. Ka āwhina tēnei i te kino o te kīnaki wai ki ngā tapa o ngā mara, ā, ka pupuri i te tākarotia ki runga ake i te 87%, ā, ahakoa kei ngā taha maunga, kei te whenua hāpuku rānei.

Ina tūhuratia ngā tikanga o te hau, me ētahi whakarerekenga i mua. Mō ngā tere hau noa rānei e pēnā iho i te 3 mita ia sekene, ka pai kia mau ki te 50% nekenga atu ki runga i te kīanga. Arā, mēnā ka taea e te karuwhai te eke ki te 24 mita, me wehe ngā kīanga ki te 12 mita. Engari mēnā ka pakaru ake te hau, ka iti ake te wehenga ki te 15 ki te 20 ōrau, nō reira whakaaro ki te tāpiri i tētahi momo arataki hau. Heoi anō, he nui te take o ngā tautuhinga toki. Me mau ki te rohe tautukuna mō te punaha Iwob-2, e waewae ana i waenganui i te 2.8 ki te 3.5 bars. Ka iti ake te toki ka iti ake te wai e ngaro ana nā te parurenga, ā, ka taea e ngā karuwhai iti rawa te uru whakadunia ki roto ki te oneone kotahi. Ko ngā kaiwhakatōrea i huri, e ripoata ana kia 24% te wai i penapena ai i te tāpiritanga atu ki ngā punaha rotary tawhito, e mārama ana pea tēnā ina titiro ki te nuinga o ngā wai e ngaro ana i ēnei tikanga tawhito.

Rārangi Mataara Matua:

• Kīanga & Toki : Manaaki ki ngā tūtohi a te kaihanga—ka paku ake te DU ina huringa te toki
• Tauanga : Whakamahia te rārangi āhuatanga takirua me te %50 o te tāwhai pūpahi koretake; whakapressa ngā wā kua neke ake ai te hau i te 3 m/s
• Tirotiro : Horomia ngā pūpahi ia rua wiki ki te whakakore i te porotiti o te tāwhai

Mā te arataki i ēnei arataki ka tūhono te uara o Iwob-2: ko te DU roa >88% e mōhiotia ana kaiteka te whakamahi wai mā te 1.2 miriona litra ia heketeia – ka nui ake te tūmanako o te hua me te māia o te mahi

FAQ

He aha te Coefficient of Uniformity (CU)?

Ko te CU, te Coefficient of Uniformity, tētahi inenga hei whakatau i te āhua ōrite o te toronga wai ki ngā mara e te pūnaha whakawhenua. Ko te tikanga, ko te teitei ake te CU, ko te toronga wai anō te ūrite ake me te mōhiotia ake.

Pēhea te painga a Distribution Uniformity (DU) ki te whakawhenua?

Ko te Distribution Uniformity (DU) te inenga i te āhua ūrite o te toronga wai ki te mara, e pa ana ki te hua o te tipu me te whakamahi rāwekenga. Ko te DU teitei ake, ko te iti ake te hiahia ki te whakawhenua nui, ka tiakina te wai me ngā utu.

He aha te take o te whakahaere i te tokiwa i ngā pūnaha whakawhenua?

He mea nui te whakahaere pēhanga nā te āhua o ngā karu wai me te ū-ā-tiriti o te tukatuka wai. Ka aukati ngā tautuhinga pēhanga tika i te ngaro wai mā te whakaputangia, ka tiakina hoki te kauwhiringa o te oneone.

Me pēhea te whakanui ake i te maruamonenga o te Iwob-2 Sprinkler i ngā takotoranga hau?

Ko te Iwob-2 Sprinkler e pupuri ana i te ū-ā-tiriti o te tukatuka i ngā hau e 3 m/s pea, engari anō te hoahoa karuiti iti me te whakamahi pēhanga iti, ka iti ai te tawhiti o te hau me ngā wāhi kore i te tukatuka.

He aha ngā painga utu o te whakamahi i te Iwob-2 Sprinkler?

Kaitekau e $11–$17 ia heketea ia tau ngā kaiwhakatuu e whakamahi nei i te Iwob-2 Sprinkler, ā, ka penapena rātou i te wai e te 24% atu i ngā pūnaha tawhito, ka pai ake te rerekenga o te hua me te maruamonenga o te mahi.
