Ko te "Rekureihana Hangarau mo te Wai me te Wairakau Whakakotahitanga mo te Whakawhanaketanga o te Merengi" kei runga i te roopu tuarua o nga kaupapa mahere whakatakotoranga paerewa a-rohe o Shaanxi Provincial Market Supervision Administration in 2019 "Rekureihana Hangarau mo te Wai me te Wairakau Whakauru mo te Maara Rawa o Melon" (kaupapa nama: SDBXM-135-2019), na Weinan I hangaia tahi e te Municipal Institute of Agricultural Pūtaiao, Pucheng County Agricultural Technology Promotion Centre, and Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative.
Ko te roopu whakaako me te roopu rangahau o te maara whakaurunga oneone- tongi-te whakahaere wai i te Kura o nga Rauemi me te Taiao, Te Whare Wananga o Northwest A&F kua mahi rangahau mo te hua o te oneone, te whakakikiritanga me te wai me te whakauru tongi o nga huawhenua whakato whare mo te wa roa. Mai i te tau 2016 ki te 2018, ka whakakotahihia e ia nga mahi akoranga me te kaupapa rangahau matua me te kaupapa mahere whanaketanga a-motu "Te Tai Hauauru Ko te rangahau me te whakawhanaketanga o nga hangarau matua mo te whakaiti i te whakamahinga o nga maniua matū me nga pesticides mo nga merengi me nga hangarau matua" i tirotirohia te ahuatanga o naianei mo te whakakikiritanga me te irrigation. o nga merengi i raro i te maara whare i te Porowini o Shaanxi i te Takiwa o Yanliang, te Kaute o Pucheng, me te Fuping County, te merengi matua whakaputa rohe o Shaanxi Porowini. Ko nga raruraru o te kikiritanga nui me te irrigation he mea nui ki Haina (pepa i whakaputaina: Guo Yawen et al., 2020, Journal of Plant Nutrition and Fertilizers), i te nuinga o te wa e whakaatuhia ana ko te auau me te nui o te irrigation i raro i te ahua o te wai me te whakauru tongi. he rite, he teitei ake ranei i era o te irrigation waipuke me te irrigation moa, me te irrigation whakaora wai He iti te paanga o te taputapu. He nui rawa te ōwehenga matūkai o te tono taketake o nga maniua matū, he iti te wahanga o te wai whakauru me te whakakakahu i te tongi. Ko te kowhiringa o nga maniua he kore matauranga. Ko te nuinga o nga kaiahuwhenua e whakawhirinaki ana ki te whakatairanga pakihi mo te kowhiri tongi, a, kaore i te taurite te whakaurunga matūkai.
I runga i nga raruraru o runga ake nei, ko te Whare Wananga o Te Taitokerau Ahuwhenua me te Ngahere Ngahere, Weinan Agricultural Science Research Institute, Pucheng County Agricultural Technology Promotion Center, me Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative i tono ki te Shaanxi Provincial Bureau of Technical Supervision ki te whakatakoto i te "Integration Technology of Water. me te Fertilizer for Facility Cultivation of Melon” Regulations, i whakamanahia i te tau 2019. Ko tenei paerewa a-rohe e ahu mai ana i runga i te rangahau nahanaha o te nga matūkai, nga ahuatanga o te hiahia wai, me te makuku oneone e tika ana mo nga merengi i nga waahanga tipu rereke, e whakaatu ana i nga painga o te wai whakauru me te tongi whakakikiritanga me te punaha irrigation, me te whakatakoto i te ōwehenga, te rahinga, te motunga irrigation, me te punaha irrigation o matūkai. tono i roto i nga wahanga tipu rereke o te merengi. Wā, me te hangarau whakahaere pū o te wai me te tongi pērā i te kikiritanga me te irrigation motunga i raro i te taumata hua taumata o merengi whakaurunga i Shaanxi. Kua rongonuihia te hangarau me te tono i roto i nga rohe maha, a kua heke te tapeke o te hauota, te ūkuikui me te pāhare pāporo o nga maniua merengi e 65%, 84% me te 68% ki te kikiritanga tikanga. Ko te wai tongi o muri ka tukuna ki nga whakaurunga whakamaoritanga ultraviolet hei aukati i nga huakita i roto i te tinana wai tipu. Ka tipu te maaka, ka tipu ake nga tipu. Ina whakaritea ki nga paerewa rite, he nui ake te ahua o te ahuatanga o te whakaputanga i Shaanxi, me nga mea hangarau katoa, nga tohu tohu tohu maamaa, me te ngawari o te mahi me te whakatinanatanga.
