Hoʻohui i ka wai a me nā mea momona

Hoʻokumu ʻia ka "Regulatory Technical Regulation for Water and Fertilizer Integration of Facility Cultivation of Melon" ma ka papa ʻelua o nā papahana hoʻolālā hoʻolālā kūloko kūloko o Shaanxi Provincial Market Supervision Administration in 2019 "Technical Regulations for Water and Fertilizer Integration of Facility Cultivation of Melon" (project. helu: SDBXM-135-2019), na Weinan Ua hui pū ʻia e ka Municipal Institute of Agricultural Sciences, Pucheng County Agricultural Technology Promotion Center, a me Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative.

ʻO ke aʻo ʻana a me ka hui noiʻi o ka hoʻokele waiwai o ka lepo-fertilizer-wai ma ke kula o nā kumu waiwai a me ke kaiapuni, Northwest A&F University ua hana i ka noiʻi e pili ana i ka momona o ka lepo, fertilization a me ka wai a me ka hoʻohui ʻana o nā mea kanu hale no ka manawa lōʻihi. Mai 2016 a 2018, ua hui pū ʻia ka hana papa a me ka papahana noiʻi nui a me ka hoʻolālā hoʻomohala ʻāina "Western ʻO ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana koʻikoʻi no ka hoʻohaʻahaʻa ʻana i ka noi ʻana o nā mea kanu kemika a me nā pesticides no nā melons a me nā ʻenehana koʻikoʻi" i noiʻi i ke kūlana o ka fertilization a me ka irrigation. ʻO nā melons ma lalo o ka mahiʻai ʻana ma Shaanxi Province ma Yanliang District, Pucheng County, a me Fuping County, nā wahi hana melon nui o Shaanxi Province. ʻO nā pilikia o ka hoʻoulu ʻana a me ka hoʻoulu ʻana he mea koʻikoʻi ia ma Kina (ka pepa i paʻi ʻia: Guo Yawen et al., 2020, Journal of Plant Nutrition and Fertilizers), i hōʻike nui ʻia i ka pinepine a me ka nui o ka irrigation ma lalo o ke ʻano o ka wai a me ka hoʻohui ʻana i nā mea kanu. like a i ʻole ʻoi aku ka kiʻekiʻe ma mua o ka wai o ka wai a me ka wai irrigation, a me ka wai hoʻōla wai He haʻahaʻa ka hopena o ka mīkini. ʻOi aku ka kiʻekiʻe o ka nutrient ratio o ka noi basal o nā mea kanu kemika, a he liʻiliʻi ka hapa o ka wai hoʻohui a me ka topdressing fertilizer. ʻAʻole ʻepekema ke koho ʻana i nā mea kanu. Ke hilinaʻi nui nei ka poʻe mahiʻai i ka hoʻolaha pāʻoihana no ke koho ʻana i nā mea kanu, a ʻaʻole kaulike ka hoʻokomo ʻana i nā meaʻai.

Ma muli o nā pilikia i luna, Northwest Agriculture and Forestry University, Weinan Agricultural Science Research Institute, Pucheng County Agricultural Technology Promotion Center, a me Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative i noi i ka Shaanxi Provincial Bureau of Technical Supervision e hoʻokumu i ka "Integration Technology of Water. a me Fertilizer for Facility Cultivation of Melon" Regulations, i apono 'ia ma 2019. Ho'okumu 'ia keia ma'amau kūloko ma ka ho'ona'auao 'ōnaehana o ka mea kanu, nā 'ano koi wai, a me ka ma'ama o ka lepo kūpono o nā melons i nā pae ulu like 'ole, e hā'awi ana i ka pā'ani piha i ka. nā pono o ka wai i hoʻohui ʻia a me ka mea hoʻomomona a me ka ʻōnaehana irrigation, a me ka hoʻokumu ʻana i ka lakio, ka nui, irrigation quota, a me ka ʻōnaehana irrigation o ka noi nutrient i nā pae ulu like ʻole o nā melons. ʻO ka wā, a me ka ʻenehana hoʻokele pololei i hoʻohui ʻia o ka wai a me ka mea hoʻomomona e like me ka fertilization a me ka irrigation quota ma lalo o ke kiʻekiʻe o nā huahana melon ma Shaanxi. Ua hoʻolaha ʻia ka ʻenehana a hoʻohana ʻia i nā wahi he nui, a ua hoʻemi ʻia ka nui o ka nitrogen, phosphorus a me ka pālolo pālolo o nā melon fertilizers e 65%, 84% a me 68% i hoʻohālikelike ʻia me ka fertilization maʻamau. Hoʻomaʻamaʻa ʻia ka wai fertilizer backwater me nā keʻena sterilization ultraviolet e pale pono i ka bacteria i loko o ke kino wai mea kanu. Piʻi ka poʻo a ulu nui nā mea kanu. Ke hoʻohālikelike ʻia me nā kūlana like, ʻoi aku ia ma ka laina me ke kūlana hana maoli ma Shaanxi, me ka ʻike ʻenehana piha, nā ʻāpana kuhikuhi kikoʻī, a me ka hana maʻalahi a me ka hoʻokō.
