"Imigaqo yobuGcisa yokuDityaniswa kwaManzi kunye nezichumiso kwiZiko lokuLima iMelon" isekelwe kwibhetshi yesibini yeeprojekthi zesicwangciso somgangatho wengingqi woLawulo lweMarike yePhondo yaseShaanxi ngo-2019 "iMimiselo yobuGcisa yaManzi kunye noDityaniso lwesichumiso kwiZiko lokuLima iMelon" (iprojekthi inombolo: SDBXM-135-2019), ngu Weinan Yaqulunqwa ngokudibeneyo nguMasipala Institute of Agricultural Sciences, Pucheng County Agricultural Technology Promotion Centre, kunye Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative.
Iqela lokufundisa kunye neqela lophando lokulima indawo yokulawula umhlaba-isichumiso-amanzi kwiSikolo seZibonelelo kunye nokusiNgqongileyo, iYunivesithi yaseMntla-ntshona ye-A&F iye yabandakanyeka kuphando lokuchuma komhlaba, ukuchumisa kunye namanzi kunye nokuhlanganiswa kwesichumisi sendawo yokulima imifuno ixesha elide.Ukususela kwi-2016 ukuya kwi-2018, idibanise inkqubo yekhosi kunye neprojekthi yesizwe ephambili yophando kunye nesicwangciso sophuhliso "eNtshonalanga Uphando kunye nophuhliso lwetekhnoloji ephambili yokunciphisa ukusetyenziswa kwezichumisi zekhemikhali kunye nezibulala-zinambuzane kwiimelon kunye nobuchwepheshe obuphambili" uphando ngemeko yangoku yokuchumisa nokunkcenkceshela. yeemelon phantsi kolimo kwiPhondo laseShaanxi kwiSithili saseYanliang, kwiNqila yasePucheng, nakwiNqila yaseFuping, eyona ndawo ivelisa imelon ephambili kwiPhondo laseShaanxi.Iingxaki zokuchumisa okugqithisileyo kunye nokunkcenkceshela zivelele e-China (iphepha elipapashiweyo: Guo Yawen et al., 2020, Journal of Plant Nutrition and Fertilizers), ibonakaliswe ngokukodwa ukuba ukuphindaphinda kunye nesixa sokunkcenkceshela phantsi kwemeko yamanzi kunye nokuhlanganiswa kwezichumiso. zifana okanye ziphezulu kunezo zokunkcenkceshela kunye nokunkcenkceshela imisele, kunye nokunkcenkceshela okonga amanzi Isiphumo sesixhobo siphantsi.Umlinganiselo wezondlo zokusetyenziswa kwe-basal yezichumisi zeekhemikhali ziphezulu kakhulu, kwaye umlinganiselo wamanzi adibeneyo kunye ne-topdressing yesichumisi sincinci.Ukukhethwa kwezichumisi akuhambelani nenzululwazi.Amafama ikakhulu athembele kwipropaganda yeshishini ekukhetheni izichumisi, kwaye igalelo lezondlo alilingani.
Ngokusekwe kwezi ngxaki zingentla, iYunivesithi yaseMntla-ntshona yezoLimo kunye nezamaHlathi, iZiko loPhando lweNzululwazi yezoLimo i-Weinan, iZiko lokuKhuthaza iTekhnoloji yezoLimo ePucheng County, kunye neYangling Dongfang Qianpu Manor Agricultural Professional Cooperative yafaka isicelo kwi-Bureau yePhondo yaseShaanxi yoLawulo lobuGcisa ukuze kuqulunqwe “iTekhnoloji yoManyano lwaManzi. kunye neSichumisi seZiko lokuLima iMelon” Regulations, eyavunywa ngo-2019. Lo mgangatho wasekhaya usekwe kuphononongo olucwangcisiweyo lwesondlo, iimpawu zemfuno yamanzi, kunye nesiqulatho sokufuma komhlaba esifanelekileyo sevatala kumanqanaba ahlukeneyo okukhula, ukunika umdlalo opheleleyo iingenelo zamanzi adibeneyo kunye nesichumiso sokuchumisa kunye nenkqubo yokunkcenkceshela, kunye nokuqulunqa umlinganiselo, ubuninzi, i-quota yokunkcenkceshela, kunye nenkqubo yokunkcenkceshela yokusetyenziswa kwezondlo kwizigaba ezahlukeneyo zokukhula kweemelon.Ixesha, kunye neteknoloji yolawulo oluchanekileyo oludibeneyo lwamanzi kunye nesichumisi esifana nokuchumisa kunye ne-quota yokunkcenkceshela phantsi komgangatho wemveliso ekujoliswe kuyo yezibonelelo ze-melon e-Shaanxi.Ubuchwephesha buye baziwa kwaye basetyenziswa kwimimandla emininzi, kwaye inani elipheleleyo le-nitrogen, i-phosphorus kunye ne-potassium yokusetyenziswa kwezichumisi ze-melon iye yancitshiswa nge-65%, i-84% kunye ne-68% xa kuthelekiswa nokuchumisa okuqhelekileyo.Amanzi e-backwater fertilizer aphathwa ngezixhobo ze-ultraviolet sterilization ukuthintela ngokufanelekileyo ibhaktheriya kumzimba wamanzi wesityalo.Umngundo uyakhula kwaye izityalo zikhula ngokuchumileyo.Xa kuthelekiswa nemigangatho efanayo, ihambelana ngakumbi nemeko yokuveliswa kwemveliso e-Shaanxi, enomxholo opheleleyo wezobugcisa, iiparitha ezicacileyo zesalathisi, kunye nokusebenza okulula kunye nokuphunyezwa.
