Ochwepheshe abanegunya bayavuma ukuthiuhlelo lokunisela oluhlakaniphileisofthiwe kanye nomlawuli kungasindisa izinsiza zamanzi ngaphansi kwezimo ezahlukahlukene uma kuqhathaniswa nabalawuli bokunisela bendabuko. Ezinye izifundo zokuqhathanisa zibonise ukuthi ukonga amanzi kungafinyelela ku-30% kuya ku-50%. Ukuhlolwa okwenziwe yi-Irrigation Research Institute (IA, Rice University International Water Research Center, eCalifornia, e-USA) kukhombisa ukuthi abalawuli bokunisela abahlakaniphile bangasindisa amanzi angaphezu kuka-20% kunabalawuli bokunisela bendabuko.

Olunye ucwaningo lwesayensi luhlole isofthiwe yesistimu yokulawula/yokwamukela isignali.isistimuisofthiwe iqukethe isilawuli sokunisela sendabuko. Isilawuli siyamukeleka ngemva kokuguqulwa. Ukonga amanzi ngaphandle kusekelwe esidingweni seminyaka emibili ngaphambi kokufakwa. Kulinganiswe futhi kulungiswe ngokwezimo zezulu. Isilinganiso sokonga ngaphandle okubikiwe singama-16%, okubikwa ukuthi silingana nama-85% okonga okungenzeka ngokusekelwe ku-ET ebhekisele kukho.

Umphumela womlawuli wokunisela ohlakaniphile kwezolimo ekongeni amanzi

Senze ucwaningo lwesayensi lokunisela okonga amanzi oluhlobene nabalingani abalondoloza amanzi, oluyinhlanganisela yemishini yokunikeza ugesi engu-24. Ukonga amanzi kubalwa ngokusekelwe ekusetshenzisweni kwesikhathi esidlule, futhi kwenziwe izinguquko ezimweni zezulu. Ngokusho kwemibiko, ezindaweni ezisebenzisa izilawuli zezinzwa, indawo ngayinye esebenzisa izilawuli zezinzwa zemvula isindisa amathani angu-20,73 ngonyaka, kanti indawo ngayinye isindisa amathani ayi-100 ngonyaka.

Ngokuphathelene nobubanzi, uhlelo lokulawula ukuchelela oluhlakaniphile oluzenzakalelayo luyonga amanzi futhi longa izindleko kunezindlela zokuchelela zendabuko. Luyonga izinsiza eziningi nezindleko ezingeni elithile. Ngakho-ke, kubalulekile ukuthenga abalawuli bokuchelela abangonga amanzi bokuchelela kwezolimo nokufuya izilwane. Umkhiqizo unamandla futhi ikhwalithi iyaqinisekiswa!

Ukutshala imifino ezindaweni zokugcina izithombo zelanga kuyindlela eyinhloko ekhulisa imali yabalimi bemifino, ngezindleko eziphansi kanye nomphumela ophezulu. Ngesikhathi esifanayo, kuyindlela yokuthuthukiswa kwemifino engenakho ukungcola. Ngenxa yokutshala okuqhubekayo kokunisela ngonyaka, isifo se-root nematode, ukubola kwezimpande, ukubuna kwe-fusarium kanye nezinye izifo endaweni yokugcina izithombo zelanga kanye nosawoti wenhlabathi kubi kakhulu, okuthinta ukwanda kokukhiqizwa kwemifino kanye nemali engenayo. Ukukhuthazwa kokutshala inhlabathi ngaphandle kwesistimu yezemvelo, i-straw bioreactor kanye nobuchwepheshe bokulawula izifo kanye nezinambuzane kufinyelele imiphumela yezomnotho, yezenhlalo neyemvelo.

1. Umoya wokungenisa umoya ophahleni: Ifektri yemifino ekhanyiswe yilanga iyasetshenziswa, bese kusetshenziswa indlela yefasitela elinomfanekiso webhathane elinophahla.

2. Umoya ophuma eceleni: Faka amafasitela ephaneli ehlanganisiwe epulasitiki angu-60mm ezinhlangothini ezisempumalanga nasentshonalanga ze-Sunlight Vegetable Factory endaweni ephakeme cishe ngamamitha angu-0.6 ukusuka phansi, ukuphakama kwefasitela kungu-1.2m;

3. Isakhiwo se-Sunlight Vegetable Factory; izici zemishini yokushisa kanye nemishini yokupholisa umehluko ekushiseni, izinga le-Internet of Things yezolimo kanye nokuhlushwa kwe-carbon dioxide phakathi kwezindawo ezahlukene zemikhiqizo yemifino ye-Sunlight, kanye nokushisa komoya endaweni ekhulayo yesitshalo, ukuze kwenziwe umswakama kanye nokuhlushwa kwe-carbon dioxide kusatshalaliswa ngokulinganayo, futhi ifeni ingasetshenziswa futhi ukugeleza umoya ngokwenziwa.

4. Amanethi okulwa nezinambuzane: Faka amanethi okulwa nezinambuzane anobubanzi obungu-1.8m kusukela esweni lama-20 kuya kwelama-32 kuzo zonke izingxenye zokuvula ukuze uvimbele futhi welaphe izinambuzane eziyingozi. Izifo ezithathelwanayo kanye nokutshalwa kwesembozo senethi esingavimbeli izinambuzane ubuchwepheshe bezolimo obusha nobusebenzayo obunobungani nemvelo okwandisa ukukhiqizwa futhi bakhe izithiyo zokuhlukanisa ezenziwe ngama-detached emashalofini. Ngaphandle kwamanethi axosha izinambuzane, anquma indlela yokuzalana kwezinambuzane (abantu abadala), kanti izinambuzane ezahlukahlukene, isibonelo, ziyasebenza. Lawula izibungu, imifino, izimpukane ezimhlophe, kanye nama-aphid. Inezingozi zokuvimbela ukudluliswa kwezimbungulu ezigxumayo, i-beet armyworm, i-Liriomyza sativae, kanye ne-Spodoptera litura, kanye nokudluliswa kwezifo ezibangelwa amagciwane, futhi inemisebenzi yokudlulisa ukukhanya, ukufiphaza okulinganiselwe, kanye nokungenisa umoya. Inezimo ezinhle zokudala ukukhula kwezitshalo ezifanele. Inciphisa ukusetshenziswa kwezibulala-zinambuzane zamakhemikhali emasimini emifino, futhi inikeza ubuchwepheshe obunamandla bokukhiqiza imikhiqizo yezolimo eluhlaza engenakungcola ukuze kukhiqizwe izitshalo ezisezingeni eliphezulu, ezihlanzekile nezikhiqizayo.

Ngokuthuthuka kolwazi kanye nokuthuthukiswa kwezolimo, ubuchwepheshe be-Intanethi yezinto buhlanganiswe ngokugcwele nomkhakha wezolimo. Imishini ye-Intanethi yezinto ihlanganyela ohlelweni lokulawula oluzenzakalelayo ngamathuluzi nemishini eyahlukahlukene, futhi inikeza isisekelo sesayensi sokulawula i-pressure gauge + i-ball valve + i-controller copy.png yomphumela we-greenhouse. Ngokusekelwe kulokhu, kwazalwa indlu ehlakaniphile. Kuphi "ukuhlakanipha" kwe-greenhouse yepulasitiki? 1. Uhlelo lwenethiwekhi ye-Intanethi yezinto, imishini yokulawula okuzenzakalelayo, uhlelo lokunisela oluzenzakalelayo lwe-Zhejiang olunemisebenzi eminingi, inzwa yokushisa, inzwa yomswakama,ukunisela okuhlakaniphileInzwa yenani le-PH, kanye nenzwa yokukhanyisa ebekwe ophahleni oluhlakaniphile lokuphatha. Lawa madivayisi afaka phakathi amadivayisi afana nezinzwa ze-carbon dioxide angathola imingcele ebonakalayo njengokushisa, umswakama ohlobene, i-pH, ukuqina kokukhanya, izakhamzimba zomhlabathi, ukuhlushwa kwe-carbon dioxide, njll. endaweni ezungezile, futhi abe nendawo enhle yokutshala izitshalo.

Ngokusebenzisa uhlelo lwenethiwekhi ye-Inthanethi yezinto, abakhiqizi bangathola izinkinga ngokushesha, futhi banganquma ngokunembile indawo yenkinga, futhi baqaphele ukuphathwa okuhlakaniphile komkhiqizo wezolimo. Indlu ehlakaniphile yokonga amandla ifakwe imishini ye-electromechanical efana nama-shutter kagesi, amafeni, izinhlelo zokunisela zikagesi kanye nokunisela, futhi iqaphela umsebenzi wokulawula okude. Abakhiqizi bangangena ohlelweni ngocingo oluphathwayo noma ngekhompyutha yomuntu siqu, futhi bangalawula i-valve yamanzi ku-greenhouse, ifeni yesisombululo sokunisela esihlakaniphile, kanye neswishi yekhethini; futhi bangabeka i-logic yokulawula, futhi uhlelo lungavula noma luvale ngokuzenzakalelayo ikhethini, i-valve yamanzi, i-blower, njll. ngokwezimo zangaphakathi nezangaphandle Imoto yegumbi. 3. Umbuzo ohlakaniphile Ngemva kokuba umkhiqizi engene ohlelweni ngocingo oluphathwayo noma ngekhompyutha yomuntu siqu, angabuza yonke imingcele yemvelo, amazinga okushisa omlando kanye nomswakama, kanye namarekhodi okusebenza kwemishini ye-electromechanical yomlando ku-greenhouse ngesikhathi sangempela. Umsebenzi we-alamu wezithombe zomlando ungahlolwa ngesikhathi sangempela. Umkhawulo kanye nomkhawulo ophansi, izinhlobo zezitshalo, umjikelezo wokukhula, futhi uzishintshe ukuze usethe amanani okusetha ngokuya ngezinguquko zezinkathi zonyaka. Uma idatha ethile idlula inani elinqunyelwe, uhlelo lwenethiwekhi ye-Inthanethi yezinto luthumela ngokushesha umlayezo wesexwayiso kumkhiqizi ofanele, futhi lungaqapha futhi lulandelele izinyathelo ezikwazisa umkhiqizi ngesikhathi. Ngemva kokuba izinzwa ezahlukene zokuqapha kanye nezinhlelo zenethiwekhi zigcine yonke idatha yokuqapha, iba umthombo olula wokulandelela umkhiqizo wokukhiqiza kwezolimo. Izindlu ezihlakaniphile zingaqaphela umsebenzi wokuqopha umjikelezo wokuphila kwemikhiqizo yezolimo, kufaka phakathi yonke imikhiqizo yezolimo kusukela esikhathini sokutshala kuya esikhathini sokuvuna.
