Ochwepheshe abagunyaziwe bayavuma ukuthi iuhlelo lokunisela oluhlakaniphileisofthiwe nesilawuli singalondoloza imithombo yamanzi ngaphansi kwezimo ezihlukahlukene uma kuqhathaniswa nezilawuli zokunisela zendabuko. Ezinye izifundo zokuqhathanisa zibonise ukuthi ukonga amanzi kungafinyelela ku-30% kuya ku-50%. Ukuhlolwa okwenziwa yi-Irrigation Research Institute (IA, Rice University International Water Research Centre, California, USA) kubonisa ukuthi izilawuli zokunisela ezihlakaniphile zingonga amanzi angaphezu kuka-20% kunezilawuli zokunisela zendabuko.

Olunye ucwaningo lwesayensi luhlole isilawuli sesibonelo/isofthiwe yesistimu yokwamukela isignali. I-suhleloisoftware iqukethe isilawuli sokunisela sendabuko. Isilawuli siyamukeleka ngemva kokulungiswa. Ukonga amanzi kwangaphandle kusekelwe kwimfuneko yeminyaka emi-2 yangaphambi kokufakwa. Kukalwa futhi kulungiswe ngokuvumelana nezimo zezulu. Isilinganiso sokulondolozwa kwangaphandle okubikiwe singu-16%, okubikwa ukuthi silingana no-85% wokonga okungaba khona ngokusekelwe kunkomba engu-ET.

Umthelela wesilawuli sokunisela esihlakaniphile sezolimo ekongeni amanzi

Senze ucwaningo lwesayensi lokonga amanzi oluhlobene nozakwethu bonga amanzi, okuwumfelandawonye wemishini engama-24 yokuphakela ugesi. Ukonga amanzi kubalwa ngokusekelwe ekusetshenzisweni kwesikhathi esingokomlando, futhi ukulungiswa kwenziwe ezimeni zesimo sezulu. Ngokwemibiko, kumasayithi asebenzisa izilawuli zezinzwa, isayithi ngalinye elisebenzisa izilawuli zezinzwa zemvula zonga amathani angu-20,73 ngonyaka, futhi isayithi ngalinye lilondoloza amathani angu-100 ngonyaka.

Ngokuphathelene nokuqonda, uhlelo lokulawula ukuchelela okuzenzakalelayo lungonga amanzi futhi luyonga kakhulu kunezindlela zokunisela zendabuko. Igcina izinsiza eziningi kanye nezindleko ezingeni elithile. Ngakho-ke, kuyadingeka ukuthenga izilawuli zokunisela ezonga amanzi zokulima nokunisela izilwane. Umkhiqizo unamandla futhi ikhwalithi iqinisekisiwe!

Ukutshala imifino ezindaweni zokugcina izithombo zelanga kuyindlela eyinhloko yokukhulisa imali kubalimi bemifino, ngezindleko eziphansi kanye nomphumela ophezulu. Ngesikhathi esifanayo, kuwumkhuba wokuthuthukiswa kwemifino engangcolisi. Ngenxa yokukhula okuqhubekayo konyaka wokunisela okuhlakaniphile, isifo se-nematode sezimpande, ukubola kwezimpande, i-fusarium wilt nezinye izifo endaweni ebamba ukushisa kwelanga kanye nokufakwa kukasawoti enhlabathini kubi kakhulu, okuthinta ukwanda kokukhiqizwa kwemifino kanye nemali engenayo. Ukugqugquzelwa kokutshalwa kwenhlabathi ngaphandle kwenhlabathi, i-straw bioreactor kanye nezifo kanye nobuchwepheshe bokulawula izinambuzane kuzuze imiphumela yezomnotho, yezenhlalo kanye nemvelo.

1. Ukungenisa umoya ophahleni: Kwamukelwa ifekthri yemifino yokukhanya kwelanga, futhi kwamukelwa indlela yefasitela elintengantengayo elimise okwevemvane.

2. Ukungenisa komoya oseceleni: Faka amafasitela ephaneli enziwe ngepulasitiki akhishwe ngaphandle angu-60mm empumalanga nasentshonalanga ye-Sunlight Vegetable Factory endaweni ephakeme cishe ngo-0.6m ukusuka phansi, ukuphakama kwefasitela kungu-1.2m;

3. Ukwakheka kwe-Sunlight Vegetable Factory; Izici zemishini yokushisisa kanye nemishini yokupholisa umehluko wamazinga okushisa, izinga le-Intanethi Yezinto Yezolimo kanye nokuhlushwa kwe-carbon dioxide phakathi kwezindawo ezahlukene zemikhiqizo yemifino ye-Sunlight, kanye nezinga lokushisa lomoya endaweni ekhulayo isitshalo, ukuze kwenziwe umswakama Futhi ukuhlushwa kwe-carbon dioxide kusatshalaliswa ngokulinganayo, futhi ifeni ingasetshenziswa futhi ukugeleza umoya ngokuzenzakalelayo.

4. Amanethi alwa nezinambuzane: Faka amanethi alwa nezinambuzane anobubanzi obuyi-1.8m ukusuka esweni lama-20 kuye kwelama-32 kuzo zonke izingxenye ezivulayo ukuze uvimbele futhi ulaphe izinambuzane. Izifo ezithathelwanayo kanye nokutshalwa kwenetha kwekhava okuvikela izinambuzane kuwubuchwepheshe bezolimo obusha nobusebenzayo obungayingeni imvelo okwandisa ukukhiqizwa futhi kwakhe imigoqo yokuzenzela yokuzihlukanisa emashalofini. Ngaphandle kwamanetha axosha izinambuzane, nqamula indlela yokuzala yezinambuzane (abadala), kanye nezinambuzane ezinhlobonhlobo, ngokwesibonelo, zingamacimbi, imifino, izimpukane nama-aphid ngempumelelo. Inezingozi zokuvimbela ukusakazeka kwe-jumping beetles, i-beet armyworm, i-Liriomyza sativae, ne-Spodoptera litura, kanye nokudluliselwa kwezifo ezibangelwa amagciwane, futhi inemisebenzi yokudlulisela ukukhanya, ukuthungatha okuphakathi, kanye nokukhipha umoya. Inezimo ezivumayo zokudala ukukhula kwezitshalo ezifanele. Inciphisa ukusetshenziswa kwezibulala-zinambuzane zamakhemikhali emasimini emifino, futhi inikeza ubuchwepheshe obunamandla bokukhiqiza imikhiqizo yezolimo eluhlaza engangcoliswanga ukuze kukhiqizwe izitshalo ezisezingeni eliphezulu, ezihlanzekile nezikhiqizayo.

Ngokuthuthukiswa kolwazi kanye nokwenza ngcono ezolimo, ubuchwepheshe be-inthanethi Yezinto buhlanganiswe ngokugcwele nemboni yezolimo. Imishini ye-inthanethi Yezinto ibamba iqhaza ohlelweni lokulawula oluzenzakalelayo ngokusebenzisa amathuluzi ahlukahlukene kanye nemishini, futhi inikeza isisekelo sesayensi sokulawula igeji yokucindezela + i-valve yebhola + ikhophi yesilawuli.png ukuze kube nomphumela obamba ukushisa. Ngokusekelwe kulokhu, kwazalwa indlu ehlakaniphile. Kuphi "ukuhlakanipha" kwe-plastic greenhouse? 1. Isistimu yenethiwekhi ye-inthanethi Yezinto, okokusebenza kokulawula okuzenzakalelayo, isistimu yokuchelela ezenzakalelayo ye-Zhejiang inodi yokuqoqa esebenzayo, inzwa yokushisa, inzwa yomswakama,ukuchelela okuhlakaniphileInzwa yenani engu-PH, kanye nenzwa yokukhanyisa isethwe ophahleni oluhlakaniphile lokuphatha. Lawa madivayisi afaka amadivayisi afana nezinzwa ze-carbon dioxide angathola imingcele ebonakalayo efana nezinga lokushisa, umswakama ohlobene, i-pH, amandla okukhanya, imisoco yenhlabathi, ukugcwala kwe-carbon dioxide, njll. endaweni ezungezile, futhi ibe nendawo enhle yokutshala izitshalo.

Ngokusetshenziswa kohlelo lwenethiwekhi ye-inthanethi Yezinto, abakhiqizi bangathola ngokushesha izinkinga, futhi bangakwazi ukucacisa ngokunembile indawo yenkinga, futhi babone ukuphathwa okuhlakaniphile kokukhiqizwa kwezolimo. I-greenhouse eyonga amandla ehlakaniphile ifakwe izinto ze-electromechanical ezifana nama-shutter kagesi, abalandeli, ukuchelela ngogesi kanye nezinhlelo zokunisela, futhi ibona umsebenzi wokulawula kude. Abakhiqizi bangangena ohlelweni ngomakhalekhukhwini noma ikhompuyutha yomuntu siqu, futhi bangakwazi ukulawula i-valve yamanzi ku-greenhouse, isiphephetha-moya sesisombululo sokuchelela esihlakaniphile, kanye nokushintshwa kwekhethini; futhi ingasetha i-logic yokulawula, futhi uhlelo lungavula noma luvale ngokuzenzakalelayo ikhethini, i-valve yamanzi, i-blower, njll ngokusho kwezimo zangaphakathi nezangaphandle ze-Chamber motor. 3. Umbuzo okhaliphile Ngemva kokuba umkhiqizi engene ohlelweni ngomakhalekhukhwini noma ngekhompyutha yomuntu siqu, angabuza yonke imingcele yendawo ezungezile, izinga lokushisa lomlando kanye namajika omswakama, kanye namarekhodi omlando okusebenza kwemishini ye-electromechanical ku-greenhouse ngesikhathi sangempela. Umsebenzi we-alamu wezithombe zomlando ungabhekwa ngesikhathi sangempela. Umkhawulo kanye nomkhawulo ophansi, izinhlobo zezitshalo, umjikelezo wokukhula, futhi uziguqule ukuze usethe amanani okusetha ngokushintsha kwezinkathi zonyaka. Uma idatha ethile yeqa inani elilinganiselwe, isistimu yenethiwekhi ye-inthanethi Yezinto ngokushesha ithumela umlayezo oyisixwayiso kumkhiqizi ohambisanayo, futhi ingaqapha futhi ilandelele izinyathelo ezazisa umdidiyeli ngesikhathi. Ngemva kwezinzwa ezihlukahlukene zokuqapha kanye nezinhlelo zenethiwekhi zokulondoloza yonke idatha yokuqapha, iba umthombo okahle wokulandelela umkhiqizo wokukhiqizwa kwezolimo. Izindlu ezihlakaniphile zingakwazi ukubona umsebenzi wokuqopha umjikelezo wempilo wemikhiqizo yezolimo, okuhlanganisa yonke imikhiqizo yezolimo kusukela esikhathini sokutshala kuya esikhathini sokuvuna.
