Ukutyala ngehydroponics kwenza iprojekthi yeshishini yesikolo elungileyo ngokungaqhelekanga kuba umjikelo wonke ungena kwikota enye. Kwiiveki ezimalunga nezintandathu ukuya kwezisibhozo, iklasi inokusuka kwimbewu ehlumileyo iye kwitroli yemifuno emitsha ethengiswa ngomhla wemarike okanye kumboniso wokuphela konyaka. Esi sikhokelo sihamba nalo mjikelo njengeshishini elincinci lokwenene: ukukhetha izityalo ezigqiba ngexesha, ukubala iindleko zezinto ezifakwayo, ukumisela ixabiso elinokuthethelelwa, ukuthengisa ngaloo mini, kunye nokufumana ukufunda okuninzi kwibhetshi ephela ingaphumelelanga.

Kutheni ukutyala ngehydroponics kusebenza njengeprojekthi yeshishini

Amashishini amaninzi enziwa eklasini angumlingiselelo nje. Ukutyala ngehydroponics akunjalo. Amanzi okwenene, izondlo zokwenene, umbane wokwenene nezityalo zokwenene kuguqulwa kube yimveliso ehlawulelwa ngabantu bokwenene. Umjikelo mfutshane ngokwaneleyo ukuba ugqitywe ngaphakathi kwekota, indawo oyifunayo incinci ngokwaneleyo ukuba ingene ekoneni yeklasi, kwaye yonke into efakwayo iyalinganiseka. Linqaku lokugqibela elenza le nto ifundiseke. Imbewu, umhlaba wokutyala, isisombululo sezondlo kunye nombane zonke zineendleko, ngoko ke abafundi bagqiba ikota bephethe iphepha lenzuzo nelahleko abazenzele lona. Ihamba ngokwemvelo ecaleni kwezibalo, isayensi nokubhala ikhowudi abasele bekwenza kwinkqubo yokubhala ikhowudi neyerobhothiki.

Khetha izityalo ezigqiba ngaphakathi kwekota

Ithuba leeveki ezintandathu ukuya kwezisibhozo lelona nqumo linzima. Likhupha izityalo ezivelisa iziqhamo. Iitumato, oopelepele neestrobheri zithatha iinyanga kwaye ziya kube zisathuma ngomhla wemarike. Endaweni yoko, khetha izityalo zamagqabi ezikhawulezayo, uze utyale iklasi yonke kwiveki enye ukuze isivuno sifike kunye.

• Iletisi yamagqabi akhululekileyo: iyaxolela, ikhawuleza, ithengiswa ngengxowa.
• Irokhethi namagqabi emastade: akhawuleza kwaye anencasa ebukhali, athandwa ngabazali.
• Ibhasil, ikoriyanda kunye nomente: izinongo zifumana imali eninzi ngegram kuneletisi.
• Isipinatshi kunye nepak choi: zithembekile kwaye ziqhelekile kubathengi.

Nanku umbandela wexesha. Ukutyala ngoSeptemba ulindele ukuthengisa ngoNovemba kubeka isivuno sakho ekupheleni kwentwasahlobo, xa ubushushu neentsuku ezinde zityhala izityalo zamagqabi ukuba zikhawuleze ziye embewini, oko kuthetha ukuba ziyaphuncuka ziye embewini zize zibe krakra. Khetha iindidi ezimelana nobushushu, ugcine amanzi epholile, uze uvune kwangethuba kunokuba uvune emva kwexesha.

Zibale iindleko njengeshishini lokwenene

Yahlula iindleko zakho zibe ziimfumba ezimbini. Ukusekwa okwenziwa kanye kuhlawulwa kube kanye kuze kusetyenziswe kwakhona kuwo wonke umjikelo: itanki lamanzi, impompo, iikomityi zeneti, izibambi zomhlaba wokutyala, kunye nezibane zokukhulisa okanye ifestile ejonge emantla efumana ilanga. Izinto ezisetyenziswayo ngamjikelo zithengwa kuyo yonke ibhetshi: imbewu, umhlaba wokutyala, isisombululo sezondlo nombane. Yimfumba yesibini kuphela efanele ukungena kwixabiso lemifuno yale kota. Ukusekwa yinkunzi.

Zimbini izinto zokwenene zoMzantsi Afrika ezifanele ukungena kuhlahlo lwabiwo-mali. Okokuqala, umbane wempompo encinci utshiphu kodwa awusimahla, ngoko ke wulinganise. Okwesibini, ucimicimi luya kuyimisa impompo iiyure ezininzi, kwaye impompo emileyo kwimozulu efudumeleyo inokukubiza isivuno sonke. Mhlawumbi yongeza ibhetri encinci yokugcina, okanye usebenzise uhlobo lweKratky olungasebenzisi mpompo kwaphela. Abafundi abafuna umngeni wokwenza izinto zizenzekele banokubeka impompo kwithaymara baze barekhode umgangatho wamanzi ngemicrocontroller efana nebhodi ye-sheenbot∞, into eyenza ukuba ukutyala kube yiprojekthi yokubhala ikhowudi kwanjengoko kuyiprojekthi yeshishini.

• Imbewu: irandi enye okanye ezimbini kwisityalo ngasinye, idla ngokuba ngaphantsi xa uthenga ngobuninzi.
• Umhlaba wokutyala: i-coco coir, i-rockwool okanye amatye odongwe, inxalenye yawo inokuphinda isetyenziswe.
• Isisombululo sezondlo: yeyona ndleko inkulu ephindaphindayo, ngoko ke silinganise ngokuchanekileyo endaweni yokuqikelela ngamehlo.
• Umbane: mncinci, kodwa ukhona, kwaye ufanele ubhalwe phantsi ukuze i-P&L ibe nyanisekile.

Misela ixabiso eligubungela iindleko nemeko yokwenene

Qala ngendlela yeendleko kunye nenzuzo. Dibanisa zonke izinto ezisetyenziswayo ngamjikelo, wahlule ngenani lezityalo olindele ukuzithengisa ngokwenene kunenani olityalileyo, kuba ezinye ziya kutshabalala, kwaye leyo yindleko yesityalo ngasinye. Yongeza umyinge wenzuzo phezulu. Emva koko qhathanisa nevenkile: libiza malini ingxowa yamagqabi esaladi okanye isithungu sezinongo kwisuphamakethi ekufuphi? Beka ixabiso elikufuphi nelo okanye elingaphantsi kancinci, uze uxhomekeke kwinzuzo yakho enye yokwenene, ekukuba imifuno yakho ichetywe kwangayo loo ntsasa. Ukuthengisa ngengxowa okanye ngesithungu kulula kunokuthengisa ngobunzima, kwaye ukuthatha ii-odolo kwangaphambili kubazali kwiveki edlulileyo kunciphisa ilahleko kwaye kuqinisekisa ingeniso ethile.

Yithengise ngomhla wemarike

Ikota yesine izele yimibhiyozo nemihla yemarike, ngoko ke ikhalenda ikwicala lakho. Yiphathe itroli njengenxalenye yemveliso.

1. Vuna kusasa ngomhla womsitho, uze ugcine imifuno ipholile kwaye ufefe amanzi ambalwa kuyo.
2. Yifake ezingxoweni okanye uyibophe ibe zizithungu ngendlela ecocekileyo, unelebhile elula echaza isityalo neklasi eyakhulisayo.
3. Beka isixhobo sokutyala etafileni. Impompo, ipeni ye-pH nencwadi yeerekhodi zitsala abantu, kwaye ibali lithengisa ngokulinganayo nemveliso.
4. Gcina imali yokutshintsha kwaye, ukuba unako, ube nendlela yokwamkela ikhadi okanye i-EFT ekhawulezayo.

Xa isivuno singaphumeleli, kwaye kunokwenzeka

Inxalenye yebhetshi iya kutshabalala, kwaye ngenye ikota kungenzeka kutshabalale konke. Ukubola kweengcambu, i-algae kwitanki elicacileyo, ukutshintsha kwe-pH, izinambuzane ii-aphid, ukutsha kwezityalo ngenxa yezondlo ezigqithisileyo, okanye impompo efe ngexesha locimicimi, zonke zizinto eziqhelekileyo zokungaphumeleli ezinezizathu eziqhelekileyo. Ukungaphumeleli asiyoprojekthi eyoyisakeleyo. Yidatha. Hlalisa iklasi phantsi niyisebenze njengophando: yintoni etshintshileyo, silinganise ntoni, kwaye yeyiphi into enye esiya kuyilawula ngexesha elizayo. Loo mjikelo weengcinga zophando, wokungaphumeleli nowokuphinda uzame yiyo kanye ikharityhulam. Imifuno yayisoloko iyisizathu nje sokuqhuba lo msebenzi.

Isifundo esiphambili

Imveliso ngumphumela ongongezelelweyo. Into abahamba nayo abafundi lubalo lweendleko abalwakhileyo, ixabiso abalithethelele kumthengi wokwenene, kwaye, kwiminyaka emihle kakhulu, ukungaphumeleli abakuxilongileyo bakulungisa. Eso sisifundo seshishini esinamandla ngaphezu kwawo nawuphi na umlingiselelo, kwaye singena kwikota enye. Ukuba ufuna uncedo lokuqhuba enye, iiworkshop zeeholide zethu ziyindawo elungileyo yokuba iklasi yakhe isixhobo esizenzekelayo nesityalo kunye, kwaye kukho okungakumbi ngeSTEM esekelwe kwiiprojekthi kwigumbi leendaba.

Yeyiphi eyona ndlela itshiphu yokuqala?

Ukusetwa kweKratky okungasebenzisi mpompo kwibhakethi okanye kwithanki yokugcina. Akukho mpompo, akukho mbane, kwaye akukho mngcipheko wocimicimi. Ikhulisa imifuno yamagqabi kakuhle kwaye ngowona mjikelo wokuqala ukhuselekileyo kwiklasi enohlahlo lwabiwo-mali oluncinci.

Zingaphi izityalo ekufuneka itroli yeklasi izikhulise?

Isixhobo esineekomityi zeneti ezingamashumi amabini ukuya kumashumi amane sanele kakhulu kumhla wokuqala wemarike. Sivelisa okwaneleyo ukuze kuthengiswe ngaphandle kokuxakekisa abafundi kwinqanaba lokuvuna nelokupakisha, kwaye sigcina iindleko zezondlo nezokuseka zisezantsi.
