Ama-greenhouse epulasitiki abe yisinqumo esithandwayo kubalimi nabalimi, ngenxa yezindleko zabo eziphansi kanye nokufaka kalula. Banikeza indlela engabizi kakhulu yokwelula isikhathi sokukhula nokuvikela izitshalo ezimeni zesimo sezulu esibi. Kodwa-ke, ngenkathi izindlu zokugcina izithombo zepulasitiki zibonakala ziyisixazululo esihle, ziza nezinselele ezimbalwa abantu abaningi abangazinaki. Nakhu ukuhlolisisa izindaba okufanele uzicabangele ngaphambi kokutshala imali ku-greenhouse yepulasitiki.
Izindleko: Ingabe Kushibhile Ngempela Njengoba Ucabanga?
Izindlu zokugcina izithombo zepulasitiki zivame ukubonwa njengenye indlela ethengekayo kunengilazi noma i-polycarbonate (PC) zokugcina izithombo. Amamodeli epulasitiki amancane ngokuvamile anentengo ephansi, okuwenza akhange kubantu abazilibazisayo kanye nabalimi abancane bezingadi. Kodwa-ke, izindleko zezindlu zokugcina izithombo zepulasitiki zingahluka kakhulu kuye ngokuthi hlobo luni lwepulasitiki esetshenziswayo kanye nokuqina kwayo. Uma ufuna i-greenhouse ehlala isikhathi eside, uzodinga ukutshala imali kumapulasitiki aqinile, amelana ne-UV, anganyusa izindleko kakhulu. Ukwengeza, njengoba ubukhulu nobunkimbinkimbi be-greenhouse bukhula, kanjalo nentengo, ukunciphisa inzuzo yezindleko zokuqala.
Ukugcina Ukushisa: Ingabe "Zingapheka" Izitshalo Zakho Ngempela Ehlobo?
Izindlu zokugcina izithombo zepulasitiki zinhle kakhulu ekugcineni ukushisa, okuhle kakhulu ezindaweni ezibandayo, kodwa zingabangela izinkinga lapho kushisa. Ezindaweni ezinokushisa okukhulu kwasehlobo, amazinga okushisa ngaphakathi kwendawo ebamba ukushisa yepulasitiki angadlula kalula ku-90°F (32°C), okungalimaza izitshalo ezizwelayo. Kulezi zimo, izitshalo ezifana nolethisi nesipinashi zingabuna, ziyeke ukukhula, noma zife. Ukuze ugweme lokhu, izinyathelo zokupholisa ezengeziwe ezifana nezinhlelo zokungenisa umoya noma shading ziyadingeka, okwengeza kokubili izindleko kanye nobunzima bokuphatha ukushisa.
Ukudluliswa Kokukhanya: Ingabe Izitshalo Zakho Zizothola Ukukhanya Kwelanga Okwanele?
Ngenkathi ipulasitiki ivumela ukukhanya ukuthi kungene ku-greenhouse, ayikugcini ukudluliswa kokukhanya okungaguquki ngokuhamba kwesikhathi. Imisebe ye-UV evela elangeni yenza ipulasitiki yonakale, ibe phuzi, futhi ilahlekelwe ukukhanya kwayo. Ikhava yepulasitiki eqala ukungena ku-80% wokukhanya ingase yehle ibe ngu-50% noma ngaphansi ngemva kweminyaka embalwa nje. Lokhu kuncipha kwamandla okukhanya kunomthelela ku-photosynthesis, okubuye kubambezele ukukhula kwezitshalo futhi kunciphise isivuno nekhwalithi. Izindlu zokugcina izithombo zengilazi, ikakhulukazi lezo ezinengilazi ehlukanisayo yekhwalithi ephezulu, zigcina ukuthunyelwa kokukhanya okuzinzile nokungaguquguquki isikhathi eside.
Ukuqina: Ingabe Kuzohlala Isikhathi Eside?
Izindlu zokugcina izithombo zepulasitiki zivame ukuba nesikhathi esifushane sokuphila uma kuqhathaniswa nengilazi noma ezinye izindlela zensimbi. Ngisho namapulasitiki amelana ne-UV ngokuvamile ahlala cishe iminyaka emi-3-4 ngaphambi kokuba aqale ukuwohloka. Izinto zepulasitiki ezivamile ziwohloka ngokushesha okukhulu. Ukwengeza, izembozo zepulasitiki ezincane zivame ukudabuka, ikakhulukazi ezindaweni ezinomoya onamandla noma isichotho. Isibonelo, ezifundeni lapho imimoya ivame khona, izindlu zokugcina izithombo zepulasitiki zivame ukudinga ukulungiswa njalo noma ukushintshwa okuphelele. Ngisho nepulasitiki ewugqinsi, impahla ingaqhekeka ngenxa yokwanda nokufinyela kusuka ekushintsheni kwezinga lokushisa, kuqhubeke nokunciphisa isikhathi sayo sokuphila. Uma kuqhathaniswa, izindawo zokugcina izithombo zengilazi zingahlala iminyaka engama-40-50 ngokuwohloka okuncane, zinikeze ukuqina okungcono kwesikhathi eside.
Umthelela Nokugcinwa Kwemvelo: Ingabe Ivumelana Nemvelo Ngempela?
Ukungcoliswa Kwepulasitiki
Ekupheleni kwesikhathi sabo sokuphila, izindlu zokugcina izithombo zepulasitiki zifaka isandla ekungcoleni kwemvelo. Iningi lepulasitiki elisetshenziswa kulezi zakhiwo alikwazi ukuphinda lisetshenziswe, okusho ukuthi ligcina selisendaweni yokulahla imfucumfucu lapho kungathatha amakhulu eminyaka ukubola. Ukukhiqizwa kwepulasitiki kuhlanganisa nokukhipha nokucubungula amafutha ezinto ezimbiwa phansi, okuholela ekukhishweni kwekhabhoni ephezulu. Ngokuphambene, ezinye izindlela ezisimeme njengengilazi egaywe kabusha noma amapulasitiki abolayo anomthelela ophansi kakhulu kwezemvelo.
Izidingo Zokugcinwa Okuphezulu
Izindlu zokugcina izithombo zepulasitiki zidinga ukunakekelwa njalo. Isembozo sepulasitiki sidinga ukuhlolwa njalo ukuze kutholakale izimbobo noma izinyembezi, okufanele zilungiswe ngokushesha ukuze kuvinjelwe ukushisa noma ukulahlekelwa umswakama. Ipulasitiki kufanele futhi ihlanzwe ngezikhathi ezithile ukuze igcine ukukhanya kwayo. Le misebenzi ingadla isikhathi futhi isicefe. Ukwengeza, amafreyimu angasindi wezindlu zokugcina izithombo zepulasitiki, nakuba engabizi, angeke aqine njengezakhiwo zensimbi noma zengilazi. Zidinga ukuhlolwa nokulungiswa kaningi ukuze kuqinisekiswe ukuthi zihlala ziphephile futhi zisebenza ngokuhamba kwesikhathi.
Izindlu zokugcina izithombo zepulasitiki zinikeza izinzuzo ezithile njengezindleko eziphansi zokuqala nokufakwa kalula. Kodwa-ke, futhi beza nemikhawulo eminingana engabenza bangakufanelekeli ukusetshenziswa isikhathi eside. Kusukela ezindabeni zokuqina, ukudluliswa kokukhanya, nokugcinwa kokushisa kuya ekunakekeleni okuphezulu nokukhathazeka kwemvelo, kubalulekile ukukala lezi zici ngokucophelela ngaphambi kokwenza isinqumo. Ukuqonda ubuhle nobubi bezinto ezihlukene ze-greenhouse kuzokusiza ukhethe inketho engcono kakhulu yezidingo zakho ezithile nendawo.
Siyakwamukela ukuba nengxoxo eyengeziwe nathi.
