Ubani owayengacabanga eminyakeni eyishumi eyedlule ukuthi sizokwazi ukuthonya ukukhula kanye nokuhluma kwezilimo zezitshalo nezensimu ngosizo lombala wombala wezingubo zokushisa okushisa?
Ngaphezu kokunakekelwa okujwayelekile. Umbala we-polycarbonate okhethiwe kahle uzosiza ukuze ukhule izitshalo eziqinile futhi udale izimo ezifanele zokuvunwa okuphezulu.
Ake sizame ukubona ukuthi iyiphi i-polycarbonate embala engcono ukuyisebenzisa ukuze kusetshenziswe ukushisa.
Scientifically
Ukukhanya kwelanga kuyadingeka ukuze izitshalo zikhule, zithwale futhi zizalise. Lokhu esikwaziyo kusukela kwizifundo zesikole ze-botany. Ukuthola ilanga elihlanzekile ku-greenhouse akunakwenzeka, ngoba noma yikuphi ukugqoka kubamba ezinye zazo.
Kungenzeka yini ukumboza i-greenhouse nge polycarbonate enemibala? Kwakuhlale kukholelwa ukuthi indaba yokugubha izithombo zokugcina kufanele ibe yinto ecacile ngangokunokwenzeka.
Nokho, maduzane, abalimi sebeqalile ukusebenzisa i-polycarbonate enemibala ngale njongo, ngenkathi bekhetha ama-shades aphuzi, ama-orange nebomvu. Kungani ukhetha i-polycarbonate ezindaweni zokugcina izithombo? Iyini umbala omuhle kakhulu?
Imiphumela yombala ezitshalweni
Yimuphi umbala we-polycarbonate ongcono ngokukhetha ukushisa okushisa? I-spectrum ekhanyayo limelela amagagasi kagesi ahlukene ubude. Abanye babo benza ngezitshalo ngokulimaza, abanye - bazuzisa.
Konke kuncike ekutheni lokhu noma lokho kukhanya kudonswa yi-chlorophyll - omunye wabahlanganyeli abakhulu ku-photosynthesis. Ubude be-wavevel magnetic we-electromagnetic kulinganiswa ngamanometers (nm).
I-280 nm yavelength ikhona i-ultraviolet enzima, ayibonakali emehlweni ethu futhi anethonya elibi kokubili kumuntu nesitshalo. Iveza amaqabunga, amaphuzu akhula afa. Izinzuzo ze-polycarbonate ukuthi zithinta ngokuphelele le mibala.
Ingxenye ye-ultraviolet ye-spectrum nge-wavelength yama-280 kuya ku-315 nm inikeza ekuqiniseni kwezitshalo futhi yandisa ukumelana nokubandayo. Amagagasi e-electromagnetic aphakathi kuka-315-380 nm athuthukisa ukuguguquka komzimba futhi akhuthaze ukukhula. I-Polycarbonate ilahlekelwa yimilayezo ye-ultraviolet.
I-spectrum eluhlaza cishe ayinakuthwa yizitshalo, naphezu kokuthi ingxenye "eluhlaza" (550 nm) ukuthi ukuphakama kwelanga okubonakalayo kweso kuyatholakala. Ukuba ngaphansi komthelela walo mbala, lesi sitshalo siqala ukubola, sinciphise ukuthuthukiswa nokulula.
Ama-Shades of purple-blue (380 - 490 nm) iyasiza ekuthuthukiseni nasekukhuleni. Umbala we-Violet uthinta ukwakheka kwamaprotheni kanye nesilinganiso sokukhula kwezitshalo. Kulo mkhakha, kuhle ukutshala izitshalo zelanga elifushane, ziqhakaza ngokushesha.
Umbala obomvu umphumela ozuzayo ekukhuleni kobukhulu obuhlaza - i-stem namaqabunga. Uma i-blue hue ye-spectrum ilahlekile ekukhanyeni okubamba ukushisa, isitshalo singaqala ukweluleka ngokuqinile ukuthola umthamo wokukhanya.
Ukuze ukutshala izithelo izitshalo kahle ububanzi be-orange (620-595 nm) nombala obomvu (720-600 nm). Zizibandakanya kakhulu ngendwangu ye-photosensitive - i-chlorophyll futhi ibambe iqhaza ekwakheni ama-hydrocarboni. Lo mshini unikeza isitshalo ngamandla we-photosynthesis, futhi kuthinta izinga lokukhula.
Ukuzibonakalisa kwePolycarbonate
Ukukhethwa kwe-polycarbonate namuhla kukhulu kakhulu, kanye nobubanzi besicelo sayo. Phakathi kwezici zezobuciko zezinto ezibonakalayo, ukudluliswa okulula kudlala indima ebalulekile, ikakhulu uma isetshenziselwa ukugqoka izindawo zokugcina izithombo.
I-Polycarbonate yinto eguquguqukayo lapho ihlanganiswe. ukudlulisa okukhanyayo kuncike kusukela engxenyeni ye-bend nemigqa kusukela ku-82 kuya ku-90%.
I-polycarbonate embala enemibala ngeke isebenze. ukumboza izithombo zokugcina izithombo, kuvumela ngaphansi kwama-60% emisebe yelanga. Ngokuvamise ukusetshenziselwa amabhodlela lapho kufunwa khona isithunzi.
I-polycarbonate engafani futhi kuxhomeke ekujuleni kweshidiokungaba ngu-4 kuya ku-25 mm. Okuyingozi kakhulu, lokho kukhanya kancane. Kuzo zokugcina izithombo, ukuphakama kuka 4 kuya ku-16 mm kunconywa. Ukuzikhethela kuxhomeke kuhlobo lokushisa okushisa.
Ukushisa, njengomhlobiso we-dacha
Ukushisa kwama polycarbonate enemibala ngokwawo sekuvele umhlobiso. Indawo ekhanyayo phakathi kwemifino ye-dacha ihlale ijabulisa iso.
Uma ufuna isisombululo sokuklama, ungahlwanyela izihlahla ezihlotshisiwe futhi uzenzele indlela enhle eholele ekushiseni okushisa.
Ukuze ukuhlobisa izithombo zokugcina izithombo kusuka polycarbonate ongenemibala obala angasebenzisa umdwebouma i-butt greenhouse iqondiswa esiqhingini.
Kungenzeka ukusebenzisa umdwebo kuphela kule ngxenye yendawo yokushisa. Uphahla nezindonga zecala kumele zigcinwe zihlanzekile ukuze zingabonakali isikhala sangaphakathi.
Isithombe
Lapha ezithombeni kukhona izibonelo zezithombo zokugcina ezimibalabala kanye nezithombo zokugcina zokugcina izithombo ezinephethini.
I-Polycarbonate cishe isondeza ingilazi, njenge-dacha, kanye nezindawo zokugcina izitshalo.
