Klima v zavarovanih prostorih

diplomsko delo

Jernej Kenk (Author), Ana Slatnar (Mentor)

Abstract

Po celem svetu so zavarovani prostori omogočili boljšo pridelavo zelenjave in okrasnih rastlin. Zavarovani prostori se ločijo glede na geografsko mesto pridelave, na katerega vpliva v veliki meri podnebje, in na tehnologijo, ki jo bomo uporabili v pridelavi za namene uravnavanja klime. Na uporabljeno tehnologijo vpliva tudi podnebje, saj se v toplejših oziroma hladnejših podnebjih ne poslužujemo uporabe enake tehnologije. V prvih je ta bolj enostavna in v večji meri zavzema prezračevanje in senčenje, v slednjih je tehnologija bolj napredna, saj so potrebe tudi po ogrevanju, zmanjševanju vlažnosti ter prej naštetih parametrov. Pomemben dejavnik pri izbiri zavarovanega prostora in vključene tehnologije za namene nadziranja klime je tudi izbira rastline, ki jo bomo gojili. Skupno rastline nimajo enakih zahtev za gojenje. Nekatere so bolj zahtevne, nekatere manj. Razlike med njimi se kažejo v optimalnih temperaturah za rast, v količini sončne svetlobe oziroma senčenja, zahtevah po zračni vlažnosti in potrebah po vodi. V bolj optimizirani pridelavi nekateri pridelovalci uporabljajo tudi obogatitev atmosfere s CO2, ki rastlinam omogoča boljše razmere za rast. Če vse dejavnike, podnebje in potrebe rastlin upoštevamo, in če klimo pravilno uravnavamo, so stroški manjši, pridelava pa je ekonomsko bolj upravičena. Z odgovornim ravnanjem s sistemi zmanjšamo emisije škodljivih plinov, s tem pa ravnamo odgovorno do okolja.

Secondary abstract:	Greenhouses all around the world enabled better production of vegetables and ornamental plants. They differ based on a climate of the geographical region and technology, that will be used for climate control. Climate also affects the technology. Regions with warmer or colder climates do not need the same climate control technology. Warmer climates require simpler control, that is mainly ventilation, because of higher temperatures, and shading. In latter technology has to be more complex. Besides ventilation and shading, there is also a need to heat the greenhouse and control the humidity in it. Technology is also affected by plant chosen. Different plants have different needs, especially optimal growth temperatures, amount of solar radiation recieved or needs for shading, air humidity and water needs. Growers with more advanced greenhouses use CO2 for atmosphere enrichment, which allow plants better growth conditions. If climate and plant needs are considered and if climate is controled well, than production is more efficient and expenses are lower. Responsible use of technology for climate control lowers harmful gas emissions, which makes production environmentally friendly.
