Abstract:	Za potrebe intenzivne pridelave hrane se vedno več rastlin goji v zavarovanih prostorih, kjer so rastline zaščitene pred neželenimi vremenskimi vplivi. Zavarovani prostori so lahko povsem enostavni objekti pokriti z različnimi folijami ali pa najsodobnejši steklenjaki z avtomatskim uravnavanjem klime. V letu 2017 smo na domači njivi na Pobrežju postavili štiri nizke tunele in jih prekrili z različnimi prekrivkami, in sicer z PE folijo debeline 60 µm in 150 µm, z PE folijo debeline 60 µm, ki je bila naluknjana in z 19 g PP folijo oziroma kopreno. V obdobju od 20. 4. 2017 do 18. 5. 2017 smo z dataloggerjem CR1000 podjetja Campbell Scientific konstantno merili zunanjo temperaturo in temperaturo v tunelih. Kot najprimernejša prekrivka se je izkazala koprena, saj je rastlinam nudila višje temperature ponoči, podnevi pa se v tunelih ni segrelo preveč. Kot neprimerni za prekrivanje nizkih tunelov sta se izkazali PE foliji debelin 150 in 60 µm, saj se je že ob zunanjih temperaturah nad 10 °C v njih ogrelo preko 40°C. Za poskusno rastlino smo v tunele posadili sadike nizkega fižola, vendar jih je že v prvi noči merjenja skoraj v celoti uničila zunanja temperatura -4,2°C.

Title:	Measurements of Microclimate in Low-Tunnels with Different Covers
Abstract:	For the needs of more intensive food production, more and more plants are grown in protected areas, where the plants are also protected from adverse weather effects. Protected areas can be simple objects covered with different foils or state-of-the-art glass bottles with automatic climate control. In 2017, four low tunnels were erected on a home field in Pobrežje and covered with different overlays, namely PE film with a thickness of 150 μm and 60 μm, PE film with a thickness of 60 μm, which was punched, and with 19 g PP film or agryl. In the period from April 20, 2017 to May 18, 2017, Campbell Scientific's CR1000 datalogger constantly measured the outside temperature and the temperature in the tunnels. The agryl was the most appropriate cover, providing plants with higher temperatures at night and did not warm the tunnels too much during the day. PE films of 150 and 60 µm thicknesses, proved to be unsuitable for covering low tunnels, since they already heated above 40 °C at outdoor temperatures of above 10 °C. Low bean seedlings were planted in the tunnels as the test plant, but were almost completely destroyed by -4.2 ° C on the first night of measurement.
