20.500.12556/DKUM-20769 MOŽNOST VEČKRATNE UPORABE T-TAPE CEVI V VRTNARSTVU Possibility of reusing T-Tape drip tape in horticulture V diplomski nalogi smo preučevali možnost večkratne uporabe T-tape cevi v vrtnarstvu, ki so po svoji zgradbi zelo enostavne in cenovno dostopne velikemu številu uporabnikov. Žal so zaradi enostavnih kapljačev tudi nezanesljive. V poskusu smo možnost večkratne uporabe cevi preučevali tako, da smo merili pretok posameznih kapljačev stare in nove cevi pri različnih naklonih položene cevi (0°, 1,5°, 10° in 15°). Pretok vode je bil pri novi cevi najmanjši pri naklonu 15º (11,44 ml/min) in največji pri naklonu 10º (13,78 ml/min), kar pomeni, da so kapljači občutljivi na preveliko hitrost vode. Pri stari cevi so pretoki statistično značilno manjši in znašajo pri naklonu 1,5º (8,53 ml/min) in pri naklonu 10º (9,94 ml/min). Iz rezultatov poskusa lahko zaključimo, da T-tape cevi zaradi prevelikih razlik v pretokih kapljačev in poškodb, ki nastajajo pri navijanju, niso primerne za večkratno uporabo, saj je namakanje preveč neenakomerno. In my dissertationi we have studied the possibility of re-using of T-Tape drip tape in horticulture. Those drip tapes simple by design and low price makes them affordable for a great number of users. Unfortunately they are also unreliable due to the drippers. In our experiment we have examined the possibility of reusing the tapes by measuring the flow of the drippers on the new and on the allready used tape. Those tapes were installed at different angles (0°, 1,5°, 10° in 15°). The results show, that the minimum flow was achieved at the angle of 15 degrees (11,44 ml/min) and the maximum flow at the angle of 10 degrees (13,78 ml/min), which indicates speed-sensitivity of the drippers. The measurements on the re-used tape shows, that flows are significantly lower. At the angle of 1,5 degrees the flow was 8,53 ml/min and at the angle of 10 degrees the flow was 9,94 ml/min. From the results of the experiment we can conclude, that the T-tape drip tapes are not suitable for re-using, because of excessive difference in the dripper flow and due to the damage of the tapes, made by winding them. Irrigation with re-used T-tape drip tapes would be highly uneven. namakanje kapljično namakanje T-tapeR cevi vrtnarstvo irrigation drip irrigation T-tapeR drip tape horticulture true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-09-30 09:45:40 2011-10-13 09:17:45 2022-04-14 08:14:32 2023-12-27 03:18:08 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:TM6RFM7O VS_Bedrac_Katja_2011.pdf VS_Bedrac_Katja_2011.pdf 1 2AA2D6D4AE1BEF28B5E905C129409324 fb75a0a1767e71bfc7a432b067846a879137f8a23fd33487b1f7dcc15905d1d4 b2c26e61-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/58519b21-2b0e-465c-9113-b18be386ab64 https://dk.um.si/Dokument.php?lang=slv&id=25968 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
