20.500.12556/DKUM-57565 VPLIV KAMENE VOLNE NA ZADRŽEVANJE VODE V SUBSTRATU The influence of rock mineral wool on water retention in pot substrate Namen diplomskega dela je bil preučiti vpliv kamene volne na zadrževanje vode v substratu. Poskus je potekal v letu 2013 v rastlinjaku Fakultete za kmetijstvo in biosistemske vede v Hočah. Obsegal je šest obravnavanj v treh ponovitvah in je bil zasnovan kot naključni blok. Obravnavanja so vsebovala različne deleže in oblike kamene volne (KV), ki smo jo primešali industrijskemu substratu (S) (vsako razmerje je predstavljalo posamezno obravnavanje). Ugotovili smo, da različni deleži in oblike kamene volne različno vplivajo na količino zadržane vode v substratu. Meritve količine vode smo izvajali vsakih 10 dni. Glede zadrževanja vode v substratu smo najboljšo sposobnost ugotovili pri obravnavanju 60 % KV + 40 % S (618,6 ml zadržane vode), najslabšo pa pri obravnavanju 20 % KV + 80 % S (353,7 ml zadržane vode). Dodatek kamene volne v obliki kock je prispeval k večji vlažnosti substrata. Kontrolno obravnavanje je v primerjavi z drugimi zadržalo zelo malo vode (372,6 ml). Med vlažnostjo in elektroprevodnostjo substrata smo ugotovili pozitivno korelacijo, saj smo pri izmerjenih večjih količinah zadržane vode izmerili tudi večjo elektroprevodnost v substratu. The main objective of the research was to study the influence of rock mineral wool on water retention in the substrate. The experiment was performed in the year 2013, in the greenhouse of the Faculty of Agriculture and Life Science, in Hoče. It consisted of six treatments in three repetitions and was designed as a randomized block. Different proportions and forms of rock mineral wool (RMW), mixed with industrial substrate (S) (each proportion presented individual treatment) were tested. We found that different proportions and forms of RMW had different effect on the amount of retained water in the substrate. Water measurements were performed in ten days intervals. The best results were obtained by the treatment with 60% RMW + 40% S, in which the amount of retained water was 618,6 ml, while the treatment with 20% RMW + 80% S showed the smallest amount of retained water (353,7 ml). Higher humidity of the substrate was achieved by using the rock mineral wool cubes. The control teratment held a very small amount of water (372,6 ml) when compared with other treatments. We found a positive correlation between humidity and electroconductivity in the substrate. A higher electroconductivity was measured at higher amounts of retained water in the substrate. kamena volna vsebnost vode elektroprevodnost substrat rock mineral wool water content electroconductivity pot substrate true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-02-26 17:09:26 2016-03-29 08:51:18 2022-06-14 03:06:31 2021-05-16 03:21:55 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2019-04-01 URN:SI:UM:DK:U2AUHZO6 VS_Purgaj_Natasa_2016.pdf VS_Purgaj_Natasa_2016.pdf 1 72D1478F9C2B2623C92B85D5937A0688 b083300c3658a4b8d2c90868a2eeea5740199255982131536b1cb3785c1505a1 eef724ee-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=86645 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
