20.500.12556/DKUM-62298 Pridelovalni in fitoremediacijski potencial industrijske konoplje (Cannabis sativa L.) Growing and Phytoremediational Potential of Hemp (Cannabis sativa L.) Čiščenje onesnaženih tal je zahtevno, še posebej, ko gre za težke kovine. Naraven način čiščenja tal imenujemo fitoremediacija. Uporabimo rastline, ki jih imenujemo hiperakumulatorji in v tkivih akumulirajo več kot 0,1 % Pb, Co, Cr in več kot 1 % Mn, Ni ali Zn. Med potencialne hiperakumulatorje spada konoplja (Cannabis sativa L.), ki smo jo analizirali s študijem predvsem tuje literature iz baz Sciencedirect, ProQuest in Web of Science in skozi lastno preliminarno raziskavo, katere rezultate smo vključili v primerjavo. Največji vpliv na pridelek konoplje ima kombinacija zgodnje setve in visoke setvene norme okrog 250 rastlin/ m². Konoplja glede na vire akumulira med 1,1 in 136,9 mg Pb/kg suhe snovi. Glede na pričakovan pridelek 10 t/ha mora rastlina akumulirati vsaj 10 kg Pb/ha, kar pa konoplja z odvzemom 10 t/ha ni dosegla. Konoplja akumulira z dodajanjem kelatnih ligandov višje koncentracije Pb iz tal, ki so še vedno prenizke, da bi jo identificirali kot hiperakumulator svinca. V primerjavi s sončnico (H. annus L.), oljno ogrščico (B. napus L.), lanom (L. usitatissimum L.) in koruzo (Zea myas L.) pa konoplja med poljščinami akumulira najvišje koncentracije Pb. Za uspešnejšo fitoremediacijo onesnaženih tal lahko kolobar kombiniramo z dvema rastlinama, ki akumulirata Pb, npr. konoplja in oljna ogrščica. Konoplja z veliko vsebnostjo Pb ima potencial v gradbeništvu, papirni industriji ali za izdelavo kompozitov. Za uživanje ali izdelavo oblačil ni primerna. Cleaning of contaminated soil is a challenge, especially extraction of heavy metals. Phytoremediation is a natural way of cleaning such soil. Plants that accumulate more than 0.1 % of Pb, Co, Cr or more than 1 % of Mn, Ni or Zn are called hyperaccumulators. One of the potential hyperaccumulators is hemp (Cannabis sativa L). Based on literature review (Sciencedirect, ProQuest and Web of Science) and preliminary research, the effects of variety and plant population in hemp on phytoremediation and production were studied. A combination of early sowing and high density of plants (around 250 plants/m2) has the highest impact on hemp yield. Research shows that hemp accumulates 1.1 to 136.9 mg Pb/kg of dry matter. Regarding the expected yield of 10 t/ha, a plant should accumulate more than 10 kg Pb/ha, which hemp does not reach with the uptake of 10 t/ha. By adding chelates, the concentration of accumulated Pb rises, but is still too low to justify classifying hemp as a hyperaccumulator of heavy metals (namely Pb). However, hemp accumu-lates higher concentrations of Pb in comparison with sunflower (H. annus L.), canola (B. napus L.), flax (L. usitatissimum L.) and maize (Zea myas L.). A combination of two Pb accumulating plants in a crop rotation could have a positive effect on Pb accumulation, for example hemp and canola. Contaminated hemp can potentially be used in building, in paper industry or for composites. Regardless, such hemp is not recom-mended for ingestion or textiles. konoplja fitoremediacija onesnaženje okolja odvzem svinca pridelek hemp phytoremediation pollution of environment lead extraction crop true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-08-25 10:26:51 2016-08-31 08:50:50 2022-06-29 03:07:39 2019-07-11 12:50:43 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:AONJWCDG UN_Klavz_Dominika_2016.pdf UN_Klavz_Dominika_2016.pdf 1 3B86FF35A092012090C3900B5B3954EB 09b97222795467935795202c29b4b6d8e1d1b22c67af3d932d473867b3646e4a 1e4995c0-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=100010 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
