20.500.12556/DKUM-38072 NEGATIVEN VPLIV VISOKIH KONCENTRACIJ SUHE SNOVI V GNOJEVKI NA VZNIK IN ZAČETNO RAST NEKATERIH TRAVNIŠKIH RASTLIN The negative impact of high dry matter concentrations in slurry on the emergence and initiating the growth of some meadow plants Negativni vplivi gnojevke pri gnojenju travinja še vedno predstavljajo velik problem v kmetijstvu. Na to temo smo na Fakulteti za kmetijstvo in biosistemske vede leta 2011 izvedli lončni poskus v rastlinjaku in poskus z gnojevko na travniku. V poskusu smo proučevali vpliv visokih koncentracij suhe snovi v gnojevki na kalivost in začetno rast ozkolistnega trpotca (Plantago lanceolata L.), divjega korenja (Daucus carota L.), trpežne ljuljke (Lolium perenne L.), bele detelje (Trifolium repens L.) in navadnega regrata (Taraxacum officinale Weber). Oba poskusa sta bila zasnovana kot trofaktorska: rastlina, gnojevka in koncentracija gnojevke. Uporabili smo dve gnojevki iz različnih govedorejskih kmetij, ki smo ju redčili na 4, 7 in 10 % suhe snovi. V kontrolnem obravnavanju smo uporabili samo vodo. V povprečju čez vse rastlinske vrste višje koncentracije suhe snovi v gnojevki negativno vplivajo na kalitev in začetno rast. Ugotovili smo, da vse rastlinske vrste ne odreagirajo enako na enake koncentracije suhe snovi. Pri uporabi gnojevke na travinju je potrebno predhodno redčenje gnojevke z vodo. Prav tako smo prišli do zaključka, da se moramo v sušnem in vročem obdobju apliciranju gnojevke na travniku izogniti, saj se lahko gnojevka izsuši in se še poveča vsebnost suhe snovi, kar neugodno vpliva na vznik rastlin. The negative influences of the slurry when fertilizing grassland still represent a vast problem in agriculture A pot experiment in a greenhouse and an experiment with slurry on a meadow were carried out at Faculty of Agriculture and Life Sciences in 2011.The effect of high dry matter concentrations in slurry on germination and on growth initiating of the ribwort plantain (Plantago lanceolata L.), wild carrots (Daucus carota L.), resilient ryegrass (Lolium perenne L.), white clover (Trifolium repens L.) and on the common dandelion (Taraxacum officinale Weber) were studied in both experiments. Designed as a three-factor experiment: the plant, the slurry and the slurry concentration. We used two different slurries from two different beef-producing farms and have diluted it to a 4,7 and a 10% of dry matter. In the control treatment we used only water. Overall, the higher concentrations of dry matter in slurry have a negative effect on the germination and on the initiating the growth on average, taking all the plant species into considderation. We found that all the plant species do not react the same way to same dry matter concentration values. By using slurry on the meadows a previous dilution with water is necessary. Also, we have reached a conclusion that in periods of dry and sunny weather we have to avoid using slurry, since it can dry out and consequently increases slurry dry matter content, which is disagreeable with the plant initiating. ozkolistni trpotec navadni regrat trpežna ljuljka bela detelja divje korenje kalivost semena gnojevka ribwort plantain common dandelion resilient ryegrass white clover wild carrots germination of seed slurry true true false Slovenski jezik Angleški jezik Diplomsko delo 2012-09-17 08:40:13 2012-10-08 18:49:13 2022-04-25 23:09:26 2021-04-19 03:22:35 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:W0FKAAWP UNI_Gornik_Katja_2012.pdf UNI_Gornik_Katja_2012.pdf 1 5F5D24742370769C1A41929C661DFDB2 066c8a9f07b5d5d0e5941a9398b7596b6de970939eb1354421204b6c6be8cba8 688d57bd-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/78915baa-406b-4eda-bd39-2bb9732a37a3 https://dk.um.si/Dokument.php?lang=slv&id=50607 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
