20.500.12556/RUL-78498 Primerjava naravne in umetne obnove gozdov, prizadetih v naravnih ujmah Comparison of natural and artificial regeneration of forests affected in natural disturbances Podnebne spremembe vplivajo na slabšo odpornost in vitalnost gozda, povečuje se pogostnost naravnih ujm. V raziskavi smo primerjali učinkovitost naravne in umetne obnove gozdov, prizadetih zaradi ujm, s poudarkom na strukturi in rasti mladja, vplivu pritalne vegetacije in pomenu semenskih dreves. Prva raziskava proučuje uspeh setve pri treh različnih načinih dela (1: priprava tal, setev, ograditev; 2: setev, ograditev; 3: setev in saditev). V drugi raziskavi smo primerjali uspešnost naravne obnove in umetne obnove (saditve) po vetrolomu. Rezultati kažejo, da na nasemenitev pozitivno vplivata bližina semenskih dreves in priprava tal, medtem ko zastrtost s pritalno vegetacijo vpliva negativno. Gostote naravnega mladja na ploskvah z naravno obnovo so večje od tistih na ploskvah z umetno obnovo (brez upoštevanja sadik). Climatic changes affect minor resistance and vitality of the forest, incidence of natural disturbances increases. In this research we compared efficiency of natural and artificial restoration of forests affected by natural disturbances; the stress was laid on structure and growth of seedlings, impact of ground vegetation, and importance of seed trees. The first study compares success of regeneration according to three diverse treatments (1: preparation of soil, sowing, fencing; 2: sowing, fencing; 3: sowing and planting). In the second research we compared success of natural regeneration and artificial regeneration (planting) after windthrow. The results show that regeneration is positively affected by proximity of seed trees and soil preparation, while the impact of ground vegetation cover is negative. The densities of naturally grown seedlings on plots with natural regeneration surpass the ones on plots with artificial regeneration (disregarding planted seedlings). ujme vetrolomi pomlajevanje naravna obnova saditev setev semenska drevesa true false false Zveza društev inženirjev in tehnikov gozdarstva in lesarstva Slovenije Slovenski jezik Angleški jezik Znanstveno delo 2015-12-30 13:00:28 2015-12-30 13:00:28 2022-07-24 03:43:11 0000-00-00 00:00:00 2013 0 0 Str. 19-25 št. 1 Letn. 71 feb. 2013 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*22:630*23+630*42/43(045)=163.6 0017-2723 3560102 3736834 http://www.dlib.si/details/URN:NBN:SI:doc-LUEXJE3W 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=78542 Biotehniška fakulteta 0 0 0
