20.500.12556/DKUM-55567 PRIMERJAVA DVEH SISTEMOV PRIDELAVE JABOLK SORTE TOPAZ A comparison of two systems of apple production at variety Topaz V letih 2012 in 2013 je bil na posestvu Fakultete za kmetijstvo in biosistemske vede Univerze v Mariboru izveden poskus v ekološkem nasadu jablan sorte Topaz. V diplomskem delu smo ugotavljali, kako zasaditev nekaterih zeli in grmovnic med jablanova drevesa vpliva na pojav škodljivcev in bolezni v nasadu. V prostoru med drevesi smo zasadili zeli – pravi pelin in rožmarin – ter grmovnice, ribez, lesko in bezeg, s čimer smo spremenili mikro ekosistem nasada. Nasad smo večkrat letno obdelali ali pa smo pustili rasti zeleno podrast. Pri polovici nasada smo zatirali škodljivce in bolezni z ekološkimi pripravki, za drugo polovico pa nismo uporabljali nikakršnih sredstev za varstvo rastlin. Rezultati kažejo, da ima sajenje zeli in grmovnic med jablanova drevesa vpliv na populacijsko dinamiko škodljivcev in koristnih žuželk. Uporaba ekoloških pripravkov je nekoliko zmanjšala populacijo koristnih žuželk. Najbolj očiten je bil vpliv ekoloških pripravkov pri sicer zelo majhni populaciji plenilskih pršic. Pokazalo se je tudi, da ima lahko posamezna rastlina pozitiven učinek na koristne in škodljive žuželke. Tako bi morda zaradi sajenja leske med jablanova drevesa lahko imeli več plenilskih pršic in jabolčnega zavijača, a manj uši. Podsajanje preučevanih rastlin med jablane bi vsekakor povečalo pestrost koristnih žuželk v nasadu jablan. In years 2012 and 2013 an experiment in an organic orchard of Topaz apple trees was conducted at the estate of the Faculty of Agriculture and Life Sciences, University of Maribor. Our aim was to determine, how planting specific herbs and shrubs between apple trees impacts the emergence of pests and diseases in an ecological apple tree orchard. In the space between the trees we had planted herbs: common wormwood and rosemary; and shrubs blackberries, hazel and elder. With this we changed the micro-ecosystem of the orchard. At the same time we have had unmanaged green understory for a whole year. In a half of the orchard we conducted pest and disease control using organic products, and in the other half we did not use any products for plant protection. The results show that planting herbs and shrubs between apple trees has an impact on the population dynamics of pests and beneficial insects. The use of organic sprays somewhat reduced the population of beneficial insects. The most evident was the impact of organic sprays in a very small population of predatory mites. It was also shown that a specific plant can have the opposite effect with one type of beneficial or harmful insect, than with the other. Due to planting hazel between apple trees we could thus perhaps have more predatory mites, less aphids, but more codling moth. Planting the studied plants would certainly increase the diversity of beneficial insects in the apple tree orchard. jablana škodljivci naravni sovražniki populacijska dinamika zeli grmovnice apple pests natural enemies population dynamics herbs shrubs true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-11-26 20:57:34 2016-01-29 09:37:23 2022-06-09 03:09:20 2021-05-15 03:15:50 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:WNQ2AO3R VS_Veber_Renata_2015.pdf VS_Veber_Renata_2015.pdf 1 A5D502A76CC0427D5B8081A8AB2DDE28 2a72d8ccf50a8886d2be3a2eb2330171fad0c32719cefe794745ae11eb226a67 d0ceafb1-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=83320 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
