20.500.12556/DKUM-90762 Avtoregulatorna vegetacija v pasu pod drevesi jablan magistrsko delo Autoregulatory in-row non-competitive plant communities in apple orchards Pleveli v vrstnem prosotru so jablanam konkurenčni za hranila in vodo, zato se v standardni tehnologiji pridelave rastlinstvo v pasu pod drevesi zatira z uporabo herbicidov. V zadnjem času je v porastu uporaba alternativnih metod za zatiranje plevela. Ena izmed njih je setev pokrovnih posevkov. V letih od 2021 do 2023 smo v okviru projekta »IPM works« preizkušali izvedljivost sistema avtoregulatorne vegetacije v pasu pod drevesi na kmetiji Marko. Cilj poskusa je bil ugotoviti vpliv avtoregulatorne sejane vegetacije na kakovost in količino plodov ter na vegetativni prirast jablan. V vrstnem prostoru jablan smo sejali mešanico cvetočih enoletnic, mešanico cvetočih trajnic in sojo. Iz pridobljenih rezultatov je razvidno, da sejana avtoregulatorna vegetacija z leti učinkovito prevlada nad avtohtono plevelno podrastjo, ki je prisotna v vrstnem prostoru v nasadu jablan. Soja ima pozitiven vpliv na enoletni prirast poganjkov jablan. Avtohtona podrast in cvetoče enoletnice imajo pozitiven vpliv na prirast obesega debla jablane. Količina pridelka jabolk v obravnavanjih s sejano avtoregulatorno vegetacijo je primerljiva s količino pridelka iz obravnavanja avtohtone podrasti. Glede na rezultate poskusa je vpeljevanje avtoregulatorne vegetacije z različnimi cvetočimi mešanicami v vrstni prostor v sadovnjaku iz vidika zatiranja avtohtone podrasti učinkovito in nima negativnega vpliva na količino in kakovost pridelka. Weeds growing in row space compete with apple trees for nutrients and water. This aforementioned detrimental competition is why herbicides are used to control the vegetation in the strip below the trees in standard apple growing systems. Recently, the use of alternative weed control measures has been on the rise. One of these measures is the sowing of cover crops. In 2021 and 2023, as part of the »IPM works« project, we tested the feasibility of an autoregulatory undergrowth system in the strip under apple trees at the Marko Farm. The aim of the experiment was to determine the impact of autoregulatory undergrowth on the fruit quality and quantity, and on the vegetative growth of apple trees. In the apple tree rows, a mixture of flowering annuals, flowering perennials and soybeans was sown. The results obtained show that over the years the sown autoregulatory undergrowth effectively prevails over the native vegetation present in the apple orchard row spaces. Soybeans have a positive effect on the annual shoot increment of apple trees. Native undergrowth and flowering annuals have a positive effect on the increase in trunk volume of apple trees. The yield of apples in the treatments sown with autoregulatory undergrowth is comparable to the amount of yield in the treatment with the native undergrowth. According to the results of the experiment, the introduction of living mulch from different flowering mixtures into the row space of the orchard was effective in terms of suppressing native undergrowth and had no effect on the quantity and quality of the apple fruits. jablana vrstni prostor avtoregulatorna vegetacija avtohtona podrast pridelek apple tree row spacing autoregulatory undergrowth native undergrowth crop true true false P.
