20.500.12556/RUL-150824 Vpliv izmenične obdelave medvrstnega prostora znotraj vinogradov na kakovost tal Influence of inter-row cultivation in vineyards on soil quality Za doseganje želene rodnosti trt ter kakovosti grozdja je potrebno korektno izvajanje agro-ampelotehničnih ukrepov. Pomembnejši agrotehnični ukrep je obdelava tal medvrstnega prostora vinograda, pri katerem je potrebno upoštevati okoljske razmere, potrebe trte in druge naravne danosti območja. Namen naloge je bil ugotoviti razlike v kakovosti redno kultiviranega oziroma obdelanega (OBT) medvrstnega prostora vinogradnih tal in tal medvrstnega prostora s trajno ozelenitvijo (OZT). Poskus smo opravili v treh vinogradih Purissima, Baredi in Ricorvo v lasti Vinakoper d.o.o. v vinorodnem okolišu Slovenska Istra. Na vseh treh lokacijah so vinogradi postavljeni vzdolž plastnic na evtričnih rjavih tleh na karbonatnem flišu, v katerih je izmenjujoče upravljanje medvrstnega prostora (kultiviran in trajno zelenjen) več kot deset let. S poskusom smo potrdili, da imajo OZT tla medvrstnega prostora vinograda v povprečju večjo vsebnost organske snovi, boljšo obstojnost strukturnih agregatov ter posledično boljše lastnosti, ki so odvisne od strukture. V OBT brez rastlinskega pokrova z obdelavo prekinemo kapilarni dvig ter tako zmanjšamo izhlapevanje vode. V vinogradu z največjo gostoto tal, kjer so se izsledki najbolj razlikovali od ostalih dveh obravnavanih vinogradov, smo ugotovili, da s porušenjem strukture tal omogočimo boljšo infiltracijo na tleh brez rastlinskega pokrova. Glede na dobljene rezultate priporočamo izmenično trajno ozelenitev v medvrstnem prostoru vinogradov, saj z ozelenitvijo ohranjamo kakovostna tla z večjo vsebnostjo organske snovi in dobro strukturo ter z golo obdelavo v vsaki drugi vrsti zagotovimo večjo dostopnost vode vinski trti. Za podrobnejše izsledke bi bilo v prihodnje potrebno razširiti raziskavo, dodati izsledke o talni mikrobni dejavnosti ter večletne podatke o količini in kakovosti pridelka pri različnih načinih upravljanja vinogradnih tal. Correct implementation of agro-ampelotechnical measures and appropriate cultivation of the soil between the rows according to the needs and natural conditions of the vineyard are the key to achieving the desired vine productivity and grape quality. The study aims to determine the differences in soil quality between regularly tilled soils without vegetative cover and permanent green cover. The experiment was carried out in three vineyards, Purissima, Baredi and Ricorvo, owned by Vinakoper d.o.o. in the wine-growing region of Slovenska Istra. In all three locations, the vineyard is laid out along the layer lines of a slope on eutric brown soils (Cambisol) on carbonate flysch, where permanent rotational cultivation of the inter⠒row space has been carried out for more than ten years. The experiment confirmed that the permanently greened soil (OZT) of the vineyard inter-row space has, on average, a higher organic matter content, better persistence of structural aggregates and, consequently, better structure-dependent properties. In treated inter-row space (OBT) without vegetative cover, the treatment interrupts the capillary rise and thus reduces water evaporation. In the vineyard with the highest soil density, where the results differed the most from the other two vineyards considered, we found that breaking down the soil structure allows better infiltration in the soil without vegetative cover. In the light of the results obtained, we recommend alternating permanent green cover in the inter-row space of the vineyards (alternating inter-row cultivation), as use of green cover maintains good quality soils with a higher organic matter content and a good structure, and bare tillage in every other row ensures greater water availability to the vines. For more detailed results, the study should be extended in the future to include results on soil microbial activity and multiannual data on the quantity and quality of yields under different vineyard soil management practices. vinograd obdelava medvrstnega prostora trajna ozelenitev obdelana tla lastnosti tal organska snov vodozadrževalne lastnosti struktura infiltracija vineyard inter-row cultivation permanent green cover tilled soil soil properties organic matter water retention properties soil structure infiltration true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2023-09-24 07:16:21 2023-09-24 07:16:28 2023-09-26 09:00:50 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 231097 165738755 36278.pdf 36278.pdf 1 00AFA2A6D2F9C1071CE9F32FB61FCA10 3552e753f39c48593def8b970f44ac4078a78898d01e8494dada35856d44666a 849907e8-5a99-11ee-baf2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=175638 Biotehniška fakulteta 0 0 0
