20.500.12556/DKUM-38386 Stopnja redukcije zanašanja škropilne brozge treh antidriftnih šob pri nanosu škropilne brozge v ječmenu Drift reduction rate of three antidrift nozzles used for spray application in barley Na polju ječmena smo izvedli poskuse, s katerimi smo preučevali možnosti zmanjševanja zanašanja (drift) FFS z uporabo antidriftnih šob. Pri aplikaciji FFS smo merili delež škropilne brozge, zanesene na razdaljah 0, 1, 2, 5 in 10 m stran od roba njive z uporabo fluorescentnega sledilca. Vse meritve so bile opravljene v štirih ponovitvah. Primerjali smo obseg zanašanja pri standardni šobi (Lechler LU 120-03) in treh antidriftnih šobah (Lechler ID 120-03, Albuz AVI – TWIN 110-03 in AGROTOP Turbodrop HiSpeed 110-03) pri nanosu 250 l škropilne brozge na hektar. Delež zanesene škropilne brozge se je z razdaljo od roba njive na vseh merjenih razdaljah zmanjševal. Najmanjši drift je bil dosežen s šobo HS. Na delež drifta je značilno vplivala velikost kapljic, kjer je bil drift največji pri šobi LU (VMD = 185). Pri uporabi različnih tipov šob s podobnimi velikosti kapljic in s približno enakimi hitrostmi vetra v času nanosa, je drift enak. Antidriftne šobe so za 70–85 % zmanjšale drift na vseh merjenih razdaljah. We have done experiments on a field of barley where we have studied a possibility of lowering the drift FFS with using the antidrift nozzles. After applying, we have measured a share of spray deposit on the distance of 0, 1, 2, 5 and 10 meters away from the edge of the field using the fluorescent tracker. All measurements have been done in four repetitions. We have compared a perimeter of skidding with standard nozzle (Lechler LU 120-03) and three antidrift nozzles (Lechler ID 120-03, Albuz AVI – TWIN 110-03, and AGROTOP Turbodrop HiSpeed 110-03) with a deposit of 250 liters of spray deposit on hectare. A share of spray deposit that was skid lowered with the distance from the edge of the field with all measured distances. The smallest drift was achieved with the nozzle HS. The size of the droplets significantly influenced the part of the drift where the drift was the biggest with the nozzle LU (VMD = 185). When using different types of nozzles with similar sizes of droplets and approximately same speeds of wind in the time of deposit the drift is the same. Antidrift nozzles lowered the drift for 70–85% on all measured distances. ječmen stopnja redukcije antidriftne šobe standardne šobe zanašanje FFS barley reduction rate drift-reducing nozzles standard nozzles drift true true false Slovenski jezik Angleški jezik Magistrsko delo 2012-09-25 10:34:48 2012-10-04 14:01:23 2022-04-26 11:29:40 2021-04-20 03:17:00 2012 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:AKDKI2DB MAG_Plevnik_Katarina_2012.pdf MAG_Plevnik_Katarina_2012.pdf 1 19FB81BAF2C1743DBDEA1A5EF7CC0469 2d4f8cfd95b9cbe26e23edc6027f07ab4778947288fda8f4287263ab8dddf06e 7d001b9f-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/0db13cbb-4db4-4264-b4ed-28f1d5efdea8 https://dk.um.si/Dokument.php?lang=slv&id=51272 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
