Abstract:V diplomski nalogi smo izvajali poskus, v katerem smo testirali delovanje ultrazvočnega sistema na pršilniku za trajne nasade. Poskus smo izvedli na jablanah poskusnega sadovnjaka Kmetijskega inštituta Slovenije, Brdo pri Lukovici, v letu 2010. V poskus je bil vključen štiriletni jablanov nasad dreves ’Gala’. Meritve smo izvajali v dveh ločenih poskusih z istim pršilnikom in sicer: v kontroliranem načinu (KN) brez uporabe ultrazvočnih senzorjev in v avtomatiziranem načinu (AN) z ultrazvočnimi senzorji. Nanos škropiva smo izmerili s pomočjo WSP lističev, ki so občutljivi na vodo. V poskus je bilo zajetih pet dreves in trije meddrevesni prostori za analizo in nanos škropiva. Na posameznem drevesu smo obravnavali devet območij, v praznih prostorih med drevesi pa tri območja. Pri kontroliranem načinu pršenja je bilo v povprečju s škropivom prekrite 12 % ciljne površine. Povprečno število kapljic, ki je zadelo posamezne obravnavane dele krošenj, je bilo 74 na cm². Pri avtomatiziranem načinu pršenja je bilo v povprečju s škropivom prekrite 14 % ciljne površine. Posamezne obravnavane krošnje dreves je zadelo povprečno 86 kapljic škropiva na cm². Ugotovitve kažejo, da med preizkušenima načinoma ni bistvene razlike v nanosu škropiva na posamezne dele drevesa, vendar je izmerjen 20,2 % prihranek škropiva, s tem pa so sorazmerno zmanjšani drifti v okolje.

Title:Testing an ultrasonic system on sprayer for permanent crops
Abstract:In the thesis, we tested an ultrasonic operation system on sprayer for permanent crops. The experiment was conducted in experimental apple orchard of the Agricultural Institute of Slovenia, Brdo pri Lukovici, in 2010 with four-year apple orchard trees ’Gala’. Measurements were carried out in two separate experiments with the same sprayer as follows: in a controlled mode (KN) without use of ultrasonic sensors and an automated mode (AN) with ultrasonic sensors. Spray application was measured using WSP papers, which are moisture sensitive. There were five trees and three between spaces involved in the experiment for analysis an application of spray. We selected nine zones on each tree, three regions between the trees for researching the deposit. On average 12 % coverage was measured in the controlled spray method and 14 % coverage in automated mode. The average number of drops per each WSP was 74 per cm² in the controlled spray method and 86 droplets per cm² in automated spray mode. The findings showed no significant difference between both spray applications, but we measured 20.2 % savings of spray. From this reason less drift was produced in the environment.
Keywords:Dispenser, ultrasound, algorithm, distribution of orchard sprays
