Uosialapio klevo optimalūs naikinimo metodai

Abstract

Tyrimai atlikti Neries pakrantėje, Jonavos rajone esančioje Svilonių girininkijos teritorijoje. Tyrimo tikslas – rasti efektyvų uosialapio klevo naikinimo būdą, naudojant herbicidą ,,Glyfos Supreme 450 SL“. Pagrindinis uždavinys – nustatyti tinkamiausią uosialapio klevo atžalų purškimo laiką ir preparato koncentraciją. Tirta dviem etapais: uosialapiai klevai išpjauti ir kelmai tepti cheminiu preparatu, antruoju etapas – atžėlusios atžalos purkštos skirtingos koncentracijos cheminiu preparatu skirtingais vasaros mėnesiais. Atlikus tyrimą nustatyta, kad naikinant uosialapį klevą, tepant kelmus herbicidu, 1 % ir 2 % tirpalo koncentracijos neveiksmingos. Antrame etape nustatyta, kad atžaloms naikinti veiksminga mažiausiai 50 % . pasirinkto herbicido koncentracija

Investigations were carried out on the coast of the Neris, in the area of Sviloniai forest district located in Jonava district. The aim of the study was to find an effective way of destroying ash-leaved maple using herbicide ,,Glyfos Supreme 450 SL“. The main task is to determine the optimal time of spraying the sprouts and concentrations of the herbicide. The study was carried out in two stages: the first stage was the cutting of ash-leaved maples and the stump oiling with a herbicide; in the second stage – regrowed sprouts were sprayed with a different concentrations of the herbicide, spraying works performed in different summer months. The study showed that in the case of the eradication of the ash-leaved maple, oiling stumps with the herbicide, concentrations of 1% and 2% solution are not effective. At the second stage of the investigation, it was determined that at least 50% concentration of the selected herbicide is effective to destroy the sprouts
