Pruning in poplar plantations by mechanized device Stihl HT-75 (original) (raw)

2009, Glasnik ?umarskog fakulteta

The effects of branch pruning device Stihl HT-75 were researched on sample plots in FA Kupinovo and FA Klenak, in poplar plantations of Populus?euramericana 'I-214', Populus?euramericana 'M1' and Populus deltoides of different planting spaces and different ages. The analysed factors were: pruning method, site conditions, number of pruned branches, pruning height, branch diameter, etc. Time measurement was performed by the flow method, and the required number of measurements was calculated by variation statistics. The results of the analysis of variance show the statistical significance of the differences between pruning times of different clone species, different planting spaces and different plantation ages. The results of the analysis of variance and statistical tests show that there are no statistically significant differences between the average time of poplar pruning in plantations of the same age and different planting spaces. The correlation of branch pruning ...
