Sapling extractor for mechanized planting

Abstract

Plants grown by at least double transplanting, root cutting or transplanting into a packing, or a combination of these operations, with an above-ground partfrom 121 cm to 250 cm high and shaped crown. Artificial regeneration of forest stands is carried out on an area of approx. 20 thousand ha per year, in the Czech Republic. To ensure such tasks of artificial forest regeneration and afforestation, domestic forest nurseries ship to customers around 120-140 M pieces of planting materiál of forest trees. The assertion of saplings from seedling forest in maturity age stands extends the spectrum of options for introducing deciduous trees into mountain conifer stands and enables a combination of planting materiál of normál and large dimensions, where the weaknesses of one technology are secured by another technology. Especially in extreme climatic and natural conditions, their usage can achieve significantly higher survival and thus lower losses during afforestation. Most of the thick skeletal roots should be formed by the sapling only after its planting in the forest stand, which the risk of root deformations is significantly reduces.
