RESULTS OF INCREASED SEEDLINGS PER UNIT AREA IN THE ROBINIA PSEUDOACACIA SPECIES
Journal Title: Natural Resources and Sustainable Development - Year 2016, Vol 6, Issue 1
Abstract
Acacia (Robinia spp), as main genus in the forestry culture, presents special importance in our country, it distinguishes itself by a particularly dense wood used both in constructions and as fire wood. Aside from these two uses acacia also distinguishes itself by multiple other uses, such as: it is the most melliferous forest tree in our country, it can be successfully used in stabilising slopes respectively landslides, stabilising sand dunes in agricultural regions such as those from Valea lui Mihai in Bihor county, in the plain area for the formation of wind protection forest curtains of agricultural lands, hunting grounds. At global level it joins the other species of plants capable of storing atmospheric carbon in trunk, branches and root and the soil on which it is cultivated is also enriched by the input of atmospheric nitrogen which the plant fixates in the soil via roots, forming nodosities of the Azotobacter type. It is known that in Romania the acacia generally prefers the warm regions, with gentle, long autumns, safe from early frosts. The specialized literature as well as the experience of the past years confirmed the fact that acacia is a capable and available species, a species which presents impressive advantages from the standpoint of biomass production in agroforestry systems. For the forestation of a land surface, when we use the general planting scheme of 2x1(m), a number of 5000 plants/ha is necessary, upon establishing the agroforestry cultures for the production of wooden biomass this number of plants grows proportionally based on the adopted planting scheme, so that the final number of plants/ha used upon establishing such a culture doubles in the majority of cases. Moreover one presents in the paper several legislative aspects regarding the commercialization of the reproductive forestry materials.
