Abstract

The issue of accelerated forestry plantation with high-quality wood using the best soils in terms of productivity, fertilizers, and intensive treatment has become quite relevant due to increased demand for forestry products and higher requirements for environmentally friendly use of forest resources. This paper presents the results of a study on the impact of various techniques for treating coniferous plantations, including thinning, fertilization, and herbicide processing, on wood quality key indicators. The paper examined the wood density, correlation of early and late wood zones, and the cell wall thickness for 38-year-old pine trees grown on the sample plots of Siversky leskhoz (Leningrad region, Gatchinskiy district) at different treatment and density control techniques. It has been established that the highest basis density of wood corresponds to the samples grown at the density variant of 1 t/ha and double herbicides treatment, and the lowest basis density value was recorded at the option of 4 t/ha with combined treatment. It has been shown that the increase of width index for early wood is influenced by the lower density of 1 t/ha and one-time herbicide treatment, for late wood – by the lower density of 1 t/ha and repeated treatment with herbicides. The increase in average cell wall thickness for early and late wood is observed when the density increases up to 4 t/ha and double herbicides treatment. The results obtained provide a valuable scientific contribution to general forestry knowledge and have practical value in plantation forestry.
