GROWING SEEDLINGS OF SIBERIAN LARCH WITH A CLOSED ROOT SYSTEM TO CREATE RELATIVELY FIRE-RESISTANT FOREST PLANTATIONS

The article provides an analysis of soil germination, growth dynamics of seedlings, biomass of aboveground and underground parts of Siberian larch (Larix sibirica) with a closed root system (ZKS) grown by sowing in cassettes. There are 7 variants of the experiment on three types of substrates. Pre–sowing treatment of seeds was carried out with Borogum-M, Phytozont, Giberelon + Kornevin, Kornesil, Ultramag Boron. Peat substrates were fueled with starter fertilizers, mycorrhiza and soil microflora. One of the variants of the experiments was tested by adding agroperlite, in order to reduce the density of the substrate. A variant of the intensified seedling production is proposed to create relatively resistant to burning processes of plantings.
