Abstract

The paper presents the results of the studies on growing Gmelin larch seedlings (L?rix gm?linii Rupr) in the Trans-Baikal Territory. We have established that the best way to prepare the seeds for sowing is keeping them under the snow for 2 months and necessarily treating them with a 1 % potassium permanganate solution for 3 hours before sowing. Good results are obtained at sowing the seeds in mid-May in 5–6 cm wide sowing lines. The seeding rate is 0.4 g per running meter and the direction of the sowing lines is north-to-south. In dry years, shoots are well preserved if mulched with sawdust up to 0.5 cm thick and regularly (each 4–5 days) watered by 100–120 m3/ha. To receive the planned yield of standard seedlings one needs to introduce organic and mineral fertilizers based on the chemical analysis of soil in the nursery. The developed agricultural method of growing Gmelin larch seedlings allowed us to give up the expensive shading of crops, save 10–14 kg/ha of seeds and increase the yield of two-year standard seedlings by 40–50 %.
