Borisova V. Cultivation of European Larch seedlings (Larix) by application of intensive methods under conditions of the Left-bank wooded steppe region of Ukraine

The object is feature of cultivation of planting material of a European larch in hothouses and creation of forest cultures in Left-bank of wooded steppe region of Ukraine.

The results are established laws the development of shoots and annual seedlings of European larch in conditions of the closed ground of Left-bank of wooded steppe region of Ukraine. Tests of a wide spectrum concentrations of growth regulators of plants for a European larch are lead and reaction of seeds and annual seedlings on the applied preparations is investigated. The optimum complex, which provides the greatest yield of standard seedlings from unit of the area, is picked up and includes application of agrostimuline and mineral fertiliser amophos. Influence of a regulator of growth on conservation and further growth of wood cultures is established. A degree of introduction - take root in forestry practice of timber enterprises of the Kharkov region. The results of investigations are applied in forestry.
