EXPERIENCE OF CREATION AND FORMATION OF OAK-LINDEN PLANTINGS CULTIVATIONS IN THE FORESTS OF THE ZHORNOVSKOY EXPERIMENTAL FOREST BASE, THEIR CONTEMPORARY STATE
In the article are given the materials about creation and formation of the mixed cultivations of oak with the linden under the conditions оf Zhornovskoy experimental forest base. The results of longstanding observations of their increase are given, is given estimation to their state at present and further prospects for the cultivation of the cultivations of oak with the linden are examined. Despite the favorable conditions for the location of mixed crops with the mixing scheme 3 rows of oak 1 row of linden (grow according to the 1st class of bonitet) and the advantage of oak in planting, by the age of 23 the stock of linden per hectare is almost 30% higher than the oak stock. Also, the average height of the linden exceeds the oak by 2.1 m, the average diameter - 2.6 cm. Increase the productivity and stability of mixed oak plantations contribute to the undergrowth or the second layer of linden. Due to the limitation of linden growth "landing on the back", it was possible to form a two-level oak-lime plantation of qualitative composition. In different years of measurement, the predominance of oak in relation to lindens at medium altitude varies from 2.1 m to 10.5 m, and on average diameter from 1.4 cm to 11.5 cm. In such plantations, the linden completely fulfills its silvicul-tural purpose.
