The purpose of the study was to examine a century of
experience of growing of forest cultures of the
Siberian stone pine in forest conditions in the region of
the Middle Volga. To achieve these objectives, we
have investigated old growth culture of Siberian stone
pine in the conditions of fresh oak forests in the
territory of Rootka forestry of the Mari El Republic.
Culture of Siberian stone pine was planted after
continuous tillage. The distance between rows was 2,5
m, step landing – 1,0 m. The site was divided into five
options, depending on variations in the width of
planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m,
V - 32 m). The studies have shown that the Siberian
stone pine trees, regardless of the variant, are
characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It
can be noted that in the 100-year-old age, the average
height of trees reaches of 28,7 m, an average diameter
of 49,8 cm. Stock of forest reaches 795,3 m3
/ha. Best
annual increase is observed in growing cultures of
cedar in the wings with a width of 40 m and is 7,95-of
7,93 m3
/ha. Based оn the research, we have concluded
that Siberian stone pine should be recommended for
introduction into the zone of coniferous-broadleaved
forests of the Middle Volga region. When creating
crops, it is necessary to use larger seedlings and plant
density is not more than 1,0 thousand pieces/ha, and
the width of the planting strip shall be not less than
40,0 m.
