Indicators of 50-year-old Siberian cedar pine after decapitation of the crown on the plantation “LEP-1” (suburban area of the city of Krasnoyarsk)
Abstract
The results of studies about the growth and yield of dekapitation trees pine Siberian Cedar at plantation “LEP-1” in the Karaulny territory of the Training and Experimental Forestry SibSU are given. Trim crowns held at the 28-year-old in the biological age trees from 4 up to 10 interstitial site at a height of 1.7 to 2.8 m. Through 9 years trees were subjected to repeated delete 6–8 interstitial site of leading shoots. Control trees aged 50 years reached a height of 8.9 m. The average height of the cropped trees amounted to 7.9 m, which at 12.6 % lower than in control trees. Coefficient variability of cropped trees is higher than of the control trees. The diameter of the trunk control and cropped trees in a 50-year-old has no significant differences. After trimming crown trees are formed mainly by 1–2 leading the escape. Three leading escape was formed at 47 % of the trees, four – in 3 % of the trees. In 2017 g. bumps were formed on 34 % of control trees, 46 %-cropped trees.
