The living condition of spruce in forest cultures in the Verkhovazhsky district of the Vologda region was studied depending on the forest growing conditions. According to the forestry zoning, the area of location of the experimental facilities belongs to the Baltic-Belozersky taiga district. Harvesting of timber at the forest crop sites was carried out in 2008 by small complex teams using TDT-55 crawler tractors. Planting seedlings in 2010. was carried out in the reservoir by hand, under the sword of Kolesov. The distance between the seats in the rows is 0.5 m, between rows – 4 m. The initial density of forest crops is 3000 specimens / ha. Our study showed that at present, active regeneration of aspen and birch takes place on crop areas, which have a negative competitive impact on the growth and development of planting of spruce. It is established that spruce in forest cultures at the initial stages of the formation of the future stand grows most actively, has the greatest growth and greatest safety in spruce forests, and grows somewhat weaker and gives a slow growth in the bilberry spruce forest. After 6 years, the maximum growth of spruce is noted already in the bilberry spruce forest. In these forest-plant conditions, the spruce has the greatest growth in height and the longest length of the needles, the maximum length of the crown along the trunk. According to the results of the conducted study, it is unambiguously concluded that for the formation of a full spruce or spruce-deciduous stand by the age of felling, it is necessary fi rst of all to take into account the conditions of the site of occurrence, at the subsequent stages of growth and development of artifi cially created plantations, an important condition is already timely and competent (with observance of all silvicultural requirements) carryingout agrotechnical and silvicultural care. Изучено жизненное состояние ели в лесных культурах в Верховажском районе Вологодской области в зависимости от лесорастительных условий. Согласно лесохозяйственному ...
