Growth of common pine crops within the boundaries of the Arkhangelsk forestry of the republic of Bashkortostan
The paper studies the features of growth of common pine crops in the conditions of Arkhangelsk forestry and the assessment of the prospects for the creation of these forest crops in the future. It is established that the plantings are mixed and pure cultures, aged 31 to 33 years. Average elevation at all test sites is about 9.0 m, and the average diameter of about 8.4 cm species composition, represented by the pine. Class of site class ranges from II To. The completeness of the stand 0.6. It is determined that the magnitude of the diameters of the trunks of Scots pine at various plots vary of 8.07±of 9.67 cm to 0.01±0,09 cm Average trunk diameter of cultures of a pine change of 8.07±of 9.67 cm to 0.01±0,09 see the kurtosis is in the range from 0.57 to 27,40 units, it is positive. The asymmetry is both positive and negative in different sample areas (from -2.90 to 0.54), which confirms the skewed curve of the trunks distribution to the left, in contrast to the normal distribution. The accuracy of the experiment is in the range of 0.18 to 0.96%. The height of the stems varies from that of 8.45 m of 10.38 m. the Kurtosis in the range from -0,29 to -0,82 units, negative. There is a flat-top distribution of trunks at altitudes. The asymmetry is mostly negative. Accuracy of experience-0.28-1.04%. The growth in height of the lead of culture in the fresh SprutCAM in SkyTeam forest type. in terms of diameter at breast height is also a leader of culture in the fresh SprutCAM in SkyTeam forest type. the best indicators of growth and development show crops growing in flat terrain. In General terms snatiago forest type and fresh SprutCAM culture of Scots pine grow better than grass forest and fresh subgame.
