摘要

技术),Mytishchi, e-mail:(Betula pendula Roth.)属于弥散维管树种,在木材样品上相对难以区分。这导致在俄罗斯平原用树木年代学方法对该物种的研究相对较少。同时,在莫斯科和莫斯科地区的游憩林和林地公园条件下,该树种是最重要的造林树种之一。树木年代学诊断在这些条件下径向生长的特征对森林科学理论和林业实践都有很大的兴趣。本文报道了莫斯科地区多莫杰多沃森林桦树的年代学调查结果。在进行研究的基础上,确定了所有模型展台均由六年级组成。4个试验样地的树木,尽管在参与林下植物区系组成和活地被植物区系组成时所形成的植物群落存在差异,但桦树的生长发育条件相似。树木气候分析表明,6月和7月的缺水是生态生长的主要限制因素,会导致桦树生长不良和状况不佳。一般来说,特定单项气象参数的变率与年轮的变率之间没有强烈而明确的联系,而这种联系在非极端植被条件下的人工林中是典型的。为改善人工林条件,促进径向生长,加速伤口过度生长和树干机械损伤,建议在6、7月份降水量明显低于平均值的年份进行浇水

RESULTS OF DENDROCHRONOLOGICAL STUDIES IN BIRCH STANDS AT THE DOMODEDOVO FORESTRY OF THE MOSCOW REGION
Technology), Mytishchi, e-mail: ( Betula pendula Roth.) belongs to disseminated vascular tree species and is relatively poorly distinguishable on wood samples. This led to relatively little research of this species on Russian plain by dendrochronological methods. At the same time, in conditions of recreational forests and woodland parks of Moscow and Moscow region this specie is one of the most important forest-forming species. Dendrochronological diagnosis for features of radial growth in these conditions has a great interest for forest science theory as well as for forestry practices. The results of dendrochronological investigations in betula satnds from Domodedovo forestry of Moscow region are disclosed in this article. On the basis of the conducted studies it was established, that all model stands consist of Vi age class. The trees of all four test plots, despite the presence of differences in the phytocenoses formed with their participation in the floristic composition of the undergrowth and live ground cover, are characterized by similar conditions for the growth and development of birch trees. Dendroclimatic analysis showed that water scarcity in June and July is the main limiting factor of ecological growth, which can cause poor growth and poor condition of birch trees. in general, there are no strong and unambiguous connections between the variability of specific individual meteorological parameters and the variability of annual rings, which is typical for plantations in non-extreme conditions of vegetation. To improve the condition of plantations, to stimulate radial growth in order to accelerate the overgrowing of wounds and mechanical damage to trunks, watering trees in June and July can be recommended in those years when the amount of precipitation over these months will be significantly lower than the average
