Исследования проводились с 2021 по 2023 гг. Расчеты запасов фитомассы проведены с использованием рассчитанных на основе модельных деревьев аллометрических уравнений. Вес одного среднего дерева в абсолютно сухом состоянии варьирует для сосны обыкновенной от 14 до 22 кг, для сосны скрученной – от 23 до 38 кг на одно дерево. К 20-летнему биологическому возрасту в надземной фитомассе культуры сосны скрученной накапливают от 46 до 76 т/га, сосны обыкновенной – от 27 до 44 т/га органического вещества. Показано, что по массе стволов в экспериментальных культурах, заложенных на сосновой вырубке и сельскохозяйственных землях, сосна скрученная максимально превышает сосну обыкновенную по сравнению с другими участками (рекультивированные карьеры). В целом результаты исследования показали, что превышение надземной фитомассы культур сосны скрученной по сравнению с сосной обыкновенной составляет от 25 до 45% на различных участках экспериментальных культур. Структура надземной фитомассы у исследуемых пород имеет схожий характер. Полученные результаты могут использоваться для пополнения базы данных по продуктивности лесных культур и для оценки депонирования углерода искусственными насаждениями в средней тайге.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to comparison the phytomass of two tree species: lodgepole pine (Pinus contorta Dougl.), native to North America, and local Scots pine (Pinus sylvestris L.) in experimental plantations of the Syktyvkar, Koygorodsky, Kortkerossky and Ukhta areas of the Komi Republic, established in 2004–2006 on 4 sites of different forest categories. The studies were conducted from 2021 to 2023. Calculations of phytomass reserves were carried out using model trees for allometric equations. The weight of one tree in an absolutely dry state varies for Scots pine from 14 to 22 kg, for lodgepole pine – from 23 to 38 kg per tree. By the age of 20 years, the aboveground phytomass of lodgepole pine trees accumulates from 46 to 76 t/ha, and that of Scots pine from 30 to 44 t/ha of organic matter. It is shown that by trunk mass in experimental plantations planted on pine clearings and agricultural lands, lodgepole pine maximally exceeds Scots pine compared to other areas (reclaimed quarries). In general, the results of the study showed that the excess of aboveground phytomass of lodgepole pine plantations, compared to Scots pine, is from 25 to 45% in different areas. The structure of aboveground phytomass of the species studied has a similar pattern. The results obtained can be used to replenish the database on the productivity of forest crops and to assess carbon deposition by forest plantations in the middle taiga.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>искусственные насаждения</kwd><kwd>сосна скрученная (Pinus contorta Dougl.)</kwd><kwd>аллометрические уравнения</kwd><kwd>фитомасса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>allometric equations</kwd><kwd>forest plantation</kwd><kwd>lodgepole pine (Pinus contorta Dougl.)</kwd><kwd>phytomass</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Института биологии Коми НЦ УрО РАН, тема «Cредообразующая роль и продуктивность лесных и болотных экосистем европейского северо-востока России» (№ 125020501547-8).
