Abstract

It is noted that plant roots make a significant contribution to the formation of technozems during self-overgrowing of the technogenic substrate. The rate of decomposition of a mixture of fine roots (<0.5 mm thick) of meadow arbuscular mycorrhiza species (AM) in comparison with forest ecto mycorrhiza species (EM) in the ash substrate from the power station was studied in a 150-day experiment in the laboratory. Differences in the rates of decomposition of root mixtures, as well as in carbon (C) and nitrogen (N) content before and after decomposition in different variations of the experiment, have been revealed. AM species have higher losses of biomass, nitrogen, and carbon in contradistinction to ЕM species.

电厂垃圾场灰分基质中草甸和森林植物根系的分解：室内实验

摘要

值得注意的是，植物根系在技术基质的自我过度生长过程中对技术瘤的形成做出了重大贡献。在150天的实验中，研究了电厂灰烬基质中草甸丛枝菌根（AM）细根（<0.5 mm厚）混合物与森林菌根菌种（EM）的分解速率。在实验室里。在不同的实验变体中，分解之前和之后的根混合物分解速率以及碳（C）和氮（N）含量的差异已经被揭示出来。与ЕM物种相反，AM物种的生物量，氮和碳损失更高。
