Установлено, что тип целевых добавок и значения концентраций водорастворимых полимеров в составах для обработки могут оказывать существенное влияние на физико-химические свойства композитов и потерю влаги корневыми системами сеянцев. Приведены оптимальные составы композиционных полимерных материалов для защиты корневых систем ряда хвойных пород от иссушения.</p></abstract><trans-abstract xml:lang="en"><p>The results of the development of composite polymer materials for processing root systems of seedlings in order to increase the survival rate of forest crops are presented. It has been established that the type of target additives and the concentration of water-soluble polymers in the compositions for processing can significantly affect the physicochemical properties of the composites and moisture loss by root systems of seedlings. The optimal compositions of composite polymer materials for protecting the root systems of a number of conifers from drying out are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композиционные полимерные материалы</kwd><kwd>хвойные породы</kwd><kwd>корневые системы</kwd><kwd>иссушение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composite polymeric materials</kwd><kwd>conifers</kwd><kwd>root systems</kwd><kwd>desiccation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Different hydrocolloids as bread improvers and antistaling agents / A.
