运用煤中植物残体分析的方法研究了乐平煤的成煤植物,认为乐平煤的主要成煤植物中树蕨辉木类最重要,其次是鳞木类和裸子植物.探讨了乐平煤中树皮体的起源,认为树皮体中的大部分不是来源于树蕨辉木的小根外部皮层中的厚壁组织,也不是来源于鳞木类或裸子植物的周皮,而可能是来源于一种植物的特殊组织,这种植物推测为一种大羽羊齿类植物的根———刺根茎Rhizomopsisgemmifera,而这种特殊组织的性质目前还不清楚,可能属于周皮组织,也可能属于其他组织,有待于今后进一步研究.
Based on the analysis of plant residues in coal, the coal-forming plants of Leping coal were studied. It is considered that the main species of the tree fern in the coal-forming plant of Leping coal is the most important, followed by the scales and gymnosperms. The origin of the bark body in Leping coal is discussed. It is believed that most of the bark body is not derived from the thick-walled tissues of the small root outer cortex of the tree bark, nor from the periderm of the scales woods or gymnosperms , But may be derived from a plant’s special tissue, this plant is presumed to be a large feather fern roots --- rhizomopsisgemmifera Rhizomopsisgemmifera, and the nature of this particular tissue is unclear, may belong to the skin Organizations may also belong to other organizations to be further studied in the future.
