杨树短轮伐期矮林培育国内外研究进展

Research Progress in Silviculture of Poplar Short Rotation Coppices

短轮伐期矮林作为一种可再生能源原料生产方式,其产品(如生物质成型颗粒燃料、生物乙醇等)可以替代日益匮乏的化石燃料,因此受到广泛关注。文中介绍了国内外杨树短轮伐期矮林培育研究进展情况,主要包括良种选育、营造技术、密度控制、轮伐周期、施肥技术、病虫害防治、收获技术及矮林收获物的化学成分等方面,旨在为今后我国研究和发展杨树短轮伐期矮林提供思路和方法。

Short rotation coppices have aroused wide concerns as a means to produce renewable energy materials, as their products, such as biomass particle fuel, bio-ethanol, can substitute decreasing fossil fuel. The paper introduced the research progress at home and abroad in poplar short rotation coppices in relation to improved species breeding, silviculture technology, density control, rotation, fertilization technology, diseases and pests control, harvesting technology and chemical components of coppice harvests. The study was aimed at providing ideas and approaches for China to study and develop ooolar short rotation connices.
