昆明地区常见壳斗科植物鲜叶的燃烧性

Combustibility of Fresh Leaves of Common Species of Fagaceae in Kunming, Yunnan Province

为了比较壳斗科内不同植物的燃烧性,以高山栲(Castanopsis delavayi)、滇石栎(Lithocarpus dealbatus)、毛脉高山栎(Quereus rehderiana)、木姜叶柯(L.litseifolius)、长穂高山栎(Q.longispica)、滇青冈(Cyclobcdanop sisglaucoides)6种昆明地区常见的壳斗科植物鲜叶为研究对象,测定了每种鲜叶的单位面积质量、含水率、灰分含量、抽提物含量、热值5个理化性质指标,用自行设计的试验装置进行6种鲜叶燃烧试验并计算了其燃烧速率和损毁程度。结果表明:6种壳斗科植物鲜叶在纯氧中的损毁程度都达到了100%,且燃烧相对速率较快,均属于易燃植物,鲜叶的燃烧性与理化性质和单位面积质量有关。

In order to compare the combustibility of species of Fagaceae, fresh leaves of Castanopsis delavayi, Lithocarp us dealbatus, Que reus rehderiana^ Lithocarpus litseifolius, Quercus longispica, Cyc lob alanops is glaucoides were sampled and their physical and chemical properties, including mass per unit area, moisture content, ash content, extract content and calorific value, were tested. At the same time, the fresh leaves combustion test was conducted by a self-designed combustion test device and the burning rate and damage degree of fresh leaves were calculated. The results showed that the damage degree of the fresh leaves of 6 species of Fagaceae in pure oxygen reached 100%, and the relative burning rate was fast. The 6 species of Fagaceae were the flammable plants, and flammability of fresh leaves was closely related to its physical and chemical properties and mass per unit area.
