太行山低丘陵区薪柴类能源林树种选择

Tree species selection of firewood energy forest in the hilly area of Taihang mountain

对太行山区14种常见薪柴类能源树种进行了组织含水量、生长性状、干质量热值、抽提物及灰分等指标测定。结果表明:抗旱性较好的树种有荆条、山杏、山桃、黄栌、五角枫、丁香及刺槐;生物生长量比较大的为刺槐,其次是构树、火炬树、黄栌等;燃烧性较好的树种有刺槐、荆条、紫穗槐、山桃、丁香、国槐、五角枫等。综合不同树种单株产生的能量及可燃性比较,在太行山低山丘陵区营造燃料类能源林首先应考虑的是刺槐、荆条、山桃和紫穗槐等树种。

In this study,tissue water content,growth traits,dry weight calorific value,extract and ash content of14 common firewood energy tree species were determined in Taihang Mountains.The results showed:the tree species with better drought resistance were:Vitex negundoL.var.heterophylla(Franch.) Rehd.,Armeniaca sibirica(L.)Lam,Amygdalus davidiana(Carrière)de Vos ex Henry,Cotinus coggygriaScop.,Acer elegantulum Fang et P.L.Chiu,Syringa amurensisRupr.,Robinia pseudoacaciaLinn..The tree species with relatively larger biomass increment were:Robinia pseudoacacia Linn.,followed by Broussonetia papyrifera(Linn.)L’Hér.ex Vent.,Rhus typhina Nutt,Cotinus coggygria Scop.,etc.The tree species with better combustibility were:Robinia pseudoacacia Linn.,Vitex negundo L.var.heterophylla(Franch.) Rehd.,Amorpha fruticosaLinn.,Amygdalus davidiana(Carrière) de Vos ex Henry,Acer elegantulum Fang et P.L.Chiu,etc.Through a comprehensive comparison of energy and flammability of different tree species,the tree species of firewood energy forest plantation should first choseRobinia pseudoacaciaLinn.,Vitex negundoL.var.heterophylla(Franch.) Rehd.,Amygdalus davidiana(Carrière)de Vos ex Henry andAmorpha fruticosaLinn..
