我们从1984年开始,经过6年的试验,对10个乔木树种的生物量、生物量在树木各成份间的分配,枯枝落叶量、燃烧值等进行了测验分析,研究了树种、造林密度、密度同树种的组配形式对树种生物产量的影响。综合多指标分析,筛选出酸性紫色土区优良的薪炭林树种马尾松、麻栎和刺槐,一般树种蓝果、女贞。试验概况试验地位于东经110°01′20″,北纬27°42′02″,距离麻阳县城40公里,海拨高210-260米,丘陵属中亚热带湿润性季风气候区。
We started from 1984, after 6 years of experiment, the biomass of 10 tree species, the distribution of biomass in the tree components, the amount of litter, the burning value were tested and analyzed the tree species, planting density , The density of tree species with the form of the tree species on biological yield. Based on the comprehensive multi-index analysis, Pinus massoniana, Quercus acutissima and Robinia pseudoacacia were selected as excellent firewood tree species in acidic purple soil area. The experimental site of the experiment is located at 110 ° 01’20 “east longitude and 27 ° 42’02” north latitude. It is 40 km from Mayang County and 210-260 meters above sea level. The mound belongs to the subtropical humid monsoon climate zone.
