为促进中国边际土地草本能源植物种植与生物质原料生产,基于京郊边际土地草本能源植物规模化种植的实践,从生产潜力、生物质品质、生物质利用潜力、生态效应等4个方面对荻的应用潜力进行了分析评价。结果表明:荻在京郊挖沙废弃地上的生产潜力为2.31t/hm2,达到京郊耕地条件下的8.41%,生物质品质优良,其标准煤折算当量、沼气产量、纤维素乙醇产量分别为1.42t/hm2、289.99m3/hm2、0.59t/hm2,分别达到京郊耕地条件下的8.38%、8.37%、8.15%,生态效应明显。荻在边际土地上具备良好的应用潜力。
In order to promote the cultivation of herbal energy plants and the production of biomass in the marginal land in China, based on the practice of large-scale cultivation of herbaceous plants on the marginal land in the suburbs of Beijing, from the aspects of production potential, biomass quality, biomass utilization potential and ecological effects, The potential of the application was analyzed and evaluated. The results showed that the potential productivity of dioscorea zizhnophylla was 2.31t / hm2 in the dugout lands in the suburbs of Beijing, reaching 8.41% of the cultivated land in the suburbs of Beijing. The quality of biomass was good. The equivalent conversion of standard coal, biogas output and cellulosic ethanol production were 1.42t / hm2, 289.99m3 / hm2 and 0.59t / hm2, respectively, which reached 8.38%, 8.37% and 8.15% respectively in the cultivated land in the suburbs of Beijing. The ecological effect was obvious. Di in the marginal land with good potential applications.
