三种能源草,耐贫瘠,适合种在沙荒、废弃、污染等土地上,是最受青睐的新兴能源植物。北京草业与环境研究发展中心筛选出3种能源草:柳枝稷、芦竹和荻。目前已在密云、延庆、大兴和昌平等地试种了3000亩。能源草富含碳氢化合物,炭活性高,热值高,污染物少,可有效减轻温室效应,还可固沙、改善土壤、绿化荒地。秸秆等生物能源存在生态风险,能源草则不存
Three kinds of energy grass, barren, suitable for planting wasteland, waste, pollution and other land, is the most popular emerging energy plants. Beijing Pratacultural and Environmental Research and Development Center screened three kinds of energy grass: switchgrass, Arundo donax and Di. Has been in Miyun, Yanqing, Changxing and Changping, and other places planted 3,000 acres. Energy grass is rich in hydrocarbons, high carbon activity, high calorific value, less pollutants, can effectively reduce the greenhouse effect, but also sand fixation, soil improvement, green wasteland. Bioenergy such as straw has ecological risk, while energy grass does not exist
