【摘要】 能源作物的种植是生物质能源发展的基础,本文就多年生草本木质纤维素能源作物研究进展,及该类植物在我国北方的资源潜力进行述评。综合生物质产量水平、水分和养分利用、生态影响和生产成本等因素,普遍认为多年生草本纤维素植物是边际土地上最有潜力的能源作物。经过二十多年的筛选研究,芒草(Miscanthus spp．)、柳枝稷(Panicum virgatum)、草芦(Phalaris arundinacea)和芦竹(Arundo donax)被认为是较理想的能源作物。由于我国人均土地资源严重不足,利用北方干旱、半干旱边际土地发展多年生草本木质纤维素能源作物具有很大潜力。北方地区有非常丰富的植物资源,芨芨草(Achnatherum splendens)、远东芨芨草(Achnatherum extremiorientale)、羽茅(Achnatherum sibiricum)、拂子茅(Calamagrostis epigejos)、青紫披碱草 (Elymus dahuricus)、乾宁狼尾草(Pennisetum qianningense)等22种耐旱能力强的植物是有前景的多年生草本木质纤维素能源植物。建议研究这些植物在干旱、半干旱生态区的生物质生产力、光合作用特征、水分和养分利用效率及品质等特性,筛选适合我国北方边际土地栽培的能源作物种类。更多还原

【Abstract】 Energy crop plantation will play an important role on biomass energy production.In this article,progress of perennial herbaceous lignin cellulosic energy crops is overviewed and the resource of this type plants in North China is evaluated.It has been recognized that perennial herbaceous lignin cellulosic energy crops are the most promising biomass crops in marginal lands of the world,because of the high biomass yield,high water and nutrient use efficiencies,friendly ecological effects and low cultivation cost.According to numerous screening studies,miscanthus (Miscanthus spp.),switohgrass (Panicum virgatum),reed cannarygrass (Phalaris arundinacea),giant reed (Arundo donax) have been found to be the most potential species for biomass energy production.Due to serious limitation of arable land resources in China,it is expected that perennial herbaceous lignin cellulosic crops are suitable to be developed in the North China,where there are plenty of marginal land resources with arid and semi-arid climates.Plant resources are rich in the North China,Twenty two drought resistant perennial herbaceous plants species such as Achnatherum (Achnatherum splendens),Far East Achnatherum (Achnatherum extremiorientale),Siberian Achnatherum (Achnatherum sibiricum),Chee Reedgrass (Calamagrostis epigejos),Violet Wildryegrass (Elymus dahuricus),Pennisetum (Pennisetum qianningense) are discussed as potential biomass energy crops native to the North China.It is suggested to screening the most adapted biomass species in the North China from the potential resources according to the adaptability,biomass yield,photosynthesis characteristics,water and nutrient use efficieneies,and quality for energy.更多还原
