摘要: 芒草Miscanthus作为一类可再生能源植物,是解决环境问题和能源供应短缺的有效方法之一。芒草是一类具有根状茎的多年生C4植物,它的最高生物量可达到49 thm-2。综述了芒草的生物学特性、生物量、抗逆性以及水分、氮元素对其生物量及其组成的影响等农艺性状和生理特性,总结了在水分胁迫条件下增施氮肥可以提高芒草的生物量,土壤含水量和耐霜冻能力是提高芒草生物量的2个关键因素,并提出了今后进一步的研究主要是利用现代分子育种手段,选育出抗逆性强、适应不同生态环境条件的高生物量良种品系等。参35Abstract: As a renewable energy crop plant,Miscanthus is one of the effective methods to solve environmental issues and energy shortages. Miscanthus is a typical perennial giant grass in the world and the highest biomass yield can reach 49 thm-2. This paper reviews Miscanthus biological characteristics,biomass yield,stress resistance,effect of water and nitrogen on its biomass and composition. The results show that nitrogen can improve Miscanthus biomass under water stress condition. Water content in the soil and tolerance to frost are two key factors for improving biomass yield of Miscanthus. Further study on breeding genotypes with high biomass,high stress tolerance and adapting to different ecological conditions is needed,which is important for solving the conventional energy shortage and environmental degradation.[Ch,35 ref.]
