在全球性能源紧缺和我国能源植物大规模种植困难等大背景下,优质、充足的原料供应已成为制约生物质能源产业发展的主要限制因素。在确保能源植物高效生产和克服“与粮争地、与人争粮”现实的同时,挖掘我国边际土壤高产高效生产能源植物的土地优势和增产潜力。通过筛选评价适宜西北干旱地区高抗逆的新型能源植物种类,开发应用能源植物与粮经作物间套作栽培技术,实现新型能源植物对逆境资源的高效利用和可持续规模化种植,提高能源植物的生产力和优化能源物种的区域配置,增加土地产值和农民收入,缓解能源紧缺,达到经济、生态和社会效益多赢,为我国能源和粮食安全提供技术支撑。
Under the background of global energy shortage and the difficulty of large-scale cultivation of energy plants in China, the supply of high quality and sufficient raw materials has become the main limiting factor restricting the development of biomass energy industry. While ensuring the efficient production of energy plants and overcoming the reality of competing for food with the grain, we should excavate the land superiority and yield potential of the high yield and high efficiency energy-producing plants in the marginal soil of our country. By screening and appraising the types of new energy plants suitable for high resistance in the northwestern arid region, developing and applying intercropping cultivation techniques between energy plants and grain-and-cash crops so as to realize the efficient use of new energy plants and sustainable large-scale cultivation of adversity resources, Productivity and optimize regional allocation of energy species to increase land output and farmers’ income, ease energy shortage and achieve win-win economic, ecological and social benefits and provide technical support for China’s energy and food security.
