摘　　要：草本能源植物的开发利用研究,在我国农村能源建设中占有十分重要的地位。本文论述了沙打旺不仅适应性强、生长快、产量高,而且周期短,早期能量生产能力高于木本能源植物同期生产能力,能较早的取得生产效益,是解决黄土高原生态系统脆弱地区农村能源问题的一个优良草本能源植物。The study on the exploitation and utilization of grassland ener- gy-plants has been taking very important position in the rural ener- gy construction of our country.Astragalus adsurgens not only with strong adaptability,rapid grouth and high yield,but also wi- th short produtive period,productive capability of energy above woody energy-plants,at the early stage and earlier providing pro- cuctive benefit,was discussed in this paper,and it is a fine grassland energy-plant to solve the lack of rural energy in the zones where the ecosystem is weak in the loess plateau.
