生物柴油树种无患子研究进展

Research progress of biodiesel tree Sapindus mukorossi

无患子(Sapindusmukorossi)是我国重要的生物柴油能源树种,其果实丰富的含油量、果皮中的皂苷以及木材的优良价值使其作为一个多功能树种受到高度重视,但规模化、集约化栽培无患子还刚刚起步。笔者从种质资源、良种选育、苗木培育、栽培技术和加工工艺等方面对无患子国内外研究现状进行了综述,发现缺乏良种、苗木繁育技术落后、栽培技术落后及油料成本高等是无患子产业发展的瓶颈所在,并分析提出了今后研发的重点领域和方向。

Because of the abundant biodiesel and saponin in the seed,Sapindusmukorossi has attracted much attention in China as a source of non-food plant biomass fuel.The timber of Sapindus also has important economic value.However,the study on cultivation techniques of Sapindus is still at the very beginning.This review summarizes the current knowledge on the potential biodiesel tree Sapindus,including germ plasm resource,variety breeding,seedling cultivation,cultivation techniques and processing technology.The conclusion shows that the lack of superior varieties,backward seeding cultivation techniques and high-cost are the main problems impeding the progress of Sapindus industry.
