【摘要】 杂交狼尾草(Pennisetum americahum×P.Purpureum)系美洲狼尾草(P.americahum)与象草(P.Purpureum)的种间杂交种,是多年生高大C4草本植物,已作为造纸、饲料原料等被广泛应用,是中国有前景的非粮能源植物之一。笔者以非粮生物质原料生产和生物质转化利用为中心,针对杂交狼尾草的生物学特征、遗传特性与良种选育、产量、品质特征和生物质转化利用、生态适应能力和生态效益、栽培及管理技术等方面的研究进展和存在的问题进行了详细阐述,并展望杂交狼尾草作为能源植物的研发前景。认为虽然杂交狼尾草存在对土壤条件要求高、在北方地区不能越冬等缺点,但较其他能源植物具有显著的产量优势,在条件较好的边际土地和污染农田上具有广阔的利用前景。更多还原

【Abstract】 Hybrid pennisetum(Pennisetum americahum × P. Purpureum) is an interspecific hybrid between Pennisetum americahum and Pennisetum Purpureum, which is C4 perennial tall grass and widely used asmaterial in papermaking and feedstuff, it is also one of the energy crops with prospect in China. The authorsfocused on the production of non-grain biomass material and biomass transformation and availability,elaborated the research process of hybrid pennisetum on the aspects of biological characteristics, hereditarycharacteristics, breeding, yield, quality characteristics and biomass transformation and availability, ecologicaladaptive capacity, ecological benefits, cultivation and management technology, and the prospect of hybridpennisetum used as energy crop was also proposed. Although hybrid pennisetum had disadvantages such ashigh demand on soil and could not overwintering in northern area, it had significant yield advantage over otherenergy plants, it had wide prospect on marginal land and polluted soil with better conditions.更多还原
