| 摘 要： | 为评价野生禾草作为能源禾草的潜力,在辽宁省范围内对几种野生禾本科草类植物的自然种群特征进行了调查,包括种群的盖度、密度、生物量及其生境中的土壤指标,结果表明虽然在自然条件下芒和狼尾草的生境土壤较贫瘠,但它们却具有生物量高、密度大的特征。野外调查的同时将这几种禾本科草类植物引种到试验园,测定了其在同一栽培条件下的生长速度和光合效率等指标。综合分析表明,狼尾草和芒具有高的产量,而高的净光合速率和生长速度则是其高产的生理生态学基础,它们符合能源禾草的要求,应进行深入研究并加以应用。

| Abstract: | In order to explore the potential of energy grasses,the natural populations features of several wild Poaceae grass in Liaoning Province were investigated,including their population coverage,density,biomass and soil habitats indicators.The results show that under natural conditions,the Miscanthus sinensis and the Pennisetum alopecuroides were in poor soil habitats,but they have a high biomass and density characteristics.We introduced the wild Poaceae grass to the plant garden to study their growth rate and p... |
