| 摘 要： | 能源草是目前最具发展潜力的生物质资源之一,为获得能源草在华北地区边际土地种植过程中肥料效应方面的基础数据,在京郊挖沙废弃地上开展了能源草柳枝稷(Panicum virgatum L.)、荻(Triarrhena sacchariflora (Maxim.) Nakai)和芦竹(Arundo donax L.)的氮肥效应试验。结果表明:氮肥对边际土地上种植的3种能源草的株高、分蘖数量、叶片SPAD值和生物质产量均具有显著的促进作用(P<0.05);生物质产量与土壤氮素浓度之间的回归分析表明,在挖沙废弃地上获得柳枝稷、荻和芦竹最高生物质产量的适宜土壤氮素浓度分别为115.1 mg.kg-1、131.0 mg.kg-11、25.1 mg.kg-1。

| Abstract: | Bioenergy grass is one of the biomass resources with great development potential.In order to obtain the basic data about the fertilizer effect on bioenergy grasses on marginal lands of North China,a field experiment was conducted to study the effect of nitrogen fertilizer on growth characteristics and biomass yield of switchgrass(Panicum virgatum L.),silverreed(Triarrhena sacchariflor(Maxim.) Nakai),and giantreed(Arundo donax L.) on abandoned sand excavation lands in Beijing suburban areas.The results show ... |
