摘  要：
针对纤维素类能源草的开发现状,对比分析了南方几种主要种植的象草(Pennisetum purpureum Schumab cv.)、斑茅(Saccharum arundinaceum Retz)、以及几个品种的柳枝稷(Panicum virgatum L.)的能源理化性状,包括干物质含量、热值、纤维素含量、半纤维素含量、木质素含量以及总糖含量,探讨其作为能源用草种质资源制备液体乙醇燃料的可行性。结果得出:株高在400~450 cm时,象草纤维素含量为30.21%~42.34%,半纤维素含量集中在10%~20%之间,木质素含量较高,大多数为20%左右,其中桂闽引象草由于较高的总糖含量26.28%,作为能源草性状较其他品种优。三大类能源草热值在16.60~17.93MJ/kg之间。斑茅的各项含量指标居中,柳枝稷干物质含量、综纤维素含量高,但是干物质产量上象草的较高,是柳枝稷的2倍以上。三者均可作为纤维素类能源草使用。

摘  要：
Based on the current development situation of cellulose energy grass,compared bio-physical-chemical indicators of several kinds of elephant grass planted mainly in the South,arundinaceum and several kinds of switchgrass,such as dry matter content,caloric value,cellulose content,hemicelluloses content,lignin content and total sugar content,we discussed feasibility of them used as energy grass germplasm resources to prepare liquid ethanol fuel. The results showed that: Ta the plant height of 400 ~ 450 cm,elephant grass' s cellulose content was 30. 21% ~ 42. 34%,hemicelluloses content was mainly between 10% ~ 20%,lignin content was high relatively,most kinds were about 20%,among them,thanks to the high content of total sugar,26. 28%,Pennisetum purpureum. cv. Guiminying 's energy performance was better compared to other kinds of elephant grass. Caloric value of three major categories of energy grass was between 16. 6 MJ/kg ~17. 93 MJ/kg. Each energy indicator of arundinaceum ranked at medium,switchgrass was high in dry matter content and holo-cellulose content,but in terms of dry matter yield,elephant grass perform better,was more than 2 times of switchgrass. Three major categories grass could all e used as cellulose energy grass.
