| 为探讨割手密作为能源植物的产能潜力，从纤维素、半纤维素、木质素、粗灰分和热值等方面对“外收
集的割手密资源进行产能潜力评价。结果表明，30 份割手密的纤维素和半纤维素总含量为41.75%~69.13%，木质素
含量为2.16%~11.75%，粗灰分含量为4.79%~9.34%，热值为16.00~17.69 MJ/kg与其他植物相比，割手密的纤维素和
半纤维素含量较高，热值较大，木质素和粗灰分含量较低曰从木质纤维素制燃料乙醇的角度出发，割手密作为能源植
物进行开发具有很大的潜力。通过聚类将30 份割手密种质分为高产能型，中等产能型、低产能型等3 种类型。 |
| 英文摘要: |
| In order to research the energy productivity potential of Saccharum spontaneum L. as an energy plant, the
cellulose, hemicellulose, lignin, ash content and caloric value of wild S. spontaneum L. resources were determined in this
study. The results showed that the cellulose and hemicellulose contents of 30 S. spontaneum L. resources were in the range
of 41.75% to 69.13%, the lignin contents were in the range of 2.16% to 11.75%, the ash content was in the range of 4.79%
to 9.34%, and the caloric value was in the range of 16.00 to 17.69 MJ/kg. Compared with other plants, the cellulose and
hemicellulose contents and caloric value of S. spontaneum L. resources were higher, while the lignin and ash contents were
lower. It indicated that these S. spontaneum L. resources had great potential as energy plants for alcohol production. A
cluster analysis was also carried on the 30 S. spontaneum L. resources, and it finally obtained three clusters which were
high energy productivity type, medium energy productivity type and low energy productivity type, respectively. |
