能源作物芦苇适宜收获期研究
Research on the Optimal Harvesting Time of the Energy Crop of Phragmites australis
摘要
Abstract
In this study,Phragmites australis in Dongting lake area were harvested at different growth stages to analyze the main growth indices of Phragmites australis and the chemical composition of cellulose,hemicellulose and lignin in order to acquire the optimal harvesting time for ethanol production.Results showed that the dry weight of stalks was increased significantly throughout the crops'growth,especially from July to the middle of September,which increased about 2.10 g a day of per plant;the content of cellulose was about 41％ which reflected an increasing trend of single plant,showing its higher growth rate in the period from July to the middle of September and slower growth rate since late in September;the content of hemicellulose had no obvious change during the whole harvest time,which was around 37％;the content of lignin was from 20.70％ to 25.87％,which increased significantly from May to August and kept stable after September.The yield of dry weight,the content of cellulose and hemicellulose were higher in the middle of September,while the content of lignin was lower.Therefore,the optimum harvesting time of Phragmites australis for ethanol production was around the middle of September with the consideration of the yield of dry weight,cellulose,hemicellulose and lignin.关键词
