[Method] With Triarrhena lutarioriparia as materials, samples were collected from April 2012 to November 2012 to explore monthly biomass changes and degradation and saccharification of Triarrhena lutarioriparia. [Result] Plant height was improving upon time; holocellulose and cellulose contents were increasing with dry weight of shoot system increasing and achieved the peak at 78.1% and 40% in September. It can be concluded that NaOH pre-treatment efficiency is better, when Triarrhena lutarionparia was treated with 2% NaOH at 100 ℃ for 20 min and reducing sugar yield achieved 178,42 mg/g. [Conclusion] Triarrhena lutarioriparia can be materials for ethyl alcohol production and the optimal harvest time is from middle September to middle October.展开更多
