摘　　要：[Objective] The aim was to analyze biomass accumulation, degradation and saccharification characteristics of Triarrhena lutarioriparia. [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.[目的]对洞庭湖南荻(Triarrhena lutarioriparia)的生物量累积规律与降解糖化特性进行初步研究。[方法]以洞庭湖南荻为试材,于2012年4月至2012年11月采集样品,对湖南洞庭湖南荻的月生物量变化及降解产糖效果进行研究。[结果]南荻株高随时间延长呈增长趋势,随着全秆干重的增加,南荻的综纤维含量与纤维含量也随之递增,9月达最高,分别为78.1%和42.3%;对南荻进行酸碱、碱解、酶解技术研究,从降解糖化效果来看,NaOH预处理后酶解效果最好,即采用2%NaOH于100℃下处理20 min后进行酶解,还原糖得率达178.42 mg/g。[结论]南荻是燃料乙醇生产的良好原料,其采收的最佳时间可定为9月中旬至10月中旬期间。
