摘　　要：采用每30(T1)、60(T2)、90(T3)、120d(T4)刈割1次4个处理,分析刈割频率与产量的关系以及刈割频率对光合生理生态的影响。结果表明:皇竹草的刈割频率对产量有着至关重要的影响。在湛江地区,不同处理的皇竹草的产量高低为T3>T2>T1>T4,不同处理的皇竹草的同化能力强弱为T3>T2>T1>T4,T3处理的皇竹草产量最高,为最佳刈割频率。There were 4 treatments of cutting frequency：every 30 days（T1）, every 60 days（T2）, every 90 days（T3） and every 120 days （T4） in this study, to analyze the relationship between different cutting frequency and yield,and the effect of different cutting frequency on photosynthetic physioecologica.The result indicated that the cutting frequency affected Pennisetum Hydridun’s yiled significantly.In the region of Zhanjiang, the yiled of different treatments was resulted as T3 T2 T1 T4,assimilative capacity of different treatments was resulted as T3T2T1T4.The yield of T3 was the highest ,it was the best suitable cutting frequency.
