摘 要 ：4月中、下旬出现在英国的Hampsfell(英格兰的西北部)地面的蕨菜，以前两个月的生长速度最快，9月叶片达最大高度，但其重量高峰则出现在8月。地上部分生物量也以8月为最高，平均792克·米-2，其后逐渐下降，于11月地面部分枯死。地下部分的生物量季节变化不很明显，但随着地上部分的生长，地下部分的生物量也有所增长。土层深度是影响蕨菜生物量的最重要因子。蕨菜草地生态系统的第一性生产量平均为778克·米-2·年-1,在土深地段平均为918克·米-2·年-l，在浅土地段为525克·米-2·年-l。

Abstract:Bracken young shoots oil Ha mpsfell in England appeared above ground in the middle or end of April and grew rapidly in the first two months. The maximum height of fronds was reached in September and the peak weight of fronds appeared in August.The peak biomass of bracken aerial part on Hampsfell averaged 792g.m-2 in August and then declined. The bracken aerial part died in November. The seasonal variation of bracken below ground biomass was not marked but the below ground biomass more or less increased with the growth of aerial part. The depth of soil was the most important factor influenced on the bracken biomass of Hampsfell. The primary production of bracken ecosystem averaged 778g.m-2yr-1, with maximum yield of 918g.m-2yr-1 on deep soil and minimum yield of 525g.m-2yr-1 on shallow soil.
