Carbon and Phosphorus Cycles System Using Giant Reed
1.INTRODUCTION Giant reed (Arundo donax) is a perennial, very tall and gramineous plant with the rhizome as shown in Figure 1. The annual productivity of this plant consisting of rhizomes, roots, canes and leaves is about 10 kg (dry weight) /m2/year and the annual phosphorus uptake is considered to be about 10-30 g/m2/year. In addition, the translocation of nutrients such as phosphorus and nitrogen in this plant is an interesting phenomenon. For example, phosphorus accumulated in the leaf is transferred to the rhizome before the leaf is lost in a winter season. These facts mean that giant reed is very promising plant for recovering phosphorus from water environments and also for being utilized as a regional solid bio-fuel. Further more, there is a possibility that valuable biochemicals would be obtained from this plant.
