A Method to Inhibit the Expansion of Phyllostachys pubescens Stands Based on the Analysis of Underground Rhizome

Cai Liang, Zhang Ruilin, Li Chunfu, Ding Yu(Fudan University, Shanghai 200433, P. R. China)  
Moso bamboo (Phyllostachys pubescens) reproduces by underground rhizome. Its strong ability of expansion has influences on other plants nearby, thus threatening biodiversity. The expansion tendencies of rhizomes for pure Moso bamboo stands and moso bamboo and broad-leaved mixed forests and their growth condition were observed in the West Tianmu Mountain of Lin’an County, Zhejiang Province. It is found that the rhizomes of moso bamboo only expand within the surface layer of 20cm in depth, and rhizomes would bend downward to attempt to surmount obstacles when they come across obstruction (such as rock, section, water flow or strong stem), rather than come out side branches or bend sidewise. Within our investigation regions, the rhizomes of moso bamboo have only two kinds of expansion tendencies, namely, forward or downward, which make the rhizomes no way get to the soil surface through growing upward after they go downward. If rhizome gets into soil too deep or come out of soil and the exposure time to air is too long it will die. The soil with high water content is disadvantage to the growth of rhizomes. Based on these observations, we put forward a new method of“dig pour”to inhibit the expansion of moso bamboo stands.
