    Based on the analysis of fifteen soil profiles and investigation on fi-fty-nine plots of planted fishscale bamboo of different ages through sele-ctiye cutting in the Long He area of Shucheng county, Anhui province,the relationship between the structure of underground rhizome, the depthof its extension, the proportion of vigorous rhizome and the principalphysical properties and the chemical composition of the soil are studied,and 22 regressive equations are also derived. The result shows that the depth of rhizomatous extension is little re-lated to the thickness of soil but is certainly related to the type of sloiand closely related to zhizome ages. The amounts of rhizome distributionwithin 20cm depth and 30cm depth are, respectively, 62.82% and 82.63%.In loam sandy soil with 60-72% sand particles, 16-20% powder particlesand 11-18% clay particles the weight of the rhizomes is larger and theproportion of vigorous rhizomes is higher, but the depth of extension inthe soil is shallower. In the soil with 1.00-1.20 specific gravity, 43-61% total porosity, 33-46% capillary porosity, 0.46-1.24% content oforganic matter in the surface layer of the soil, 0.0080% effective nitrogen,35ppm effective phosphorus and 45ppm effective potassium, the biomassesof underground rhizomes are higher. In loose, fertile and porous soil theextension of rhizome system is deeper.
