| Abstract: | The number of phyllostachys pubescens shoots and the growth after Ice-snow disaster was investigated. The leaves of phyllostachys pubescens and soil samples were collected. Meanwhile the contents of N, P, K of the samples were analyzed. The results showed that the number of phyllostachys pubescens shoots had increased due to snow disaster, but the snow disaster had some impact on the height and stem growth. The snow disaster had little impact on soil nutrients of phyllostachys pubescens forest, but it had impact on soil organic matter and hydrolyzable nitrogen content. |
