Culm Form Characteristics of Bambusa rigida and the Influence of Special Bamboo Fertilizer
Study on the culm form characteristics of Bambusa rigida, which widely distributed in south of Jiangxi Province , and analysis of the effect of the special bamboo fertilizer on it were conducted through comparison be -tween treatment with special fertilizer and control check (CK).The results showed that internode length varied with a tendency of “short-long-short” model.Fertilization improved the length of the longest internode and the number of nodes . Fertilization had no influence on wall thickness , but could reduce taperingness , and culm weight showed a uniform variation with height dynamics under fertilization .Therefore, the culm form performed better and was easy for utilization under fertilization .The results of equation fitting showed that culm weight had significant correlation with DBH and wall thickness , culm weight had extremely significant correlation with culm height, culm height had extremely significant with DBH and wall thickness .
