Abstract
In this paper,in vestigations were made on the biomass (aboveground parts)of Bambusa rigida and physical and chemical properties of soil in Zhuhai town and Longtou town of Changning county The results showed that (1) the differences were not significant between 2 layers of soil(0~20 cm deep, 20~40 cm deep) in soil bulk density, total porosity and saturated water holding capacity (P<0.05). In the 0~20 cm soil layer, the total N, total K and available N showed a significant difference (P>0.05), but the rest data indicated no significant difference (P<0.05). (2) The number of 2-year-old bamboos was obviously larger than that of 1-year-old bamboos per hectare in Zhuhai town, the former was 1.77 times that of the latter, while the difference was not significant in Longtou town. (3) The average DBH of 1-year-old bamboos in Zhuhai town was smaller than that in Longtou town, while that of 2-year-old bamboos was higher than that in Longtou town. (4) The average biomass of 1-year-old bamboos in Zhuhai town and Longtou town was 11.22±2.34 T/per hectare and 6.64±0.87 T/per hectare respectively. The average biomass of 2-year-old bamboos was 39.23±8.66 T/per hectare and 8.10±2.12 T/per hectare respectively, all of which were significantly different (P<0.05). (5) In order to increase the output, it was necessary to adopt reasonable management measures, such as applying P fertilizer and K fertilizer.
