连续施肥对毛竹林生长特征及生物量空间构型的影响
Growth characteristics and biomass distribution of Phyllostachys pubescens stands with changes in fertilization time
摘要
Abstract
It was important to study the Phyllostachys pubescens stands with different fertilization periods ( Ⅰ : without fertilization, Ⅱ : 5 years of fertilization, and Ⅲ : 13 years of fertilization)growth characteristics and biomass distribution pattern for maintain the long-term productivity. Growth characteristics and biomass distribution of three Phyllostachys pubescens stands with different fertilization periods were studied by field survey in Yong' an County, Fujian Province. Results showed that biomass was in the order of Ⅱ > Ⅲ > Ⅰ . The mass fraction of bamboo stems decreased with fertilization time, whereas the mass fraction for bamboo branches, leaves, roots, and culm stumps increased. Biomass of the shrub layer was in the order Ⅲ >Ⅰ> Ⅱ. The mass fraction for shrub branches and leaves increased in forest Ⅲ , was in the order of Ⅲ > Ⅰ> Ⅱ , and the mass fraction for shrub roots decreased in forest Ⅲ , was in the order of Ⅱ > Ⅰ > Ⅲ. The mass fraction of grass leaves decreased with fertilization time as the mass fraction of grass roots increased. The litter mass increased with fertilization time. Therefore, litter increases could be related to higher productivity with fertilization in bamboo stands; also, since major economic issues with bamboo concerned its culm, the decrease in bamboo culms with fertilization increases over time could reduce economic gains which fertilization sought to increase.关键词
