Nutrient distribution pattern in Phyllostachys edulis forest with different operating management modes in Northwest Fujian
摘要
Abstract
We used Phyllestachys edulis forest under different types of management and protection in Tianbaoyan Nature Reserve of Yong'an city, Fujian province, as research objective, to investigate the nutrient distribution pattern in P. edulis forest Ⅰ (digging bamboo shoots + weeding), Ⅱ (digging bamboo shoots + weeding + fertilizer) and Ⅲ (digging shoots + weeding + fertilizer + irrigation).The results showed that the proportion of accumulated nutrient amount in vegetable layer increased, while nutrient accumulated proportion in soil layer decreased in forest Ⅱ and Ⅲ. The key to the scientific management was how to balance the nutrients storage in tree layer and soil layer. The amount of accumulated nutrients in forest Ⅲ increased significantly. However, the increment was attributed to the increase in potassium, while the nitrogen and phosphorus storages were decreased. It was an essential element for nitrogen and phosphorus to the plant growth and development. The long-term productivity of bamboo forest may be damaged with the reduction of nitrogen and phosphorus. The accumulation of nutrient elements in different forest layers was in the order of soil layer>tree layer>litter layer>shrub layer> herb layer. The proportion of soil layer nutrient accumulation accounted for more than 99% of total nutrient accumulation. The accumulation of nutrient elements in tree layer was highest among those vegetable layers, and accounted for above 85% nutrient element accumulation.关键词
