The experimental results show that peat composed of rotton mosses and its preparation can promote the assimilation, utilization and rational distribution of nutrient (N, P and K).

实验结果表明，草炭与制剂可以促进养分的吸收利用与合理分配。

P fertilization increased N, P and K accumulation in tree biomass and nutrient use efficiency in wood and biomass production.

施P肥还增加了树木N、P和K的养分积累量，提高了上述养分的利用效率。

Higher efficiency of nutrient acquisition of root in heterogeneous nutrient environment mainly attributed to large absorption of n, p, K in rich nutrient patch.

异质养分环境中的根系具有较高的养分吸收效率主要缘由在富养斑块中对N、P、K大量的吸收。
