摘要
本文在比较林地与农地立地条件差异的基础上,提出了林地施肥种类的特殊性,通过对竹林输出养分研究,论述了竹林土壤加速酸化和退化成因;并根据毛竹生产需求,提出了相关的地力维护策略。
Based on the differences of soil conditions between farmland and forestland, the paper came up with the particularity of fertilizers for forestland. Through the research on the output of nutrients of bamboo forest, this paper discussed the reasons for accelerated acidification and degradation of soil in bamboo forest. Finally, based on the demand for the production of Ph. pubescens, the maintenance strategy for. soil fertility maintenance was put forward.
