摘要
通过对叶林模式的田间生物量进行调查,同时又对叶林模式更新复壮与不复壮两种处理模式的田间生物量进行了对比分析,发现两种处理模式的年变化规律有着明显的差异。
This experiment investigated the field biomass of the leaf-oriented tree model of Eucommia ulmoides Oliv.. At the same time, we compared the renewal model with the no renewal model. The result showed that,at early May,the field biomass of the renewal model was lower than the no renewal model. But at late December, the result was the opposite.
