dBEF monoculture aboveground plant biomass in 2017

The dBEF experiment (Determinants of Long-Term Effects on Biodiversity and Ecosystem Functions) was established in 2016 to disentangle the effects of plant history and soil history on ecosystem properties. To assess species performance in monocultures, we also established dBEF monocultures without any legacy effects of soil or plant history. These are referred to as treatment D1 in the dBEF experiment. In contrast, monocultures with legacy effects—so-called "old monocultures"—correspond to treatment D3.

This dataset is productivity of the dBEF monocultures in 2017. Two biomass samples are taken per year (in May and August).

生物多样性与生态系统功能长期效应决定因子实验（Determinants of Long-Term Effects on Biodiversity and Ecosystem Functions，简称dBEF实验）于2016年启动，旨在厘清植物历史与土壤历史对生态系统属性的影响效应。为评估单作群落中的物种性能，我们同步建立了无任何土壤或植物历史遗留效应的dBEF单作群落，该处理在dBEF实验中被标记为D1组。与之相对，带有历史遗留效应的单作群落——即所谓的‘老旧单作群落’——对应D3处理组。
本数据集收录了2017年dBEF单作群落的生产力数据。每年采集两次生物量样本，采样时间分别为5月与8月。
