Aboveground plant biomass from the Jena Experiment (Monocultures, year 2005)@en

This data set contains aboveground plant biomass in 2005 (Sown plant community, Weed plant community, Dead plant material, and Unidentified plant material; all measured in biomass as dry weight) of the monoculture plots of a large grassland biodiversity experiment (the Jena Experiment). In the monoculture plots the biomass of the sown plant community contains only a single species per plot and this species is a different one for each plot. Which species has been sown in which plot is stated in the plot information table for monocultures (see further details below). The monoculture plots of 3.5 x 3.5 m were established for all of the 60 plant species of the Jena Experiment species pool with two replicates per species. These 60 species comprising the species pool of the Jena Experiment belong to four functional groups (grasses, legumes, tall and small herbs). Plots were sown in May 2002 and are since maintained by bi-annual weeding and mowing. […]本数据集收录了大型草原生物多样性实验——耶拿实验（Jena Experiment）单播样地2005年的地上植物生物量数据，涵盖播种植物群落、杂草植物群落、枯落植物材料与未鉴定植物材料四类组分，所有组分均以干重生物量为计量单位。单播样地内每个样地仅种植单一物种，且不同样地的播种物种各不相同。各单播样地所播种的具体物种信息，详见单播样地信息表（详见下文进一步说明）。针对耶拿实验物种库中的全部60种植物，均设置了规格为3.5米×3.5米的单播样地，且每个物种对应2个重复样地。构成该物种库的60个物种隶属于四大功能群：禾草类、豆科类、高大草本与小型草本。所有样地于2002年5月完成播种，此后通过每年两次的除草与刈割进行管护。[…]
