Aboveground plant biomass from the Jena Experiment (Monocultures, year 2004)@en

This data set contains aboveground plant biomass in 2004 (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. […]本数据集涵盖大型草原生物多样性实验——耶拿实验（Jena Experiment）单作样地2004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、枯落植物材料与未识别植物材料，所有生物量指标均以干重计量。单作样地内，每个样地的播种植物群落仅包含单一物种，且各样地的播种物种互不相同。各单作样地对应的播种物种信息，详见单作样地信息表（详见下文详细说明）。耶拿实验物种库共包含60种植物，针对每一种植物设置2个重复样地，单作样地尺寸均为3.5×3.5米。构成该实验物种库的60个物种隶属于4个功能群：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，此后通过每半年一次的除草与刈割进行维护。[…]
