Data of Monocrop Vs Polycrop Yield Experiments (2019-2021)

Data obtained from field experiments with 7 crop species, planted in alternate rows (ROW), diagonal rows (DIAG), and semi-random (SRAN) planting designs in 2019, and the same species planted in ROW and in random (RAN) planting designs. Unlike all previously published experimental data, these data pertain to the first experiments with 7 crops in replicated polycultutures, in different planting designs. Land Equivalent Ratio (LER) and Relative interaction index (RII) were calculated for each cropping pattern.本数据集来源于2019年开展的田间试验，供试作物共7种，试验设置了交替行种植（alternate rows, ROW）、对角线行种植（diagonal rows, DIAG）与半随机种植（semi-random, SRAN）三种种植布局；同时还包含同批次作物采用交替行种植（ROW）与完全随机种植（random, RAN）布局的试验数据。相较于所有已发表的同类试验数据，本数据集首次针对7种作物的重复混播栽培体系开展了不同种植布局的相关试验。本数据集针对每种种植模式计算了土地当量比（Land Equivalent Ratio, LER）与相对互作指数（Relative interaction index, RII）。
