2017-2019年辽宁玉米田间优化配置模式光资源高效利用研究数据集

含有中文名、种植密度、处理、重复、平均值、标准误、地上干物质重、产量及产量构成因素（穗长、穗粗、穗行数、行粒数、百粒重）等数据。主要包括2017年地上干物质、2017光能利用效率以及2017年种植模式密度试验考种数据、2019年种植模式密度试验考种数据。This dataset includes data such as Chinese cultivar names, planting density, experimental treatments, replicates, mean values, standard errors, above-ground dry matter weight, grain yield, and yield components (including ear length, ear diameter, number of kernel rows per ear, number of kernels per row, and 100-kernel weight). The core contents of the dataset mainly cover above-ground dry matter data from 2017, light use efficiency data from 2017, seed trait investigation data from planting pattern and density trials conducted in 2017, and seed trait investigation data from planting pattern and density trials conducted in 2019.
