2018-2019年辽宁铁岭地区旱田坡地固土减蚀监测数据集

在辽宁省铁岭市典型黑土区坡耕地设置野外径流场，用于观测因降水引起的坡面水土流失数据。设计在试验径流场同一坡面（坡度6°）设置4个处理，分别为横垄、免耕、秸秆覆盖、秸秆粉碎还田等措施。每个处理3次重复，另设对照顺垄小区1个，共设置13个试验小区。种植作物为玉米，均为垄台种植。试验小区下部设有集水槽，用于承接小区径流及泥沙，并引入集流桶。径流量及泥沙量通过人工采集和实验室烘干法测算。A field runoff plot experiment was established on sloping farmland in the typical black soil region of Tieling City, Liaoning Province, to monitor slope soil and water loss data induced by precipitation. Four experimental treatments were arranged on the same slope (6° slope gradient) of the test site, including cross-ridge planting, no-tillage, straw mulching, and crushed straw incorporation into farmland. Each treatment had 3 replicate plots, plus 1 control plot with straight ridge planting, resulting in a total of 13 experimental plots. The crop planted across all plots was maize, with all crops grown on ridge tops. A water collection trough was installed at the lower end of each experimental plot to collect runoff and sediment, which was then guided into a runoff collection bucket. Runoff volume and sediment yield were quantified via manual sampling and laboratory drying method.
