2017-2020年东北黑土保护性耕作土壤理化性质及耕地产量数据库

为明确不同深松技术下东北黑土耕地的土壤理化性质影响，与2017-2020年进行田间试验采样，数据收集。根据任务书考核指标，本任务需要对东北黑土地区深松技术应用下土壤理化性质变化及坡耕地不同垄作措施下土壤理化性质变化进行监测记录，本数据包含了2017年-2020年数据，包含土壤含水率、容重、CNPK和产量。

To clarify the effects of different subsoiling technologies on the soil physical and chemical properties of black soil farmland in Northeast China, field experiment sampling and data collection were conducted from 2017 to 2020. According to the assessment indicators specified in the task document, this task requires monitoring and recording the changes in soil physical and chemical properties under the application of subsoiling technologies in Northeast China's black soil region, as well as the changes in soil physical and chemical properties under different ridge tillage measures on sloping farmland. This dataset covers data from 2017 to 2020, including soil moisture content, bulk density, CNPK, and crop yield.
