Effects of greenhouse utilization duration on the evolution of soil quality in highland mountain vegetable farmland

The data for this study is based on detailed interviews with farmers and thorough field investigations. Soil sampling was conducted in greenhouse vegetable planting areas in Xiao Jie Town and Yanglin Town in Songming County, Kunming City, Yunnan Province, China. The selected fields had consistent soil types, crop varieties, irrigation practices, and production techniques, but varied in the durations of greenhouse utilization. The data includes open-field farmlands that have not undergone greenhouse utilization (OF), as well as farmlands with greenhouse utilization durations of 2 years (G2), 5 years (G5), and 10 years (G10).

本研究所用数据基于对农户的详实访谈与全面的田间调研。本次土壤采样工作开展于中国云南省昆明市嵩明县小街镇与杨林镇的设施蔬菜种植区域。所选样地的土壤类型、作物品种、灌溉方式与生产技术均保持一致，仅设施大棚使用时长存在差异。本数据集涵盖未使用设施大棚的露地农田（OF），以及设施大棚使用时长分别为2年（G2）、5年（G5）与10年（G10）的农田。
