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).
