Assessing the impacts of greenhouse lifespan 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 exhibited similar soil types, crop varieties, irrigation methods, and production techniques, while their greenhouse lifespan varied. The data includes open-field farmlands that have not undergone greenhouse utilization (OF), as well as farmlands with greenhouse lifespans of 2 years (G2), 5 years (G5), and 10 years (G10).
