Abstract:

Agriculture is the foundation of social-economic development on the Xizang Plateau. Constrained by the region’s natural conditions, agriculture activities are predominantly concentrated in plateau river valley areas, including the Yarlung Zangbo River, Nyangchu River and Lhasa River. The primary crops cultivated in these areas are grain and oil crops, include highland barley (Hordeum vulgare var. coeleste), wheat (Triticum aestivum) and rapeseed (Brassica rapa var. oleifera), which favor cool climate. The Lhasa National Field Scientific Observation and Research Station of Agro-ecosystem, Xizang (Lhasa Station), is located in the Lhasa River Valley agricultural area in the heart of the Qingzang Plateau, serving as a typical representative site of plateau agricultural regions. With a focus on monitoring the long-term dynamic of the plateau farmland ecosystem, Lhasa Station has established one comprehensive observation field, one long-term experimental observation field and two farmer survey points to conduct long-term and fixed-site observations on typical cultivation patterns of the region’s main crops, including highland barley, wheat, and rapeseed. This dataset includes the observation data of the crop harvest traits and yield in Lhasa River valley collected by Lhasa Station from 2016 to 2020, including five parts: farmland multiple cropping index and crop rotation system, fertilizer input of farmland crops, farmland irrigation, crop harvest trait data, and crop yield data. This dataset will provide scientific basis and data support for agricultural capacity assessment, sustainable agricultural production management and smart agricultural system development in this agricultural area.
