摘要： Promoting more sustainable agriculture while simultaneously meeting the increased demands for food due to the growing population is a great challenge in the 21st century. Here we addressed this challenge by conducting on-farm field experiments at 40 sites across the broad aro-ecological maize region in China during 2017-2018. According to a modern understanding with emergy and economic aspects, a set of new variety-based low emergy system was developed. Compared with the current traditional farmers' system, the new system improved the sustainability (emergy sustainability index) by 19% and increased economic return by 47% while similar productivity (maize yield) was achieved. More than 80% of the modeled yield potential was realized. Moreover, the decrease of nonrenewable materials input in the new system contributed to 88% of the sustainability improvement. As food and resource concerns become more severe in many global regions, this new system is likely to supply a typical case and could be adopted widely to realize the United Nations Sustainable Development Goals (SDGs) in agricultural transformation.
