藏粮于技 盐碱地变绿肥田

乡村中国【藏粮于技 盐碱地变绿肥田】中国科学院烟台海岸带研究所黄河三角洲盐碱地农田生态系统观察站站长王光美的研究团队利用传感器等智能化高效作业机具进行土壤监测，从而达到淡水资源的高效利用。2018年以来，盐碱地农田土壤有机质提高22%以上，减少化肥使用量30%以上。Senior researcher Wang Guangmei of Yantai Institute of Coastal Zone Research at the Chinese Academy of Sciences spoke with CGTN reporters on how scientists turned barren saline-alkaline soil into fertile arable land by developing advanced agricultural technology.
