三江县稻渔综合种养模式的创新发展及关键技术探讨

Innovation and Development of Integrated Rice-Fish Farming Model in Sanjiang and Its Key Technologies

摘要: 桂北高寒山区三江侗族自治县的农业科技工作者自2004年以来，以实施超级稻 + 再生稻示范推广和特色扶贫产业等项目为载体，多次对传统的“种稻养鱼”模式进行了创新发展，形成了坑沟式“优质稻 + 再生稻 + 鱼”稻渔综合种养模式，并在当地示范推广2833.3 hm2，取得了显著的经济、社会和生态效益，不仅使该县的再生稻生产恢复发展到20世纪90年代中期的规模水平，还为当地农民拓宽了致富渠道，为山区脱贫和乡村振兴做出了重要贡献。笔者根据生产实践，并参考借鉴各地经验，对该县稻渔综合种养模式关键技术进行了探讨。
