【摘要】 稻鱼种养模式是典型的生态循环农业模式，充分发挥水稻和鱼在同一个生态系统中共生互利的生态效应，减少肥药施用，生产出优质稻米和鱼产品。2022年宁德市农业科学研究所在福建省福安市设立了稻鱼种养试验基地，试验结果显示，每667m~2稻鱼种养区的平均总产值为4 479.4元，水稻单作区的平均产值为2 045.5元，扣除各项成本后，稻鱼种养区的经济效益增加了1 494.2元，经济效益显著提升。总结了宁德山区稻鱼种养模式的关键技术。更多还原

【Abstract】 The rice-fish farming system is a typical ecological cycle agriculture model, which gives full play to the ecological effect of co-production and mutual benefit of rice and fish in the same ecosystem, reduces the application of fertilizers and pesticides, and produces high-quality rice and fish products. In 2022, we set up a rice and fish breeding test base in Fu,an, Fujian Province. The results showed that the average gross output value of rice and fish breeding area per 667m~2 was 4 479.4 yuan, and the average output value of the rice monoculture area was 2 045.5 yuan. After deducting various costs, the economic benefit of rice-fish breeding area increased by 1 494.2 yuan per 667m~2, which significantly improved the economic benefit. This paper summarized the key technologies of rice-fish breeding system in Ningde mountain area, and provided reference for the future rice-fish breeding in eastern Fujian.更多还原
