三江县稻渔综合种养绿色高效配套技术研究与示范推广
Research, Demonstration and Extension of Green and Efficient Techniques for Integrated Rice and Fish Farming in Sanjiang

为了发展特色产业，助力贫困山区脱贫和乡村振兴，自2018年以来，桂北高寒山区三江侗族自治县的农业科技工作者以实施“种稻养鱼”特色扶贫产业项目为载体，对当地“种稻养鱼”模式及其配套技术进行了持续多年的探索，通过开展了优质稻品种(组合)筛选、栽植密度、鱼苗投放量、施N水平、留茬高度等小(大)区(田)对比试验，最终形成了适合在当地“种稻养鱼”稻田推广应用的坑沟式“优质稻 + 再生稻 + 鱼”稻渔综合种养模式的绿色高效配套技术体系。2018~2020年在该县15个乡镇累计示范推广应用2833.3 hm²，水稻平均增产314.1 kg/667m²、增幅达68.1%，鲜鱼平均增产19.6 kg/667m²、增幅达83.8%，增收1837.8元/667m²，收入接近翻番，从而将“绿水青山”变成了“金山银山”。
In order to develop distinctive industries and help poverty alleviation in poor mountain areas and rural revitalization, since 2018, agricultural science and technology workers in the Sanjiang areas of northern Guangxi are using the “Rice and fish farming” project as a carrier to help the poor, the local model of “Growing rice and raising fish” and its supporting techniques have been explored for many years, a comparative experiment was carried out in small (large) areas (fields), such as selection of high quality rice varieties (combinations), planting density, amount of fish fry, N application level, stubble height, etc. Finally, a green and high-efficient technology system of pit-ditch rice-regenerated rice-fish integrated rice-fish farming model was formed. From 2018 to 2020, 2833.3 hm² was applied in 15 townships of the county. The average yield of rice increased by 314.1 kg/667m², with an increase of 68.1%. The average yield of fresh fish increased by 19.6 kg/667m², with an increase of 83.8%, with an increase of 1837.8 yuan/667m², income nearly doubled, thus turning “Green Water and Green Mountains” into “Mountains of Gold and Silver”.
