摘要：

稻鳖异位共生是一种新的稻鳖综合种养模式,具有“面积占比小、养殖管理易、成活回收率高、综合效益好”等优势,因最早在浙江省桐庐县规模化推广且成效显著而被称为“桐庐模式”。本文系统阐述了该技术的核心要点,包括环境条件优化、田间工程构建、水稻种植精细化管理、中华鳖标准化养殖及尾水循环处理等关键技术。研究表明,科学的环境选择与田间工程设计是技术实施的基础,水稻与鳖的协同管理(如中华鳖粪便肥田)可以显著减少化肥使用量,降低农业面源污染,提升土壤肥力与生物多样性,形成“种养互惠”的生态循环体系。实证分析表明,该模式可提高土地利用率15%~20%,稻米和鳖产品附加值提升50%以上,每667 m2综合收益超万元。目前,桐庐县已推广示范面积达848.33 hm2,实现经济、生态与社会的协同增效,为农业绿色转型提供了可复制的实践范式。研究结果可为稻鳖异位共生技术的标准化推广和农业可持续发展提供重要参考。

Abstract:

The ex-situ symbiosis of rice and turtle is a new integrated rice-turtle farming model, which has advantages such as “small area proportion, easy farming and management, high survival and recovery rate, and good comprehensive benefits”. It is called the “Tonglu Model” because it was first promoted on a large scale in Tonglu County, Zhejiang Province, and achieved remarkable results. This paper systematically expounds the core points of this technology, including key technologies such as the optimization of environmental conditions, the construction of field engineering, the refined management of rice planting, the standardized breeding of Chinese soft-shelled turtles and the recycling treatment of tail water. Results showed that scienjpgic environmental selection and field engineering design are the foundation of technology implementation. The collaborative management of rice and turtles (such as fertilizing fields with Chinese soft-shelled turtle manure) can significantly reduce the use of chemical fertilizers, lower agricultural non-point source pollution, enhance soil fertility and biodiversity, and form an ecological cycle system of “mutual benefit between planting and breeding”. Empirical analysis showed that this model can increase land utilization rate by 15% to 20%, raise the added value of rice and turtle products by more than 50%, and achieve a comprehensive income of over 10 000 yuan per 667 m2. At present, Tonglu County has promoted and demonstrated an area of 848.33 hm2, achieving synergy among the economy, ecology and society, and providing a replicable practical model for the green transformation of agriculture. The results can provide important references for the standardized promotion of the rice-turtle ex-situ symbiosis technology and the sustainable development of agriculture.
