稻蛙绿色种养模式研究及其可持续发展策略

稻蛙绿色种养模式是近年来兴起的一种新型稻田综合种养模式,在南方稻区及长江流域具有良好的发展态势,并形成一定的规模。本文采用产业调查,结合试验示范,介绍了稻蛙绿色种养模式的技术特点,如稻田改造、水稻种植、蛙苗繁育与投放和蛙类饲喂与管理等;分析了稻蛙绿色种养模式发展的经济、生态和社会效益;总结了稻蛙绿色种养模式发展中存在的市场机制尚不完善、规模化程度低、产品附加值低、重蛙轻稻、蛙药和饲料使用过量等问题;提出了因地制宜,避免盲目发展,科学投饲和水肥调控以及模式升级,延长产业链等稻蛙绿色种养模式的发展策略,为稻蛙绿色种养模式的可持续发展提供了依据。

Rice-frog Planting and Raising Mode and Its Sustainable Development Strategy

Rice-frog planting and raising is a new mode of paddy comprehensive planting and breeding, it has been rapidly developed in rice planting area in south China and the Yangtze River basin, and has formed a certain scale in recent years. In this paper, we introduced the technical characteristics of the mode, analyzed the economic, ecological and social benefits, summarized the development problems and put forward some development strategies of rice-frog planting and raising mode by investigation and demonstration experiment. The technical characteristics of rice-frog planting and raising are mainly paddy transformation, rice planting, frog seedling breeding and releasing and frog feeding and management, etc. The development problems of the mode are mainly imperfect market mechanism, low degree of scale development, low added value of products, preferring frog to rice, and the overuse of frog medicine and feed. Finally, we propose suggestions for improving the rice-frog planting and raising mode, such as adjusting managements to local conditions, optimizing feeding and regulating water and fertilizer utilization, upgrading the mode and extending the industrial chain, which can provide a basis for the sustainable development of rice-frog planting and raising mode.
