稻田养鱼是把水稻种植和鱼类养殖有机结合的一种综合生态农业模式,它同时优化了种植业和养殖业,最终让农民实现稻鱼双丰收,这种高效的生态模式对于推动农业经济发展具有较大的促进作用。该研究的核心是在传统稻田养鱼的基础之上,以“沼气系统”为纽带,把除水稻之外的种植业和畜禽养殖业连入其中,形成“以农带牧、以牧促沼、以沼促鱼促稻”的立体生态农业模式。分别从传统稻田养鱼的生态循环及意义、沼气系统与稻田养鱼联合后的生态循环及效益和稻田养鱼的未来展望等方面展开论述,并通过沼气系统联合前后效益的对比凸显出了其对于稻田养鱼的发展具有重要地位和作用——它扩大了稻田养鱼的生态范围,增强了农业生态系统的活力和稳定性,最终实现了农村经济的可持续发展。
Paddy field fish farming is a combination of rice cultivation and fish farming an integrated ecological agriculture model, which also optimizes the planting and breeding industry, and ultimately allow farmers to achieve double harvest of rice, this highly efficient ecological model for promoting agricultural economy Development has a greater role in promoting. The core of this study is to establish a “agriculture-animal husbandry, animal husbandry, animal husbandry, animal husbandry, To animal husbandry swamp, marsh fish to promote rice ”three-dimensional ecological agriculture model. This paper discusses the ecological cycle and significance of fish culture in traditional paddy fields, the ecological cycle and benefits after the combination of biogas system and paddy field fish culture, and the future prospects of fish farming in paddy fields. The comparison of the benefits before and after the biogas system cooperation highlights its It plays an important role in the development of fish farming in rice fields. It expands the ecological range of fish farming in rice fields, enhances the vitality and stability of agro-ecosystems, and finally achieves the sustainable development of rural economy.
