沼气系统在稻田养鱼中的应用

The Application of the Biogas Systems in the Rice Field Pisciculture

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。

Rice field piseiculture is a comprehensive ecological agricultural mode, which can better combine rice farming with fish cultivation and optimize planting and breeding at the same time. It eventually allows farmers to realize rice-fish good harvest. The efficient ecological model has great value to promote the agricultural economy development. The core of this paper is that rice field piscicuhure is connected to other planting and livestock and poultry breeding on the basis of traditional rice-fish, which is the center of ＂biogas system＂ and forms the eco- logical agriculture pattern of ＂promoting biogas system by animal husbandry, promoting animal husbandry by agriculture, promoting rice field piseieuhure by biogas system ＂. This article mainly is discussed from the significance and ecological cycle of the traditional rice field piscieul- ture, the ecological cycle and benefits of the rice field piseieulture connected to biogas systems and the development strategies of rice field pis- eiculture in the future. It highlights that biogas system plays an important role in the development of rice field piscieuhure to compare their benefits. It enlarges the scope of rice-fish ecology and enhances the activity and stability of the agricultural ecosystem, finally realizing the sustainable development of rural economy.
