典型池塘养殖模式的氮磷收支研究进展

The Research Progress on Nitrogen and Phosphorus Budget of Typical Pond Culture Model

池塘养殖是中国水产养殖主要的经营模式,对中国水产养殖业的发展有着重大作用,而在池塘养殖系统中,氮、磷是水体中植物所必须的营养元素,探究其收支是评价池塘养殖系统中氮、磷的利用率、转化率及养殖水体污染程度的有效方法。综述了近年来池塘养殖系统中的氮、磷收支情况及系统中养殖生物对氮、磷的利用率,分析池塘养殖系统中氮磷收支研究的意义,为减少水体中氮磷的沉积、提高养殖生物对氮磷的利用率、进一步优化养殖模式、降低对生态环境的污染提供参考。

Pond culture is the main business model of aquaculture in China,which plays a significant role in the development of aquaculture in China.In the pond culture system,nitrogen and phosphorus are essential nutrients for plants in the water.Exploring their balance is an effective method to evaluate the utilization efficiency,conversion efficiency and aquaculture pollution level in the pond culture system.This paper summarized the nitrogen and phosphorus budget and the utilization rate of nitrogen and phosphorus by aquaculture organisms in the pond culture system.It analyzed the significance of the research on nitrogen and phosphorus budget in the pond culture system,and provided a reference for reducing nitrogen and phosphorus deposition in the water,improving the utilization rate of nitrogen and phosphorus by aquaculture organisms,further optimizing the aquaculture model,and reducing the pollution to the ecological environment.
