Research status and prospect of aquaponics technology and its system equipment
China's freshwater aquaculture production ranks first in the world,but problems such as water eutrophication,low production efficiency and unguaranteed aquatic product quality caused by excessive feeding and backward aquaculture mode seriously restrict the healthy development of aquaculture industry.Therefore,the development of aquaponics and other ecological breeding models is an important way to accelerate the development of ecological circular agriculture,finally realizing the green and sustainable development of agriculture.Aquaponics technology can achieve high utilization of nitrogen and water resources,and produce agricultural products with remarkable ecological benefits.Aquaponics system includes aquaculture,aquaculture tail water pretreatment,microbial degradation and transformation,crop cultivation and other links,involving a variety of agricultural production processes and equipment,which requires high technical and professional level of personnel engaged in the related research and production.This paper summarized the development status of modern aquaponics technology at home and abroad,introduced the equipment composition and mode characteristics of aquaponics system,and analyzed the characteristics of aquaponics technology and equipment in the actual production process of our country and the reasons preventing their wide application.Prospects and suggestions were made for the future development of aquaponics technology,which could provide a reference for the research of aquaponics technology.
