The utility model discloses a fish and vegetable symbiotic composite cultivation
system suitable for a light and simple facility, which comprises an
aquaculture pond, a soil cultivation
system, a
tail water pond and a water cultivation
system, and the right side of the soil cultivation system is fixedly connected with the surface of the
tail water pond through a communication
assembly. The front side of the water culture system is fixedly connected with the surface of the
aquaculture pond through a circulation
assembly. According to the fish and vegetable symbiotic composite cultivation system suitable for the light and simple facility, a small amount of
tail water is discharged from sediments at the bottom of the
aquaculture pond by starting the second water pump and enters the tail water pond, and after microbial
fermentation and mineralization, day lily cultivated in soil is irrigated through the water and
fertilizer integrated system, so that the problems of waste
discharge and
nitrate excess in the aquaculture pond are solved;
nutrition ingredients needed by growth of the day lily are provided, ecological utilization of aquaculture
water resources and waste is achieved, water-saving and weight-losing cultivation of the day lily is achieved, the production cost is reduced, and benefits are improved.
