Method for combining soilless culture of strawberry with high-density aquiculture of snakehead

Abstract

The invention provides a method for combining soilless culture of strawberries with high-density aquiculture of snakeheads and relates to the technical field of agriculture. An organic ecological soilless culture system is established outside a snakehead aquiculture pond, is used for planting strawberries or other fruits and vegetables and is connected with the snakehead aquiculture pond through an underground water circulating pipeline, water in the snakehead aquiculture pond is continuously purified under the purifying effect of soilless culture media, nutrients are provided for the fruits and the vegetables by using the large quantity of snakehead excrement, the culture media are used for purifying aquiculture water, a pond still water aquiculture mode is changed to be a running water aquiculture mode and the cyclic utilization of water resources is realized. Since the water in the pond is continuously purified under the purifying effect of the soilless culture media, the nutrients are provided for the fruits and the vegetables by using the large quantity of snakehead excrement, the culture media are used for purifying aquiculture water, the pond still water aquiculture mode is changed to be the running water aquiculture mode, the pond aquiculture goals of cyclically utilizing the water resources, saving the energy, protecting the environment and achieving sustainable development are realized.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for combining soilless cultivation of strawberries with high-density cultivation of blackfish. Background technique [0002] In recent years, the black fish market has become very popular, and the breeding of black fish in ponds has gradually risen. Breeding black carp has brought considerable economic benefits to fish farmers. However, the traditional farming methods use tidyed ditch rivers or artificially excavated ponds and still water bodies for aquaculture production. The farming technology and technology are relatively backward, and water resources cannot be effectively utilized. The quality and safety of aquatic products cannot be guaranteed. The reason is that the black fish has a large food habit and a lot of excrement, which can quickly make the pond water fertile, and the fertile water causes plankton to multiply, which can easily cause oxygen deficiency ...

AI Technical Summary

Problems solved by technology

When hypoxia occurs, the pond water is usually changed, or when the hypoxia is severe, chemical agents are sprayed on the surface of the pond to kill plankton to increase the dissolved oxygen in the pond, which wastes energy and pollutes water quality
