Abstract

A method for polyculture of ryegrass and Channa chinna according to the present invention is characterized in that it includes the following steps: (1) finishing the pond; (2) sowing ryegrass; (3) throwing fish fry; (4) daily management; (5) fishing. According to the method, the planting of ryegrass and the breeding of sandfish in the pond improve the utilization rate of land resources; and the ryegrass can effectively improve the content of nutrients such as organic matter, nitrogen, and phosphorus in the water quality, and absorb heavy metal elements in the water quality. It is conducive to improving the breeding environment of the sandfish, and improving the yield and quality of the sandfish.

Description

technical field [0001] The invention relates to the technical field of agricultural aquaculture, in particular to a method for polyculture of ryegrass and sand pond snakehead. Background technique [0002] The pond is the place where aquaculture animals live, and the quality of the environmental conditions directly affects the survival and growth of aquatic animals. Scientific regulation of aquaculture water quality is the key to increasing the growth rate of aquaculture species, reducing diseases, and achieving high yield and high quality. After the pond is used for a period of time, some organic particles such as residual bait and aquatic animal feces sink to the bottom of the water, and after the remains of dead organisms are fermented and decomposed, they are mixed with the sediment and other substances at the bottom of the pond to form sediment. A certain thickness of sediment can play a role in supplying fertilizer, maintaining fertilizer and regulating and buffering ...
