Management technology for high-efficiency grass carp culture

The invention discloses a management technology for high-efficiency grass carp culture. The management technology comprises the following steps: (1) culture pond management; (2) epidemic prevention management; and (3) feeding management, namely, throwing microbial feeds with different proportions according to different growth time periods of grass carps, wherein the amount of the microbial feed thrown every day accounts for 2-3% of the body weights of fishes when fish fries grow for 10-30d; the amount of the microbial feed thrown every day accounts for 3-5% of the body weights of the fishes when the fish fries grow for 31-90d; the amount of the microbial feed thrown every day accounts for 5-7% of the body weights of the fishes when the fish fries grow for 91-360d; and the amount of the microbial feed thrown every day accounts for 6-10% of the body weights of the fishes when the fish fries grow for 361-900d. According to the technical means adopted by the invention, grass carps can be cultured at high efficien
