| Abstract: | Objective] To study the polyculture mode of turtle,fish and shrimp in paddy field,overcome the problem of ecological environment deterioration,frequent diseases and declined flavor caused by high-density monoculture.Method] Three patches of paddy fields,which had good water sources,irrigation and drainage facilities,were selected as the experimental field to carry out the polyculture experiment of turtle,fish and shrimp,the economic and ecological benefits were analyzed.Result] After ten months of culture,a total of 6 904.3 kg of turtles,1 428 kg of shrimps,3 744 kg of fish and 24 635 kg of rice were harvested,the feed conversion rates of turtles and shrimps were 1.8 and 1.6.The total output value was 813 000 RMB,net profit was 432 000 RMB,the average profit was 127 065 RMB /hm2,and the input-output ratio was 1∶2.13.Conclusion] The polyculture model has remarkable economic and ecological value,and is worthy to be popularized in the whole province. |
