| Abstract: | Experiment on rice fish symbiosis in north China showed that the ricce production in rice fish field was a bit higher than control,and the output input ratio of energy,utilization efficiency of solar energy and soil organic matter content increased 0.08,0.1 and 0.24%,respectively.The banded sclerotic blight incidence decreased 3.8% and the net economic income increased 900 RMB yuan per hectare.All the resuts showed that rice fish symbiotic system had a good symbiotic effect. |
