摘要: 北方稻鱼共生试验结果表明,稻鱼田稻谷产量略增;能量产投比和光能利用率分别比对照高0.08%和0.1%;土壤有机质高0.24%;纹枯病发病率低3.8%;纯收入每公顷增加900元,表现出良好的共生效应.

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.
