2003年4～10月,在稻鸭共栖田中,对二化螟发生规律的系统研究结果表明,稻田养鸭能显著减轻二化螟的为害。与对照相比,中稻田养鸭区二化螟为害株率减少13.4%～47.1%;晚稻田减少62.2%。稻鸭共栖能减少化学农药的使用量,具有较好的经济、社会和生态效益。
From April to October 2003, the systematic study on the occurrence of Chilo suppressalis in the rice-duck co-habitat field showed that duck-raising on the rice paddy could significantly reduce the damage of Chilo suppressalis. Compared with the control, ducks in midriffing ducks reduced the damage rate by 13.4% -47.1% and late rice by 62.2%. Rice-duck co-habit can reduce the use of chemical pesticides, with good economic, social and ecological benefits.
