冬闲稻田稻虾绿色种养安徽模式与技术探讨

Discussion on Green Rice-crayfish Farmingmodel and Technique of Winter-fallowed Paddy Fields in Anhui Province

为保护环境、充分利用资源、实现可持续农业发展,利用冬闲稻田进行稻虾绿色种养,构建稻渔种养复合生态系统,可改变农村生活环境,提高粮食质量安全。全椒县创制了冬闲稻田稻虾绿色种养安徽模式,稻虾连作共作稻田比对照田,水稻增产1222kg/hm2,增加利润2744元/hm2。在水稻稳产增产的背景下,实现化肥减量457kg/hm2,农药减少使用10.74kg/hm2,水稻和小龙虾合计投入产出比1︰2.66。该模式应用前景广阔,可引导安徽沿江大力发展稻田生态养殖,促进农业增效、农民增收、农村经济发展。

To protect environment,use resources effectively and realize sustainable agricultural development,winterfallowed paddy fields were used to culture crayfish to establish compound ecosystem,which could improve the rural living environment and quality security in grain.Themodel was created in Quanjiao country of Anhui province.As compared to that of control fields,in per hectare,the increasing rice yield was significant which was 1222kg and rice profit increased 2744 yuan.Under the background of stable and increase output of rice,for per hectare,the consumption of chemical fertilizer and pesticides decreased 457kg and 10.74kg,respectively,and the output-to-input ratio was 1:2.26.The core key technologies showed wide application prospect,and could apply in Anhui area along Yangtze River to develop ecological culture in rice fields,promote agricultural efficiency,increase farmers'income and develop rural economy.
