摘　　要：【目的】为探索稻田春季翻耕灌深水沤田对早稻一代二化螟的防控技术及其效果。【方法】于2019年在江西吉安峡江县进行了田间试验,测试稻田翻耕不同时期和灌深水沤田不同持续时间对二化螟的防控效果。【结果】春季稻田耕沤可压低越冬代二化螟成虫基数,控制一代二化螟为害。在二化螟化蛹高峰期耕沤稻田,防控效果优于化蛹始盛期耕沤,且耕沤时间越长,防控效果越好。【结论】研究结果可以指导水稻种植户结合稻田翻耕整地防控二化螟和为水稻绿色防控技术集成提供一种便捷农业防控措施的支持。[Objective]To explore paddy spring ploughing deep water retting irrigation of the early generation 2 moth prevention and control technology and its effect.[Methods]in jiangxi province in 2019,Xiajiang county the field experiment was carried,the test period of paddy fields tillage and deep water retting irrigation duration of two moth control effect.[Results]the results showed that the spring paddy fields tillage retting could depress overwintering generation 2 moth adult base,control generation 2 moth.In two moth pupa peak tillage retting paddy fields,and the prevention and control effect was better than that of pupation plow retting from the beginning stage,and the longer plow retting,prevention and control effect was better.[Conclusion]The results can guide the rice farmers in combination with two moth and for prevention and control of paddy fields tilling the soil preparation of rice green integrated prevention and control technology to provide a convenient agricultural prevention and control measures of the experimental support.
