采用田问试验及环境经济学方法研究免耕稻-鸭生态种养技术的生态、经济效益。试验结果表明：农户采用免耕稻一鸭生态种养技术对稻田杂草的控制效果显著；在晚稻分蘖盛期和孕穗期，采用免耕稻鸭生态种养技术对稻二化螟防效达100％，稻纵卷叶螟发生率分别比免耕抛秧不养鸭的稻田低48．05％、93．55％，免耕抛秧养鸭稻田中水稻纹枯病的病株率比免耕抛秧不养鸭的稻田分别低48．15％、38．21％；在稻田甲烷排放高峰期（晚稻分蘖始期-分蘖盛期），免耕抛秧养鸭对甲烷排放的控制效果明显，分别比翻耕抛秧不养鸭稻田、免耕抛秧不养鸭稻田的甲烷排放量减少4．723g／m^、2．333g／m^2，晚稻整个生育期间，...

This study is aimed at the ecological and economical benefits of the rice-duck ecological management technique with no-tillage through the adoption of field experiment and environmental economic approaches. The results showed that the farmers' control over field weeds was remarkably effective with the application of this technique. In the initial tillering stage and the full tillering stage of late rice, the rice-duck ecological management technique with no-tillage was 100% effective in the prevention of Chilo suppressalis. The incidence rate of Cnephalocrocis medinalis was 48.05% and 93.55% l...
