摘　　要：以水稻常规单作为对照(CK),研究水鸭(SY)、洋鸭(YY)和绿头鸭(LTY)对稻鸭共生系统土壤理化性质、水稻产量及稻田经济效益的影响,以期为稻鸭共生系统鸭品种选择及模式优化提供理论依据。结果表明,与CK相比,3个稻鸭共生处理总体上均降低土壤全氮、全磷、全钾、碱解氮、速效磷含量,增加土壤速效钾含量,有机质含量无显著变化,pH值均升高;YY和LTY处理水稻有效穗数、结实率和产量均显著增加,穗总粒数均显著降低,SY处理水稻有效穗数、结实率和产量虽有所增加但是差异不显著;3个稻鸭共生处理的经济效益均提高,表现为YY>LTY>SY>CK。综上,稻鸭共生有利于促进水稻对土壤养分的吸收,改善土壤酸化,提高水稻产量和经济效益,以YY处理最优,LTY处理次之。The effects of teal(SY),muscovy duck(YY) and mallard(LTY) on soil physical and chemical properties,rice yield and economic benefit of rice-duck symbiosis system were studied using conventional rice monoculture as control(CK),so as to provide a theoretical basis for duck species selection and mode optimization in rice-duck symbiosis system. The results showed that compared with CK,the total nitrogen,total phosphorus,total potassium,alkali-hydrolyzable nitrogen and available phosphorus contents of soil generally decreased,available potassium content and pH value increased,but organic matter content did not have significant differences under the three rice-duck symbiosis treatments. The effective panicles number,seed-setting rate and yields of YY and LTY treatments significantly increased,while the total grains number per panicle significantly decreased. The effective panicles number,seed-setting rate and yield of SY treatment increased,but the difference was not significant. The economic benefits of the three rice-duck symbiotic treatments all improved,and the order was YY>LTY>SY>CK. In conclusion,rice-duck symbiosis promoted the absorption of soil nutrients by rice,improved soil acidification,increased rice yield and economic benefit,and YY treatment was the best,followed by LTY treatment.
