[ Objective ] The purpose was to study the effects of rice-duck integrated farming on water and soil temperature in paddy field and dry weight of rice at each growth stage, and then discuss its feasibility. [ Method] The randomized block dftRign was used to carry out field comparison test, and the measuring indices were water and soil temperature in paddy field and dry weight of rice at different periods. [ Result ] The results showed that rice-duck integrated farming increased water and soil temperature in paddy fields and increased dry weight of rice, so it improved physical condition of rice field. [ Conclusion] Kice-duck integrated farming improves rice fields water environment, and has positive effects on the rice growth and development.%[目的]研究云南稻(Orza sativa L.)-鸭共生对稻田水地温及各生育时期干物质重的影响,探讨稻鸭共作模式的可行性.[方法]采用田间对比试验,随机区组排列.测定指标为稻田土温、水温及不同时期水稻干物质重.[结果]稻-鸭共生模式能改善稻田的物理状况,增加稻田水体和土壤温度,提高水稻的干物重.[结论]稻-鸭共作对改善水体理化性质,促进水稻的生长发育具有积极的作用.
