摘　　要：在总结前人研究的基础上,提出了将经济效益更好的野鸭品种"绿头野鸭"代替普通家鸭的一种新型种养技术,即稻-野鸭复合生态种养技术。与单一水稻种植对比,采用该技术能促进分蘖早发和根系生长发育,提高了9.04%的水稻产量,增加了近6倍的单位面积利润,提高了36%的产投比。通过稻-野鸭复合生态种养技术,可在保证水稻生产的前提下显著提高稻田经济效益,调动稻农积极性。The paper summarizes previous researches,presents a new type of complex ecological planting and breeding technology with more economic benefits of mallard displace of duck.Compared with single rice cultivation,it promoted early onset of tillers and rice root growth development,increased rice yield by 9.04%,which was nearly 6 times profit per unit area and more than 36% on variable compression ratio（VCR）.Rice-mallard complex ecological planting and breeding technology made a far-reaching significance on improving the economic efficiency of rice field and mobilizing the enthusiasm of rice farmers in the premise of ensuring rice production.
