稻鸭共生种养不仅能生产无公害的有机农产品,而且对水稻增产具有一定效果。在稻鸭共生基础上,加入鱼、萍、泥鳅、鸡等生物形成稻鸭复合种养模式,比较稻鸭复合种养模式下水稻产量及成熟期地上部分生物量的差异。试验共设6个处理:稻-鱼-鸭、稻-鱼-鸭-萍、稻-鳅-鸭、稻-鳅-鸭-萍、稻-鸡-鸭、稻-鸡-鸭-萍,以常规稻作对照。结果表明,与对照比较,稻鸭复合种养模式下水稻平均增产9.8%,尤以稻-鸡-鸭-萍处理产量最高,增幅达到18.11%;稻-鱼-鸭处理增幅最小,为4.96%;有效穗、结实率以及总粒数等均呈现不同程度的增长;地上部分生物量总和也普遍高于常规稻作,以稻-鸭-鳅处理最高,稻-鸡-鸭处理最低,说明稻鸭复...

The rice-duck symbiotic breeding model can not only produce pollution-free organic agricultural products,but also has a certain effect on rice yield increase. On the basis of rice duck symbiosis,this study added fish,duckweed,loach,chicken and other organisms to form a hybrid rice duck breeding model,and compared the differences in aboveground biomass of rice yield and maturity in rice-duck composite breeding mode. There are six treatments and one control in the experiment： rice-fish-duck,rice-fish-duck-duckweed,rice-loach-duck,rice-duck-loach...
