摘　　要：该研究探索了稻田养鳖后对于水稻分蘖数、干物质量和产量的影响,将稻鳖共生稻田(R-T)与常规种植稻田(R-M)进行对比。结果显示,在水稻抽穗期末,稻鳖共生模式(R-T)的水稻分蘖数显著高于稻单种模式(R-M)(P<0.05);在水稻抽穗期,稻鳖共生模式(R-T)的水稻干物质量显著高于稻单种模式(R-M)(P<0.05);稻鳖共生模式(R-T)的有效穗粒数和稻谷产量显著高于稻单种模式(R-M)(P<0.05)。其中稻谷产量增加了约有19.32%。在稻田中养殖鳖,能够有效提升稻谷产量。This study explored the effects of rice turtle co-culture on tiller number,dry matter quality and rice yield,the rice turtle co-culture(R-T)and conventional rice mode(R-M)were compared.The result shows that:In rice heading the final,the rice turtle co-culture mode(R-T)of rice tiller number is significantly higher than conventional rice mode(R-M)(P<0.05);At heading stage of rice,rice turtle co-culture mode(R-T)of dry matter of rice quality is significantly higher than conventional rice mode(R-M)(P<0.05);rice turtle co-culture mode(R-T)effective ear grain number and grain yield of rice is significantly higher than the conventional rice mode(R-M)(P<0.05).The grain yield increased by about 19.32%.Farmed turtles in the paddy fields,can effectively improve grain yield.
