摘　　要：为探索稻蟹生态种养的最优模式,对盘山县常规水稻单一种植(RM)、稻蟹生态种养模式(ERC)和稻蟹生态种养优化模式(OERC)三种模式下水稻产量及输出产品综合效益进行了比较分析。结果表明,三种种养模式的水稻产量未呈现显著差异,ERC和OERC两种生态种养模式都显著提升了经济效益,与ERC相比,OERC对河蟹产出量和规格提高效果明显,亦可有效减轻纹枯病的发生,并对于易倒伏水稻品种降低倒伏率作用显著,是兼顾经济效益和生态效益的稻蟹生态种养优化模式。In order to explore the optimal ecological cultivation model of rice and crab,the rice yield and the comprehensive benefits of rice output under conventional rice mono-cultivation(RM),rice and crab ecological cultivation(ERC)and rice and crab ecological cultivation optimization(OERC)in Panshan County were compared and analyzed.The results showed that there was no significant difference in rice yield among the three cultivation modes,and the two ecological cultivation modes of ERC and OERC significantly improved the economic benefits.Compared with ERC,OERC significantly improved the yield and size of crab,effectively alleviated the occurrence of dry wilt,and significantly reduced the lodging rate of rice varieties prone to lodging.It is an optimization model of ecological cultivation of rice and crab that takes into account both economic and ecological benefits.
