稻蟹共作对田间生态环境与水稻生长的影响研究进展

Effects of rice-crab coculture on field ecological environment and rice growth: A review

稻蟹共作模式是我国较成熟的稻田综合种养模式。由于"蟹"的加入,稻蟹共作带来较高经济价值的同时,对田间生态环境和水稻生长也带来显著影响,但对其影响结果及原因缺少系统总结与分析。基于此,本文结合近年国内外稻蟹共作相关研究,总结了稻蟹共作对田间气体排放、养分循环及生态效益的影响,进一步探讨稻蟹共作对水稻品种选择、田间水肥管理及水稻产量品质的影响。提出未来研究应更关注整体生态环境效应,研究方法应加强大范围田间实验与小规模模拟实验结合,研究内容应加强机理研究,深入稻蟹共作整体效应,研究周期应加强长期定位研究,研究方向应关注协同、优质、高效等问题。以期深入了解稻蟹共作对田间生态环境及水稻生长的影响,进而为稻蟹共作理论创新与技术突破提供理论支撑。

Rice-crab coculture is a mature model of integrated aquaculture system in China.Rice-crab coculture can produce higher economic value and also has a significant impact on the field ecological environment and rice growth.However,the underlying mechanisms are not fully understood.Here,we reviewed the effects of rice-crab coculture on field gas emission,nutrient cycling,and ecological benefit.We further focused on rice variety selection,water and fertilizer management,rice yield and quality.The following prospects should be paid more attention in future studies:integrative ecological environment;the combination of large-scale field experiment and small-scale simulation experiment;mechanism and the overall effect of rice-crab coculture;long-term field research.Future research should focus on synergy,quality and efficiency,for better understanding the effects of rice-crab coculture on ecological environment and rice growth.
