周丛生物在稻田生态系统中的作用研究进展

Research Progress about the Effects of Periphyton on Paddy Field Ecosystem

稻田中普遍存在的周丛生物对稻田生态环境和水稻生长产生了显著影响,但是缺少系统的总结与分析。基于此,结合近年国内外周丛生物相关研究,总结了周丛生物对水-土界面理化性质、重金属、氨挥发以及水稻生长关键期的作用;提出未来研究应更关注稻田土壤表面的周丛生物、资源循环利用、工艺技术、基础理论等方面。以期深入了解周丛生物在稻田生态系统中的作用,进而为周丛生物管理和水稻生长优化提供理论参考。

Periphyton is ubiquitously distributed in paddy fields,and has a significant impact on the field ecological environment and rice growth.However,the underlying mechanisms are not fullyunderstood.Here,we reviewed the effects of Periphyton on the physical and chemical properties of the water-soil interface,heavy metals,ammonia volatilization,and the critical period of rice growth.The following prospects should be paid more attention in future studies:Periphyton on the surface of the paddy soil,resource recycling,process technology,basic theory.Future research should provide theoretical reference for Periphyton management and optimization of rice growth,for better understanding the effects of Periphyton on Paddy Field Ecosystem.
