Abstract:

To study the influence of rice field integrative cultivation on soil, this article summarized the research progress on integrated rice farming models both domestically and internationally in recent years, and compared them with rice monoculture. The effects of different modes of rice field integrative cultivation on the ecological environment of paddy soil were analyzed from five aspects: soil fertility, soil microorganisms, soil enzyme activity, soil heavy metal and soil greenhouse gas emission. The results showed that compared to rice monoculture, integrated rice farming significantly improved soil quality, increased soil nutrients, optimized soil structure, promoted soil biodiversity, reduced heavy metal accumulation, and reduced greenhouse gas emissions. These findings provided important references for agricultural production and demonstrate the potential of integrated rice farming models in promoting sustainable agricultural development and ecological environment protection.

Key words: rice field integrative cultivation, soil microorganisms, soil heavy metals, greenhouse gas emissions
