The law of the evolution of methane-producing ancient bacteria in the soil of the ancient terraced age of Longridge in 630.

The age sequence of rice soil in ancient terraces is a good material for studying the rise and fall of rice agriculture under the changes of ancient climate and environment.
the current construction of such historical events depends more on the chemical and chemical properties of ancient soils, and rarely involves the storage of microbial information.
microorganisms are important participants in soil development and are sensitive to global climate change and human activities.
researchers speculate that microbial information stored in rice soil in ancient terraces could be an indicator of the interaction process of reducing paleo-climate, paleo-environment and human agricultural activities.
Feng Youzhi, a researcher at the Nanjing Soil Research Institute of the Chinese Academy of Sciences, joined Li Shijie of the Institute of Geochemistry of the Chinese Academy of Sciences to study the evolution of methane-producing ancient bacteria in the 630 years since the end of the Yuan and the beginning of the Ming Dynasty, using the age sequence that has been formed in the ancient terraces of Longridge, Guangxi Province.
, the study shows that the quantity, diversity and community structure of methane-producing ancient bacteria in rice paddies are closely related to multiple scientific and chemical substitute indicators, and show the same law of change with farming methods and processes. The effects of events such as the
centennonal and ten-year scales of the Middle AgesXiaoiceChuan period, the Taiping Uprising and natural disasters on local rice paddies farming can be reflected in the changes in the diversity of methane-producing ancient bacteria communities.
this high correlation indicates that microbial information stored in ancient soils can be used as a new substitute index in environmental archaeology research and is expected to be included in the general research scope of environmental archaeology research.
the study was published in science bulletin.
