Research Progress in Effects of Farmland Management on Lignin Accumulation and Transformation in Soil
Lignin,as an important component of soil organic carbon,has a slow decomposition process that not only promotes the long-term accumulation and stabilization of soil organic carbon,but also profoundly affects soil fertility,ecological function,and carbon dynamic equilibrium mechanism.In recent years,the influence of different farmland management measures on the accumulation and transformation of lignin in soil has become a research hotspot.This paper analyzes and elucidates the characteristics of lignin accumulation and transformation in soil,reviews the latest research progress in the influence of land use change,tillage methods,fertilization,and straw return on lignin accumulation and transformation in soil,and proposes the direction for future research.The aim is to provide reference for research and practice in related fields.
