Correlation analysis of soil total organic carbon with colonization rate, hyphal lodge density, and soil physical and chemical properties under inoculation with different AM fungi* indicated P<0.05, ** indicated P<0.001; red color represented positive correlation, the darker the color, the stronger the positive correlation; blue color represented negative correlation, the darker the color, the stronger the negative correlation. The larger the sphere, the greater the correlation value.
