Through a series of soil investigation and fertilizing experiment, the relationship between crop yield and the soil fundamental fertility has been revealed in the clayey carbonate meadow soil.
The order of semi-hydromorphic soil contains the great groups of Chao soil and mountain scrubby-meadow soil.
Selected soils are meadow soil, Black Calcium soil, and meadow alkali soil, respectively.
Saline meadow soil distributed in the micro basin, and sodic alkaline soil in micro slope or micro flat.
Planting host plants significantly influenced the bacterium capacity of soil on black and lessive soils, but less influence on sandy and meadow soils.
