The geological structure influenced the Sichuan red strata. the weatheringproduct and weathering strip's formation are analyzed. The red strata is a complex mechanics medium.
Among them the paddy soil developed from the weatheringproduct of limestone has much higher nutrient contents than the paddy soils developed from river alluvium and Quaternary Red Clay does.
Application: Regulating reservation rate of light transmittance after UV weathering test to simulate practical application progress, which guarantees the product maintaining the stable performance.
