Effects of Straw Mulching Thickness on the Soil Health in a Temperate Organic Vineyard

Soil mulching is one of the common measures applied in organic agricultural production which could replace plastic films and protect environment. In order to fully evaluate effects different straw thicknesses on soil health, maize was mulched with 0 cm (CK), 2 cm, 4 6 surface assess temperature (ST) moisture (SM), pH, carbon (SOC), total nitrogen (TN), C/N, aggregates bulk density (SBD) a temperate vineyard. We found that had significant regulating effect, being elevated increasing thickness by 5.8%, 9.0% 11.1% compared CK. The SOC content increased 3.0%, 2.4% 2.3%. Although pH C/N significantly (p < 0.05) increased, they fluctuated mulch thickness. Straw also >2 mm particle size mean weight diameter (MWD) geometric (GMD). prolonged effect stability aggregates. has best for ecologically environmentally managing warm-temperate vineyards so it may have great application prospect global scale.
