“excrement-fertilizer orchard” planting and breeding circulation method suitable for red soil hilly regions in the south

Abstract

The present application discloses an “excrement-fertilizer-orchard” planting and breeding circulation method suitable for red soil hilly regions in the South, belonging to the technical field of agricultural resource recycling. The “excrement-fertilizer-orchard” planting and breeding circulation method suitable for red soil hilly regions in the South disclosed in the present application realizes efficient resource recovery of livestock waste through solid-liquid separation, layered composting (including Trichoderma), precise drip irrigation of biogas slurry and year-round living grass mulching in orchard. The organic matter content of compost is ≥40%, and the EC of biogas slurry after dilution is ≤2.0 mS / cm, which replaces 30% of chemical fertilizers; the annual increase of soil organic matter is ≥0.5%, and the soluble sugar content of fruits is increased by 15-20%. The present application has both ecological benefits and economic benefits, and is suitable for popularization in orchards in red soil hilly regions.
