Abstract: This experiment took cow dung as the main raw material, peanut shell (T1), corn stover (T2) and corn shell (T3) as the additives, and supplemented with special em agent for livestock manure decomposing to discuss the different source conditioning agents for high temperature of cow dung, which expected to provide a scientific basis for the scientific utilization of solid waste and the environmental pollution caused by waste. The results showed that the composting temperature, NH+4-N content, pH, EC value and seed germination index (GI) of T1, T2 and T3 were all in accordance with compost maturity requirements. Organic matter content (135.0 g/kg), total nitrogen content (6.7 g/kg), total phosphorus content (5.0 g/kg), and total potassium content (8.1 g/kg) of T2 treatment were significantly (P<0.05) higher than T1 treatment (118.4 g/kg, 5.2 g/kg, 4.6 g/kg, 6.5/kg) and T3 treatment (122.2 g/kg, 4.5 g/kg, 4.4 g/kg, 6.1 g/kg). The time required to drop to room temperature for the T3 treatment was the shortest, which was 32 d, and that for T2 and T1 treatments were 58 d and 48 d, respectively. Considering the composting process, compost product traits, carbon source and cost, it was recommended to use corn husk as the carbon source conditioning agent for high-temperature aerobic composting of cattle manure in actual production.
