Abstract: For the purpose of resourceful utilization of the ginkgo leave residues(GLR), the effects of GLR mass ratios(0%, 10%, 20%, 30% and 40%)on aerobic composting of pig manure were studied in this paper. The results showed that the temperature in the composts added with 20% and 30% of GLR raised to its maximum value of 65 ℃ and 63 ℃ respectively in the third day, and their high temperature over 55 ℃ maintained for 7 days during composting. Only 28 days were spent for the main fermentation process(over 40 ℃)in the composts with 20% and 30% GLR, obviously less than that in the control compost added no GLR. After composting, the organic carbon content in all composts was 25%-28%, fitted the national standard of organic fertilizer(NY525-2012), and didn't present significant differences between the composts. Total nitrogen(TN)content in all composts was 2.26%-3.20%. The TN content in the compost with 20% GLR was 3.20% and increased by 41.5% compared with the control. Both C/N and T value(the ratio of the C/N at the end of composting to that at the beginning of composting)in all composts were fitted with the maturity standard of pig manure compost(C/N<20, T<0.6). The germination index(I_G)of corn was over 80% in the 28th day during composting for the composts with 20% and 30% GLR, while for the other composts over 35 days were spent. Comprehensively, the mass ratio of 20%-30% GLR was more benifit to the aerobic composting of pig manure.
