Abstract:
In order to investigate the effects of different composting conditions on the degradation rate of organic garden carbon substances,the amount of bacteria,vegetation volume ratio(C/N) and turning frequency as the experimental factors,a compost test with an orthogonal experimental design L9(34) was conducted.The variation trends in temperature,total organic carbon concentrations,lignin,cellulose and hemi-cellulose contents,humus and compositing of compound fertilizer during composting were analysis.The results showed that adjustment of C/N ratio,turning frequency and the bacterial reagent benefited the degradation of organic garden carbon substances and the acceleration of maturity,and improved the compost quality.The addition of bacterial reagent was confirmed the most important factor affecting the degradation of organic garden carbon substances and the acceleration of maturity.The conditions of 4% addition of bacterial reagent,2∶1 vegetation volume ratio (C/N=30) and one day turns mow once was the best for the composting.
