Abstract:

Composting experiment was carried out by outdoor high-temperature aerobic compost technical, using landscaping wastes in Xiangshan Park of Beijing as composting material. The days of the high temperature period, EC value, pH value, C/N ratio and germination index (GI) were analyzed during the aerobic composting, and the different effects was analyzed when charcoal matter and wood vinegar, compared with the effective microorganisms (EM) and blank space group. The results showed that, both charcoal matter and wood vinegar would promote the process of composting of landscaping waste. Mainly as follows, the temperature rise and the days of the high temperature period were promoted by charcoal matter and wood vinegar. The pH value and EC value of the compost will be affected by charcoal matter and wood vinegar. The C/N ratio of descent can be achieved by charcoal matter and wood vinegar. It reached to 44.50% and 41.44%, which was slightly lower than the EM group (45.61%) and higher than the blank space contrast (32.51%), and the T value was all below 0.6. The degradation of the plant toxic substance in the compost was subjected to be accelerated by adding charcoal matter and wood vinegar, and the GI was up to 97.27% and 98.03% respectively.
