By using different ratios of wood vinegar fertilizer in camphor forest, the changes of relevant indexes of soil microbial number, chemical properties, soil enzyme activity and chlorosis index was studied. The results showed that all the six different ratios of wood vinegar fertilizer could improve chemical properties of soil, increase soil microbial quantity, enhance soil enzyme activity and control etiolation of camphora trees. Compared with contrast, the ratio with low concentration of wood vinegar and low organic fertilizer treatment was not as good as other treatments in inhibiting soil microorganism, improving chemical properties and controlling etiolation. Based on an overall consideration of various factors, the ratios with middle or low concentration of wood vinegar added charcoal powder (wood vinegar: charcoal powder ratio = 1︰5 ( V / M ) and middle or high organic fertilizer were better in use of urban afforesting and greening.
