Study on Composting Technique of Mixed Sawdust and Rice Husk as Media

Decomposition results of sawdust and rice husk mixed materials by single-factor test design were researched.The results showed that the composting of sawdust and rice husk mixtures could achieve higher temperature,and physical and chemical properties of decomposition media were improved,and soluble sugar were decomposed sharply,and cellulose contents decreased and EC value reduced.Sawdust and rice husk with ratio of 6:4 were decomposed more thoroughly.T value of C/N ratio should be less than 0.5 while organic waste composting were finished.
