Three consecutive years of straw decomposition test was carried out with nylon bag to study the decomposition characteristics of rice straw in Western Heilongjiang. The results showed that, the decomposition of rice straw into stagnation period between every October to May the next year; the straw was into decomposition of from June to September. The change of the decay rate of rice straw is “fast - slow -slow”. On the first anniversary of decomposition, the rate of decay was greatly improved, the rate was 44.3%; on the second anniversary of decomposition, the rate of decay was relatively slow, the rate was 19.5%; on the third anniversary of decomposition, the change of decay was tends to be stable, the decomposing rate was 5.7%.
