Abstract
In order to explore the best working method of corn straw decomposition for field return under extreme cold temperature conditions in Northeast China. The orthogonal test method was used to test and analyze the decay of corn straw by using the factors of straw return depth, straw return amount, straw stalk part and decomposer concentration. The results showed that the most significant effect on the decomposition efficiency of cold land corn straw was the amount of straw returned to the field, followed by the concentration of decomposer and the depth of straw returned to the field, and the least effect was the straw part. Among them, the amount of straw returned to the field showed a negative correlation on the decomposition efficiency of cold land corn straw; the concentration of decomposer, the depth of straw returned to the field and the straw part showed a positive correlation on the decomposition efficiency of cold land corn straw. Under the conditions of this experiment, a small amount of straw accompanied by an additional application of decomposer was returned to the field in depth burial to best facilitate straw decomposition.
