Simple method for co-thoroughly decomposing and fertilizing wheat straw and livestock and poultry manure

The invention relates to the technical field of agriculture, and provides a simple method for co-decomposing and fertilizing wheat straw and livestock and poultry manure, which comprises the following steps: S1, paving a fermentation and decomposition bed: sequentially paving an anti-seepage felt layer, a wheat glume layer and a corn straw layer from bottom to top from the ground to obtain the fermentation and decomposition bed; s2, stacking: firstly spreading the chopped wheat straws on a fermentation and decomposition bed, spreading the chopped wheat straws at a height of 20-30cm each time, then spraying livestock and poultry manure which is 1-1.5 times of the mass of the chopped wheat straws on the chopped wheat straws, then spraying a deodorant, and repeating the steps until the stacking height reaches 1.5-2m to form a final stack; s3, the stack is fermented and decomposed, and the wheat straw organic fertilizer is obtained. By means of the technical scheme, the problems that in the prior art, straw decom
