Soil ripening method based on high-delta 13C-value microbial residual material

The invention provides a soil ripening method based on a high-delta 13C-value microbial residue material, which comprises the following steps: S1, applying the high-delta 13C-value microbial residue material and a biological bacterial fertilizer into plough layer soil, deeply ploughing, uniformly mixing, standing for 5-15 days, and keeping 50-60% of field capacity during the period; s2, applying humic acid organic fertilizer, organic waste and nitrogen fertilizer, deeply ploughing, uniformly mixing, standing for 20-45 days, adjusting the field moisture capacity and then sunning upturned soil in the period, and specifically, adjusting the field moisture capacity to be 100% at a time and then reducing and keeping the field moisture capacity to be 50-60%; s3, the fertilization step in the S2 is repeated for multiple times, and the weight ratio of the humic acid organic fertilizer to the organic waste to the nitrogen fertilizer applied each time is adjusted according to different plough layer soil textures; and t
