The invention discloses a method for improving acidified low-yield yellow clayed soil fields with pig manure charcoal. The method comprises adding pig manure charcoal into the acidified low-yield yellow clayed soil fields at a utilization rate of 1400-1600 kg per mu (=0.0667 hectares), thereby achieving the effects of improving soil properties, promoting growth of rice and improving the rice yield. According to the method for improving the acidified low-yield yellow clayed soil fields with the pig manure charcoal, by influencing and regulating the microflora structure inside rice root growth soil environment, the soil microorganism richness of rhizosphere soil and non-rhizosphere soil can be improved; under interaction of the pig manure charcoal and rice root systems, differences of the microflora structures of the rhizosphere soil and the non-rhizosphere soil can be produced, acid obstacles of the yellow clayed soil fields can be released and growth of rice can be promoted, and further the rice yield can be improved.
