Treatment method of continuous cropping soil

The invention relates to a treatment method of continuous cropping soil, and belongs to the technical field of soil improvement. Harmful bacteria in the continuous cropping soil are killed by high-temperature steam treatment, then struvite, mushroom spawn culture medium waste materials, sawdust, soybean root nodule and the like are used for fermentation, nutrients are activated in the growth process of soybean rhizobia, rhizobium fertilizer is prepared, and chemical elements of N and P accumulated in the soil are activated and balanced; then activated carbon in rice husks, silicon dioxide composite dolomite, fly ash and the like are used, so that the physical properties of the fertilizer are improved, the loss of fertilizer nutrients is reduced, the utilization rate of the fertilizer is improved, the buffering performance of the soil is enhanced, harmful elements in the soil are adsorbed, heavy metal pollution of the soil is treated, soil salinity and acidification are reduced, and soil continuous cropping ob
