Abstract

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 obstacles are overcome.

Description

technical field [0001] The invention relates to a continuous cropping soil treatment method, which belongs to the technical field of soil improvement. Background technique [0002] Soil is the most basic means of production for human beings and the material basis for human survival. In our country, land resources are not only very limited, but also a considerable proportion of soils have obstacle factors due to soil-forming factors or human factors, including erosion, poor texture, poor structure or arability, salinity, acidification, toxic substance pollution, There are bad soil layers in the soil that hinder the growth of plant roots, too much or insufficient soil moisture, low fertility or imbalance of nutrients, etc. [0003] Due to the continuous planting of the same species or the same family of crops, the excessive application of chemical fertilizers or partial application of chemical fertilizers in the production of facility vegetables has caused problems such as ac...
