Calcium cyanamide (lime nitrogen) is a new type of soil decontamination agent with the functions of insecticidal and sterilization, purifying the soil and restoring the physiological activity of the soil. Mainly used for soil disinfection, prevention of heavy crop accumulation of nematodes, dead tree seedlings and other soil-borne disease, continuous cropping as toxic disease and soil over-fertilization caused by salt accumulation, calcium deficiency and other physiological diseases caused. It not only has good control effects on crop root rot, bacterial wilt, but also provides necessary calcium and nitrogen fertilizers for crop growth. It is an ideal treatment agent for soil disinfection. The high temperature stuffy shed disinfection method shown in Figure:
