What are the hazards of calcium cyanamide soil solarization? These usage risks you need to understand

Calcium cyanamide, also known as calcium cyanamide, is a very strong dual-purpose pesticide and fertilizer soil disinfectant and fungicide, generally used in greenhouses, but because it has a certain toxicity, attention must be paid when applying it. So what are the hazards of calcium cyanamide soil solarization?

1. What are the hazards of calcium cyanamide soil solarization?

When calcium cyanamide is used for soil solarization, the odor released by calcium cyanamide and the cyanamide produced by its decomposition can cause certain harm to the human body, so when applying it, a mask must be worn, work clothes must be worn, and one must stay away from livestock living areas. After application, alcoholic beverages must not be consumed within 24 hours, to avoid adverse chemical reactions such as chest tightness and breathlessness.

2. How is calcium cyanamide used for soil solarization?

Spread chopped straw or wheat straw on the ground surface (1 kg per sq m) together with calcium cyanamide (0.1 kg per sq m), mix thoroughly with the soil (rotary till twice with a rotary tiller), form ridges (ridge width 60 cm, height 40 cm), and cover with plastic film, fill the furrows with water, and seal the facility or greenhouse tightly. During the day, the surface temperature can reach 70°C, and the temperature of the soil 20 cm deep is 40-50°C. After lasting 20-30 days, it can achieve the effects of soil disinfection and salt reduction.
