1. soak in warm water: soak the frozen soil in warm water, and the temperature should not be too high, so as not to cause soil structure damage or microbial death. Warm water can accelerate the melting of ice crystals in soil.
2. heating: using heating equipment (such as electric blanket, heating plate, etc.) to heat the soil can thaw quickly. However, it is necessary to control the temperature to avoid overheating.
3. Thawing in microwave oven: put the frozen soil in microwave oven and use the thawing function of microwave oven to heat it. This method can thaw quickly, but you need to pay attention to the power and time of microwave oven to avoid overheating.
