Embodiment 1
[0027] A kind of notoginseng continuous cropping soil flame treatment method, comprises the steps:
[0028] 1) Treatment before incineration
[0029] Remove the diseased residues and pine needles on the surface of the continuous cropping land planted with Panax notoginseng, then plow the continuous cropping land 20cm deep, and dry the plowed land for 20 days, then break the soil, and randomly select 4 soil samples , measure the water content in the soil with a portable soil moisture detector, when the water content in the soil is greater than 10%, dry the continuous cropping land, and test the water content in the soil every day until the water content in the soil is less than 10%;
[0030] 2) Incineration treatment
[0031] The crushed soil is plowed again, and more than 90% of the plowed soil particles have a diameter of less than 1cm, and the plowed soil particles are repeatedly burned with a high-temperature flame at 300°C to make the soil particles fall to the ground. T...
