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...

Embodiment 2

[0037] A kind of notoginseng continuous cropping soil flame treatment method, comprises the steps:

[0038] 1) Treatment before incineration

[0039]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 40cm deep, and dry the plowed land for 15 days, then break the soil, and randomly select 3 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 9%, 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 9%;

[0040] 2) Incineration treatment

[0041] 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 400°C to make the soil particles fall to the ground. The ...

Embodiment 3

[0047] A kind of notoginseng continuous cropping soil flame treatment method, comprises the steps:

[0048] 1) Treatment before incineration

[0049] 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 35cm deep, and dry the plowed land for 15 days, then break the soil, and randomly select 5 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 8%, 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 8%;

[0050] 2) Incineration treatment

[0051] The crushed soil is plowed again, and more than 95% 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 350°C, so that the soil particles fall to the ground The...

Abstract

The invention provides a radix notoginseng continuous cropping soil flame treatment method which comprises the following steps: (1) performing incineration pretreatment; (2) performing incineration treatment; and (3) planting. The radix notoginseng continuous cropping soil flame treatment method has the beneficial effects that a physical method for incinerating the radix notoginseng continuous cropping soil by high-temperature flame is utilized, so pathogenic microorganism fungi, underground pests and weed in the radix notoginseng continuous cropping soil can be effectively killed, any residues do not exist, the time is short, the structure and the physicochemical properties of the soil are not influenced, and the treated soil has small and uniform granularity; and the seedling emergence rate and the seedling survival rate of radix notoginseng seedlings in the continuous cropping soil can be effectively increased, and the growth state of the radix notoginseng plants can be effectively enhanced.

Description

technical field [0001] The invention relates to a soil treatment method for continuous cropping of notoginseng, in particular to a flame treatment method for continuous cropping soil of notoginseng. Background technique [0002] The obstacle of continuous cropping of Panax notoginseng means that after planting a crop (2-3 years) of Panax notoginseng in the same soil, if Panax notoginseng is planted again, even under normal cultivation and management conditions, there will be severe root rot of Panax notoginseng and plant growth Phenomenon of weakening, lower yield and lower quality. The causes of continuous cropping obstacles of Panax notoginseng mainly include deterioration of soil physical and chemical properties, nutritional imbalance, accumulation of autotoxic allelochemicals, and outbreak of soil-borne diseases. Wenshan, Yunnan is the authentic and main producing area of ​​Sanqi. In recent years, due to the obstacles of continuous cropping of Sanqi, the land capable of...
