Embodiment 1

[0022] A comprehensive soil treatment method for continuous cropping of Panax notoginseng, comprising the steps of:

[0023] 1) Soil fumigation includes in turn:

[0024] Pre-fumigation treatment: deeply plow the continuous cropping field planted with Panax notoginseng, dry it in the sun, and then rotary till the soil so that the diameter of the soil particles is less than 2cm;

[0025] Fumigation treatment: inject the chloropicrin stock solution into the soil, the depth of injection of the chloropicrin stock solution into the soil is 15cm, the distance between two adjacent injection points is 30cm, and the injection volume is 2ml. After the injection is completed, compact the injection hole , and then cover the soil with a plastic film, and make the soil fit the film, and compact the edges. The injection depth and injection distance can make all areas of the entire planting soil be fumigated;

[0026] Post-fumigation treatment: post-fumigation treatment is to remove the fumi...

Embodiment 2

[0031] A comprehensive soil treatment method for continuous cropping of Panax notoginseng, comprising the steps of:

[0032] 1) Soil fumigation includes in turn:

[0033] Pre-fumigation treatment: Deep plow the continuous cropping field planted with Panax notoginseng, dry it in the sun, and then rotate the soil so that the diameter of the soil particles is less than 1.5cm;

[0034] Fumigation treatment: inject the chloropicrin stock solution into the soil, the depth of injection of the chloropicrin stock solution into the soil is 30cm, the distance between two adjacent injection points is 15cm, the injection volume is 3ml, and the injection is compacted after the injection is completed. , and then cover the plastic film above the soil, make the soil fit the film, and compact the edges;

[0035] Post-fumigation treatment: The post-fumigation treatment is to remove the fumigation film after fumigation of the cover film for 15 days, and deflate for 10 days. After the gas volatil...

Embodiment 3

[0040] A comprehensive soil treatment method for continuous cropping of Panax notoginseng, comprising the steps of:

[0041] 1) Soil fumigation includes in turn:

[0042] Pre-fumigation treatment: Deep plow the continuous cropping field planted with Panax notoginseng, dry it in the sun, and then rotate the soil so that the diameter of the soil particles is less than 1.6cm;

[0043] Fumigation treatment: inject the chloropicrin stock solution into the soil, the depth of injection of the chloropicrin stock solution into the soil is 23cm, the distance between two adjacent injection points is 20cm, the injection volume is 2.5ml, and the injection hole is compacted after the injection hole, then cover the soil with a plastic film, and make the soil fit the film and compact the edges;

[0044] Post-fumigation treatment: The post-fumigation treatment is to remove the fumigation film after fumigation of the cover film for 18 days, and deflate for 8 days. After the gas volatilizes, th...

Abstract

The invention discloses a pseudo-ginseng continuous cropping soil comprehensive treatment method which comprises the following steps of 1, performing soil fumigation; 2, applying base fertilizer; 3, disinfecting secondarily; 4, top dressing biocontrol bacterium and humate fertilizer. The pseudo-ginseng continuous cropping soil comprehensive treatment method has the beneficial effects that nitrochloroform is utilized as a pseudo-ginseng continuous cropping soil fumigation agent to effectively kill creatures such as fungi, bacteria and insects; calcium cyanamide can slowly release nitrogen fertilizer, reduce soil-borne disease, reduce soil insects, supplement calcium and improve soil; the nitrochloroform and the calcium cyanamide both can be resolved in soil and are free of residue; the biocontrol microorganism can be colonized in the soil and at the roots of the pseudo-ginseng, and root rot pathogenic bacteria of the pseudo-ginseng are prevented from invading by occupying effective ecological niches, generating antibacterial substances and the like; humic acid water-soluble fertilizer can achieve fertilizer synergia, improve the soil and stimulate crop growth. The pseudo-ginseng continuous cropping comprehensive treatment method can enable the emergence rate of pseudo-ginseng seed branches in continuous cropping soil to be 95% or more, and the seedling survival rate to be 80% or more.

Description

technical field [0001] The invention relates to a soil treatment method for continuous cropping of notoginseng, in particular to a comprehensive treatment method for continuous cropping soil of notoginseng. Background technique [0002] Panax notoginseng is a herbaceous plant of the Araliaceae ginseng genus. Panax notoginseng has special requirements for climate, soil and other growth environments, and it mainly grows in areas with an altitude of 1200-2200m in southwest China. The traditional planting areas are mainly in Wenshan, Yunnan and Guangxi. [0003] Generally, the continuous cropping land that has been planted with Panax notoginseng needs to be continuously rotated with other crops for more than 10 years, or even 30 years before planting Panax notoginseng again, and the interval is longer; obstacles to continuous cropping of Panax notoginseng seriously restrict the development of Panax notoginseng industry and affect Wenshan as the main production area It is a tech...
