Embodiment 1

[0028] The control method of Codonopsis root rot comprises the following steps:

[0029] Step 1, soil treatment:

[0030] 1) Flame treatment: Deep plow the land where Codonopsis pilosula needs to be planted and dry it in the sun, then break the deep plowed soil so that 80% of the soil particles are less than 1cm, and then burn the broken soil at an overfire temperature of 400°C , until the ground temperature of the soil is 55°C;

[0031] 2) Chemical treatment: spread a layer of Artemisia annua on the soil after soil flame treatment, spread 2kg of Artemisia annua per square meter of soil, then cover with plastic film, seal the edge of the plastic film with soil, open the plastic film after drying for 20 days, Then spray 500 times of liquid of 25% carbendazim powder to the land after airing, wherein every square meter of land sprays 500 times of liquid of 25% carbendazim powder of 1kg;

[0032] Step 2, seed treatment:

[0033] 1) Seed selection: select seeds with full fruit g...

Embodiment 2

[0040] Step 1, soil treatment:

[0041] 1) Flame treatment: Deep plow the land where Codonopsis pilosula needs to be planted and dry it in the sun, then break the deep plowed soil so that more than 85% of the soil particles are less than 0.5cm, and then put the broken soil through a fire at 500°C Temperature burning until the ground temperature of the soil is 45°C;

[0042] 2) Chemical treatment: spread a layer of Artemisia annua on the soil after soil flame treatment, spread 3kg of Artemisia annua per square meter of soil, then cover with plastic film, seal the edge of the plastic film with soil, open the plastic film after drying for 30 days, Then spray 500 times of liquid of 25% carbendazim powder to the land after airing, wherein every square meter of land sprays 500 times of liquid of 25% carbendazim powder of 0.5kg;

[0043] Step 2, seed treatment:

[0044] 1) Seed selection: select seeds with full fruit grains and no diseased seedlings;

[0045] 2) Disinfection: Soak...

Embodiment 3

[0051] Step 1, soil treatment:

[0052] 1) Flame treatment: Deep plow the land where Codonopsis pilosula needs to be planted and dry it in the sun, then smash the deep plowed soil so that more than 90% of the soil particles are less than 1cm, and then pass the crushed soil through a fire temperature of 450°C Incinerate until the ground temperature of the soil is 50°C;

[0053] 2) Chemical treatment: spread a layer of Artemisia annua on the soil after soil flame treatment, spread 2.5kg of Artemisia annua per square meter of soil, then cover with plastic film, seal the edge of the plastic film with soil, open the plastic film after drying for 25 days , and then spray 25% carbendazim powder 500 times liquid to the land after drying, wherein 0.7kg of 25% carbendazim powder 500 times liquid is sprayed per square meter of land;

[0054] Step 2, seed treatment:

[0055] 1) Seed selection: select seeds with full fruit grains and no diseased seedlings;

Abstract

The invention discloses a method for prevention and control of Codonopsis pilosula root rot. The method comprises soil treatment which means that flame treatment and pharmaceutical treatment are conducted on soil 30-40 days before sowing. The method disclosed by the invention has the beneficial effects that the soil used for Codonopsis pilosula planting is treated, so the content of harmful bacteria in the soil is effectively reduced; through secondary treatment of the soil, nutrients in the soil are maintained, and the residual harmful bacteria in the soil are further killed; through selection and virus killing of seeds, fertilizers applied in the soil, and work of a drainage ditch and sterilization, Codonopsis pilosula planted with the method disclosed by the invention can keep good growing situations, and the morbidity of root rot can be reduced effectively; and because of the flame treatment, the method disclosed by the invention can also kill the harmful bacteria during operations of continuous cropping soil and thus the survival rate of the Codonopsis pilosula planted in the continuous cropping soil can be increased.

Description

technical field [0001] The invention relates to a method for preventing and treating Codonopsis pilosula, in particular to a method for preventing and treating Codonopsis root rot. Background technique [0002] Codonopsis Codonopsis Codonopsis Campanulaceae is a perennial herb with latex. The stem base has many tumor-like stem scars, the root is often hypertrophic and spindle-shaped or spindle-cylindrical, the stem is twisted, sterile or apex flowering, yellow-green or yellow-white, leaves alternate on the main stem and side branches, and the petioles are sparse and short Prickly, leaves ovate or narrowly ovate, with wavy blunt serrate edges, green above, gray-green below, flowers solitary on branches, alternate or nearly opposite to petioles, corolla superior, broadly seeded, lobes equitriangular , anthers are elongated, with many seeds, ovate, flowering and fruiting from July to October. [0003] In the initial stage of Codonopsis root rot, the lower fibrous roots or l...
