Prevention method for bighead atractylodes rhizome soil-borne disease

Abstract

The invention relates to a prevention method for a bighead atractylodes rhizome soil-borne disease. According to the prevention method, symbiotic plants, namely chrysanthemum indicum, are adopted to prevent the bighead atractylodes rhizome soil-borne disease. The transplantation mode is one or any one combination of more than two kinds of intercropping, interplanting and crop rotation. An ecological planting method is adopted, bighead atractylodes rhizome and the chrysanthemum indicum are mixed and planted, planned crop rotation and intercropping are carried out, allelopathy of plants is used for preventing the bighead atractylodes rhizome soil-borne disease, the problem of pesticide residue due to the fact that pesticides are applied for insect and disease prevention when bighead atractylodes rhizome is produced is solved, morbidity of southern blight and root rot of bighead atractylodes rhizome is effectively reduced in production, green and safe production effects are achieved, and meanwhile, a new way is opened up for comprehensive utilization of chrysanthemum indicum.

Description

technical field [0001] The invention belongs to the technical field of Atractylodes atractylodes cultivation, and in particular relates to a method for preventing and treating soil-borne diseases of Atractylodes atractylodes. Background technique [0002] Soil-borne diseases refer to plant diseases caused by the infection of soil-borne pathogens, which belong to the category of root diseases. Infection pathogens include fungi, bacteria, actinomycetes, and nematodes. Among them, fungi are the main ones, which are divided into non-obligate parasitism and obligate parasitism. Non-obligate parasitism is an ectophytic root-infecting fungus, such as Pythium causing seedling rot and damping-off, and Rhizoctonia causing seedling blight. Obligate parasitism is a plant microtubular bundle pathogenic fungus, such as Fusarium oxysporum, Verticillium chrysogenum, etc., which cause wilting and death of seedlings. The severity of root disease is controlled by the composition and concent...

Problems solved by technology

[0004] The main ways to deal with soil-borne diseases in the production of Atractylodes macrocephala are: 1. Breeding excellent varieties, but the blindness of this phenotype selection, coupled with the lack of available resistant variety resources, long breeding time, high cost, and high resistance. Disease varieties are prone to degeneration, etc., which makes the cultivation and promotion of resistant varieties slow, and has not yet been applied on a large scale; 2. The use of chemical pesticides and biological pesticides, this method not only leads to the enhancement of pathogenic bacteria resistance, but also Residue pollution The environment is harmful to human health, and also greatly affects the quality of Atractylodes macrocephala; 3. Improve the soil microbial environment, increase the application of multi-effect organic fertilizers, bio-organic fertilizers, etc. However, the price of biological fertilizers is relatively expensive, and the nitrogen content of bio-organic fertilizers Phosphorus and potassium nutrients cannot supply the nutritional needs of crops in time

Although these methods can achieve the purpose of preventing and controlling soil-borne diseases of Atractylodes macrocephala to a certain extent, they are often accompanied by many adverse effects such as excessive pesticide residues and increased soil pathogenic bacteria.
