Prevention and control method for continuous cropping barriers of atractylodes macrocephala

Abstract

The invention discloses a prevention and control method for continuous cropping barriers of atractylodes macrocephala. The method comprises the steps of land selection, plowing, seed selection and seedling raising, field management, flower bud removing and harvesting, wherein a land with an appropriate slope after first-stubble atractylodes macrocephala is harvested and before the second-stubble atractylodes macrocephala is cultivated is selected for planting corn and soybeans; after preceding plants are harvested and turned over, sheep dung and cow dung are uniformly spread on the plants, then quick lime is spread, and full decomposing, ploughing and drying are carried out; a soil continuous cropping agent is added before transplanting, and ploughing is carried out again; then a broad-leaf high-pole atractylodes macrocephala strain is selected, from first frost to beginning of winter, the atractylodes macrocephala without diseases and insect pests and with plump bud heads at the top end and the weight of 9-12 grams is selected as seed atractylodes macrocephala, then 8000-15000 of basic seedlings are planted on ridges every mu and intercropped with corn; finally, field weed prevention and control, fertilization and field drainage and irrigation are carried out. By using the method, important traits such as plant height, crown breadth, stem diameter, leaf length, leaf width andbranching number are significantly improved, the occurrence of the soil borne root rot is reduced, and the content of atractylenolide is increased.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine planting, in particular to a method for preventing and controlling Atractylodes macrocephala continuous cropping obstacles. Background technique [0002] Atractylodes macrocephala Koidz (Atractylodes macrocephala Koidz.) is a perennial herb of the Asteraceae Atractylodes genus, up to 60cm high, with nodular rhizomes. The dried rhizome is used as medicine, which is one of the bulk medicinal materials commonly used in my country. It was first recorded in "Shen Nong's Materia Medica", and it was listed as the top grade. It can dry dampness and invigorate the spleen, insufficiency of the spleen, lack of food, indigestion, chronic diarrhea, edema, spontaneous sweating, and miscarriage. The chemical and medicinal components of Atractylodes Rhizome mainly include volatile oil of Atractylodes Rhizome, lactone compounds, polysaccharides of Atractylodes Rhizome, glycosides, amino acids, and trac...

AI Technical Summary

Problems solved by technology

In order to avoid continuous cropping of Atractylodes macrocephala, local drug farmers often transplant the one-year-old Atractylodes macrocephala seedlings to the soil that has not been planted Atractylodes macrocephala for planting, and the soil that has been planted Atractylodes macrocephala usually takes 3 to 5 years to replant, only relying on the conventional crop rotation method, It has been unable to meet the market demand, and caused a great waste of land resources, affecting the sustainable development of Atractylodes rhizome production; in addition, most drug farmers also ensure the production of Atractylodes rhizome through long-term application of fertilizers and frequent spraying of pesticides, resulting in excessive pesticide residues in Atractylodes rhizome, and the medicinal The quality declines, and pollutes water bodies and farmland soil, destroys the local ecological environment, and will eventually endanger human health
