A kind of Atractylodes macrocephala anti-cropping agent

Abstract

The invention relates to a continuous cropping obstacle resisting agent for largehead atractylodes rhizome. The continuous cropping obstacle resisting agent is prepared from raw materials in parts by weight as follows: 65-100 parts of chrysanthemum indicum fertilizer, 30-50 parts of chemical fertilizer and 40-60 parts of organic fertilizer, wherein the chrysanthemum indicum fertilizer comprises chrysanthemum indicum steam and leaf ground substances or chrysanthemum indicum extract components. The chrysanthemum indicum and the extract of the chrysanthemum indicum in the continuous cropping obstacle resisting agent contain efficacy factors for disease-resistant induction and the like and have synergistic effect with components of the resisting agent, inhibition of continuous crop of largehead atractylodes rhizome by secretion generated in the growing period of the preceding crop of largehead atractylodes rhizome is eliminated effectively, harmful substances, damaging growth of largehead atractylodes rhizome, in soil are degraded, normal growth of largehead atractylodes rhizome is promoted, continuous cropping obstacle resistance is realized, and continuous cropping obstacle resisting agent of largehead atractylodes rhizome is avoided. Largehead atractylodes rhizome planting test results prove that rotation of crops can be avoided, diseases are reduced, the yield can be increased, and the continuous cropping obstacle resisting agent has remarkable effect on application to continuous cropping obstacle resisting planting of largehead atractylodes rhizome.

Description

technical field [0001] The invention belongs to the technical field of Atractylodes atractylodes cultivation, and in particular relates to an Atractylodes atractylodes anti-repeat cropping agent. Background technique [0002] Atractylodes macrocephala is one of the bulk of commonly used Chinese medicinal materials in my country. It is a perennial herb that likes cool climates and is afraid of high temperatures. The main reasons for continuous cropping and heavy cropping of Atractylodes macrocephala to reduce yield: (1) Soil deterioration and nutrient imbalance; mainly because Atractylodes macrocephala has a certain selectivity to absorb nutrients in the soil, and absorbs more phosphorus, potassium, molybdenum, boron and other elements, Continuous cropping of Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizome year after year will inevitably result in the lack of some nutrient elements and the imbalance of nutrients in the soil, which will affe...

The main reasons for continuous cropping and heavy cropping of Atractylodes macrocephala to reduce yield: (1) Soil deterioration and nutrient imbalance; mainly because Atractylodes macrocephala has a certain selectivity to absorb nutrients in the soil, and absorbs more phosphorus, potassium, molybdenum, boron and other elements, The continuous cropping of Atractylodes macrocephala year after year will inevitably lead to the lack of certain nutrients and the imbalance of nutrients in the soil, which will affect the growth and development of Atractylodes macrocephala and reduce the yield

(2) Increased damage from diseases and insect pests; due to continuous cropping, some soil-borne diseases and insect pests and various pests and diseases that remain on the stumps of Atractylodes macrocephala in the field, a large number of pathogenic bacteria and insect sources remain in the soil, resulting in aggravated diseases of Atractylodes macrocephala year by year

(3) Accumulation of toxic substances; during the growth and development of Atractylodes macrocephala, the secretions of its roots and other parts of the plant will inhibit the growth of Atractylodes atractylodes, and even cause poisonous damage to Atractylodes atractylodes

In order to counteract the continuous cropping obstacle of Atractylodes atractylodes in China, crop rotation is still adopted, which cannot improve the land utilization rate and brings great difficulties to the specialization and intensification of Atractylodes atractylodes planting
