Problems solved by technology

Years of continuous cropping have led to the increase of diseases and insect pests year by year, character degradation, quality decline, and yield stagnation, seriously affecting the sustainable development of the angelica industry.
Many scholars have pointed out: "Soil-borne diseases are the most important factor causing the continuous cropping obstacles of Angelica sinensis", among which root rot is one of the most serious diseases, which leads to a serious decline in the yield and quality of medicinal materials, seriously affecting the yield and quality of authentic medicinal materials Angelica sinensis. The quality and planting efficiency have dropped significantly, causing great losses to drug farmers and seriously dampening the enthusiasm of drug farmers
In addition, most of the angelica production areas are distributed in high-altitude and remote mountainous areas, and the production technology is quite backward. Farmers have a weak awareness of the prevention and treatment of diseases of Chinese medicinal materials, and blindly use pesticides, resulting in large-scale and frequent occurrence of diseases such as root rot and prickly-mouth disease of angelica. It has been increasing year by year and has become the main limiting factor for the production of angelica in authentic regions
At present, the research on Angelica sinensis at home and abroad is mainly focused on pharmacological efficacy, preparation extraction and chemical composition research. There is no systematic and in-depth research on the biological control of Angelica root rot. Therefore, the prevention and treatment of this disease is relatively blind, not only the control effect is not ideal , also caused serious environmental pollution problems, and also brought adverse effects on the quality of medicinal materials, which did not meet the requirements of the production management regulations for traditional Chinese medicinal materials

preparation example Construction

[0039] The preparation method of angelica special microbial fertilizer comprises the steps:

[0040] A. Stacking fermentation

[0041] Livestock manure and weathered coal are mixed and stacked into stacks, which are 1.8-3 meters wide, 1.2-1.5 meters high, and 2 meters long. After 20-30 days of fermentation, the material is air-dried to a moisture content of 10-15%, and crushed through an 80-mesh sieve.

[0042] B. Mixed fermentation

[0043] After uniformly mixing the materials in step A with Pseudomonas rapeseed fermentation liquid and Bacillus walliferium fermentation liquid, standing and fermenting for 7 to 10 days under the condition of 18°C ​​to 30°C, the special microbial fertilizer for Angelica sinensis is obtained.

[0044] The source of material used in the present invention:

[0045] Pseudomonas rapeseed and Bacillus walliferous strains: self-prepared according to the above method.

[0046] Livestock manure: purchased from sheep farms or cattle farms.

[0047] W...

Abstract

The invention belongs to the technical field of microbial fertilizers, and particularly relates to a special microbial fertilizer for angelica sinensis and a preparation method and application thereof. The microbial fertilizer comprises an organic fertilizer, weathered coal and an organic carrier, the organic fertilizer is animal manure, the organic carrier contains a rape pseudomonas fermentation broth and a bacillus muralis fermentation broth, and the microbial fertilizer is prepared from the following substances in parts by weight: 50-80 parts of animal manure, 20-60 parts of weathered coal, 5-15 parts of rape pseudomonas fermentation broth and 5-15 parts of bacillus muralis fermentation broth. The fertilizer is applied to Weiyuan, Minxian County, Longxi and other Chinese angelica genuine production areas in Gansu province, has remarkable soil-borne disease resistance and yield increasing effects, has the Chinese angelica root rot prevention and treatment effect of 45-48% and the yield increasing effect of 12-16%, and has great significance for green production of Chinese angelica.

Description

[0001] This application is a divisional application with an application date of July 25, 2016, an application number of 201610585180.3, and an invention title of "Angelica special microbial fertilizer and its preparation method". technical field [0002] The invention belongs to the technical field of microbial fertilizers, and in particular relates to the application of microbial fertilizers in resisting soil-borne diseases and / or increasing production of angelica. Background technique [0003] Over the past century, the high development of industrial production has caused air and soil pollution, and the extensive use of pesticides, chemical fertilizers, and hormones in the planting industry has caused increasing damage to the production environment. The use of bio-fertilizers with environmental protection and health care functions has become the only way for agricultural development. [0004] Angelica grows in western China and is usually planted in areas with higher altitu...
