Abstract

The invention provides a cadmium-reducing base material for ligusticum wallichii planting, a fertilizer and application of the base material. The base material comprises an organic fertilizer obtained through kitchen waste treatment, a calcium magnesium phosphate fertilizer and biological bacteria, the organic fertilizer obtained through kitchen waste treatment contains organic matter and humic acid, and the biological bacteria comprise bacillus laterosporus and bacillus subtilis. The organic fertilizer and the calcium magnesium phosphate fertilizer are used for improving the physical and chemical properties of soil and reducing the effectiveness of soil cadmium so as to reduce the cadmium adsorption of ligusticum wallichii; and two biological bacteria, namely bacillus laterosporus and bacillus subtilis, are combined and can be used in two ways, root promotion and cadmium reduction are realized, and synergistic interaction is realized. The fertilizer comprises the following components in parts by weight: 10-22 parts of zinc sulfate, 18-22 parts of sodium silicate and 400-650 parts of a base material for cadmium reduction in ligusticum wallichii planting. Zinc sulfate and cadmium in the fertilizer have antagonism, so that the cadmium adsorption of ligusticum wallichii can be reduced. Sodium silicate and cadmium form insoluble cadmium silicate, so that the effectiveness of cadmium can be reduced, and meanwhile, the cell wall of ligusticum wallichii is strengthened to improve the resistance to various diseases.

Description

technical field

[0001] The invention relates to the field of soil fertilizers, in particular to a cadmium-reducing base material for planting Rhizoma Chuanxiong, fertilizer and application thereof. Background technique

[0002] Ligusticum Chuanxiong is a commonly used Chinese herbal medicine. It is often used to promote blood circulation, expel wind and relieve pain. It is pungent, warm, fragrant and dry. It is a cultivated plant, mainly produced in Sichuan (Pengzhou), and grows in mild climates in Yunnan, Guizhou, Guangxi and other places. Due to the high content of cadmium in the soil environment in some parts of Southwest China, and the fact that Rhizoma Chuanxiong plants have a certain enrichment effect on cadmium elements, the double impact has led to the current excessive cadmium content in rhizomes of Rhizoma Chuanxiong, which has seriously affected its circulation in the market, and even affected the The development of my country's traditional Chinese medicine indust...
