Abstract

The invention provides a sulfur-containing composite microbial fertilizer. The sulfur-containing composite microbial fertilizer comprises following ingredients, by mass, 3 to 30% of phosphogypsum, 1 to 10% of a composite microbial agent, no more than 35% of water, and no less than 6% of a total nutrient (N+P2O5+K2O). The composite microbial agent is prepared by mixing bacillus megaterium and thiobacillus thiooxidans microbial agents which are processed by fermentation and adsorption. The invention also provides a production method of the sulfur-containing composite microbial fertilizer. The production method comprises steps of treatment of phosphogypsum, preparation of the composite microbial agent, and preparation of the sulfur-containing composite microbial fertilizer. According to the production method, industrial production waste phosphogypsum is added as a fertilizer, so that the production method is beneficial for environmental protection, and is capable of solving a problem of waste accumulation for manufacturing enterprises, realizing reclamation of wastes, and meeting with the demands of sustainable development.

Description

technical field [0001] The invention relates to the field of compound microbial fertilizers, in particular to a sulfur-containing compound microbial fertilizer and a production method thereof. Background technique [0002] Sulfur (S) is the fourth major plant nutrient element after nitrogen (N), phosphorus (P), and potassium (K), and its content in plants is about 0.1% to 0.5%. Sulfur is a component of sulfur-containing amino acids, proteins, and many enzymes, and is formed and present in glycoside oils of onions, garlic, and cruciferous plants. Therefore, Brassicaceae and Liliaceae crops such as rapeseed need more sulfur. However, the importance of sulfur as a fertilizer nutrient and agricultural requirement is not well understood. From 1997 to 2005, TSI cooperated with 15 Chinese scientific research institutes to carry out balanced sulfur application projects. Its main purpose is to understand soil sulfur deficiency and evaluate the effect of balanced sulfur fertilizati...
