Method for producing composite microbial calcium-magnesium-sulfur-silicon fertilizer

Abstract

The invention discloses a method for producing a composite microbial calcium-magnesium-sulfur-silicon fertilizer. The method comprises the following steps: adding improved bacillus subtilis into sugar residues, uniformly mixing to obtain a mixture A, fermenting for 2 days, performing pile turning for the first time, and adding serpentine mineral powder, phosphogypsum, silicate bacteria, polymeric carbon enzymes, alkaline protease and improved rhizobium so as to obtain a mixture B; performing pile turning for the second time in 4 days, continuously fermenting, turning every 2-3 days after the temperature reaches 50-60 DEG C, thereby obtaining the product after fermentation completion. The raw materials respectively comprise the following components in parts by weight: 0.1-5 parts of improved bacillus subtilis, 12-35 parts of sugar residues, 30-55 parts of serpentine mineral powder, 40-75 parts of phosphogypsum, 0.1-4 parts of polymeric carbon enzymes, 0.1-2 parts of alkaline protease and 0.5-5 parts of improved rhizobium. The composite microbial calcium-magnesium-sulfur-silicon fertilizer prepared by the process disclosed by the invention contains lots of microbes, calcium magnesium sulfur silicon and the like and can achieve the effects of regulating the acid-base equilibrium of soil, improving the soil activity and increasing the yield of crops. Moreover, the fruit quality is improved, and the taste of the fruits is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for producing compound microbial calcium-magnesium-sulfur-silicon fertilizer. Background technique [0002] In recent decades, chemical fertilizers, chemical pesticides, chemical herbicides and other chemicals have been widely used in agricultural production. Variation in soil physical and chemical properties, soil compaction, reduced vitality, environmental pollution, reduced crop quality, excessive residues, and a decrease in the utilization rate of chemical fertilizers and pesticides year by year. The beneficial microorganisms with disease resistance have been greatly reduced. To change this situation, it is necessary to add organic matter and beneficial microorganisms to the soil, so microbial fertilizers came into being. In order to meet the needs of developing high-efficiency agriculture and pollution-free green agriculture, a compound microbial fertilizer was...

Problems solved by technology

However, the existing microbial fertilizers used by crops are mainly fertilizers containing nitrogen, phosphorus and potassium, which are called "macroelement fertilizers", while "medium and trace elements" contain calcium, magnesium, sulfur, zinc, iron, etc. Fertilizers are often overlooked

Moreover, traditional crop fertilizers have the problems of being unable to meet the needs of crops for nutrient elements, polluting the environment, having low utilization rates, and poor yield-increasing effects.
