Vinegar residue based modifier and preparation method thereof

Abstract

The invention discloses a vinegar residue based modifier and a preparation method thereof. The modifier is prepared from the following raw materials in parts by weight: 30-50 parts of vinegar residues, 20-40 parts of cow dung, 5-10 parts of nostoc sphaeroids kutz, 15-20 parts of bran, 5-10 parts of ferric sodium ethylenediaminetetraacetate, 10-20 parts of oat hulls, 10-15 parts of a crop straw powder, 1-5 parts of sawdust, 3-6 parts of red date branches, 3-6 parts of vinasse, 0.5-1.5 parts of urea, 1-3 parts of bacillus mucilaginosus, 2-6 parts of a bacillus subtilis inoculum, 1-5 parts of corynebacterium glutamicum, 3-5 parts of trichoderma virens, 1-3 parts of sulfonic acid bacteria, and 1-3 parts of brown-rot fungi. The vinegar residue based modifier can rapidly improve the pH value of soil, improves the soil organic matter content, has good soil improvement effect, and improves the quality of crops and vegetables.

Description

technical field [0001] The invention relates to the field of soil improvers, in particular to an acetate-based improver and a preparation method thereof. Background technique [0002] As an important industry in Shanxi Province, vinegar industry has developed rapidly in recent years. The increase in vinegar production has led to an increase in the output of solid waste vinegar residues. A large number of vinegar residues are piled up in the environment, lacking reasonable utilization methods, causing serious pollution and huge waste of resources. At present, the main ways of using vinegar grains include crop cultivation, feed production, food fermentation and biomass energy. [0003] In the past few decades, the use of chemical fertilizers has brought considerable economic benefits to agricultural production, but the long-term excessive application of chemical fertilizers has also led to a continuous decline in the physical and chemical properties and nutrient status of th...
