Abstract

The invention provides a compound fertilizer and a preparation method thereof and relates to the technical field of fertilizers. The compound fertilizer comprises the following raw materials in parts by weight: 20-25 parts of decomposed coal, 15-18 parts of peat soil, 2-8 parts of ground phosphate rock, 6-10 parts of potassium mineral, 5-13 parts of potassium fulvic acid, 22-30 parts of a rice hull powder, 15-25 parts of a sweet potato powder, 5-11 parts of urea, 5-8 parts of polyacrylamide, 5-11 parts of turf, 18-32 parts of rapeseed meals, 5-15 parts of straws, 24-32 parts of poultry manure, 15-19 parts of attapulgite, 11-15 parts of manioc waste, 7-11 parts of distillers' grains, 3-7 parts of a yeast species powder and 3-9 parts of a nitrogen-fixing strain powder. The compound fertilizer prepared by the invention has the advantages of low cost, rich nutrient elements, diversified sources types of raw materials and excellent soil improvement effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compound fertilizer and a preparation method thereof. Background technique [0002] Due to the long-term application of a large amount of inorganic fertilizers, the lack of trace elements in the soil, especially in areas with relatively good economic conditions, the application of a large amount of high-concentration chemical fertilizers, compound fertilizers, and potassium fertilizers has caused serious soil enrichment of nutrients and serious loss of trace elements. The overall quality of the soil is declining, and organic fertilizer resources must be utilized in order to fertilize the soil. Organic fertilizers are rich in various trace elements, which can well make up for the shortage of chemical fertilizers. The basic path of scientific fertilization is to use organic fertilizers and inorganic fertilizers together to improve the utilization rate of chemical...
