Organic fertilizer and preparation method thereof

Abstract

The invention relates to an organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by weight: 10% to 15% of peanut oil sludge, 10% to 15% of sesame oil sludge, 20% to 30% of mushroom residue, 20% to 30% of activated carbon, and 20% to 30% of argil. A preparation method for the organic fertilizer comprises the following steps of primarily crushing 14% of peanut oil sludge, 13% of sesame oil sludge, 27% of mushroom residue, 26% of activated carbon, and 20% of argil according to a ratio in parts by weight, and uniformly stirring, so as to obtain an initial raw material; transferring the initial raw material into a fermenting tank to ferment, so as to obtain a fermented material; aging the fermented material, so as to obtain a primary fertilizer; dewatering the primary fertilizer, drying, and screening, so as to obtain the finished organic fertilizer. The organic fertilizer has the characteristics that the production cycle is short, and the contentof nutritional components is high; the pollution to environment is avoided, the soil granule structure can be quickly formed, and the water and soil are conserved to promote the growth and development of plants.

Description

technical field [0001] The invention relates to the field of fertilizer manufacturing, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers still occupy a dominant position in agricultural fertilizers because of the characteristics of easy storage, convenient application and quick effect. However, with the long-term use of chemical fertilizers, the soil is compacted year by year, and the soil quality is declining year by year. At the same time, chemical fertilizers and pesticides are used in agricultural production. It also brings potential threats to water quality, soil and the environment. At present, the pollution problem of agricultural products is becoming more and more serious, the toxic residues of agricultural products are getting higher and higher, the quality of agricultural products is gradually declining, and the market competitiveness is also weakened. Anxiety, so the demand for organic ferti...

[0002] Chemical fertilizers still occupy a dominant position in agricultural fertilizers because of their easy storage, convenient application, and quick results. However, with the long-term use of chemical fertilizers, the soil is compacted year by year, and the soil quality is declining year by year. At the same time, chemical fertilizers and pesticides are used in large quantities in the agricultural production process It also poses a potential threat to water quality, soil and the environment. At present, the pollution of agricultural products is becoming more and more serious, the toxic residues of agricultural products are getting higher and higher, the quality of agricultural products is gradually declining, and the market competitiveness is also weakening. concerns, so the demand for organic fertilizers continues to increase
