Abstract

The invention discloses biological organic fertilizer. Raw materials of the fertilizer includes modified biological carbon, sugarcane leaves, crop straw, corncobs, excrement of livestock and poultry,a fermentation bacterial inoculant, a functional microbial strain, ammonium chloride, potassium nitrate, calcium magnesium phosphate, monopotassium phosphate and compound trace elements. The inventionalso discloses a preparation method of the biological organic fertilizer. Under interaction of each added raw material, nutrients are supplied to meet the growth demands of crops; meanwhile, the utilization rate of fertilizer nutrients can also be increased, the soil structure can be improved, and healthy growth of crops is facilitated.

Description

Technical field [0001] The invention relates to the technical field of agricultural production, in particular to a biological organic fertilizer and a preparation method thereof. Background technique [0002] Although traditional inorganic chemical fertilizers have high nutrient content and rapid fertilizer efficiency, the fertilizer effect is strong but not long. The effect of improving the soil is not very large, and even has the side effect of destroying the nature of the soil. The large-scale use of inorganic fertilizers in agricultural production will bring about agricultural products such as Various problems such as deterioration of quality, soil compaction, and water pollution. With the improvement of people's living standards, the residents' demand for safe, hygienic and pollution-free organic and green food is increasing. The majority of farmers urgently need to apply organic fertilizer to improve the market competitiveness of agricultural products. Summary of the inven...
