Compounded organic fertilizer and preparation method therefor

Abstract

The invention discloses a compounded organic fertilizer and a preparation method therefor. The compounded organic fertilizer is prepared from the following raw materials in parts by weight: 30-50 parts of livestock and poultry manure, 10-15 parts of industrial and agricultural wastes, 3-5 parts of humic acid, 3-5 parts of activating powder, 4-6 parts of magnetized water straws, 2-4 parts of peat soil, 0.3-0.5 part of middling, 5-15 parts of soybean meal, 10-15 parts of rice hull powder, 1-5 parts of strain powder, 3-5 parts of urea, 4-6 parts of polyacrylamide, 0.1-5 parts of sodium glutamate, 0.1-5 parts of sodium alginate, 10-14 parts of monoammonium phosphate and 10-16 parts of potassium sulfate. According to the preparation method, the compounded organic fertilizer is prepared through firstly, preparing crushed materials from part of the raw materials, then, adding the remaining raw materials into the crushed materials, carrying out uniform stirring, then, carry out physical fermentation for 20 to 30 days, and then, carrying out drying and granulating. The compounded organic fertilizer is rich in organic substances and nutrients required for crop growth, is easy to decompose, is used for amending soil and can be used for improving the quality of crops and increasing the yield of the crops.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer products, in particular to a compound organic fertilizer and a preparation method thereof. Background technique [0002] Bio-organic fertilizer is organic solid waste, including organic waste, straw, manure, livestock, poultry manure, cake, agricultural by-products and solid waste produced by food processing, which is made by microbial fermentation, deodorization and complete decomposition organic fertilizer. Bio-organic fertilizers are rich in a variety of functional microorganisms and rich trace elements, which can improve soil structure, improve soil compaction, indirectly kill roundworm eggs and root nematodes, and play a role in nutrition, conditioning and health care for crop growth , so that the land absorbs organic matter to play a greater role. [0003] Bio-organic fertilizers have complete nutrients and can improve soil and improve soil compaction caused by the use of c...

Problems solved by technology

[0004] The preparation and use of traditional organic fertilizers is also very inconvenient. For example, organic waste such as livestock and poultry manure and garbage is a kind of dirty, rotten and smelly substances, which contain many pathogenic microorganisms, or are mixed with certain poisons, and are important sources of pollution. , it is especially worth noting that the excretion of heavy metals from livestock manure will seriously pollute the environment and affect human health
