Abstract

The invention relates to the field of agricultural fertilizer, and in particular to a composite fertilizer for wheat plantation. Aiming at the fertilizer demand characteristics of wheat, the status quo of the wheat plantation fertilizer in our country, and harm of single fertilizer administration, the invention provides a composite fertilizer for wheat plantation. The composite fertilizer enhances soil fertility, improves soil structure, reduces pesticide residues, and overcomes the harm on soil and crop of single fertilization. The technical scheme is as below: a composite fertilizer for wheat plantation is prepared from the following components by weight: 30-40 parts of lignite, 30-40 parts of urea, 20-25 parts of monoammonium phosphate, 10-15 parts of potassium chloride and 3-5 parts of Bacillus subtilis. The preparation method is by mixing the above ingredients, crushing, mixing, granulating, drying, screening and packing. Compared with the simple substance fertilizer, the provided by the invention has complete fertilizer nutrients, small amount of sub-component and good physical and chemical properties, and is conducive to the realization of scientific fertilization.
