Problems solved by technology

However, the existing high-tower compound fertilizers (such as the above-mentioned patent documents) have no special restrictions on sulfate ions, and direct application to the soil can easily cause soil compaction, especially in the case of large amounts of fertilization in orchards and facility vegetable fields.

Abstract

The invention relates to a fertilizer for preventing soil hardening and a preparation method thereof. The fertilizer for preventing soil hardening is prepared by mixing an ingredient A and an ingredient B according to the mass ratio of 20-50:50-80 and granulating. The ingredient A is a returned material part which doesn't accord with particle size standard and is obtained after screening of fertilizer particles generated from tower granulation in the tower composite fertilizer production. The ingredient B is composed of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and humic acid according to the mass ratio of 5-15:20-40:20-30:20-40. The invention also provides the preparation method of the fertilizer for preventing soil hardening. According to the invention, the returned material which contains powders with the particle size of being less than 1 millimeter and particles with the particle size of being greater than 4.75 millimeters and are generated from the tower composite fertilizer production is used as an ingredient, and then nitrogen, phosphor and potassium fertilizers exclusive of sulfate ions and humic acid are cooperatively added according to soil nutrients and crop required fertilizers. Thus, production cost is saved, soil hardening phenomenon can be reduced, and crop root growth is promoted.

Description

technical field [0001] The invention relates to a high-tower compound fertilizer co-production fertilizer for preventing soil compaction and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] At present, the chemical fertilizers used in my country's agricultural production contain a large amount of sulfate ions, such as ammonium sulfate, potassium sulfate, magnesium sulfate, etc., especially in the fertilization of fruit trees, vegetables and other crops, due to the long-term application of potassium sulfate in large quantities, the sulfate ions Ions accumulate in the soil. Sulfate ions are easy to combine with calcium ions in the soil to form calcium sulfate precipitation, which not only reduces the availability of calcium in the soil, but more importantly, the long-term accumulation of calcium sulfate makes the soil harden, which is not conducive to the growth of crop roots.
