Abstract

The invention discloses a fertilizer capable of improving alkaline soil and a preparation method thereof and relates to the field of fertilizers. The fertilizer comprises the following components in parts by mass: 40-60 parts of phosphorus ammonium nitrate, 5-20 parts of monoammonium phosphate, 5-20 parts of potassium nitrate, 20-30 parts of urea, 1-10 parts of potassium humate, 1-10 parts of calcium superphosphate, 1-10 parts of citric acid, 1-10 parts of potassium nitrate, 1-10 parts of ammonium sulfate, 0-10 parts of gamma-polyglutamic acid, 0-10 parts of hydrogen bentonite and 0-5 parts of trace elements. The fertilizer capable of improving the alkaline soil has the advantages that the alkalinity of the soil is reduced, the granular structure of the soil is improved, the soil compactness is reduced, and the slow-balancing capability of the soil is improved. Calcium superphosphate can supply phosphorus, calcium, sulfur and other elements to plants, has the effect of improving alkaline soil, can be used as a base fertilizer to be mixed with a nitrogen fertilizer for use, has a nitrogen fixation effect and reduces nitrogen loss.

Description

technical field [0001] The invention belongs to the field of chemical fertilizers, and in particular relates to a fertilizer for improving alkaline soil and a preparation method thereof. Background technique [0002] In alkaline soil, due to high salt content, low organic matter content, poor soil physical and chemical properties, poor buffer performance, low water retention and fertility, there are many anions and cations harmful to crop growth, which is not conducive to the growth and development of crops, and the land productivity and carrying capacity are low . The higher the degree of alkalization of the soil, the worse the physical and chemical properties. When it is wet, it is easy to swell, muddy, and disperse, and when it is dry, it will shrink, hard, and harden. The high dispersion of sodium ions is the main cause of these hazards. It can substitute with other salts contained in the soil, resulting in the formation of sodium carbonate, which has high alkalinity, a...
