Abstract

The invention relates to a synergist for a polyaspartic acid fertilizer. The synergist is characterized by comprising, by mass percent, 10-35 parts of synergistic components, 15-50 parts of inorganic nutrient components and 2-8 parts of auxiliary components. A preparation method of the synergist for the polyaspartic acid fertilizer comprises: respectively weighing the synergistic components and the inorganic nutrient components according to the mass percent proportion, uniformly stirring and mixing the weighted synergistic components and the inorganic nutrient components, and then irradiating; adding the auxiliary components into the irradiated products, mixing, spraying, granulating and drying to obtain finish product. The synergist for the polyaspartic acid fertilizer is relatively good in water retention performance, and can promote crop absorption and thus improve quality and output of the crops. Meanwhile, the preparation method provided by the invention is simple, scientific and reasonable, and realizes goals of energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to a polyaspartic acid fertilizer synergist prepared from polyaspartic acid as a raw material and a preparation method thereof. Background technique [0002] In recent years, many systematic studies have been carried out on the loss pathways of nitrogen, phosphorus and potassium in the soil-crop system under field conditions. These studies provide a basis for the rational application of chemical fertilizers in agricultural production, the improvement of chemical fertilizer utilization, the reduction of chemical fertilizer losses, and the protection of human beings. The living environment and so on are of great significance. For example, various synergists can be used to increase the utilization rate of fertilizers, increase food production and reduce environmental pollution. However, there are still deficiencies in the existing preparations and technical me...
