Problems solved by technology

A common feature in the production process of high-tower compound fertilizers is that about 10% of the particle size does not meet the product standard, and it needs to be returned to melt and re-granulate, which wastes energy and increases fertilizer production costs.

Abstract

The invention relates to water soluble fertilizer and a preparation method thereof. The water soluble fertilizer consists of an ingredient A and an ingredient B by a weight ratio of 1: (0.5-1.2). The ingredient A is returning charge which does not meet the grain size standard of screened solid particles in production of tower composite fertilizer, and consists of large particles with grain size greater than 4.75mm and fine powder with grain size less than 1mm. The ingredient B consists of nitrogenous fertilizer, phosphatic fertilizer and potash fertilizer by a weight ratio of nitrogen to phosphorus pentoxide to potassium oxide of 1: (0.9-2.5): (0-3.0) or conventional microelement fertilizer is further added to the ingredient B. The invention further provides the preparation method of the water soluble fertilizer. The production costs of the tower composite fertilizer and the water soluble fertilizer are saved, the nutrient is agilely proportioned, the water soluble fertilizer with different proportions of nitrogen, phosphorus and potassium can be simply and conveniently produced, and the fertilizer is strong in selectivity to different soils and crops and high in utilization ratio of nutrients.

Description

technical field [0001] The invention relates to a high-tower compound fertilizer co-production water-soluble fertilizer and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Water-soluble fertilizer is a new type of fertilizer developed in my country in recent years. It has good water solubility and less impurities, and is suitable for fine irrigation and fertilization such as drip irrigation and sprinkler irrigation. With the development of domestic modern agriculture and water-saving agriculture, the demand for water-soluble fertilizers is increasing. New water-soluble fertilizers are also constantly appearing, such as CN101024590 (200710017334.X) which relates to a preparation method of a water-soluble fertilizer containing humic acid, which is a stable and nutritious humic acid fertilizer; CN101570456 (200910130413.0) discloses a A water-soluble fertilizer and a production method thereof are a water-so...
