Problems solved by technology

[0003] The object of the present invention is: aiming at the problems that existing water-soluble fertilizers have few types of nutrients, low nutrient content, and too fast release of nutrients so that crops cannot absorb them, resulting in low utilization rate of fertilizer nutrients. The present invention provides a new type of solid water-soluble fertilizer and its preparation method

Abstract

The invention discloses novel solid water-soluble fertilizer and a preparation method thereof. The water-soluble fertilizer comprises, by weight percentage, 27-45% of water-soluble ammonium polyphosphate, 30-50% of agricultural compound amino acid raw powder, 10-30% of potassium humate, 3-5% of anhydrous potassium carbonate, 1-5% of trace element and 0.01-0.05% of surfactant. The novel solid water-soluble fertilizer has the advantages that the fertilizer contains inorganic nutrition and organic nutrition and is comprehensive in nutrition types and high in nutrition content, the situation thata large amount of nutrition is released after the fertilizer is applied and plants cannot absorb all the nutrition is avoided by the aid of the sustained-release and lasting-effect water-soluble ammonium polyphosphate, fertilizer nutrition utilization rate is increased, the used raw materials are cheap and easy to obtain, and production cost can be further lowered.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a novel solid water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizer (Water Soluble Fertilizer, referred to as WSF), is a kind of multi-component fertilizer that can be completely dissolved in water to meet the needs of modern agricultural production. It can be quickly dissolved in water and is more easily absorbed by crops. The efficiency is relatively high, especially it can be applied to facility agriculture such as spraying, dripping, and irrigation to realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor. At present, most of the water-soluble fertilizers in the fertilizer industry are single inorganic water-soluble fertilizers or single organic water-soluble fertilizers. There are very few inorganic and organic compound or compound water-soluble fertiliz...
