Water soluble fertilizer and preparation method thereof

Abstract

The invention discloses a water soluble fertilizer, which is composed of the following raw materials in parts by weight: 10 to 15 parts of calcium superphosphate, 10 to 15 parts of urea, 3 to 6 parts of ammonium sulfate, 10 to 15 parts of potassium dihydrogen phosphate, 5 to 7 parts of potassium sulfate, 1 to 2 parts of ferrous sulfate, 1 to 2 parts of zinc sulfate, 2 to 5 parts of ferrous gluconate, 5 to 8 parts of liquid composite enzyme preparation, 9 to 17 parts of promoter, and 100 to 200 parts of water. The invention also discloses a preparation method of the water soluble fertilizer. The water soluble fertilizer has the advantages that the nutrients are comprehensive; the water soluble fertilizer is in a solid state, is convenient to store and transport, can be well dispersed in water, is capable of being dissolved rapidly and completely, does not obstruct the pipeline, can guarantee the fertilizing effect, and at the same time, can prevent soil hardening and increase the dispersity of soil; so the quality and cultivating property of soil are both improved, the water and the fertilizer can be applied to the fields at the same time, the water soluble fertilizer is user-friendly, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer soluble in water. It is a new type of fertilizer that has emerged in recent years. It can be quickly dissolved in water, more easily absorbed by crops, and has a relatively high absorption and utilization rate, realizing the integration of water and fertilizer. , to achieve the effect of saving water, fertilizer and labor. my country is a large agricultural country with a large population and a serious shortage of water resources. The per capita share is equivalent to 1 / 4 of the world's per capita share. The share used for agricultural production is also declining, which has formed a very serious problem. In terms of agriculture , The vigorous development of water-saving fertilizers cannot wait. ...

AI Technical Summary

Problems solved by technology

Because most of the traditional compound fertilizer raw materials do not have the characteristics of full water solubility, such as phosphate rock powder, superphosphate, calcium magnesium phosphate fertilizer and other fertilizers commonly used in agriculture, due to their limited solubility, they cannot be used as raw materials for water-soluble fertilizers; Ammonium dihydrogen phosphate, potassium nitrate, potassium sulfate, etc. are better used as water-soluble fertilizer raw materials. Due to the limited purity, it is difficult to meet the requirements of complete water solubility.

The existing traditional fertilizer raw materials need to be continuously purified to become water-soluble fertilizers, which not only results in increased energy consumption and cost, but also has a single nutrient element

[0004] Furthermore, water-soluble fertilizers are usually a complex of various nutrients. Due to the differences in the properties of different fertilizer raw materials during the compounding process, the water-soluble fertilizers composed of various raw materials will change in their own performance and environment during storage and use, resulting in water-soluble fertilizers. Poor performance, even react with each other to form precipitates when water-soluble, which is a serious defect for the use of water-soluble fertilizers, and cannot fully meet the requirements of integrated water-fertilizer fertilization, not only will cause blockage of pipelines, but also serious loss of fertilizer efficiency
