Water-soluble fertilizer suitable for water and fertilizer integration

Abstract

The invention discloses a water-soluble fertilizer suitable for water and fertilizer integration. The water-soluble fertilizer is prepared from, by weight, 10-15 parts of monocalcium phosphate, 10-15parts of urea, 3-6 parts of monoammonium phosphate, 10-15 parts of monopotassium phosphate, 5-7 parts of potassium chloride, 1-2 parts of ferrous sulfate, 1-2 parts of zinc sulfate, 2-5 parts of ferrous gluconate, 5-8 parts of liquid complex enzyme preparation, 9-17 parts of accelerant and 100-200 parts of water. The water-soluble fertilizer suitable for water and fertilizer integration has complete nutrients and is solid, so that the water-soluble fertilizer is convenient to store and transport. The water-soluble fertilizer is good in dispersion in water, is rapidly and completely dissolved,and does not block pipelines, soil caking can be avoided while the fertilizer efficiency is guaranteed, the dispersion of soil is improved, thus, the soil texture and the farming performance are improved, the requirement of water and fertilizer integrated fertilization is met, use is convenient, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizer, and in particular relates to a water-soluble fertilizer suitable for the integration of water and fertilizer. 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 fertil...

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, calcium dihydrogen phosphate, 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; even if they are selected Ammonium dihydrogen phosphate, potassium nitrate, and potassium chloride with good solubility are used as raw materials for water-soluble fertilizers. 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
