Description

Technical Field

[0002] Fertilizers refer to substances that provide one or more essential nutrient elements for plants and improve soil properties and soil fertility levels, and are one of the material bases for agricultural production. They mainly include ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. In the process of modern agricultural production, the use of fertilizers is one of the key factors to improve crop yield and quality. Generally, they are divided into organic fertilizers, inorganic fertilizers, and biological fertilizers.
