Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, in particular to a full-valent compound fertilizer premix and a preparation method thereof. Background Art

[0002] Fertilizer refers to a substance that can provide nutrients needed for crop growth and development, improve soil properties, and increase crop yield and quality. It is one of the material bases of agricultural production and is generally divided into organic fertilizers, inorganic fertilizers, and biological fertilizers.

[0003] The nutrients required by plants include macroelements, secondary elements, trace elements, etc. All nutrients are indispensable for plant growth. However, traditional compound fertilizers only contain nitrogen, phosphorus and potassium nutrients. This type of fertilizer is not comprehensive in nutrition, has low fertilizer efficiency, and is not widely applicable. It cannot meet the nutritional needs of plants and improve the quality and yield of crops. Moreover, current fertilizers are generally acidic. After applying these acidic fertilizers, the soil will become severely acidified. Acidified soil will aggravate soil compaction, causing poor development of plant roots, weakened plant growth, reduced disease resistance, and susceptibility to virus infection.
