Abstract

The invention discloses a composite amino-acid-containing water-soluble fertilizer which comprises the following components: amino acid materials, major elements such as N, P and K, secondary elements such as Mg and Ca, minor elements such as Fe, Mn, Zn, B, Mo and Cu, assistants, a pH value regulator and a water solution. The preparation method of the fertilizer comprises the following step: chelating the composite amino acids with six metal elements (Mg, Ca, Fe, Mn, Zn and Cu) at normal temperature (15-(-35) DEG C) according to a specific sequence, thus obtaining the water-soluble fertilizer. According to the composite amino-acid-containing water-soluble fertilizer, 18 amino acids and 11 nutrient elements are enriched, the six metal elements are wholly chelated, all the components are stably dissolved, and no antagonism and precipitation problems exist.

Description

Technical field:

[0001] The invention belongs to water-soluble fertilizers produced in agriculture, and in particular relates to a compound amino acid-containing water-soluble fertilizer and a preparation method thereof. technical background:

[0002] Fertilizer is a direct or indirect supplier of nutrients needed for crop growth, and has the function of improving soil properties and improving crop yield and quality. However, for a long time, large or excessive application of chemical fertilizers has not only caused problems such as low soil fertility utilization rate, nutrient imbalance, soil compaction, and soil microbial community imbalance, but also caused a series of environmental problems such as environmental pollution and nutrient enrichment. The losses caused by chemical fertilizers in terms of environmental pollution are as high as 100 billion yuan.

[0003] Water-soluble fertilizer is a kind of fertilizer that can be completely dissolved in water. It can be quick...
