Abstract

The invention discloses a seaweed calcium-magnesium fertilizer, and belongs to the technical field of water-soluble fertilizers. The high-concentration calcium-magnesium water-soluble fertilizer is prepared through chelation reaction of calcium ions, magnesium ions, fish protein polypeptide, small peptide and amino acid, a certain amount of seaweed zymolyte is added, the modification effect of functional active substances such as algal polysaccharides on the calcium-magnesium chelate is fully utilized, the stability of the calcium-magnesium fertilizer is remarkably improved, the problems of precipitation and layering caused by direct mixing are avoided, the product is good in water solubility and can be easily and thoroughly absorbed by plants, and the product utilization rate is increased; and meanwhile, through synchronous chelation reaction of calcium ions and magnesium ions, the calcium ions and the magnesium ions act on plants at the same time, the synergistic effect of the calcium ions, the magnesium ions, fish protein polypeptide and seaweed zymolyte is brought into full play, acid soil can be remarkably improved, the calcium deficiency symptom of crops is prevented, the yield of commercial crops is increased, and the quality is improved. The fertilizer can be used for foliar spraying, can also be used along with water flushing, and is simple, convenient, high in absorption and utilization rate and wide in market prospect.

Description

technical field [0001] The invention relates to a seaweed calcium-magnesium fertilizer and a preparation method thereof, in particular to a seaweed calcium-magnesium fertilizer which significantly improves acidic soil, prevents the symptoms of calcium deficiency in crops, increases the yield of economic crops, and improves the quality of the seaweed calcium-magnesium fertilizer and a preparation method thereof, which belongs to the technology of water-soluble fertilizers field. Background technique [0002] Trace element fertilizers play a very important role in plant production, and are an important part of water-soluble fertilizers, and are widely used. Calcium and magnesium ions are essential elements for plant growth, among which calcium is a component and activator of some enzymes in plants, which has a certain impact on the metabolism of nitrogen and carbohydrates; calcium has the effect of eliminating certain organic acids in plants. Reduce the toxicity of organic ac...
