Seaweed oligosaccharide micro-ecology drip irrigation fertilizer and preparation method thereof

Abstract

The present invention belongs to the technical field of seaweed fertilizers, and particularly relates to a seaweed oligosaccharide micro-ecology drip irrigation fertilizer, which comprises, by weight, 10-60% of a seaweed oligosaccharide solution, 10-50% of a molasses solution, 20-40% of a composite microorganism bacterial solution, and 10-40% of large, medium and trace elements, wherein crushed seaweed and water are mixed, a biological lyase is added to carry out enzymolysis so as to obtain a seaweed enzymolysis liquid, and extraction and pressure filtration are performed under an alkaline condition so as to obtain the seaweed oligosaccharide solution. The invention further provides a preparation method of the seaweed oligosaccharide micro-ecology drip irrigation fertilizer. According to the present invention, the effective component in the seaweed is substantially retained, the utilization rate of crops on the nutrients can be substantially improved, the preparation period is substantially shortened, the necessary organic matter and the trace elements can be supplemented, the composite microorganism bacterial solution is added, functions of disease resistance, stress tolerance, phosphorus dissolving, potassium dissolving, and soil physical structure increasing are provided, and various types of soil-borne diseases can be effectively prevented and controlled.

Description

technical field [0001] The invention belongs to the technical field of seaweed fertilizer, and in particular relates to a seaweed oligosaccharide micro-ecological drip irrigation fertilizer and a preparation method thereof. Background technique [0002] Seaweed fertilizer is a natural organic fertilizer, and its fertilizer efficiency depends on the nutrients contained in the seaweed fertilizer. The seaweed used as fertilizer is generally large economical seaweed. The development of seaweed fertilizer has gone through three stages: rotting seaweed → seaweed ash (powder) → seaweed extract. The core substance in seaweed fertilizer is pure natural seaweed extract. The main raw material is selected from natural seaweed. After special biochemical treatment, the essence of seaweed is extracted, and the natural active components are retained. It contains a large amount of non-nitrogenous organic matter, which land plants cannot More than 40 kinds of mineral elements such as potassi...

AI Technical Summary

Problems solved by technology

However, at present, the seaweed fertilizer added with biological bacteria, the biologically active substances in the seaweed fertilizer are seriously damaged, and the added strain is single, which can improve the fertilizer utilization rate, improve the soil structure, improve the comprehensive fertility of the soil, promote the formation of beneficial microbial groups, and enhance Unsatisfactory effect on crop disease resistance

[0007] The production method of seaweed fertilizer has a great influence on the content of biologically active substances and nutrients in the product. At present, the production of seaweed fertilizer mainly adopts chemical hydrolysis method, physical extraction method, enzymatic method, biological fermentation method, etc. The environment will destroy the activity of the endogenous substances of seaweed. The physical extraction method uses high temperature and low pressure cooling technology to achieve the purpose of breaking the cell wall o
