Problems solved by technology

[0006] Alginic acid fertilizer has been widely used as a kind of agricultural fertilizer. For example, the Chinese patent application document with publication number CN101913949A discloses a low molecular weight oligomeric alginic acid fertilizer. Intermediate elements react to form precipitates, and this patent does not add intermediate elements
The publication numbers are CN1569755A, CN1229778A, CN101485343A and other Chinese patent application documents related to the extraction of seaweed, but these extracted seaweeds are alginic acid with large molecular weight, which must be degraded to a certain extent before the plants can be used.
Publication numbers CN1229778A, CN1944353A, CN102173907A and other Chinese patent application documents all involve seaweed and amino acids, but because the seaweed and amino acids are extracted from algae and a large number of other ingredients are added, the concentrations of alginic acid and amino acids are relatively low
At present, there is no report on the patent of liquid fertilizers containing high concentrations of alginic acid and amino acids at the same time

Abstract

The invention discloses seaweed amino acid composite liquid manure and a preparation method and application thereof, and belongs to the field of manure industry. Preparation of the seaweed amino acid composite liquid manure comprises the following steps: (1) alginate is degraded: under the condition that catalysts and hydrogen peroxide exist, the alginate is degraded to alginic acid solutions; (2) amino acid is chelated for the first time: animal fur is added to mixed acid composed of hydrochloric acid, sulfuric acid and phosphoric acid for acidolysis, and chelation of the animal fur and neutralizer under the condition that a chelating agent exists is carried out to obtain amino acid solutions; and (3) secondary chelating is carried out: the alginic acid solutions and the amino acid solutions are mixed to react, and then humic acid salt, major elements and microelements are added for the secondary chelating, and finally manure synergist is added to obtain the seaweed amino acid composite liquid manure. The prepared seaweed amino acid composite liquid manure is easily absorbed by crops and strong in physiological activity, yield of the crops is increased, quality of the crops is improved, and damage of heavy metals to human is reduced.

Description

technical field [0001] The invention belongs to the field of fertilizer industry and relates to a seaweed amino acid compound liquid fertilizer and its preparation method and application. Background technique [0002] The total amount of chemical fertilizers used in the country increased from 47.66 million tons in 2005 to 55.62 million tons in 2010. The excessive application of these fertilizers not only caused serious environmental pollution, but also caused excessive nitrite content in agricultural products and drinking water, seriously threatening national safety. [0003] Traditional chemical fertilizers have single fertilizer efficiency and serious pollution. Long-term application of chemical fertilizers has damaged the farmland ecological environment, soil physical and chemical properties, and soil beneficial bacteria to varying degrees, which has a great impact on the quality of crops. In particular, excessive application of simple chemical fertilizers such as nitrog...
