Problems solved by technology

However, the amount of cellulase, papain and pectinase used in this patent is not much different. Since the price of protease is much more expensive than other enzymes, if the same amount of protease is used, the processing cost will increase, resulting in unnecessary resources. waste
In addition, this patent also has the problem of insufficient enzymatic hydrolysis

Embodiment 1

[0077] A compound microbial enzyme is composed of 100% cellulase, wherein the selected cellulase has an enzyme activity of 200,000 μ / g. Take 100ml of kelp slurry, add the compound microbial enzyme at a ratio of 0.4% to the kelp slurry to form a mixed solution, keep it warm for 18 hours, and measure the content of alginic acid in the supernatant to be 17.25g / L.

Embodiment 2

[0079] A compound microbial enzyme, which is formed by mixing 60% cellulase and 40% pectinase by mass percentage, wherein the selected cellulase has an enzyme activity of 120,000 μ / g, and the enzyme activity of pectinase The activity is 12,000 μ / g. Take 100ml of kelp slurry, add the compound microbial enzyme in a ratio of 0.4% to the kelp slurry to form a mixed solution, keep it warm for 18 hours, and measure the content of alginic acid in the supernatant to be 19.56g / L

Embodiment 3

[0081] A compound microbial enzyme, which is mixed with 60% cellulase, 35% pectinase and 5% protease by mass percentage, wherein the selected cellulase has an enzyme activity of 120,000 μ / g, The enzyme activity of pectinase is 10,500 μ / g, and that of protease is 25,000 μ / g. Take 100ml of kelp slurry, add the compound microbial enzyme at a ratio of 0.4% to the kelp slurry to form a mixed solution, keep it warm for 18 hours, and measure the content of alginic acid in the supernatant to be 21.32g / L.

Abstract

The invention relates to a preparation method of a plant nutrient solution. The preparation method includes following steps: mixing fresh kelp pulp with a composite microorganism enzyme to obtain a mixture; and performing enzymolysis to the mixture of the fresh kelp pulp and the composite microorganism enzyme in an enzymolysis pot for obtaining the plant nutrient solution, wherein the composite microorganism enzyme includes more than one of cellulase, pectinase, protease and amylase and a mass percentage of the cellulase and the pectinase is far more than that of the protease and the amylase. The preparation method has a simple enzymolysis technology, is mild in reaction conditions, is low in cost, is free of any other chemical components during the reaction processes and enables more active ingredients in fresh kelp to be retained.

Description

technical field [0001] The invention relates to the technical fields of biotechnology and plant nutrition, in particular to a method for preparing a plant nutrient solution, in particular to a plant nutrient solution prepared from seaweed. Background technique [0002] In my country, with the continuous improvement of people's living standards and the basic settlement of food and clothing problems, high-yield and high-quality agricultural products and hygienic and healthy food have become urgent needs in the current society and agricultural production. For this reason, the Ministry of Agriculture held a green food working conference in 1990 to promote the development and production of pollution-free healthy food. The document of the State Council on the development of green food pointed out: "The development of green food has a profound impact on protecting the ecological environment, improving the quality of agricultural products, promoting the development of the food indus...
