Embodiment 1

[0045] The method for preparing seaweed foliage fertilizer with Ascophyllum nodosum as raw material comprises the following steps:

[0046] (1) Cleaning: select dry Ascophyllum nodosum fragments of a certain quality, add clear water 6 times its mass, stir at a speed of 20r / min, stir for 20min, repeat 2 times, drain the clear water and drain to obtain washed Ascophyllum nodosum pieces;

[0047] (2) Pulverization: pulverize the pieces of Ascophyllum nodosum obtained in (1) with a pulverizer, and obtain Ascophyllum nodosum powder after 80 mesh sieves;

[0048] (3) Enzymolysis: Add the Ascophyllum nodosum powder obtained in (2) into clear water 10 times its mass, stir at a speed of 40r / min and heat up to 50°C, adjust the pH to 5.5, and then add 3% of the Ascophyllum nodosum powder by weight. Enzyme preparation (the formula is papain: cellulase = 1:1), after 6 hours of enzymolysis, the temperature is raised to 60 degrees Celsius to terminate the enzymolysis;

Embodiment 2

[0055] The method for preparing seaweed foliage fertilizer with Ascophyllum nodosum as raw material comprises the following steps:

[0056](1) Cleaning: Select a certain quality of dry Ascophyllum nodosum fragments, add clear water 8 times its mass, stir at a speed of 30r / min, stir for 20min, repeat 2 times, let go of the clear water and drain to obtain washed Ascophyllum nodosum pieces;

[0057] (2) Pulverization: pulverize the pieces of Ascophyllum nodosum obtained in (1) with a pulverizer, and obtain Ascophyllum nodosum powder after 80 mesh sieves;

[0058] (3) Enzymolysis: Add the Ascophyllum nodosum powder obtained in (2) into clear water 12 times its mass, stir at a speed of 50r / min and heat up to 55°C, adjust the pH to 6, and then add 5% of the Ascophyllum nodosum powder by weight. Enzyme preparation (the formula is alginate lyase: cellulase = 1:1), after 7 hours of enzymolysis, the temperature is raised to 60 degrees Celsius to terminate the enzymolysis;

Abstract

The invention discloses a method for preparing a foliar fertilizer by taking ascophyllum nodosum as a raw material and the foliar fertilizer, and relates to the technical field of fertilizer preparation. The preparation method comprises the following steps: cleaning, crushing, enzymolysis, hot water extraction, concentration, ethanol precipitation, dissolution and compounding. In the enzymolysis process, a compound enzyme preparation is one or a combination of at least two of pectinase, papain, cellulase and seaweed gel lyase. The compound enzyme preparation can effectively destroy the cell structure of ascophyllum nodosum, decompose cell walls, expose active ingredients in cells, improve the extraction efficiency of effective substances, decompose macromolecular substances into substanceswhich are more beneficial to absorption and utilization by crops, and improve the fertilizer efficiency of the foliar fertilizer. According to the invention, the ascophyllum nodosum extracting solution is mixed with potassium dihydrogen phosphate and sugar alcohol chelated calcium to prepare the foliar fertilizer, and the foliar fertilizer is sprayed to crop leaves, can be quickly absorbed by crops, comprehensively supplements crop nutrition, improves crop growth conditions, and improves the stress resistance, yield and quality of crops.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to the preparation of a foliar fertilizer. Background technique [0002] The ocean is a huge treasure house of resources on the earth, and the development and utilization of ocean resources is a major issue in the 21st century. Seaweed is an important resource in the ocean. There are many types of seaweed, which can be divided into brown algae, green algae, and red algae. Its application range is very wide, covering food, medicine, chemical industry, health care, feed, fertilizer and other fields, and it is an important battlefield for the development of marine resources. [0003] Foliar fertilization is a supplement for plants to absorb nutrients to make up for the lack of root system absorption of nutrients. Foliar fertilization cannot replace soil fertilization. CN110818491A discloses a wheat foliar fertilizer and its preparation method. It first adds ice to yam ...
