Abstract

The invention discloses a preparation method of a seaweed compound fertilizer. The preparation method comprises the following steps: soaking dry kelp and dry ascophyllum nodosum in clear water, carrying out washing and drying, conducting grinding into powder, and performing uniform stirring to obtain seaweed powder; adding water into the seaweed powder, fully dissolving the seaweed powder, and conducting uniform stirring to obtain seaweed slurry; adding an organic solvent into the seaweed slurry, and performing uniform mixing; adding the seaweed slurry into a fermentation tank, adding a compound enzyme preparation, and carrying out fermenting to obtain a seaweed extract; and adding a chemical fertilizer into the seaweed extract, carrying out heating, stirring and complete dissolving, performing filtering to remove impurities, and carrying out drying and granulating to obtain the seaweed compound fertilizer. The preparation method provided by the invention can improve the fertilizer utilization rate of traditional chemical fertilizers, reduce fertilizer waste, lower environmental pollution, improve crop stress resistance, regulate crop growth, and improve crop quality and yield.

Description

technical field [0001] The invention belongs to the field of seaweed fertilizer, and in particular relates to a seaweed compound fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and it is also a populous country. The area of ​​cultivated land per capita is small, and the area of ​​high-quality cultivated land is even less. Agricultural production relies too much on chemical fertilizers to increase production. As a result, the total amount of fertilizers applied every year is astonishing, and the amount of chemical fertilizers used per unit area ranks first in the world. Moreover, the planting structure is single, the proportion of field crops is large, the fertilization is unbalanced all the year round, and large chemical fertilizers are re-applied. At the same time, my country's current traditional chemical fertilizers have single fertilizer efficiency and low utilization rate. Year-round use will destroy ...
