Abstract

The invention relates to a hydrogel plant nutrient composition and a preparation method thereof. The hydrogel plant nutrient composition is composed of hydrogel containing macroelement nutrient substances and hydrogel containing medium and trace nutrient substances in a full-water-soluble chelating mode. According to the hydrogel plant nutrient composition prepared through 3D printing, a network system formed by biodegradable macromolecules is soft in property, can keep a good shape, can absorb a large amount of water and can contain high-concentration nutrient substances. Nutrient substancesin the hydrogel are dispersed in the whole soil in a form which is easier to absorb by crops, so that nutrient loss can be reduced, the utilization rate of the fertilizer is greatly improved, and theyield and quality of the crops are improved.

Description

Technical field[0001]The invention relates to a hydrogel plant nutrient composition and a preparation method thereof, in particular to a hydrogel plant nutrient composition prepared by using 3D printing technology and a preparation method thereof, and belongs to the field of fertilizers.Background technique[0002]Because of its high precision and strong maneuverability manufacturing characteristics, 3D printing is now developing rapidly in the field of medical, clinical and scientific research. Hydrogels can simulate natural tissues due to their three-dimensional network structure. As bio-paper in three-dimensional bioprinting, it can meet morphological requirements and support cell proliferation. It can be used as a scaffold for cell growth, which has attracted widespread attention.[0003]At present, synthetic hydrogels can be mass-produced on a large scale, and have the advantages of fine-tuning structure and performance, good repeatability, easy processing, and strong mechanical pr...
