Description

Technical Field

[0001] The present invention relates to the field of agricultural biotechnology, and specifically to a plant growth-promoting compound formulation containing polyglutamic acid, aminobutyric acid, pollen polysaccharide, and enzyme, and its preparation method. The compound formulation can significantly promote plant growth, increase crop yield and quality, and enhance plant stress resistance. Background Art

[0002] Plant growth regulators play an important role in agricultural production, improving crop yield and quality. Currently, most commonly used plant growth regulators are chemically synthesized substances, and long-term use can lead to soil compaction and environmental pollution. Therefore, the development of efficient, environmentally friendly, and safe plant growth promoters is of great significance.

[0003] Polyglutamic acid (γ-PGA) is a natural polymer that retains water and promotes nutrient absorption; GABA is a non-protein amino acid that enhances plant resistance to stress; pollen polysaccharides are polysaccharides extracted from plant pollen that enhance plant immunity; and enzymes promote the decomposition of organic matter in the soil, improving nutrient utilization. However, there are currently no reports of the combination of these four ingredients being used to promote plant growth. Summary of the Invention
