Organic fertilizer for promoting growth of plant root system and preparation method thereof

Abstract

This invention discloses an organic fertilizer that promotes plant root growth and its preparation method, relating to the fields of agricultural planting and fertilizer processing technology. The organic fertilizer for promoting plant root growth comprises the following components in parts by weight: 60-80 parts fermented organic matrix, 5-15 parts mineral-derived potassium humate, 3-8 parts enzymatically hydrolyzed seaweed extract, 5-10 parts compound amino acid powder, 0.05-0.5 parts root growth promoting factor, 0.5-2 parts microbial inoculant, and 2-5 parts binder. This invention utilizes an indole derivative with a specific structure as the core component, and leverages its unique side chains and functional groups to enhance chemical stability, making it less prone to thermal decomposition during fertilizer granulation and drying processes.
