Abstract

Abstract: To screen high-efficiency root dressing agent formulations and investigate their effects on the growth, quality, and soil physicochemical properties of Polygonatum kingianum Collett & Hemsl., two-year-old seedlings of Polygonatum kingianum were used as experimental materials. Nine fungicides were combined into four root dressing treatments (A1 to A4) and a control (CK). The results showed that, compared with CK, the root dressing treatments significantly improved the emergence rate, seedling survival rate, and disease resistance of Polygonatum kingianum. Among them, treatment A1 (80% tetramycin + 5% thiram + 15% captan) performed the best, with emergence and seedling survival rates of 95.75% and 95.25%, respectively. The incidence of root rot in August and September (1.25%, 4.75%) was significantly lower than that of CK (34.00%, 49.25%). Plant height (114.58 cm) and yield (4 675 kg/hm²) increased by 15.57% and 168%, respectively, compared to CK. The contents of polysaccharides, total flavonoids, and total saponins increased by 16.30%, 32.46%, and 15.11%, respectively, compared to CK. Additionally, the root dressing agent increased soil pH and alkaline hydrolyzable nitrogen content but led to a decrease in soil organic matter content.

Key words: Polygonatum kingianum Collett & Hemsl., root dressing agent, agronomic traits, medicinal components, soil physicochemical properties
