Inoculation with Potassium Solubilizing Bacteria and Its Effect on the Medicinal Characteristics of Paris polyphylla var. yunnanensis

Potassium (K) use efficiency in Paris polyphylla var. yunnanensis production is relatively low, and the excessive of K fertilization has negative environmental impacts. Bacterial isolates can effectively alleviate this situation. The present work aimed to analyze effects different combinations three potassium-solubilizing bacteria (KSB) (Bacillus thuringiensis, B. polymyxa, Paenibacillus amylolyticus) on soil P. yunnanensis. results showed that contents forms were increased after application KSB. Compared with control group, maximum increases slow-acting K, available quick-acting exchangeable water-soluble 32.6% under inoculation both amylolyticus 73.5% 114.0% 83.2% amylolyticus, 210.0% respectively. This promoted conversion form high plant availability. Pseudo-protodiosgenin diosgenin H improved by KSB inoculations, which medicinal quality Correlation analysis there significantly positive correlations among five all experimental groups. In conclusion, availability yunnanensis, providing a path for sustainable
