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