Cyclocarya paliurus is a well-known multifunction tree species and especially its leaves are largely needed for the tea production and medical utilization in China. To meet the enormous requirements of its leaf production, lots of C. paliurus plantations for harvesting the leaves have been developed, while a large of pruning residues are produced during the management. In this study, the biochar at different pyrolysis temperatures (300°C, 500°C and 700°C) were prepared in the light of the pruning residues, and the effects of biochar additions pyrolyzed at different temperatures on soil properties, growth and leaf secondary metabolite accumulation in C. paliurus were investigated. The result showed that the chemical properties and FT-IR spectra of wheel wingnut-based biochar were significantly influenced by the pyrolysis temperatures, whereas the application of biochars pyrolyzed at different temperatures significantly affected the soil pH and nutrient availability, as well as the growth, nutrient uptake and secondary metabolite accumulation of C. paliurus seedlings (p < 0.05). Correlation analysis indicated that the total contents of polyphenols, flavonoids and triterpenoids in C. paliurus leaves were negatively correlated with the contents of total phosphorus (P) and total potassium (K) in the leaves, but positively correlated with the ratios of carbon (C)/nitrogen (N) and C/P. After 200 days of biochar treatment, the highest biomass production and leaf secondary metabolite accumulation in C. paliurus were obtained in the addition of biochar pyrolyzed at 500°C. The findings from this pot experiment provide a potential application in C. paliurus plantation, though the long-term field experiments are required to optimize the biochar addition quantity based on the soil conditions and stand age at the planting sites.
