Objective  The fruit components of Cinnamomum (C.) migao affected by soil factors will be clarified in order to provide the basis of artificial cultivation for it.

  Method  Fruit nutrient components soil nutrients and enzyme activities were determined from 22 fruits and soil samples of C. migao collected from different areas. The main soil factors affecting the quality of C. migao fruits were screened by simple correlation analysis and multiple regression analysis.

  Result  The results showed that the nutrient composition, soil nutrient contents, and enzyme activities of C. migao fruit were different in areas. Different soil nutrients and enzyme activities had different effects on the nutrient composition of C.migao. Total sugar was mainly affected by soil total potassium (TK), available potassium (AK), and organic matter (OM). The reducing sugar was mainly affected by soil total phosphorus (TP), TK, AK, pH, and catalase (S-CAT). Soluble polysaccharide was mainly affected by soil TP, TK, AK, pH, and acid phosphatase (S-ACP). Crude polysaccharides were mainly affected by soil TP, TK, alkaline nitrogen (AN) and pH. Polysaccharides were mainly affected by soil TP, TK, AK, OM, pH, and S-ACP. The total flavonoids were mainly affected by soil TP, AK, OM, pH and S-ACP, urease and S-ACP. And the ether extract was mainly affected by soil TP, available phosphorus, AK, pH, urease, and S-CAT. Soil pH and TK were important factors affecting the fruit quality of C. migao, followed by TP, AK, OM, S-CAT and S-ACP activities.

  Conclusion  Therefore, increasing or decreasing soil nutrient contents is an important way to improve the yield and quality of C. migao fruit.
