Soil Fertility Quality Evaluation of Camellia oleifera Plantations in the Main Production Area of Northwest Guangxi Based on Minimum Data Set
Soil fertility quality in the main production areas of Camellia oleifolia plantations in northwest Guangxi was evaluated based on the Minimum Data Set(MDS).This study revealed the regional differences in soil fertility and their effects on the growth of C.oleifera,which provided scientific basis for management and soil improvement of C.oleifolia plantations.Soil samples were collected from various cities and analyzed for their fertility indicators.Principal Component Analysis(PCA)was employed to construct a soil fertility evaluation index system and to calculate its weights.The findings showed that indicators such as pH,organic matter,total potassium,alkali-hydrolyzed nitrogen,available zinc,and available boron had higher weights in the MDS and could effectively reflect soil fertility status.A comparison of the soil fertility quality indices derived from the Total Data Set(TDS)and the MDS revealed generally consistent rankings,although minor discrepancies were observed in certain areas.
