Abstract: In order to study the effects of different planting years on the stoichiometric characteristics of Camellia oleifera soil in Fujian mountainous area, the main chemical properties and stoichiometric characteristics of Camellia oleifera soil under different planting years were systematically studied. The results showed that the optimal characteristics of soil nutrients in different planting years of Camellia oleiferawere in 2021, and gradually increased from 2018 to 2021. The soil of Camellia oleifera cultivated for a long time tends to be further acidified. Under different planting years, the ecological stoichiometric characteristics changed little, and the difference value was not big, basically close.
