摘　　要：The annual dynamic changes of nutrient content in soil and leaves of adult Areca catechu trees in the A.catechu producing area Tunchang were studied by fixed point observation method to provide the scientific basis for the rational fertilization of A.catechu.The results showed that the soil of the A.catechu plantation was weakly acidic on the whole,and soil pH was 5.53.Soil phosphorus content was extremely low,only 5.46 mg/kg.Nitrogen content in A.catechu leaves was the highest( up to 20.24 g/kg),while phosphorus content was the lowest( only 0.31 g/kg).The differences in nutrient content were related to the characteristics of nutrient demand.There was a difference in nutrient content of A.catechu leaves during the annual growth period.Because the maximum nutrient requirement period of A.catechu trees was from April to September,the important fertilization period of A.catechu trees was also from April to September.The annual dynamic changes of nutrient content in soil and leaves of adult Areca catechu trees in the A.catechu producing area Tunchang were studied by fixed point observation method to provide the scientific basis for the rational fertilization of A.catechu.The results showed that the soil of the A.catechu plantation was weakly acidic on the whole,and soil pH was 5.53.Soil phosphorus content was extremely low,only 5.46 mg/kg.Nitrogen content in A.catechu leaves was the highest( up to 20.24 g/kg),while phosphorus content was the lowest( only 0.31 g/kg).The differences in nutrient content were related to the characteristics of nutrient demand.There was a difference in nutrient content of A.catechu leaves during the annual growth period.Because the maximum nutrient requirement period of A.catechu trees was from April to September,the important fertilization period of A.catechu trees was also from April to September.
