摘 要:[Objectives]This study was conducted to investigate the correlation between leaf blight of pearl plum and nutrient elements from the perspective of plant nutrition.[Methods]Branch and leaf samples of pearl plum plants infected by or free of leaf blight and the corresponding 0-30 cm cultivated soil were collected,and statistical analysis was conducted according to the changes in nutrient contents and the incidence of leaf blight,so as to look for nutrients in pearl plum plants associated with leaf blight,as well as soil constraint factors.[Results]Phosphorus,iron and manganese in nutrients may be related to leaf blight,and the factors affecting leaf blight may be the ratios of P/Fe and P/Mn in leaves.[Conclusions]This study provides a basis for further research on the relationship between phosphorus,iron and manganese on the effect of leaf blight in pearl plum trees.
