The results indicated that change regulations of N, P and K elements in fruits, leaves and soils of three cultivars of early ripening pear were basically consistent. The correlation analysis results of the three cultivars were similar, and N, P and K element contents in soils had no significant correlation with fruits and leaves. Keywor
