Abstract:The geochemical properties of the soils at the apple-pear production regions in Yanbian were studied to understand the relationship between soil and fruit quality. The results indicated that in the four apple-pear main production regions, i.e., Longjing, Sanhe, Tumen and Hunchun,the mean contents of soil rare-earth elements were 169.13 mg/kg, 227.45 mg/kg, 159.59 mg/kg and 130.91 mg/kg respectively. In the four production regions, the value of (La/Sm)N was higher than 1, the value of (Gd/Yb)N was slightly higher than 1, δCe value was near 1, δEu value was lower than 1. REE levels in all soil samples except those from Sanhe region were under the mean level 186.8 mg/kg of China Mainland. The content curves of REE followed the Oddo-Harkin rule strictly, presented the logarithmic distribution. LREE and HREE separate obviously, showing light REE enrichment and negative Eu anomaly, and REE level was affected mainly by the parent materials. There was some differences in REE content between the top and bottom of a slope, but the soil usage patterns produced little effect on REE distribution.
