In order to understand the nutrient status in soil and leaf of yield-invigorating and -debilitating pear orchards of ‘Sucui No.1’ in Jiangsu Province and provide the scientific basis for reasonable fertilization of pear orchards, soil and leaf samples were collected and measured from 20 ‘Sucui No. 1’ pear orchardes in the south, middle, and north of Jiangsu Province and nutrients were analyzed by the “Vegan” package in R software. The correlation between the nutrients in soils and leaves, and the measured soil and leaf nutrients were compared with the corresponding optimum standard values of pear orchard. The results showed that 90% of the orchards were within pH appropriate range of 5.6 - 7.2, and 90% of the orchards were suitable or abundant in organic matter (>1%), and 60% and 40% of the orchards were insufficient in alkaline nitrogen and available potassium, respectively, and 85% of the orchards were rich in available phosphorus. All the orchards were rich in soil exchangeable calcium and magnesium, 15%, 60% and 25% of the orchards were insufficient in soil available iron, manganese and copper, respectively. 15%, 65%, 25%, 25% and 90% of leaves were insufficient in nitrogen, phosphorus, magnesium, manganese and copper, respectively. Soil and leaf nutrients were significantly correlated with the orchard location and pear yield. The contents of soil organic matter, available phosphorus, iron, manganese and copper in yield-invigorating pear orchards were significantly higher than those in yield-debilitating ones. Meanwhile, the leaf nitrogen in yield-invigorating pear orchards was significantly higher than in yield- debilitating ones. In summary, contents of organic matter, available phosphorus, iron, manganese and copper in soil whereas contents of nitrogen, phosphorus, and potassium in leaves were different between yield-invigorating and -debilitating pear orchards, indicating that the diagnose of leaf nutrition and soil should be combined when fertilization regimes of pear orchards were constructed.
