Abstract: The soil calcium, magnesium, iron, zinc, manganese content change in different grass years of pear orchard was studied. The surface (0-20 cm) and sub-surface (20-40 cm) soil in the orchard with golden pear[Pyrus pyrifolia (Burm.f.) ‘Nakai’] grown with grass for 3, 4 and 8 years, respectively, were compared with that of the clean cultivated pear orchard. The items were measured including soil total Ca, Mg, Fe, Zn, Mn by ICP-OES-Optima 8x00. Inter-row and inter-plant soils were both measured. In pear orchard with grass growing, the total Ca, Mg, Fe, Zn, Mn of inter-plant surface soil were increased 25.35%-58.00%, 8.83%-24.73%, 15.30%-40.55%, 17.93%-57.94%, 11.86%-28.12%; the inter-plant sub-surface soil were increased 11.44%-39.08%, 3.17%-38.53%, 6.69%-38.25%, 24.34%-55.81%, 3.31%-34.00%; the inter-plant surface soil were increased 24.36%-53.05%, 31.70%-63.81%, 33.58%-66.05%, 24.34%-55.81%, 35.79%-73.21%; the inter-plant sub-surface soil were increased 18.29%-52.92%, 27.77%-69.69%, 27.45%-72.19%, 19.02%-62.75%, 32.70%-81.69%. Sown grass significantly increased the total Ca, Mg, Fe, Zn, Mn in different layers of the inter-row and inter-plant soil, and the content of both elements show that 8 years>4 years>3 years> clean cultivated, and sub-surface soil higher than surface soil, inter-plant higher than inter-row.
