摘要： 为探讨不同生草年限梨园土壤钙、镁、铁、锌、锰含量变化，在东营市孤岛镇12年生‘黄金梨’[Pyrus pyrifolia (Burm.f.) ‘Nakai’]种植园，设置生草3年、生草4年和生草8年3个处理，以清耕梨园为对照，通过电感耦合等离子体发射光谱仪分别测定株间和行间表层(0~20 cm)和亚表层(20~40 cm)土壤钙、镁、铁、锌、锰的含量。梨园生草后，土壤全钙、全镁、全铁、全锌、全锰含量均有所升高。株间表层(0~20 cm)土壤分别升高25.35%~58.00%，8.83%~24.73%，15.30%~40.55%，17.93%~57.94%，11.86%~28.12%；株间亚表层(20~40 cm)土壤升高11.44%~39.08%，3.17%~38.53%，6.69%~38.25%，17.87%~57.12%，3.31%~34.00%；行间表层(0~20 cm)土壤升高24.36%~53.05%，31.70%~63.81%，33.58%~66.05%，24.34%~55.81%，35.79%~73.21%；行间亚表层(20~40 cm)土壤升高18.29%~52.92%，27.77%~69.69%，27.45%~72.19%，19.02%~62.75%，32.70%~81.69%。梨园生草后能显著提高土壤各层全钙、全镁、全铁、全锌和全锰含量，且均表现为生草8年＞生草4年＞生草3年＞清耕。土壤全钙、全镁、全铁、全锌、全锰含量在不同土层中表现不一，但多随土壤深度增加而升高，且行间含量高于株间。

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.
