中文摘要：

采用盆栽试验，通过玉米-小麦和大豆-小麦轮作，探讨了不同种植模式中，土壤残留硒锌对小麦产量与营养品质的影响。结果表明，土壤中残留硒锌对小麦生物量和产量的影响与作物轮作体系有关。玉米-小麦轮作，土壤残留硒锌并没有表现出增加小麦产量的趋势，而大豆-小麦轮作，土壤残留硒锌对小麦生物量和产量呈增加趋势。土壤残留硒锌可改变作物体内元素组成。玉米-小麦轮作，土壤残留硒锌有利于小麦籽粒对氮、钾、硫、钙、铁、锌、硒、铜元素的吸收累积。大豆-小麦轮作，土壤残留硒锌促进小麦对钾、硫、镁、铁、锌、硒、铜、锰、硼的吸收，而氮、磷、钙吸收减少。

英文摘要：

Pot experiments were conducted with maize-wheat rotation and soybean-wheat rotation to study the effects of soil residual Se and Zn on wheat yields and nutritional quality. Obtained results showed that effects of soil residual Se and Zn on wheat biomass and yield were different with rotation systems. In maize-wheat rotation, soil residual Se and Zn did not show the trend to increase wheat biomass and yields, but significantly increased the wheat biomass and yields in soybean-wheat rotation; Soil residual Se and Zn could change the composition of elements in crops. In maize-wheat rotation, N, K, S, Ca, Fe, Zn, Se, and Cu contents of wheat grain were significantly increased by soil residual Se and Zn. In soybean-wheat rotation, grain K, S, Mg, Fe, Zn, Se, Cu and B contents significantly increased, but N, P, Ca and Mn contents decreased.
