摘　　要：通过盆栽试验研究了燕麦/小麦轮作和混作对小麦锰营养的影响。结果表明,不同品种的小麦耐缺锰能力不同,表现为9023>川麦28。与燕麦轮作或混作均未能改善小麦的锰营养,并且还抑制其生长;与单作相比,混作降低了小麦的地上部吸锰量;而叶面喷施锰肥则显著促进了小麦生长,明显改善其锰营养。The pot experiment was conducted to investigate the effects of oat/wheat rotation and mixed cropping on Mn nutrition of wheat. The results showed that the endurance of different wheat cultivars to Mn lack was different, namely 9023〉Chuanmai28. Mn nutrition of wheat was not significantly improved by rotation or mixed cropping with oat in this experiment, and wheat shoot biomass was reduced. Moreover, shoot Mn uptake of wheat was markedly decreased by mixed cropping with oat compared with monocropping. But the growth and Mn nutrition of wheat were evidently improved by applying MnSO4 fertilizer which sprayed over the leaves.
