| 摘 要： | 采用大田定位试验,研究了氮磷钾与锌肥配施对小麦和玉米产量及Zn含量的影响。结果表明：在土壤有效Zn含量高于1.20 mg/kg的土壤上施用Zn肥,小麦和玉米增产效果不明显。不同施肥处理的小麦和玉米植株的Zn含量及Zn吸收量存在明显差异。土施Zn肥能显著提高小麦和玉米籽粒的Zn含量及Zn吸收量。与氮磷钾配施相比,氮磷钾配施锌肥小麦籽粒的Zn含量和Zn吸收量分别提高25.0%和25.7%,玉米籽粒的Zn含量和Zn吸收量分别提高12.0%和13.0%。

| Abstract: | The effects of combined application of nitrogen,phosphorus,potassium and zinc fertilizer on the yield and zinc content of wheat and maize were studied using field experiment.The results showed that the application of zinc fertilizer had no significant influence on the yield of wheat and maize,when the soil zinc content was higher than 1.20 mg/kg.The zinc content and uptake of wheat and maize had significant difference among different fertilization treatments.Zinc content and uptake in the grain of wheat and maize could be significantly increased by the application of zinc fertilizer.Combined application of nitrogen,phosphorus,potassium and zinc fertilizer,the zinc content and uptake in wheat grain could be increased by 25.0% and 25.7%,and those in maize grain could be increased by 12.0 % and 13.0%,respectively. |
