摘　　要：为了探讨小麦生长期内,在底肥施用氮、磷、钾肥的基础上,叶面喷施微量元素肥料对产量、籽粒、茎叶中含量的影响。用众麦99为材料,在安阳市农业科学院柏庄基地进行试验,在小麦拔节中期和抽穗初期,对叶面喷施一定含量的锌、铁、硒肥。结果表明,喷施微量元素肥料对产量及其三因素都有不同程度的影响,千粒重提高,有效穗数减少,锌和铁肥在茎叶、颖壳、籽粒都有拮抗作用,硒肥和锌、铁肥之间在茎叶、颖壳、籽粒都有抑制作用;喷施硒肥籽粒、茎叶、颖壳含量都增加,易形成富硒作用。The purpose of this study was to investigate the effects of foliar spraying microelement fertilizer on wheat yield,grain,stem and leaf contents on the basis of base fertilizer application of N,P and K during wheat growth period.Using Zhongmai 99 as material,the experiment was carried out in the Bozhuang Base of Anyang Academy of Agricultural Sciences.In the middle jointing and early heading stage of wheat,the fertilizer of zinc,iron and selenium with certain content was sprayed on the leaves.The results showed that spraying microelement fertilizer had different effects on yield and its three factors.The 1000-grain weight increased and the number of effective panicles decreased.The zinc and iron fertilizer had antagonistic effects on stem,leaf,glume and grain,while the selenium fertilizer and zinc and iron fertilizer had inhibitory effects on stem,leaf,glume and grain.Spraying selenium fertilizer increased the contents of grains,stems,leaves and glumes,and it was easy to form selenium enrichment.
