| 摘 要： | 微量元素对作物生长发育有重要作用。以锌、锰、铜、硼、铁等微量元素肥料在石灰性土壤上进行玉米肥效试验,收获时检测玉米茎、叶、籽实、芯的微量元素含量,并进行测产分析。结果表明,玉米增施微肥能有效增加籽实产量,与对照(不施微肥)相比差异达显著水平;但玉米的茎、叶、芯产量与对照相比差异不显著。另外施用微肥后玉米植株各部位微量元素含量未呈现一定规律的变化。

| Abstract: | Microelement fertilizer is very important to the growth of crop.In this study,microelement fertilizer containing Zn,Mn,Cu,B and Fe was applied on maize in calcareous soil.The content of the microelement in stems, leaves,grain and cores of maize and grain yield were analyzed at harvest stage.The results showed that the micro-element fertilizer could significantly increase the grain yield of maize as compared with control but the differences of the yields of stems,leaves and cores were not significant between the treatment and the control.In addition,the microelement content in different parts of maize plant did not vary with a regular pattern. |
