| 摘 要： | 为给旱薄区夏玉米的优质高产栽培提供依据,研究了不同矿质元素N、P、K和Zn对夏玉米生长发育过程中的器官干物质积累、分配和转移的影响效应。结果表明,不同矿质元素及其组合,对于夏玉米的器官干物质积累、分配和转移均有一定影响;NK配合施用,优于单一N肥的施用,NPK配合施用,优于NK配合施用,NKZn配合施用,优于NK及NPK配合施用;NK与微肥Zn配合施用的经济系数最高为(0.56),对于防止后期叶片早衰、促进地上部器官干物质积累、提高籽粒产量,均具有重要作用。 |

| Abstract: | The relationship of dry matter accumulation, distribution and transfer of organs of summer maize was studied.The results revealed that combinational application of mineral elements has effect on the dry matter accumulation,distribution and transfer of organs of summer maize.NK fertilizer application was superior to N,NPK was more effectively than NK and NKZn was better than NK,NPK.NKZn combined fertilization,it's important to enhance the leaf area index,delay the late stage of leaf early senescence,accelerate dry matter accumulation,accelerate grain filling and enhance final volatile yield. |
| Keywords: | summer maize NPK micronutrients combined application dry matter |
