　　在冀西山区水浇地条件下，以玉米品种浚单20、邢抗2号、承玉5号、郑单958和泰玉2号为试验材料，采用相同的栽培措施，探讨了不同品种的产量差异以及土壤、植株、籽粒中的氮磷钾和有机质含量状况。结果表明：参试玉米品种的产量顺序为郑单958＞浚单20＞泰玉2号＞邢抗2号＞承玉5号，其中，郑单958与浚单20产量差异不显著，但二者均显著＞承玉5号。参试品种不同生育期的土壤有机质和有效磷含量以及植株全钾含量顺序均为苗期＞大喇叭口期＞收获期；可能受大喇叭口期追肥的影响，土壤碱解氮含量顺序为大喇叭口期＞苗期＞收获期，植株全氮含量顺序为收获期＞苗期＞大喇叭口期，植株全磷含量顺序为苗期＞收获期＞大喇叭口期。产量与土壤、植株、籽粒中的氮磷钾及有机质含量间没有表现出明显的相关性。与该区域旱地玉米相比，同一品种的产量差异变化明显，这说明不同玉米品种所适应的种植条件明显不同。

Taking maize varieties Jundan 20, Xingkang No.2, Chengyu No.5, Zhengdan 958 and Taiyu No.2 as the test materials, the yield of different maize varieties, the contents of nitrogen, phosphorus, potassium and organic matter of soil, plant and grain in irrigated land of west mountain regions of Hebei Province were analyzed using the same cultivation.The results showed that the orders of the yield of different maize varieties was Zhengdan 958>Jundan 20 >Taiyu No.2 >Xingkang No.2 >Chengyu No.5.There was no significant difference on yield between Zhengdan 958 and Xundan 20 , but both was significantly higher than that of Chengyu No.5.From high to low, the orders of organic matter and available phosphorus contents of soil , the total potassium content of plants of different growth stages were seedling stage, large bell stage, harvest stage, the order of soil available nitrogen content was large bell stage, seedling stage, harvest stage, the order of total nitrogen content of plants was harvest stage, large bell stage, seedling stage, the order of total phosphorus content of plants was seedling stage , harvest stage, large bell stage, which may be affected by fertilizer effect of nitrogen in large bell stage.The yield was not obvious correlated with nitrogen, phosphorus and potassium in soil, plant and grain as well as soil organic matter content.Compared with dryland maize of the region, the difference of same variety on yield was significant, which indicated that different maize varieties were suitable for different planting conditions.
