| 摘 要： | 田间小区试验结果表明,山东省胶东半岛地区花生种植的养分限制因子,除了氮、磷、钾是花生产量的主要限制因子外,营养元素锌和镁也是胶东地区花生生产的主要限制因子;过量施用氮肥或氮、磷、钾比例失调易造成花生减产;施肥主要通过影响花生百果重、每墩总果数、单/双仁饱果数和秕果数等影响花生产量。缺钾处理的花生茎秆和叶片钾含量明显低于其它施钾处理。

| Abstract: | Through field experiments,limiting nutrient elements to peanut were studied at Jiaodong Peninsula in Shandong Province.The results showed that zinc and magnesium were the main limiting factors to peanut yield,besides nitrogen,phosphorus and potassium,in Jiaodong areas.Excessive nitrogen or imbalanced fertilization ratio of nitrogen,phosphorus and potassium could reduce peanut yield.Fertilization affected peanut yield mainly through impacting on 100-pod weight,total pod quantity,single/double full pod number and unfulfilled pod number per cluster.Potassium content in stems and leaves of the treatments with no potassium applied(CK and OPT-K) was significantly lower than that of other treatments. |
