鲁西北地区冬小麦春季追肥情况调查

Investigation on Spring Top-dressing Fertilizer of Winter Wheat in Northwest Shandong Province

为了解鲁西北地区麦田春季追肥现状及存在的问题,在乐陵、阳信2个典型的农业县开展调查。结果表明,乐陵和阳信绝大多数农户施氮、施磷过量。其中乐陵地区过量施氮的农户达49.3%,过量施磷的农户达42.3%;阳信地区过量施氮的农户高达57.6%,过量施磷的农户达74.6%。此外,大多数农户钾肥施用不当。可见,当前农户在肥料施用上还较粗放,过量施肥问题普遍存在,农技推广部门应进一步加强科学施肥知识宣传和推广力度,提高农户科学施肥水平。

In order to understand the current situation and existing problems of wheat field management in the northwest Shandong Province, Shandong Province has carried out investigations in two typical agricultural counties, Laoling and Yangxin. The results showed that the majority of farmers in Laoling and Yangxin applied nitrogen and phosphorus excessively. Among them, the number of farmers who applied excessive nitrogen in the Laoling area was up to 49.3%, and that of the farmers who had excessive phosphorus application was up to 42.3%;the number of farmers who applied excessive nitrogen in the Yangxin area was up to 57.6%, and that of the farmers who had excessive phosphorus application was up to 74.6%. In addition, most farmers that have improper application of potassium fertilizer was unreasonable. It could be seen that the current fertilizer application of farmers was relatively extensive, and the problem of excessive fertilization was widespread. The agricultural technology promotion department should further strengthen the scientific propaganda and promotion of scientific fertilization knowledge and improve the scientific fertilization level of farmers.
