据辛集市农技中心土肥站对全市土壤养分检测结果显示:有机质、有效氮、有效钾含量不同程度的增加,而有效态的微量元素铁、钼、锰、锌等下降严重。根据土壤养分的丰缺指标和检测结果,补充中、微量元素,可以有效减少植物病害,也是作物丰产的关键措施。生产中,农民由于不平衡使用养分,导致某些营养元素过多或过少,造成作物生长异常,如: According to Xinji City Agricultural Technology Center soil fertilizer station soil nutrients test results showed that: organic matter, available nitrogen, available potassium content increased to varying degrees, and the effective state of trace elements such as iron, molybdenum, manganese, zinc and other serious decline. According to the index of abundance and deficiency of soil nutrients and test results, adding trace elements and trace elements can effectively reduce plant disease and is also the key measure for the high yield of crops. In production, due to the unbalanced use of nutrients by peasants, some nutrients are too much or too little, causing abnormal crop growth. For example,
