| 摘 要： | 研究了天津市农田不同农业利用方式下的土壤微量元素铁、锰、锌、铜、硼的有效态含量,结果表明:天津市农田土壤普遍存在缺锌问题,部分土壤缺锰,而土壤有效态铁、铜、硼含量比较丰富。今后在制定农作物高产施肥计划时应注意锌、锰肥的施用。

| Abstract: | The soil availability contents of Fe,Mn,Zn,Cu and B of farmland in Tianjin were studied.The result showed that Zn was deficient in large areas and Mn was deficient in some areas,while the contents of available Fe,Cu and B were comparatively rich.So,the application of Zn and Mn fertilizer should be considered in the plan of crop high-yield fertilization. |
