摘要
微量元素是农作物产量高低和质量好坏的限制因子.为了经济合理地施用微量元素肥料,对佳木斯市主要土壤中微量元素的含量作了基础性的评价和分析工作,结果表明即多数土壤有效态硼和锌缺乏;大多数土壤有效态铜、锰和铁较为丰富.
Trace elements play a predominant role in the productivity and quality of crops. To use the fertilizers containing trace elements economically and reasonably, some evaluation and analysis to the contents of trace elements in the main soil of Jiamusi area. The results indicate that in the majority of soil the valid contents of B and Zn are short, and the valid contents of Cu, Mn and Fe are abundant.
