摘　　要：对东港市水稻田主产区1151个土壤样品的有机质、速效氮、有效磷、速效钾、pH值、铁、锌等微量元素进行土壤养分指标测定分析,并与第2次土壤普查资料进行数据对比。结果表明:东港市目前水田土壤有机质缺乏,氮素含量中等偏高,磷素含量稍丰,钾素含量中等偏低,有效铁、锰含量很丰富,有效铜含量中等,有效锌含量不足。同时,根据不同区域,提出相应的施肥建议。The soil nutrient indexes are determined and analyzed in terms of such trace elements as organic matters,available nitrogen,available phosphor,available potassium,pH values,ferrum,and zinc from the 1 151 soil samples collected at the major rice production areas in Donggang city.The obtained figures are compared with the data from the second soil census.The findings show that the organic matter in the soil is insufficient,the nitrogen content is slightly on the high side,phosphor content is somewhat adequate,potassium content is on the low side,and there is a rich content in ferrum and mangan.Accordingly,the author puts forward various fertilization proposals in light of the different situations in different regions.
