淮安市清浦区土壤微量元素含量与有效性分析

Contents and Correlation Analysis of Microelements in soil of Qinpu,Huai'an

通过对淮安市清浦区土壤微量元素状况进行研究,结果表明,清浦区稻麦轮作土壤微量元素有效态铁、锰、铜、锌、硼平均值都高于土壤养分含量临界值,但分布不均匀。有效态铁、有效态铜较丰富,基本不缺乏;有效态锰、有效态锌、有效态硼分别有21.25%、37.50%、15.00%的样品低于土壤养分含量临界值。文章在研究土壤微量元素含量的基础上,分析了其与土壤有机质和土壤pH值的相关性,为科学施肥提供了重要的参考依据。

The soil availability microelements of farmland in Qingpu were studied, The result showed that the average contents of Fe,Mn,Cu,Zn and B were greater than the critical value, which distribution was not uniform. The contents of available Fe, Cu were comparatively rich. The percent of the sample that contents of available Mn,Zn,and B under the critical value were 21.25%, 37.50%, 15.00%. Based on study of microelements＇ contents in soil, soil organic matter and pH value related were analyzed. All the results provided the theoretical basis for scientific fertilization of the soil.
