吉林省中部土壤元素含量与pH相关性分析
Correlation Analysis between Contents of Soil Elements and pH in the Middle of Jilin Province
摘要
Abstract
[ Objective] The research aimed to study the effects of the soil acidity on the crop growth conditions. [ Method] GPS was used to collect 90 field points of the surface soil samples in the middle of Jilin Province. And X fluorescence spectrometric method was used to determine the contents of the soil elements. The statistical methods were used to analyze the correlation between the contents of soil elements and pH. [ Result ] There was a highly significant positive correlation between K, Ca, Mg and pH in the surface soil of the study area, which showed that the content of K, Ca and Mg would lose with the increase of soil acidity. The contents were lower than the average of Jilin Province. It had a significant negative correlation between N content and pH, which showed that N content would accumulate with the reduction of pH. It had a highly significant negative correlation between Cr, Pb, Hg and pH, which showed that the content of Cr, Pb, Hg and As would accumulate with the increase of soil acidity. [ Conclusion] Reasonable fertilization and the scientific farming methods should be adopted to protect and improve the environmental quality of the soil.关键词
