Abstract:The investigation on soil microelements in Tianjin Xiaozhan Rice Planting Area found that the total contents of Fe, Mn, Zn and S were in the high levels while B, Mo and Se were in the low levels; The available contents of Fe, Cu, Mn and S were greater than their critical values, Mo was in the medium level, whereas Se was in the low level. Correlation analysis found positive correlation existed between the total and available contents of Cu, Mn, B, Mo, Se and S except for Fe and Zn. Significant correlation was found between organic matter with available Cu, Fe, Mo, Se, S and Mn, pH played an important role in changing the availabilities of Mn and Se, and there was significantly positive correlation between water soluble salts with Fe, B and S. For paddy soil in Tianjin, it is necessary to apply microelement fertilizers combined with organic fertilizer and properly regulating soil pH. This study can provide important theoretical and practical instructions for the improvement of paddy soil and rice quality.
