通过对新罗区2003年268个和2010年400个稻田土样检测结果进行分析，结果表明：稻田土壤经过7a的耕作与时空变化，速效钾含量明显升高，由2003年的缺乏水平提高至中等水平；有机质含量虽略有下降，但仍在较丰富水平；全氮、有效磷含量仍维持在中等水平；乡镇之间土壤肥力不均衡，差异较大。据此提出相应的施肥建议。

The testing results of 268 and 400 paddy soil samples at Xinluo district in 2003 and 2010 respectively were analyzed. The results showed that paddy soil passed farming and space-time change of seven years, its available potassium content obviously increased from the lack level in 2003 to the middle level, its content of organic matter was declined slightly but still in a relatively rich level; the contents of total nitrogen and available phosphorus still remained at medium level. Soil fertility between different towns was not balanced and had a larger difference. So the corresponding fertilization suggestion was put forward according to these analytical results.
