将梅列区耕地土壤检测结果与1982年土壤普查结果进行对比分析,结果表明:耕地土壤有机质含量下降明显,磷素含量增加明显,钾素含量有所提高,但处于缺乏水平的面积仍然很高,pH值略有下降;交换性镁缺乏,有效硼严重缺乏,碱解氮及有效硫含量水平中等偏低,有效锌含量丰富;经济作物类田块整体土壤养分含量较高,pH值较低。同时提出相应的施肥对策。
The results of soil test in the Meili district were compared with the results of the soil survey in 1982. The results showed that the content of organic matter in cultivated land decreased obviously, the content of phosphorus increased obviously, and the content of potassium increased, but the area of lacking level was still high , pH decreased slightly; lack of exchangeable magnesium, a serious lack of available boron, moderately low levels of available nitrogen and available sulfur, effective zinc content; the economic crop field of higher overall soil nutrient content, pH value is low . At the same time put forward the corresponding fertilization measures.
