摘　　要：对大石桥市玉米田土壤养分进行测定,并与第2次土壤普查数据进行比较分析。结果表明:大石桥市玉米田土壤有机质呈下降趋势;水解氮含量中等或略丰;有效磷含量大幅度上升,呈中等偏上水平;速效钾下降幅度较大;有效锌含量水平较低。同时,根据土壤养分含量的高低,提出了相应的施肥建议。Soil nutrient contents in the maize fields in Dashiqiao City are measured and comparisons are made with the second soil census data. The results show that there is a downward trend in the soil organic matters in the maize fields in Dashiqiao City, the content of hydrolysable nitrogen if of medium size of slightly above that, there is a substantial increase in the content of available phosphorus which is slightly above the medium size, there is a sharp decrease in the content of readily available potassium, and the content of available zinc is of a low level.
