盘山县耕地土壤肥力状况研究

摘要

A total of 195 soil samples were collected in Panshan County to make analysis on 16 soil nutrient indexes, including their or-ganic matter, total nitrogen, available nitrogen, available phosphorus, available potassium, available silicon, sulfur, and exchangeable cal-cium. The results showed that soil in Panshan County is seriously in short of nitrogen, while phosphorus content is medium, and potassi-um content is rich. There is basically no lack of middle elements except that of calcium. As for microelements, they are all rich in con-tents except boron.%在盘山县采集土壤样品195个，对有机质、全氮、碱解氮、有效磷、速效钾、有效硅、有效硫、交换性钙等16项土壤养分指标进行测试分析。结果表明，盘山县土壤氮素严重缺乏，磷素含量中等，钾素含量丰富，中量元素除钙素外基本不缺，微量营养元素硼缺乏，其他很丰富。
