| 摘 要： | 对江苏省响水县1984年与2010年2次地力评价所涉及的土壤有机质含量、有效磷含量、速效钾含量、pH值、耕层厚度等评价指标因子的变化进行了对比分析。结果表明：响水县耕地地力总体呈上升趋势。针对该县地力变化趋势,提出了增施有机肥、开展测土配方施肥、进行深耕深松、系统地进行耕地质量监测等应用对策。

| Abstract: | The soil organic content,available phosphorus content,available potassium content,pH value and thickness of cultivated land in the cultivated land fertility evaluation index of 1984 and 2010 in Xiangshui County of Jiangsu Province were compared.The results indicated that the cultivated land fertility showed an increasing tendency.Based on the changing trend of cultivated land fertility,the application countermeasures were put forward including applying organic manure,developing soil testing and formulated fertilization,applying deep plowing and scarification techniques,and monitoring systemically the cultivated land quality. |
