| 摘 要： | 为了解衡东县耕地的地力状况,选取5 891个土样进行养分含量检测,与1980年第二次全国土壤普查土壤养分含量平均值进行对比分析。结果表明:衡东县耕地土壤偏酸性,有机质、碱解氮含量较高,有效磷含量适宜,速效钾的含量偏低,与1980年相比,pH值有所下降,其他均有所提升。

| Abstract: | In order to know the status of land capability of cultivated land in Hengdong County,5 891 soil samples were chosen to test content of nutrient,and then the results were compared with the average values of nutrient content in soil which was obtained from the second national soil survey in 1980.The results indicated that the soil in cultivated land in Hengdong County is weak acidity,the contents of organic matters and available nitrogen are higher,the content of available phosphor is suitable,and the content of available potassium is lower;in comparison with the results in 1980,pH value decreased but others all increased at now. |
