| 摘 要： | 2000年海淀区农田耕层土壤养分普查结果表明,全区土壤养分含量整体处于中等水平以上。其中,有机质含量达到17 1g/kg,有效磷和有效钾含量分别达到78 9mg/kg和144 5mg/kg。不同农田类型土壤养分含量差异明显,菜地高于果园,果园高于粮田。与1980年海淀区全国第二次土壤普查结果相比,土壤有机质略有下降,土壤有效磷含量大幅提高。文章还对土壤养分的变化的原因进行了分析。

| Abstract: | Soil nutrients analysis was carried out in Haidian District in 2000. It was showed that soil nutrients content in Haidian was at middle level in general. The mean value of Soil organic matter, Olsen-P and HA-K was 17.1g/kg, 78.9mg/kg and 144.5mg/kg, respectively. A remarkable difference for soil nutrients content among three land use types was found, which was vegetable field, orchard field and cereal field in sequence. Compared with the results from 1980, there was a little reduction for soil organic matter, but a sharply rise for Olsen-P. The reason of soil nutrients change was analyzed. |
