| 中文摘要: |
| 对采集的数据按平均值加标准差法进行异常值剔除后，用Excel、SPSS软件对几种有效态与对应全量、pH、有机质含量和相关性进行了统计及分析，结果为:K、速效磷、有效硼含量处于稍缺乏状态，其余处于丰富或很丰富水平。不同pH条件下，有效态与对应全量、pH、有机质相关性各异:在强酸至碱性总体样本中，各有效态与对应全量均呈极显著正相关。各有效态与特定pH值呈极显著或显著正或负相关；碱解氮与有机质呈极显著正相关；速效磷、有效硼、有效锌与有机质在特定pH条件下呈极显著或显著正或负相关。结论对全县农作物平衡施肥、耕地提质改造具有指导意义。 |
| 英文摘要: |
| After eliminating outliers from the collected data by means of mean value plus standard deviation, the statistics and analysis of several effective states and their corresponding full amount, pH, organic matter content and correlation were carried out by using Excel and SPSS software, the results showed that the contents of K, available pHospHorus and available Boron were slightly deficient, and the rest were rich or very rich. Under different pH conditions, the correlation between the effective states and the corresponding total, pH, organic matter was different: In strong acid to basic samples, the correlation between the effective states and the corresponding total was very significant positive. There were significant positive or negative correlation between available states and specific pH value, significant positive or negative correlation between available n and organic matter, significant positive or negative correlation between available P, available B, available Zn and organic matter under specific pH condition. Conclusion it has guiding significance for the balanced fertilization of crops and the improvement of cultivated land quality in the whole county. |
