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: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;pH以酸性为主。不同pH条件下,有效态与对应全量、pH、有机质相关性存在差异性:酸性条件下,各有效态与对应全量均呈极显著正相关;碱解氮、速效磷、有效硼、有效钼与特定pH值呈极显著或显著正或负相关;碱解氮与有机质呈显著或极显著正相关;速效磷、有效钼、有效锌与有机质在特定pH条件下呈极显著或显著相关。分析结果为农作物平衡施肥、耕地提质改造、促进全域土地综合整治提供了基础依据。
英文摘要:
      After removing the abnormal values of the collected data by the method of average plus standard deviation, the statistics and analysis of several effective States and the corresponding total amount, pH, organic matter content and correlation were carried out by using Excel and SPSS software. The results are as follows: the content of available phosphorus and available boron is in a slightly short state, the rest is in a rich or very rich level; the pH is mainly acid. Under different pH conditions, the correlation between the available state and the corresponding total amount, pH and organic matter is different: under acid conditions, the correlation between the available state and the corresponding total amount is extremely significant; alkali hydrolyzed nitrogen, available phosphorus, available boron and available molybdenum are extremely significant or significant positive or negative correlation with specific pH value; alkali hydrolyzed nitrogen is extremely significant or significant positive correlation with organic matter; available phosphorus, available molybdenum and available zinc are extremely significant or positive correlation with specific pH value Organic matter is highly significant or significantly correlated at specific pH value. The results provide the basic basis for balanced fertilization of crops, improvement of cultivated land quality and promotion of comprehensive land improvement.
