摘要
为了解上张乡土壤质量水平,对耕作层土壤样品进行采集、测试分析;取得了上张乡农用土地中不同利用方式的田块土壤养分、微量元素有效态和土壤环境等数据,通过分级-赋值给分-综合评价等步骤,确定了上张乡3种利用方式中各田块的土壤肥力、土壤环境等级、微量元素含量水平。评定结果为:该乡农田质量环境优良,综合肥力中等,部分田块肥力不足,主要表现为缺磷;微量元素铁、锌丰富,硼缺乏;旱地质量环境优良,综合肥力中等,局部肥力偏低,微量元素铁、锌丰富,缺铜、硼;园地质量土壤环境优良,综合肥力中等为主。有效微量元素铁、锌丰富,少锰缺铜、硼;上张乡土壤质量评定对合理确定土地功能和价值,优化土地利用规划,科学利用土地资源的具有现实意义。
In order to find out the level of the soil quality in Shangzhang Country,the paper collected the soil sample in plough layer in different land use types.By testing and analyzing the sample,the data of soil nutrients,available trace elements,and of the soil environment were obtained.The paper defined the level of soil fertility,soil environment,and the content of trace elements by classifying,scoring,and comprehensive evaluating.The results showed that the farm land environment was good in Shangzhang Country,the soil comprehensive fertility was middle level and some lands lacked fertility especially for Phosphorus.Meanwhile,the trace elements such as Fe,Zn were rich and B was lack.The condition of dry land was good,and its comprehensive fertility was middle level but some was low,and the trace elements Fe,Zn were rich while Cu and B were lack.The garden land quality was good and the fertility was middle,its available trace elements Fe and Zn were rich and Cu and B were lack.Quality comprehensive assessment of farm land in Shangzhang Country had practical significance in confirming land function and value reasonably,optimizing land utilization plan,and using land resources scientifically.
