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 understand the soil quality level in Shangzhang Township, the soil samples in tillage layer were collected, tested and analyzed. The data of soil nutrients, available trace elements and soil environment of different utilization ways in Shangzhang rural land were obtained, Assignment to the points - comprehensive evaluation and other steps to determine the use of Shangxiang three plots of soil fertility of each field, soil environmental levels, trace element levels. The results are as follows: The quality of farmland in this township is good, the comprehensive fertility is moderate, and some of the plots are deficient in fertility. The main manifestations are lack of phosphorus, trace elements iron and zinc, abundant boron, lack of boron, quality and environment of dry land, medium comprehensive fertility and low local fertility , Trace elements iron, rich in zinc, lack of copper, boron; garden quality soil environment is good, comprehensive fertility medium. The available trace elements of iron, zinc rich, less Manganese lack of copper, boron; Shang Zhang Township soil quality assessment of the rational determination of land function and value, optimize land use planning, scientific use of land resources of practical significance.
