Abstract

Relevance. In modern conditions, the issues of soil protection from heavy metal pollution attract the increased attention of researchers from different countries. This problem is especially acute for agricultural landscapes located near cities, industrial facilities and highways.Methods. The objects of research were the soils of agricultural landscapes of the Ufa district of the Republic of Bashkortostan. The studies were carried out on leached chernozem.Results. According to the data obtained, the content of heavy metals in soils and in spring wheat grain varies within the limits not exceeding the MPC level. When using mineral fertilizers in agrochernozem, there is a tendency to increase the content of mobile forms of heavy metals and their accumulation in spring wheat grain. Liming, application of manure and siderate contributed to a decrease in the content of heavy metals in the soil and a decrease in their intake into the grain of spring wheat. This indicates the possibility of directed regulation of grain quality by the use of agro-reclamation and agrotechnical techniques.
评估施用石灰和肥料对浸出农田土壤中重金属含量以及春小麦籽粒中重金属积累的影响
相关性。在现代条件下,保护土壤免受重金属污染的问题日益受到各国研究人员的关注。对于位于城市、工业设施和高速公路附近的农业景观而言,这一问题尤为突出。研究对象是巴什科尔托斯坦共和国乌法地区的农业景观土壤。研究对象是巴什科尔托斯坦共和国乌法地区的农田土壤。根据获得的数据,土壤和春小麦籽粒中的重金属含量在不超过 MPC 水平的范围内变化。在农用切尔诺泽姆中使用矿物肥料时,会增加重金属的移动形式含量及其在春小麦籽粒中的积累。施用石灰、粪肥和偏酸盐有助于降低土壤中的重金属含量,减少春小麦籽粒中的重金属摄入量。这表明有可能通过使用农业复垦和农业技术对谷物质量进行定向调节。
