新疆平原地区分布着大面积的盐碱土壤。据统计,在全疆三亿多亩荒地中,约1.1亿亩为盐碱土,在近五千万亩耕地中,约有三分之一的面积受到不同程度盐碱化威胁。随着易溶盐在土壤中的迁移和积累,某些微量元素也有其独特的变化规律。本文目的在于研究不同类型盐碱土中某些微量元素的含量和分布规律,以明确这些土壤中微量元素的丰缺情况,为改良土壤提供依据。
Xinjiang plain area with a large area of saline soil. According to statistics, of the 300 million mu of wasteland in Xinjiang, about 110 million mu are saline soils, and about one-third of the nearly 50 million mu of cultivated land is threatened with salinization to varying degrees. With the migration and accumulation of easily soluble salts in soil, some trace elements also have their own unique variation rules. The purpose of this paper is to study the content and distribution of some trace elements in different types of saline-alkali soil in order to clarify the abundance and deficiency of trace elements in these soils and provide basis for soil improvement.
