摘要
钾是植物必需的营养元素,在提高作物产量和改善农产品品质方面起着至关重要的作用,诸多因素会影响土壤钾素的植物有效性,如:黏土矿物类型、土壤温度、水分等。拟在前人研究成果的基础上,从土壤水分角度入手,分析其对土壤钾素固定、释放、运移及钾素评估等方面的影响,总结水钾的互促效应,以便为农业生产提供理论依据。
Potassium is an essential nutrient element of plant and plays a crucial role in yield increase and quality improvement of agricultural products. There are many factors affect soil potassium availability, such as mineral types, soil temperature, moistures and so on. On the basis of previous studies, this paper mainly analyzed the influence of soil moisture on soil potassium fixation and release as well as migration. Coupling effect of soil moisture and potassium are summarized to provide a theoretical basis for agricultural production.
