摘要:
硒是人体的必需元素,硒缺乏会造成多种疾病。通过摄入农产品适量补充硒,能保证人体健康。对作物补充适量硒肥,是增加农产品硒含量的有效措施。作物吸收硒与土壤因素及肥料因素关系密切,判断哪个因素是影响作物吸收硒最关键的因素值得探讨。通过对文献系统调研发现,影响作物吸收硒的土肥因素中,土壤本身的硒含量及硒肥量最关键,土壤pH及有机质含量为活化土壤硒的间接因素,硒肥种类及施肥方式为配合硒肥量的补充因素。促进作物对硒的吸收要结合土壤性质、硒肥量、施肥方式等因素综合考虑,以达到富硒农产品高产高效的目的。

Abstract:
Selenium (Se) is an essential element in the human body, and Se deficiency can cause many diseases. Replenishing appropriate Se by taking in agricultural products can ensure human health. Fertilize proper Se is an effective measure to increase Se content in agricultural products. The relationship is close between crop Se absorption and the properties of soil and fertilizers. Systematic analysis of the literatures found that soil Se content and the dosage of Se fertilizer are the most critical factors on Se absorption of crops, soil pH and organic matter content are the indirect factors to activate soil Se, and the type and fertilization method of Se fertilizer are the supplementary factors to cooperate with the dosage of Se fertilizer. It is necessary to combine soil property, the dosage and fertilization pattern of selenium fertilizer to promote Se absorption of crops for high yield and high efficiency of Se-rich agricultural products.
Key words:  Selenium fertilizer  Soil properties  Fertilizer rate  Selenium fertilizer types  Fertilization methods
