摘要
Abstract
Taking eastern area of Wulian county in Shandong province as the study area,through collecting wheat,corn and root soil samples systematically,analysis and testing of beneficial and harmful elements have been carried out in order to identify the migration and enrichment rules of selenium elements in soil-crop system in the study area and their influencing factors.It is showed that main source of elements in crops is soil.The accumulation capacity of different parts of representative crops for selenium is different.It will follow the characteristics of root system>leaf>stem>seed.The selenium elements in the seeds of crops are positively correlated with the selenium elements in the soil.The correlation coefficient of Se ele-ment between the wheat seeds and the root soil is 0.57,while it is 0.32 between corn seeds and root soil.It is indicated that the accumulation capacity of Se in wheat seeds is stronger than that in corn seeds.Absorp-tion of Se by crops is not only related to total amount of Se,but also to the form of Se,such as water-sol-uble Se such aselenate,which is the easiest to be absorbed by plants.In addition,it is also related to or-ganic matter,pH,and is affected by heavy metal elements parent rock of soil formation,and other soil physicochemical properties.Its research results have important guiding significance for the construction of high standard farmland,scientific nutrition fertil,environmental quality evaluation.关键词
