Abstract Soil geochemical background investigation was carried out in the scallion growing area and planned scallion area of Zhangqiu. It is found that the surface soil of these areas has high level of Se, B, P, N, S and low level of F, Mo, CaO. The richness of the beneficial elements, especially Se, constitutes the favorable prerequisite for the development of a Se-rich agricultural base area. Soil fertility status and environmental quality in the region are both good, Se and heavy metal elements values in scallion have a close relationship with their values in soil. A comparison with the green and pollution-free food producing soil standards shows that the survey area land has a high degree of security, which makes the area very suitable for the scallion cultivation. On such a basis, the authors put forward the Se-rich scallion planting plan for Zhangqiu, and the whole work region can be divided into four planning areas: the most suitable area, the comparatively suitable area, the somewhat suitable area and the unsuitable area. The feasibility of developing Zhangqiu Se-rich scallion is discussed in this paper, which may be used as a reference for optimizing the cultivation of Zhangqiu Se-rich scallion and making the plan for further development.
