GENUSES AND IMPROVEMENT MEASURES OF SECONDARY SALINIZATION OF FACILITY VEGETABLE SOIL
ABSTRACT
This paper explores soil secondary salinization in facility vegetable cultivation and outlines the characteristics, including high intensification and controllability. Soil secondary salinization was defined and the manifestations were described, such as soil changes, increased salinity, and plant growth restriction. Its effects on the ecological environment, including plant growth inhibition, biodiversity destruction and water pollution. The uses are explored, including natural and human factors. Finally, improvement measures such as establishing a drainage system, scientific fertilization, improved irrigation, and artificial light filling are proposed to reduce salt accumulation, restore soil health, and promote sustainable development.
