Abstract: Background With the increase of national investment in infrastructure, a large number of slopes have been generated in the construction process of transportation, water conservancy and other projects. The excavation of the slope destroys the structural plane and plant cover of the slope, resulting in frequent problems such as soil erosion and shallow landslides.And with the concept of ecological civilization deeply rooted in the hearts of the people, people have begun to seek new technologies that can not only ensure the safety of slopes, but also take into account the ecology. Methods In order to comprehensively improve the stability of slope anti-slip and anti-erosion and the ecological effect of slope treatment, this study prepared new fluidized solidified soil with different proportions with new nitrate cement activator + cement as curing agent and local loam as the curing object, analyzed its internal friction angle, cohesion, impact resistance and planting effect through laboratory tests, reasonably determined the construction ratio according to the test results and application objects, and implemented layered spraying for a soil slope in Xiling, Yixian County. Results 1) The Cohesion and Internal friction angle of the fluidized stabilized soil increase along with the augmentation of the hardener dosage and age, while the erosion amount decreases. 2) When the hardener dosage is elevated from two percent to four percent, the outgrowth rate declines by more than 49.89 percent. The cement content is at the level of two percent, the outgrowth rate remains approximately 20 percent. 3) Under the condition that the content of curing agent is less than or equal to two percent, plant growth can significantly improve the impact resistance of solidified soil, and the erosion amount reduces by 22.7 % to 60.9 %. 4) After the engineering treatment, the planting effect on the slope is excellent, and the slope remains stable after the "23.7" heavy rainstorm. Although the planting is affected to a certain extent, the natural recovery effect is satisfactory in the following year. Conclusions The results show that the fluidized solidified soil has good shear and erosion resistance, and the engineering application has also achieved obvious success, which can provide a valuable reference for the theoretical research and engineering application of the application of the slope is treated with fluidzed solidified soil. In order to achieve the goal of enhancing slope stability and reducing soil erosion, so as to achieve the goal of enhancing slope stability and reducing soil erosion.
