Through pot experiments, the effects of vermicompost application on the physical and chemical properties of soil and the accumulation of cadmium in rice under flooding irrigation and humid irrigation conditions were studied. The results indicated that the soil pH value under humid irrigation was higher than that under flooding irrigation, and vermicompost accelerated the decline of soil Eh value under flooding irrigation. The content of Fe2+ in the soil under flooding irrigation was significantly higher than that under humid irrigation, and the application of vermicompost further increased the content of Fe2+ in the soil. Compared with the control, the application of vermicompost under flooding irrigation significantly reduced the soil DTPA-Cd content, but it was still higher than the same period of humid irrigation. When the irrigation method is the same, the content of cadmium in brown rice decreases with the increase of the amount of vermicompost. Under the same amount of vermicompost, flooding irrigation is more effective than humid irrigation to reduce the accumulation of cadmium in brown rice.
