The invention relates to an organic rice ecological isolation belt. The phenomena that an organic certification cannot be passed due to the fact that an isolation belt is constructed irregularly and product testing is not qualified due to forbidden matter drifting effects happen occasionally. The isolation belt is characterized by comprising an inner side ridge, a high pole plant planting region, an outer side ridge and side plates. The distance between the inner side ridge and the outer side ridge is 5-8 m, the high pole plant planting region is located between the inner side ridge and the outer side ridge, the inner side ridge and the outer side ridge are each in a trapezoid shape, the upper width of the inner side ridge is 1.0 m, the lower width of the inner side ridge is 1.5 m, and the height of the inner side ridge is 0.35 m, the upper width of the outer side ridge is 0.5 m, the lower width of the outer side ridge is 1.0 m, and the height of the outer side ridge is 0.35 m, the side plates are of a rectangular structure, the side plates are fixed to the inner edges of the inner side ridge, the lower ends of the side plates are lower than the bottom of the inner side ridge, and the upper ends of the side plates are flush with the top of the inner side ridge. Construction is convenient, forbidden matter drifting and leakage can be effectively avoided, and ecological balance can be kept.
