Abstract: In consideration of the low elevation and high under groundwater level in Honghu county, the agricultural and ecological benefits of lowland-upland rotation were discussed from the oxidation-reduction theory. The rotation years of water-dry shift for cotton cultivation were suggested at 6-7 years and dry-water shift for rice cultivation at 4 years, which might facilitate the fuller circling of soil nutrients and the continuous increasement of yield productions. Conditions for the optimum ecological benefits were also discussed.
