摘要：The runoff and sediment characteristics during different growth periods in peanut were explored to provide a theoreticalbasis for improving the soil ero-sion of land cultivated with peanut. The runoff and sand production of slopes cultivated with peanuts were evaluated using artificial rainfall simulation tests in the field with three rainfall intensities(60,90, and 120 mm/h) during four peanut growth periods (bare land stage, seeding stage, bearing pod stage, and pot mature stage). The results indicated that the bare land stage was the most prone to runoff and ex-hibited the most severe surface soil loss, whereas the bearing pod stage and pot mature stage demonstrated the best water storage and soil conservation benefits. The sediment reduction benefit of peanuts is better than the runoff reduction benefit. Rainstorms will weaken the soil and water storage capacity of pea-nuts.
