The invention relates to the technical field of slope or slope stabilization, and discloses a slope soil and water conservation pile, system, and method that are obtained locally and can be degraded. After drying, glue is added on site and hot-pressed into soil and water conservation piles for water and soil conservation, which overcomes the problem of difficult material transportation, and the cost is extremely low; the biomass constituting the soil and water conservation piles includes crushed Wood, as well as degradable weeds, straw, leaves, seaweed and other substances; the broken wood is effectively bonded to each other to form a grid-like structure, so that the soil and water conservation piles have a certain strength, broken weeds and other substances Due to poor bonding, a large number of weak points that are easy for mycelia and plant roots to enter are formed on the soil and water conservation piles, so that the soil and water conservation piles can be degraded after the vegetation and fungi on the soil slope grow up, and degrade It can also provide nutrients for vegetation.
