The present invention relates to an afforestation structure installed on a cutting area of a slope requiring afforestation, which uses a water absorbent resin to allow soil to retain more water to allow plants to use the water to grow. According to the present invention, the water absorbent resin absorbs and stores supplied water and then slowly drains the water to continuously supply water to plants. Since air gaps are formed between absorption and drain pipes and vegetation soil by expansion and contraction of a volume by absorption and drainage of the water absorbent resin or soil density of vegetation soil around absorption/drain pipes is lowered to improve air permeability of soil, an environment suitable for growth of plants can be maintained. Also, since the water absorbent resin is accommodated in a felt container to prevent a loss thereof, a drain passage is not blocked by the water absorbent resin, and absorption and drain pipes act as the drain passage in vegetation soil to prevent ...
