However, although the protective plate is suitable for planting trees, the protective plate may be detached unless it is clearly fixed and fixed around the tree, and the soil around the trees may flow toward the protective plate, Moisture and nutrients were not supplied smoothly, and it was difficult to maintain a good environment for vegetation development.

Disclosure of the Invention The present invention has been made to solve the above problems, and it is an object of the present invention to provide a water-absorbent resin composition which can maintain the moisture required for a tree for a long time by using a material using wood fiber cellulose, Urban, parks, and other complexes that provide a harmony of beauty.

Further, in the present invention, the protective plate in the formation of the protective plate can be partitioned by the inner and outer protective frames around the tree, in the vicinity of the base of the tree where the tree is buried and exposed, And it is possible to block the influx of dust or foreign matter.

It is another object of the present invention to prevent a protective plate from being separated from and detached from the periphery of a tree by engaging a protective plate with a protective frame between the inner and outer protective frames.

Further, according to the present invention, an air layer is formed below a protection plate installed between protective frames, air and nutrients necessary for growing trees are supplied to the roots of the trees through the protection plate, .

In addition, the present invention allows a plurality of drain holes to be formed on the protection plate and is formed so as to form irregularities on the upper surface of the protection plate, so that rainwater or the like can flow smoothly through the protection plate, Also, when stepping on the protection plate, it is possible to contribute to the creation of aesthetics of the city center by the elongated harmony of the square of a road and a park and the like, and to prevent slipping.

The present invention relates to a method for planting a tree in a square such as a road or a park, and in India, comprising the steps of: 80 wt% of wood fiber, 10 wt% of a thermoplastic resin, 4 wt% of a colorant, 2 wt% of a lubricant, In order for the additive to cover the protective plate on which the main raw material is molded, the inner and outer sides of the tree are divided and fixed in a protective frame around the tree, and a protective plate, And air and nutrients necessary for growth of the tree can be supplied to the roots of the tree through the air layer formed under the protection plate.

In addition, on the protective frames of the present invention, a protruding jaw is formed so that the protective plate is kept horizontal with respect to the protective frames, and the air layer is kept wide as it goes from the outside to the inside of the protective frame, So that a large amount of air can be supplied to the vicinity of the trees.
