The present invention relates to a root powder protection cover for protecting the root powder of the excavated tree, and more particularly by protecting the root powder exposed to the outside during the extraction of trees or transplanting trees needed for landscaping work into the inner space of the protective cover Moisturizing the root powder to prevent the drying of the tree, as well as to protect the root powder cover to the root powder in close contact with the root powder relates to a root powder cover that can prevent the loss of soil due to friction between the root powder and the protective cover. That is, the present invention is to form an inner space for introducing the root powder inside, the upper portion, the central portion is composed of an elastic band having an elastic force. At this time, the root powder cover is a biodegradable fiber layer composed of biodegradable fibers to be naturally decomposed in the soil, including the air storage in the lower biodegradable fiber layer, the first and second tissues responsible for rooting roots and smooth breathing It consists of a moisturizing layer to which moisture is absorbed between the layer and the first and second tissue layers to continuously supply moisture to the root powder, and nutrients such as pesticides or root rooting promoters. This prevents the soil sediment of the roots from falling off during transportation and transplantation or planting of excavated trees, and prevents the roots from drying out due to moisture evaporation. will be. In addition, since the environmentally friendly materials that can be naturally decomposed in the ground after transplanting or planting excavated trees are sequentially formed and formed integrally, work efficiency is improved due to the convenience of not removing the protective cover surrounding the root powder. It is effective. In addition, when moisture (water) is supplied to the protective cover surrounding the roots of the tree, the moisture is mo
