Preparation method of pyrolysis oil urea-formaldehyde resin organic covering mat

The invention relates to a preparation method of a pyrolysis oil urea-formaldehyde resin organic covering mat, and belongs to the technical field of landscaping. According to the preparation method, landscaping waste is taken as raw materials, landscaping waste pyrolyzate pyrolysis oil is used for preparing pyrolysis oil urea-formaldehyde resin, and the organic covering mat is prepared by gluing the pyrolysis oil urea-formaldehyde resin and the crushed landscaping waste, so that the shifting and loss problems of a traditional organic mat due to blowing and raining are effectively solved, and the life cycle and the environmental protection effect of the organic covering mat are ensured. Furthermore, the organic covering mat can serve as an effective slow release nitrogenous fertilizer, andthe promoting effect on plant growth is improved; phenols substances are added to the pyrolysis oil urea-formaldehyde resin due to the pyrolysis oil, so that the effect of inhibiting weed seeds from germinating and growing is
