PLANT GROWTH FOUNDATION BED MATERIAL AND ANIMAL DAMAGE PREVENTIVE GREENING METHOD USING GROWTH FOUNDATION BED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an animal damage preventive greening method capable of exerting an effect for preventing the trampling by the intrusion of large animals into a vegetation creation land and direct eating damage. SOLUTION: The natural ground 10 is covered with a foundation bed material added and mixed with soil and/or a carbide at 15% of the whole volume to the compost made of a raw material having a high decomposable sugar content and capable of reducing or preventing an animal attracting effect to create a plant growth foundation bed 11. An animal repellent having a malodorous repellent effect at the volumetric ratio 0.05-0.3% is mixed with the growth foundation bed material or is sprayed on the surface of the foundation bed material, or a plant having a diet repellent effect to bovines and deer as a repellent component is mixed with the growth foundation bed material at 0.2-1% as an auxiliary material. A ground material 12 made of a plant fiber sheet having a corrosion decomposition property and the projection porosity about 10-30% is installed on the whole surface layer of the created plant growth foundation bed, and a net-like protective material 13 capable of suppressing the drop of the plant growth foundation bed due to the trampling of wild animals is stretched. Duckboard-like obstacles 14 are installed in a floated state 10 cm or more on the ground surface on the periphery and in a plant growth foundation bed region created by stretching the protective material 13.
