PROBLEM TO BE SOLVED: To provide a vegetation promoting member which enables plants to grow excellently even in seasons that are harsh for vegetation such as in summer seasons and winter seasons, and to provide a greening method using the same, and a slope greening structure.SOLUTION: The vegetation promoting member 1 has water-absorbing properties, and a thermal conductivity of 0.03 to 0.8, a thickness of 1 to 20 cm, and a flat lower surface S. The vegetation promoting member 1 thus formed is set on target ground so as to make contact with the ground via the lower surface S. If the target ground to which the greening method is applicable, is a slope, the vegetation promoting member 1 is stored in a pocket portion 6 formed in a net 3 laid on the slope, and a vegetative substrate 4b including vegetative seeds, a fertilizer, and a soil improving material, is formed like a vegetative sheet 4 and laid under the net 3, or alternatively sprayed to the net 3 from above.COPYRIGHT: (C)2007,JPO&INPIT【課題】 夏季や冬季など、植生に厳しい時期においても、良好な植物の生育が可能となる植生促進部材と、それを用いた緑化方法及び法面緑化構造を提供する。【解決手段】 吸水性があり、熱伝導率が0.03~0.8、厚みが1~20cmで、下面Sが平面状に形成された植生促進部材1を施工対象地に下面Sが接するように設置する。この緑化方法を適用する施工対象地が法面である場合には、法面上に敷設したネット3のポケット部6に植生促進部材1を収容し、植生種子、肥料、土壌改良材等の植生基材4bは、植生シート4の形にしてネット3の下に重ね合わせるか、ネット3の上から吹き付ける。【選択図】 図1
