PROBLEM TO BE SOLVED: To provide an artificial soil molded body molded from artificial soil particles which have a light weight and are easy to handle.SOLUTION: An artificial soil molded body is molded from artificial soil particles 10 such that a plurality of fillers 1 having pores 2 are connected to form a three-dimensional network with communication holes 3 formed between the fillers 1, where the total volume of the communication holes 3 is larger than the total volume of the pores 2. The pores 2 have subnanometer to submicrometer sizes, and the communication holes 3 have submicrometer to submillimeter sizes. The communication holes 3 capture moisture and nutrients from the outside, and the pores 2 are dispersed around the communication holes 3 to permit the pores 2 to receive the nutrients from the communication holes 3.COPYRIGHT: (C)2014,JPO&INPIT【課題】軽量で取り扱い容易な人工土壌粒子を成型してなる人工土壌成型体を提供する。【解決手段】細孔2を有する複数のフィラー1を三次元ネットワーク状に結合することによりフィラー1の間に連通孔3を形成し、連通孔3の全容積が細孔2の全容積より大きくなるように構成された人工土壌粒子10を成型してなり、細孔2はサブnmオーダー乃至サブμmオーダーのサイズを有し、連通孔3はサブμmオーダー乃至サブmmオーダーのサイズを有し、連通孔3が外部から水分及び養分を取り込むとともに、細孔2が連通孔3から養分を受け取り可能なように、細孔2が連通孔3の周囲に分散配置されている人工土壌成型体。【選択図】図4
