PLANT GROWTH BASE MATERIAL, SOIL BASED ON USE OF THE SAME, GREEN AREA BASED ON USE OF THE SAME, AND GREENING METHOD BASED ON USE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for avoiding deterioration of water retention caused by weight saving and thin layer formation with a plant growth base material especially when the material is used for a roof floor, while it is demanded to avoid effusion of soil components caused, for example, by strong wind and/or heavy rain in the greening of the roof floor and a wall surface.;SOLUTION: A polymer that has a reactive silicon group, an inorganic substance that has a porous structure, and a plant growth base material that contains water are used. Thus, the effusion of soil components is not only avoided, but the transpiration force is also suppressed for soil and plant to enhance the water holding capacity. Additionally, it is possible to retard the extent of dryness in a thin layer as well, and it is possible to realize labor saving for watering management.;COPYRIGHT: (C)2015,JPO&INPIT
