Actual Conditions of Lawn Grass Planted Areas as Ground Cover Plants on Levees

Abstract

As one means of lessening the need for weeding, ground cover plants (GCP) are as a potential way of solving this problem. Among these GCP, we have directed our attention to lawn grass. To grasp the present condition and solve the problems, we carried out an investigation using a questionnaire for areas, where lawn grass has been planted on levees.
The lawn grass was not spread out too densely, but the estimation of lawn grass is high in these planting area. Especially, the characteristic of low height and of bearing ability for trimming and stamping are greatly estimated, and the aptitude of lawn grass for levee's basic GCP could be achieved. However, the merits of lawn grass were not effective enough, and the need for technology development of planting and maintenance must be clarified too. To get steady high estimation of lawn grass as levee's GCP, we have come up with some ideas.
1) Necessity of technical standardization regarding planting and maintenance so on
2) Necessity of having a better appearance by complex planting with other GCP
