INTRODUCTION OF LOW-HEIGHT GRASS SPECIES TO MAINTAIN THE FUNCTION OF LEVEE VEGETATION EFFICIENTLY

Abstract

Due to decrease of maintenance budget, the annual times of weeding have been reduced. As the result, transition of vegetation to adventive plant with weak root and high height has happened. It causes many problems such as reduction of erosion resistance, inhibition of monitoring of levee etc.

Based on this backdrop, experiment was conducted to introduce measures to keep necessary function and reduce cost of weeding on levee vegetation.

Focusing on height restraint of vegetation, this report summaries the finding of our experiment to introduce “low-height grass species” and “spraying of specific herbicide”.
