Experimental inhibition methods of a lotus community using cutting equipment in a lake

Abstract

The use of cutting equipment in order to inhibit the lotus community in an eutrophic lake was examined. Results of the test indicated that cutting two or three times in a season successfully reduced the number of lotus stems. Of the two methods used, sickle and mechanized cutting equipment, neither method was found to be more successful at eliminating the lotus. Per unit effort, however, cutting lotus by mechanized equipment was 4 times more efficient than using the sickle. Considering this, mechanized equipment was more suited to cutting over a large area. By cutting once in each successive 2 years, the lotus community was eliminated on the third year. As a result of these tests, an effective inhibiting method of a lotus community in a lake was revealed.
