| 内容記述 | This study analyzed the possibility of reducing of weeding operations to facilitate the development of a low-cost silviculture system. The study area was located in the Takakuma Experimental Forest of Kagoshima University. The operational time of weeding at a young sugi (Cryptomeria japonica) stand were recordrd during four growing seasons. The stand was divided into five sections, with different weeding schedules used in each section: weeding four times during the 4-year period (every year), three times, or twice (alternate years). The mean heights of the herbaceous and woody coppices and the degrees of visibility of neighbor planted trees in the stand were measured because these values could affect the efficiency of the weeding operation. The following results were obtained: The operational time per hectare of the weeding twice operations were 30-57% shorter than the weeding four times it, on the other hand the weeding three times operation was 20% shorter or 5% longer than the weeding four times it. If the weeding operation frequencies were reduced to half or three fourths, the operational time of weeding didn't reduced by half or three fourths. The reduced weeding schedules caused the herbaceous and woody coppices to grow thickly the following year, which resulted in the need for more weeding the following year. | |||||
