中文摘要 | 坡地在百喜草覆蓋或敷蓋之情況下,土壤 pH 值之空間變異甚大,一般中坡段 pH 值最低,尤以敷蓋區為甚。根據地理統計學之推估,不論有無植生或敷蓋 pH 值變異所影響 範圍均約為 4 公尺,故採樣最佳距離應為 2 公尺,換言之本試驗小區可擴大 4 倍。以 2m × 2m 代替 1m × 1m,如此可節省 3/4人工及費用。 |
英文摘要 | Under covering and mulching of bahia grass on the hillslopes, soil pH values varied markedly. The lowest pH value was found in the mid-sections of the slopes, it is especially true for the plot of the bahia grass mulching. The "a" values (range) of the best correlation was about 4m for all plots, and therefore the best sampling distance would be 2m. The sampling block should be 2m × 2m instead of 1m × 1m. By doing so, we can save three forth of labor and time. |
