中文摘要 | 本試驗旨在探討栽培密度對臺灣北部地區茭白‘桃園1號’及‘桃園2號’生育與產量之影響。試驗處理包括3種栽培行株距,分別為1m×1m、1.5m×1.5m與2m×2m。結果顯示,2012年及2013年栽培密度對茭白‘桃園1號’及‘桃園2號’株高、每平方公尺有效分蘗數及產量之影響均達顯著性差異,但對筍長、筍徑、剝實率及筍重則均無顯著性影響。在影響茭白產量構成要素中,每平方公尺有效分蘗數與嫩筍產量呈極顯著正相關,但與筍長則呈顯著負相關。故為了獲取較高產量,臺灣北部地區茭白‘桃園1號’及‘桃園2號’之最適栽培密度為1m×1m。 |
英文摘要 | Field experiments were conducted to study the effect of planting density on growth and yield of coba (Zizania latifolia Turcz.) 'Taoyuan No. 1' and 'Taoyuan No. 2' in northern Taiwan. The treatments included three planting densities of 1 m × 1 m, 1.5 m × 1.5 m and 2 m × 2 m, respectively. The results showed that the planting density of coba 'Taoyuan No. 1' and 'Taoyuan No. 2' affected plant height, effective tiller number per m^2 and yield significantly, but not shoot length, shoot width, shoot peeling rate and shoot weight in 2012 and 2013. There was a significant positive correlation between the effective tiller number per m^2 and yield, but a significant negative correlation the shoot length. Planting density of 1 m × 1 m for coba 'Taoyuan No. 1' and 'Taoyuan No. 2' could obtain higher yield. |
