Abstract
本試驗以中莖種藺草Fs-72-p-8006 與細莖種藺草岡山3 號為材料，探討插值後180、195、210與225日等四種收穫期對藺草產量與品質的影響，藉供栽培之參考。不同生育階段之調查顯示，藺草株高之增長速率以插植後120~150日問最高，90~120日問次之，180日後之生長已趨緩漫，二品種之表現相似。分蘗之增加亦以插植後90~150日間最為迅速，細莖種岡山3號之分蘗數顯著高於中莖種FS-72-P-8006。二品種之乾草產量及株高均以210日處理最高，中莖種之產量為13,580 kg / ha，有效莖長127.5 cm，細莖種之產量為11,510 kg / ha，莖長118.0 cm，均優於其他收穫期處理。藺草之髓徑與莖徑呈密切正相關，且無處理間差異，中莖種之平均莖徑為1.49 mm，髓徑為1.41 mm，細莖種則分別為1.06 與1.00 mm。品種間比較，中莖種FS-72-P-8006 之產量，品質及其他農藝性狀表現均較佳。試驗結果顯示，就產量與草長分級而言，中莖種FS-72-P-8006 之收擭期以插植後210日，細莖種岡山3號則以225日最為適宜。
A medium-stem line Fs-72-P-8006 and a slim-stem variety Kangshan No. 3 were tested in this experiment to seek a harvest date for high yield and good grass quality of mat rush grown in Taiwan. The above-ground portion of plants was harvested 180, 195, 210 and 225 days after planting and some important agronomic characters were investigated.
Experimental results showed that mat rush harvested at 210 days after planting produced the highest dry straw yield, plant height, tiller number and stem diameter among the four treatments for either variety. The yield of Fs-72-P-8006 and Kangshan No. 3 after 210-day growth was, respectively, 13,580 and 11,510 kg/ha. Corresponding values of plant height and stem diameter for the two varieties were 127.5 cm vs. 118.0 cm and 1.49 mm vs. 1.06 mm, respectively. The medium-stem Fs-72-P-8006 performed better than the slim-stem variety Kangshan No. 3.
No significant difference in pith diameter was found in relation of various growth durations. Average pith diameter was 1.41 mm for Fs-72-P-8006 and 1.00 mm for Kangshan No. 3. The former was significantly thicker than the latter.
In conclusion, a growth period of 210 to 225 days was recommended for growing mat rush in Taiwan. A shortened growth would cause lower dry straw yield and inferior grass springness and hence would lower the economic value of the crop.
