玫瑰撚枝栽培技術之研究

為了解玫瑰撚枝栽培法能否提昇切花品質及產量，並比較各種不同撚枝栽培方法進行本研究。試驗係在設施內以高床填充介質作為玫瑰撚枝栽培床並以管路滴噴灌方式供應液肥，採用自走式噴藥裝置防治病蟲害。研究共分成三部份，第一部份為撚枝栽培與傳統修剪之比較，試驗結果撚枝栽培之切花長度明顯長於傳統修剪法，在產量方面亦以撚枝栽培略多於傳統修剪法。在品質比較方面，則以7月份時撚枝栽培之莖較粗花較重外，其餘兩處理間差異不明顯。第二部份為不同撚枝法對切花產量及長度之影響，試驗結果在切花長度方面，‘黛安娜’品種基部收花撚枝法有較長的切花，一、二級品比率之切花也最多，在產量方面以高點收花撚枝法最高。‘金色勳章’品種平均切花長度各處理間差異不顯著。但一、二級品比率以基部收花撚枝法稍高於其他二處理。在產量方面各處理間差異不顯著。在月份比較方面，二品種均以3、4月份產量較高，8、9月份產量較低。第三部份為撚枝栽培法之切花主枝保留不同節數對切花產量及長度之影響，試驗分為留2節、留3節、留4節三種處理，試驗結果‘黛安娜’品種在長度方面，三種處理間差異不顯著，但在一級品方面則以留2節處理之比率最高。產量方面‘黛安娜’品種留4節處理最低。‘金色勳章’品種在產量方面各處理間差異不顯著。一級品比率以留4節者處理最低。

The objective of this experiment was to investigate the effect of different bending culture on the yield and quality of rose. The rose was cultivated in the facility of a raised bench filled with artifical media. The experiment was conducted at Taichung DAIS. The experiment comprise three parts. Which part one were the comparison of bending culture and traditional culture on the yield and quality of rose cut flowers. The result indicated that bending culture had the longer stem and higher yield of cut flower. Part two was the comparison of three different types of bending shoot culture by varying the harvesting position of cut flower. The result showed that higher harvesting position result in shorter stems. On 'Noblesse', cut flowers harvested from shoot base have better quality, while harvested from middle position got higher products. On 'Gold Medal', effect of different harvest position on quality and yield were both no significance, Aug. and Sep. have the lower yield. Part three examined the effect of different renewal shoot nods left on the cut flower yield and quality of bending shoot culture of roses. The result indicated that on 'Noblesse', the renewal shoot of two nodes left showed high-test quality, while on 'Gold Medal', the renewal shoot which cutback from the fourth nodes had the lowest quality.
