摘要
在切花月季上 ,进行了不同部位和不同粗度的修剪试验。结果表明 :在开花天数、花枝长度及粗度方面 ,各处理之间存在差异。综合分析 ,在七叶中部修剪 ,新发枝条的开花天数较短 ,花枝长度和粗度最大 ,是最佳修剪部位。枝条的长度和粗度存在极显著相关关系 (r=0 .96 87) ;只有在直径大于 5 .85 mm以上的枝条上施剪 。
Experiments on the pruning in diffrent positions and with diffrent thickness of rose were conducted.Results show that there is disparity in all treatments such as in days from cutting to flowering, stem length and stem thickness.Synthetical analysis:When the stem of the rose is pruned atcentral section of the seven- leaf,the days from cutting to flowering are shorter,the stem length and stem thickness are greatest,and it is the best section for pruning.There is most remarkable correlation between stem length and stem thickness(Correlation coefficient r=0 .9687) .Only when the thickness of branch is over 5.85 mm and pruning is performed,can the cutflowers with good quality be produced.
