摘要
分别在3月10日、5月20日、7月10日对蓝叶忍冬、榆叶梅、连翘、丁香、黄刺玫、贴梗海棠等6个灌木树种进行修剪试验,结果表明:修剪可促进树体新梢萌发,显著增加枝条数量,且修剪越重,萌发的枝条数量越多;修剪程度对蓝叶忍冬、榆叶梅、连翘、黄刺玫的始花时间、开花天数均没有影响,但对花序的数量影响显著,连翘、榆叶梅、黄刺玫每枝花序数量关系依次为不修剪>轻剪>重剪,蓝叶忍冬每枝花序数量关系依次为重剪>轻剪>不修剪。贴梗海棠不论修剪与否、修剪的重与轻,均不影响开花;而对丁香不论重剪或轻剪处理,次年均不开花,只有不修剪处理才开花。
On March 10,May 20,and July 10,six shrub species of Lonicera korolkowii,Amygdalus triloba,Forsythia suspensa,Syringa oblata,Rosa xanthina&Chaenomeles speciosa were pruned.Result shows that:Pruning can promote the germination of new shoots of the tree and significantly increase the number of branches,and the heavier the pruning,the more branches will germinate.And the degree of pruning has no effect on the flowering time and the number of flowering days of Lonicera korolkowii,Amygdalus triloba,Forsythia suspensa&Rosa xanthina,but has a significant impact on the number of inflorescences,Forsythia suspensa,Amygdalus triloba&Rosa xanthina.The order of quantity relationship is:no pruning>light cut>heavy pruning.The order of the number of inflorescences of each branch of Lonicera japonica is:heavy pruning>light cut>no pruning.No matter whether Chaenomeles speciosa is pruned or not,and the pruning is heavy or light,it will not affect the flowering.For Syringa oblata,no matter it is pruned or lightly pruned,it will not bloom in the next year,and it will only bloom without pruning.
