| 摘 要： | 研究了春季2～3月不同修剪时间和次数对腾冲过路黄复制开花数、花枝数和枝条直径的影响．认为腾冲过路黄在2月份修剪1次即可，能使其保持更长时间稳定的开花数。如果要使花期延迟些，可再修剪1次．但是花枝直径会明显变小。修剪3次对腾冲过路黄的影响更大．会使开花枝数和开花总数显著减少．花枝直径显著变小。3月底腾冲过路黄开始进入花芽分化期，一般不宜对其进行修剪。

| Abstract: | Pruning is an important technical measure in producing and applying Lysimaehia tengyuehensis. In this paper, the effects of blossom, flower number and branch diameter by different pruning time and the number in spring were studied. As a result, once time pruning in February can keep longer stability of blossom. And twice pruning can delay flowering, but the flower diameter will be significantly smaller. So Lysimachia tengyuehensis can＇t be pruned at the end of March because of it enter the stage of flower bud differentiation. |
