通过修剪调控露地宿根花卉花期的试验研究

目的]为调控露地宿根花卉的花期探索可行的园艺措施。方法]修剪等简单园艺措施可使部分宿根花卉二次开花，利用这一特点通过修剪试验研究14种宿根花卉的花期调控。结果]在自然花期修剪的植物中，花期调控效果优良的是穗花婆婆纳、大花金鸡菊、宿根福禄考、黑心菊、蓍草、桔梗；一般的是红花钓钟柳、紫花鼠尾草、蒲公英、千屈菜、荆芥；较差的是月见草、‘金娃娃’萱草；飞蓬修剪后不再开花。在自然花期的末花期修剪的植物中，花期调控效果优良的是穗花婆婆纳；一般的是紫花鼠尾草、红花钓钟柳、蒲公英；较差的是月见草。在现蕾期或初花期修剪的植物中，花期调控效果优良的是大花金鸡菊、宿根福禄考、桔梗、黑心菊、蓍草；一般的是千屈菜、荆芥；较差的是‘金娃娃’萱草。结论]简单修剪后，14种宿根花卉中大部分的花期都延长了。

Experimental Research on Regulating the Flowering Stages of Perennial Flowers in Open Field through Trimming

Objective] The purpose of the research was to explore feasible gardening neasures for regulating the flowerng stages of perennial flowers in open field.Method] The simple gardening measures such as trimming could make some perennial flowers bloomed again.Based on this characteristic,the regulation of flowering stages of 14 perennial flowers were researched through trimming experiment.Result] Among the plants trimmed in their natural flowering stages,the plants with good regulation effects on flowering st...
