Celery in Ye Mudan is the root flower, and its growth cycle is: growing in winter, flowering in spring and dormancy in summer. The ornamental value of peony with celery leaves depends largely on cultivation and management factors besides varieties. Good quality potted celery leaf peony should be lush, compact and stocky, with dark green and stocky leaves, large and colorful flowers, high double petal rate, and the leaves of flowers should not grow too high in vain.
So what should we pay attention to when raising Qin?
First of all, we should know that Ye Mudan celery can be propagated by sowing or rooting. The sowing propagation coefficient is large, but the seed hybridization rate is high and the seedling variability is also large. It is difficult to ensure the excellent characteristics of the female parent. In order to maintain the characteristics of the female parent, it is necessary to adopt root-splitting propagation.
Ye Mudan enjoys a cool and ventilated environment, so the root tuber is usually planted alone after it is cool in autumn, and it needs a lot of water during its growth. Lack of water in the growth period will lead to short plants, small leaves, less tillers, underdeveloped roots, less flowering, low double petal rate, forced dormancy of plants in the later stage of water shortage, and poor quality of yellow leaves. But as a root flower, too much water is also in danger of root rot. Water supply must also be balanced and appropriate, and excessive drought or water damage will seriously affect growth. The general rule of watering in the growth process is that a certain degree of water is needed at the initial stage of growth, reaching the maximum at the initial stage of bolting, and then gradually decreasing.
Qin is not resistant to high temperature, so it should be placed in a cool, ventilated and well-lit environment. Insufficient light will lead to long white plants, small flowers and dim colors.
Celery in Ye Mudan grows fast, and applying sufficient fertilizer when planting is the key to cultivate strong seedlings. When the planted tuberous roots fully germinate and the leaves spread out, some fertilizers mainly containing nitrogen fertilizer can be topdressing to promote the growth of trees, and buds appear in the center of leaves, and the concentration of paclobutrazol is 100- 120ppm, so as to prevent the ornamental value from being affected by the excessive growth of flower stems.
The use of paclobutrazol is a very important measure for potted celery leaf peony. This is also an important means to ensure the quality of potted flowers in Ye Mudan.
