Breeding and Protection of Heze International Peony Fair

It usually propagates by branching and grafting, but it also propagates by sowing and cutting. The suitable period of transplantation is from late September of 10 to early October of 10, neither too early nor too late. If you like fertilizer, you should fertilize it at least three times a year, namely "flower fertilizer", "bud fertilizer" and "winter fertilizer". Pruning should be carried out after 2-3 years of cultivation. For varieties with vigorous growth and strong branching ability, it is only necessary to cut off the weak branches, keep all the strong branches, and remove the new buds at the base in time to maintain a beautiful plant shape. Bud removal is also an extremely important job. In order to make plants produce bright flowers and keep plants strong, the number of flowers should be controlled according to the age of trees. In the early stage of budding, a certain number of fully developed flower buds should be selected, and excessive flower buds and weak buds should be removed as soon as possible. Generally, 5-6 year-old plants keep 3-5 flower buds. For newly planted plants, all buds should be removed in the spring of the following year to prevent flowering, so as to concentrate nutrition and promote plant development. Peony is a deciduous shrub with deep roots. It likes sunshine, cold resistance, cool environment and avoids high temperature and sultry. It is suitable for children to grow in loose, fertile and well-drained sand. Therefore, it is appropriate to use the mixed soil of sand and cake fertilizer as the pot soil for cultivating peony flowers, or to mix it with fully decomposed manure, garden soil and coarse sand at the ratio of1:1. If the cultivated soil contains too much water, its fleshy roots will rot easily. Therefore, when it rains continuously, it must be drained in time, and never let water accumulate in the roots. Peony is not resistant to high temperature, so it needs to take timely cooling measures in hot summer. It's better to build a gazebo to give it shade. Cover with straw curtains or reeds before noon and remove them at night. This measure, if implemented in time, can prevent defoliation. If it is left to heat the fallen leaves, it will seriously affect the future flowering. Peony has long roots and large plants, which is suitable for ground planting. If you want to plant a pot, you should choose a large, permeable soil basin with a depth of more than 30 cm. It is best to use a crock 60-70 cm deep. The propagation of peony flowers can be accomplished by sowing, branching and grafting. Peony has always been the most valued flower king in China, equivalent to the queen of flowers in the eyes of Europeans-rose. Zhou Dunyi's "Love Lotus": "Since Tang Li came, the world loves peony." Ouyang Xiu, a writer in the Song Dynasty, wrote peony stories. Later, many people specially revised the peony spectrum and recorded various varieties.

Peony was designated as the national flower in the Qing Dynasty, and the national flower was changed to plum blossom in the Republic of China because it established its capital in the south. People's Republic of China (PRC) has no national flower. The city flower of Luoyang and Heze is peony. 1in the middle of 990, People's Republic of China (PRC) (PRC) National Flower Association held a national flower selection, and the conclusion was that peony was the national flower, with orchids, lotus flowers, chrysanthemums and plum blossoms as auxiliary four-season flowers. However, this conclusion only stopped at the announcement of the association and did not enter any legislative procedure. Therefore, People's Republic of China (PRC) still has no official national flower. In March, 2007, 62 academicians from China Academy of Sciences and China Academy of Engineering signed a joint name, hoping to identify Plum Blossom and Peony as the dual national flowers of China at the National People's Congress in March, but in the end they failed.

Because peonies bloom in the most sleepy period of the year, Japanese people paint peonies in shrines to commemorate the famous dead to ensure their good sleep. Similar to the occasions when people in China use lotus patterns. Japanese writer Yukio Mishima once wrote a short story "Peony", which tells the story of a peony planted by a Japanese general who slaughtered China in World War II.

Peony represents luxury in the eyes of Europeans, and it is becoming more and more popular to cultivate peony at present. There is also a saying in China Zhou Dunyi's "Love Lotus": "Peony blossoms are rich." .

The peony in "the peony dies, the ghost is romantic" is a metaphor for a beautiful and moving woman, and it is also an affair of sacrificing life for a beautiful woman. From Liu E's Travels of Lao Can in Qing Dynasty. The second edition for the third time: "Ren personally said to me yesterday:' I really love you, I love you very much. If I can achieve good things for both of us, I will be ruined, I am willing; I'm dead, so am I. The ancients said well: peony flowers die, and ghosts are also romantic. "I just want to know if you have me in your heart." "
