Peony flower, also known as peony, is a plant of the genus Paeonia in the family Paeoniaceae, native to China. Peony flowers are rich in color and variety of flower types, and have high ornamental value. The dispersal of peony flowers mainly relies on seed propagation, and the following are the methods by which peony flowers disperse seeds:
Natural dispersal: When the fruit of a peony flower ripens, it naturally dehisves, spreading the seeds into the surrounding environment. These seeds will germinate and grow under the right conditions, forming new plants. Natural propagation is the main way of seed propagation of peony flowers, but it is greatly affected by environmental conditions, and the reproduction rate is slow.
Artificial pollination: In order to improve the reproduction rate of peony flowers, pollination can be achieved by artificial pollination to make pollen fall on the pistil. After pollination, the fruit ripens earlier, which is conducive to the collection and preservation of seeds. Artificial pollination can effectively improve the reproduction rate of peony flowers, but it requires certain skills.
Collect seeds: After the peony flower fruit is ripe, the seeds should be collected in time. The ripe fruit is black or dark brown, the skin is soft, and the seeds are full. When collecting, the fruit can be cut off, placed in a ventilated and dry place to dry, and after the fruit is completely dry, rub the fruit by hand to separate the seeds from the peel. The collected seeds should be stored properly to avoid moisture and mildew.
Sowing: Before planting, you need to prepare fertile, well-drained soil. The collected peony flower seeds are evenly sprinkled on the soil surface and then covered with a thin layer of soil. After sowing, keep the soil moist to facilitate the germination of seeds. In general, peony seeds can germinate about 1-2 months after sowing.
Seedling management: After peony flower seedlings have grown 2-3 true leaves, seedlings can be thinned. Remove the seedlings that are poorly growing and too dense, and keep the seedlings that grow robustly and are evenly distributed. In addition, it is necessary to water and fertilize in time to keep the soil moist and fertile. In the process of peony flower growth, attention should be paid to the prevention and control of pests and diseases to ensure the healthy growth of seedlings.
Transplanting: When peony flower seedlings grow to a certain height, transplanting can be carried out. Choose fertile, well-drained land, dig a pit of the appropriate size, put the seedlings with soil balls into the pit, and then fill and compact it with soil. After transplanting, it is necessary to properly water and fertilize to promote the growth of the plant.
Pruning: During the growth of peony flowers, branches and leaves should be pruned in time to maintain the beauty and healthy growth of the plant. When pruning, be careful not to damage the main trunk and new branches, so as not to affect the growth and flowering of the plant.
Through the above methods, the effective dissemination and propagation of peony flower seeds can be realized. It should be noted that in the process of peony flower propagation, it is necessary to pay attention to grasp the appropriate sowing time, sowing density, fertilizer amount and other technical points to ensure the propagation effect. At the same time, it is also necessary to pay attention to the prevention and control of pests and diseases to ensure the healthy growth of plants.
