Hebao peony, also known as rabbit peony, fish peony, Yingluo peony, broccoli flower (the name is really cute);
Originated in China and Siberia, it is a perennial herbaceous flower with four petals and white stamens extending out of the outer petals, which looks like a pouch shape (Xiaobian feels it is more like a pink turtle). Leaves like peony leaves, so it was named "Lotus peony".
Note: the whole plant is toxic, and eating it by mistake will cause convulsion and other neurological symptoms.
1、 Introduction to daily maintenance
1 basin soil selection
Paeonia suffruticosa can be planted in the field or in a pot. The potted potted plants with deeper depth and better permeability should be selected.
If you use plastic pots and porcelain pots, you can place crushed charcoal blocks or broken hard plastic foam blocks on the bottom of the basin to enhance ventilation and drainage. It grows in loam with more humus. It can be mixed with humus soil and vegetable topsoil in the same amount as culture soil. It grows poorly in sandy soil and clay.
2. Water and fertilizer management
Lotus tree peony is a little drought resistant, and is afraid of water, so it should be watered appropriately. If it is not dry, it should be watered as soon as it is dry. It must be poured thoroughly without ponding. On sunny days during the growth period of spring and autumn and early summer, it should be watered once a day or every other day, and it should be poured once every three to five days in cloudy days. It is good for its growth to keep half of the soil moisture in the basin. In the dormancy period of midsummer and winter, the basin soil should be relatively dry and slightly moist.
It is suitable to add bone meal or decomposed organic fertilizer or NPK compound fertilizer in the culture soil when planting in the pot or changing the soil in the pot. During the growth period of 10 to 15 days, the thin liquid nitrogen, phosphorus and potassium fertilizer should be applied once to make the leaves grow luxuriant and the flowers multiply. Fertilization should be stopped after the flower buds show color, and no fertilizer is applied during the dormancy period.
3 light and temperature
Paeonia suffruticosa originated in Hebei and Northeast China. It likes semi shade environment with sufficient scattered light and is relatively cold resistant. It is afraid of hot summer heat and strong light exposure. It can be placed under the big trees in the courtyard, under the shade frame, or on the shady side of buildings, on the East or north balcony.
Summer dormancy period to be placed in a well ventilated shade, can not see direct light, often to the ground near the water, improve air humidity, reduce temperature.
4 summer and drainage
Avoid prolonged rain, excessive humidity and heat, and encounter long-term hot and humid weather. It will make the leaves withered and rotten.
In midsummer and hot summer, potted Paeonia suffruticosa can be moved to shade under the seedling shed, or buried in the soil to prevent heat stroke and cool down, and maintain good drainage and ventilation. When there is no rain, spray water on the branches and leaves and surrounding areas every day to increase air humidity, so as to ensure the water supply in the peony flower bud differentiation period. In rainy season, pay attention to drainage, and pour down the flowerpot in rainy days to prevent water accumulation in the basin.
2、 Post flowering management
After flowering, 150 times Bordeaux solution or 800-1000 times tobuzin solution were sprayed every 10-15 days to control leaf diseases. Peony root is sweet and easy to be harmed by ants or grubs. It can be killed by 1000 times dichlorvos solution instead of water.
Overwintering pruning
Good ventilation and light transmission, autumn, winter leaves, pruning. Cut the dense branches, such as juxtaposition, cross cutting, introversion and pest control techniques, to keep the plant beautiful shape. At the end of autumn and the beginning of winter, potted she Dan can be buried in the soil, and its branches are exposed to the ground and protected by grass or backwater. (reply: plastic surgery)
Some will directly put the flowerpot into the indoor wintering, the next spring to remove the cover, moved out of the room, placed ventilation to the sun, strengthen the management of fertilizer and water, so that it naturally flowering.
3、 Introduction to reproduction
1 ramet propagation
In February of early spring, when the new buds sprout and the new leaves are not displayed, take the plants out of the pot, shake off the soil at the root, and cut off the tillering tender stems and fibrous roots around the roots with a sharp knife. Two or three plants are planted in one pot and covered with soil two or three centimeters higher than the old soil mark. Water and place the shade. After the new leaves grow, they can blossom in the same year.
Note: the new leaves of old plants are not divided into plants, and they are not divided during the dormancy period in late autumn. They can only be divided once every two or three years, and can not be divided every year.
Cutting propagation
Cut off the inflorescence after the flower withers, cut 10 cm to 15 cm of strong branches with axillary buds in the lower part 7 days to 10 days later, dip the cut with sulfur powder or plant ash, and insert it in the plain soil. After watering, place it in the shade, and spray water to the cuttings. However, the pot soil should be controlled and watered slightly, so that it can take root in the rest of the month, and be planted in pots with soil in the next spring.
3. Sowing and breeding
When the seeds are mature, they are sown as soon as they are picked. However, the seedlings will not bloom until 3 years later. They are not used for family breeding. They are only used for mass propagation or breeding of new hybrid varieties by garden departments.
In autumn, the underground part will be excavated, and the rhizomes will be separated according to the natural section and planted separately. In addition, the rhizome can be cut into sections, each section with a bud, inserted in the sand, after rooting, plant in the basin. Sowing propagation, seedling cultivation 3 years before flowering.
In the growth period to give sufficient fertilizer and water, flowering period less move, in order to avoid falling flowers. After flowering, the aboveground part withers, and the rhizome can be dug up for potted cultivation. The temperature is 15 ℃ and the environment is humid. The flower can be seen again about 70 days.
4、 Pest protection 1 leaf spot
The disease infects leaves, petioles and stems. The lesions were round, then enlarged, and showed irregular large lesions. The lesions changed from reddish brown to black brown, and the central gray brown. The leaf spot pathogen overwinters in the diseased body or along with it to the surface layer, and spreads and infects with wind and rain in the next year.
Treatment: the diseased tissue should be removed in time and burned intensively.
Leaf rust
White Ramping Fumitory
Black brown small round spots appeared on the leaves, and then enlarged or even patches appeared as large irregular plaques, with slightly raised edges and scattered small black spots on both sides of the leaves. Too dense planting, poor ventilation and high humidity are easy to occur.
handle:
Spray medicine at the early stage of the disease to prevent spread.
Commonly used fungicides are carbendazim, tobuzin, mancozen, carbendazim and so on. It is better to use the fungicides alternately in order to prevent the pathogen from producing drug resistance.
