Hanzhong, a deciduous sub-shrub, originated in the mountainous areas around Qinling Mountain and Daba Mountain in western China, and was the earliest place to cultivate peony artificially in China. Love cool and hate peony.

It likes heat, is suitable for drying and is afraid of humidity, can withstand the low temperature of -30℃, and can grow normally in areas with an annual average relative humidity of about 45%. I like yin, but I'm not very resistant to yang. Loose, fertile and well-drained neutral soil or sandy soil are required, and it is forbidden to stick heavy soil or plant at low temperature. The flowering period is April-May. Grafting is often used for cultivation, because it belongs to Paeonia genus with Paeonia lactiflora, and Paeonia lactiflora is often used as rootstock.

I. Soil

1. Soil quality: Peony is suitable for deep, loose and fertile soil. Soil drainage capacity must be good. Potted plants can be planted in ordinary soil. 2. Soil properties: neutral or neutral slightly alkaline soil.

Second, water.

peony

[2] Proverbs Proverbs say: "Peony should be dry but not wet." Peony is a deep-rooted fleshy root, afraid of long-term water accumulation. Usually it is not advisable to water too much, just dry it properly.

Third, fertilization.

Proverbs Proverbs say: "Clear peony" and "muddy peony". The base fertilizer for cultivating peony must be sufficient. The base fertilizer can be compost, cake fertilizer or manure. Usually it is better to apply fertilizer three times a year, that is, spray fertilizer water containing phosphate fertilizer and Huazhuangdiling once half a month before flowering; Apply compound fertilizer once half a month after flowering; Apply compost once before winter to ensure the next year's flowering.

Fourth, temperature.

Peony is cold-resistant and not high-temperature-resistant. In East China and Central China, you can spend the winter in the open air. When the temperature reaches 4℃, the bud begins to expand gradually. Suitable temperature: 16~20℃, no flowering below 16℃. When the weather is hot in summer, plants are in a semi-dormant state.

Verb (abbreviation for verb) lighting

Proverbs and Peony

[3] As the saying goes, "Yinshan tea, Yangman." Peony likes the sun, but doesn't like the sun. When planting in the field, you should choose a place with higher terrain facing the east and the sun. Potted plants should be placed on the sunny east balcony, such as Nanyang terrace or roof platform, and the west side should be shaded.

Six, cultivation techniques

Luoyang Fan Yu's Works: The only eternal romantic love is Er Qiao.

1. Choose a place with abundant sunshine and no accumulated water, preferably Chaoyang slope, with fertile sandy loam and good drainage. Before planting, dig deep into the ground, the planting pit should be appropriately large, and the peony root should be stretched vertically when it is placed in its hole, and it is not allowed to take root by punching holes. Don't plant too deep, it's best to just bury the roots. Generally, there are fewer potted plants. 2. Sunshine with sufficient light and temperature is beneficial to its growth, but it can't tolerate the scorching sun in summer. When the temperature is higher than 25℃, plants will be dormant. The optimum flowering temperature is 17 -20℃, but it must be treated at low temperature of 1-10℃ for 2 -3 months before flowering. The lowest temperature is -30℃, but appropriate cold-proof measures should be taken in winter in the northern cold area to avoid freezing injury. The high temperature and high humidity weather in the south is extremely unfavorable to the growth of peony. Therefore, in order to enjoy the beauty of peony flowers in the south, we must give specific environmental conditions.

3. Water and fertilize. Water twice before planting. Irrigation 1 time before winter to ensure its safe overwintering. After spring, water should be supplied according to the dry and wet conditions of the soil, but don't water it too much. Generally, fertilizer is applied three times a year, and the first time is 1 time before flowering, and quick-acting fertilizer is applied to promote flowers to bloom well. The second time is fertilization after flowering, topdressing 1 times organic liquid fertilizer. The third time is autumn and winter fertilizer, mainly base fertilizer, to promote the growth of the next spring. In addition, attention should be paid to intertillage weeding, and the soil can be loosened by shallow tillage without leaving weeds. 4. After pruning, pick flowers and prune them in time, combine the desired tree shape according to the natural growth of the tree shape, and at the same time stick a layer of calluses antiseptic film at the pruning mouth to protect the wound and prevent the invasion and infection of germs. If you want plants to be low and have dense flowers, you should cut them short to inhibit branch expansion and tillering. Generally, it is advisable to leave 5-6 branches per plant. 5. flowering control potted peony can bloom in the spring festival by forcing flowers in winter. The method is to select peony varieties with full scales and buds (such as Zhao Fen, Luoyanghong, Shengdanlu, Gejinzi, Zhusha Lei, Dahonghu, Mokui and Wulong Peng Sheng). ) 60 days before the Spring Festival, take it out with soil to minimize damage to the roots, and dry it in the shade 12-3 days before entering the pot. When placing the flowerpot, the size of the flowerpot should match the plant to achieve a satisfactory plant type. After pouring water, it is managed normally. 50-60 days before the Spring Festival, move into a greenhouse around 10℃, and spray water 2-3 times a day to keep it moist. When the scale buds swell, gradually heat them to 25-30℃, and the temperature at night is not lower than 15℃, so that flowers can be seen in the Spring Festival.
