The Living Fossil of Peonies in the World, Qunfang, the Magical Peony Leader of the Han Dynasty

1. Selection of cultivation site:

Peonies are suitable for cold and heat, like dryness and hate dampness, and have deep and long root systems. The cultivation site should be high, open and sunny, well drained, and the soil layer is deep. Sandy loam is more suitable for the soil. There must be a clean irrigation water source, wheat stubble, early corn, and bean stubble plots should be used for field cultivation, and peony should be rotated and heavy cropping should be avoided.

2. Timely cultivation:

Autumn planting: Peonies are suitable for autumn planting, generally from late September to October, so that the root system has a period of recovery before winter and can grow new roots, so as to facilitate the growth of the second year. Too early or too late is not suitable. The root system should be stretched when planting, and the backfill soil should be solid. The root system should be flat with the surface and should not be too shallow or too deep. Water in time after planting.

3. Field management:

Plastic pruning: The purpose of plastic pruning is to make the branches of peony plants evenly distributed, perfect plant shape, ventilated and light-transmitting, reduce the phenomenon of large and small years by regulating the amount of flowers, and prolong the life of the plants.

4. Water and fertilizer management:

(1) Watering: Peony has a well-developed root system, penetrates deep into the soil, and has strong drought resistance. In areas with annual precipitation above 500mm, watering is generally not required for drought. Water only when it is particularly dry. The general times of watering are: ①after spring germination; ②before or after flowering; ③before wintering. Watering in hot weather should be done in the morning and evening, avoid watering in the hot sun. In addition, in the rainy summer season, pay attention to the drainage of the peony nursery, and do not accumulate water.

(2) Apply topdressing fertilizer: Peony is a plant that likes to fertilize. Generally, it can be fertilized three times a year: the first time is after budding in early spring to promote flowering (flower fertilizer); the second time is to promote flower bud differentiation after flowering fades (bud fertilizer) ; The third time is to protect overwintering before winter (winter fertilizer). The first two times were mainly quick-acting fertilizers, and the last time was mainly long-acting fertilizers.

5. Cultivation and weeding:

Cultivation and weeding are generally combined with fertilization and watering. After each watering, the soil should be loosened in time to maintain moisture. Field weeds should be removed in time.

6. Seal the soil for the winter:

Generally, the seedlings of peonies are only sealed with soil to prevent cold in the year of planting, and they can survive the winter safely without sealing the soil in the future.
