When to Pick Peony Seeds (Techniques of Planting Peony Seeds)

First, the feeding method

1, sowing

At the beginning of August, peony seeds were harvested in time after they matured and sowed immediately. If seeds are sown too late, they should not germinate in spring. Peony does not bloom until 5-6 years after sowing, so this method is generally only used when cultivating new varieties.

2. Lamian Noodles

Dig out the big peony plants that have grown for more than five years, put them in the shade for 2-3 days, and when the roots become soft, divide them into small seedlings in groups of 2-3 trees and plant them in the nursery.

3. Transplantation method

Cut off the soil buds or annual short branches of Paeonia suffruticosa, cut them into wedges of 2-3cm, embed them in the roots of Paeonia suffruticosa with a length of 15-20cm, wrap them tightly with hemp skin, spread mud and plant them. Grafting time is 10 from the first ten days of September to the first ten days of 10, and the grafted seedlings should be planted by digging ditches, and the plant spacing should be 10- 15.

Second, the maintenance management

L, fertilization

Fertilize at least three times a year, the first time before flowering, to promote flowering; The second time, it was applied half a month after flowering to supplement the nutrients consumed by flowering; Apply overwintering fertilizer before the third overwintering. The fertilizer is mainly decomposed cake fertilizer. Fertilization amount should be 0.5- 1 kg per plant, or chemical compound fertilizer can be mixed.

water

Peony is drought-tolerant, but it still needs watering in dry season to keep the soil moist, and water should be removed in time after rain.

3, pest control

The common peony disease is brown spot, and the control method is to spray Bordeaux solution or Tobin soaking solution and carbendazim solution every half month after flowering every year. Cut off diseased leaves in time before winter and burn them, and spray sulfur mixture before germination in spring.

The main pests of peony are scale insects. In summer and autumn, white striped worm adheres to branches and leaves, and after winter, it can be sprayed with 500 times fluoroacetamide or 1000 times omethoate liquid or coated with sulfur mixture.

Grubs are the main underground pests, and the control method: wash and water the roots with 50% phoxim EC 1000- 1500 times, and the appropriate amount is 0.25kg per mu.
