The price and planting method of peony seedlings

Paeonia lactiflora is a perennial herbaceous flower of Paeonia lactiflora, which is known as "flower immortal" and "flower phase". It can be used as a special garden, cut flower, flower bed flower, etc. The root contains paeoniflorin and benzoin acid for medicinal use, and has the effects of antispasmodic, analgesia and menstruation. Let's take a look at the price and planting method of peony seedlings.

How much is a peony seedling?

The price of Paeonia lactiflora seedlings is about 0.1-0.3 yuan per plant, but the price varies greatly due to the specification, variety, origin and market of the plant. Paeonia lactiflora is light-loving, drought-tolerant and rich in color, such as white, pink, red, purple, yellow, green, black and complex color. the traditional propagation methods are split, sowing, cutting, striping and so on, of which the split method is the most easy to use and is widely used. the sowing method is only used to cultivate new varieties, to produce grafted peony rootstocks and to produce medicinal materials.

Ramet method of Paeonia lactiflora

1. Ramet time: the ramet of Paeonia lactiflora is generally from the end of August to the end of September, when the ramet planting is beneficial to the healing of root wounds and the germination of new roots, enhance the ability of cold and drought tolerance, and lay the foundation for the germination and growth of the following year.

2. Ramet method: carefully dig up the fleshy root during the ramet of Paeonia lactiflora, reduce the root injury as much as possible, remove the persistent soil, cut off the hard and decayed place, and split it with hand or knife along the natural gap, generally, each plant is divided into 3-5 sub-plants.

3. Planting management: the planting depth of Paeonia lactiflora is about 2 cm after planting, too deep is not conducive to germination and easy to cause rotten roots, too shallow is not conducive to flowering and is vulnerable to freezing damage, and even leads to death due to hot summer sun exposure.

Cutting methods of Paeonia lactiflora

1. Cutting substrate: when cutting peony, choose a high-lying and well-drained nursery as a cutting bed, spread 15 cm thick disinfected river sand after the bed soil is loosened, vermiculite or perlite can also be used, and a 1.5-meter sunshade can be built on the bed.

2. Cuttage treatment: the cuttage effect of Paeonia lactiflora was the best in the middle of July. The cuttings were 10-15 cm long, with two nodes, and were quickly dipped in naphthalene acetic acid or indole acetic acid solution with appropriate concentration.

3. Cutting method: the cutting depth of Paeonia lactiflora is about 5 cm, and the spacing is based on the fact that the leaves do not overlap each other, pour water after planting, and then cover the plastic shed, the rooting effect is the best when the substrate temperature is 28 ~ 30 ℃ and humidity is 50%.

4. Management after insertion: peony can take root and form dormant buds 20-30 days after insertion. After rooting, the amount of water spraying and watering should be reduced, and the plastic shed and sunshade should be removed step by step. However, the cuttings grow slowly and need to be covered with soil on the bed to survive the winter, and then moved to the open field for planting in the following spring.

Sowing method of Paeonia lactiflora

1. Seed harvesting: the seeds of peony are not hot too early, and the seed coat blackens and hardens too late to emerge. Do not expose the seeds to harden the seed coat and affect seedling emergence. If you can not sow seeds in time, they can be stored and moisturized, but they must be sowed before rooting.

2. Sowing time: Paeonia lactiflora must be collected and sowed in time in the same year, and the germination rate will be greatly reduced in the next spring, and even if the seedlings emerge, they will die easily because of the underdeveloped root system of the seedlings, which is difficult to resist the drought in spring.

3. Seed treatment: although the seed coat of Paeonia lactiflora is thin, it is easy to absorb water and germinate, but if the seed is treated before sowing, it will germinate more neatly and the germination rate will be greatly improved. The method is to soak the seeds in 50 ℃ warm water for 24 hours and sow immediately after sowing.

4. Soil preparation and fertilization: the peony sowing and seedling land should be fertilized with sufficient base fertilizer, and if the soil is moist and suitable for sowing, you can do border sowing directly. If the soil moisture is poor, you should fully irrigate, and then do border sowing. The width of the border is about 50 cm, and the distance between the borders is 30 cm.

5. Sowing method: peony seeds can be sown on demand, unsown, strip sowing or hole sowing, covered with wet soil after sowing, with a thickness of about 2 cm, sowing about 50 kg per mu and sowing about 100 kg per mu, covered with plastic film after sowing, and removed after sprouting and unearthed the following spring.

Planting methods of Paeonia lactiflora

1. Soil selection: Paeonia lactiflora is suitable for sandy loam with loose and good drainage, but its growth is poor in clay and sandy soil. High soil water content and poor drainage are easy to cause rotting roots. Neutral or slightly acidic soil is suitable, but saline-alkali soil is not suitable for planting.

2. Intermediate ploughing and weeding: after the peony seedlings are unearthed, ploughing and weeding should not be deep in time, so as not to damage the young roots. During summer drought, it should be ploughed to preserve soil moisture, and weeding should be done 3 or 4 times a year.

3. Watering management: Paeonia lactiflora prefers the high and open terrain and relatively dry environment, which does not need regular irrigation, because it is fleshy root, so it is particularly intolerant to waterlogging. Stagnant water for 6 hours and 10 hours often leads to rotting roots.

4. light management: the peony can grow luxuriantly and brightly in the growing period, but it can also grow normally in the light shade, and it can appropriately reduce the temperature and increase the humidity at the flowering stage, so as to avoid the burns of strong sunlight, so as to prolong the viewing period.

5. Temperature management: Paeonia lactiflora is a typical temperate plant, which likes temperature and cold tolerance. It can survive summer safely when the maximum temperature reaches 42.1℃ in summer, and it can still grow and blossom normally when the lowest temperature is-46.5℃ in winter.

6. timely topdressing: peony applied less or no topdressing in the first year, three times a year since the second year, 1000 kg of human and animal manure per mu in late March, 1500 kg of human and animal fertilizer and 15 kg of calcium superphosphate per mu in the middle of April, and 2500 kg of barnyard manure in the middle of October.

7. Picking buds and pruning: except for keeping seeds, peony usually removes its buds during budding to promote the growth of plants and roots. In order to make peony flowers large and beautiful, they should be removed in time after the appearance of lateral buds, so that nutrients can be concentrated on the main buds to achieve the desired goal.
