1. Seed harvesting: peony harvesting too early seeds are not mature, too late seed coat blackened, hardened and not easy to emerge, after harvesting the seeds should not be exposed to the sun to harden the seed coat and affect the emergence of seedlings. If it is not possible to sow seeds in time, it can be treated with sand storage and moisturizing, but it must be sown before rooting.
2. Sowing time: peony must be sown in time when the seeds are collected that year, and the germination rate will be greatly reduced in the spring of the following year, and even if the seedlings emerge, they will be easy to die because the seedling root system is not developed, and it is difficult to resist the drought in spring.
3. Seed treatment: Although the seed coat of peony seeds is thinner and easier to absorb water and germinate, if the seed treatment is carried out before sowing, the germination will be more neat, and the germination rate will be greatly improved, and the method is to soak it in warm water at 50 °C for 24 hours, and then sow it after taking it out.
4. Soil preparation and fertilization: peony sowing seedling land should be applied with foot fertilizer, deep leveling if the soil is more moist and suitable for sowing, can be directly used for furrow sowing, if the moisture is poor, should be fully irrigated, and then furrow sowing, furrow width of about 50 cm, furrow spacing of about 30 cm.
5. Sowing method: peony seeds can be sown, sown, sown or sown, covered with wet soil after sowing, with a thickness of about 2 cm, about 50 kg per mu, about 100 kg of sowing, covered with mulch film after sowing, and removed after germination in the spring of the following year.
