Abstract

The invention utilizes the technical field of peony seed seedling culture and uses cultivation, most peony buds of oil peonies are not released from dormancy in planting, the phenomena of leafiness and no flower or flower and no leaf and even no germination often occur, after autumn sowing, radicles develop into roots, epicotyls do not extend and are in a dormant state, and the epicotyls can germinate after a period of low temperature. The method utilizes the technology of peony seed seedling culture, and utilizes the steps of seed selection, seed soaking disinfection, low-temperature storage, sowing and seedling stage management in the culture process, wherein the seed soaking disinfection and low-temperature treatment break the seed dormancy, ensure that the seeds germinate rapidly, accelerate the seed germination, improve the rate of emergence, shorten the time of emergence, and are beneficial to increasing the plant height and the root growth.

Description

Technique for raising seedling by using peony seeds

Technical Field

The invention relates to the technical field of cultivation by utilizing a peony seed seedling raising technology, in particular to a seedling process of peony seeds.

Background

The oil peony belongs to a plant which can be used as both medicine and food, has strong adaptability and drought resistance, and is suitable for being planted in hilly lands. The root bark of peony has analgesic, refreshing, antipyretic, antibacterial and anti-inflammatory effects, and can be used for preventing and treating hypertension and hyperlipemia. At present, most peony buds are not dormant in planting, the phenomena of leafiness and flowlessness or leafiness and even non-germination often occur, after autumn sowing, radicles develop into roots, epicotyls do not extend, the radicles are in a dormant state, and the epicotyls can germinate after a period of low temperature.

Disclosure of Invention

The invention utilizes the technology of peony seed seedling culture, and utilizes the steps of seed selection, seed soaking sterilization, low-temperature storage, sowing and seedling stage management in the culture process, wherein the seed soaking sterilization and the low-temperature treatment break the seed dormancy, ensure that the seeds germinate rapidly, accelerate the seed germination, improve the emergence rate, shorten the emergence time and contribute to increasing the plant height and the root growth.

The technology for raising seedlings by using peony seeds is characterized by comprising the following steps:

a, selecting seeds, namely selecting 8 mature oil in 7-8 months in the lunar calendar, picking and shelling the peony seeds, rinsing with clear water to remove impurities and shrivelled seeds, and drying the plump seeds indoors in the shade;

b, soaking seeds for disinfection, preparing 600 times of potassium permanganate solution, placing the solution into a freezing warehouse for cooling, and soaking the oil peony seeds in the potassium permanganate solution at the temperature of 5 ℃ for 5 hours;

c, storing at low temperature, namely kneading the soaked and disinfected peony seeds by using a towel, storing for 10-20 days at the low temperature of 2-3 ℃, completely reversing once every day, spraying ice water every other day to ensure that the dormancy of the upper shaft of the peony seeds is broken, and obtaining germinated seeds after 20 days;

d, sowing, namely, performing lunar calendar, forming a ridge with the width of 20cm on a sandy soil ground, sowing the peony seeds on the ridge, covering fine soil with the width of 2-3cm, covering dead branches or weeds on the ridge, and culturing seedlings;

and f, managing in a seedling stage, namely mixing 400kg of organic fertilizer per mu, 10kg of calcium superphosphate per mu and 5kg of potassium fertilizer per mu when oil peony flower buds grow to expose bud scales of petioles of the lobules, and topdressing beside the central seedlings of the ridges.

The invention has the beneficial effects that: in the planting process of oil peonies, most of peony buds are not dormant, the phenomena of leafiness and flowlessness, flowlessness and even non-germination often occur, and after autumn sowing, radicles develop into roots, epicotyls do not extend, and the oil peonies are in a dormant state. The method utilizes the technology of peony seed seedling culture, and utilizes the steps of seed selection, seed soaking disinfection, low-temperature storage, sowing and seedling stage management in the culture process, wherein the seed soaking disinfection and low-temperature treatment break the seed dormancy, ensure that the seeds germinate rapidly, accelerate the seed germination, improve the rate of emergence, shorten the time of emergence, and are beneficial to increasing the plant height and the root growth.
