A kind of method for growing seedlings of peony seeds for oil

Abstract

The invention discloses a seedling raising method for oil-used peony seeds. The method comprises the steps of (1) selecting seeds; (2) soaking the seeds for disinfecting; (3) treating the oil-used peony seeds of step (2) by using cold plasma generated by atmospheric dielectric barrier discharge for 50-60 seconds; (4) preparing a treatment solution containing 0.25mg / L of gibberellin, 2mg / L of indoleacetic acid and 3mg / L of calcium chloride; (5) performing variable temperature stratification: mixing the oil-used peony seeds treated in step (3) with fine sand, perlite and vermiculite in a ratio of 1:(3-5):(1-2):(1-2), adjusting the humidity to 40-50%, and performing variable temperature stratification in a constant temperature incubator according to three stages; (6) sowing; and (7) performing seedling management. By adopting the seedling raising method for the oil-used peony seeds, seed dormancy can be effectively broken during breeding, so that seeds are quickly germinated, germination of seeds is accelerated, the emergence rate of seeds is improved, the emergence time is shortened, the emergence is even, and the growth indexes of young seedlings such as fresh weight, plant height, root system and the like are improved to different degrees; and the method does not have pollution to the environment.

Description

technical field

[0001] The invention relates to the technical field of seedling cultivation of flowers, in particular to a method for seedling cultivation of peony seeds for oil. Background technique

[0002] Peony for oil is a kind of national flower peony. It is not only a woody oil plant but also a plant with medicinal value. It is also a green tree species with high ornamental value. It has strong adaptability and drought resistance. Growing in the Jiangbei Plain in Anhui, it is an excellent tree species for implementing land efficiency enhancement, greening the countryside, and improving ecological conditions. The root bark of peony for oil has medicinal functions such as analgesia, cooling and antipyretic, antibacterial and anti-inflammatory, and immunity. It is also known as the four famous medicines in Anhui along with white peony root, chrysanthemum, and poria cocos, and it is also one of the 34 famous medicinal materials in the country. Peony seed oil has a certai...

[0022] A method for raising seedlings of peony seeds for oil, comprising the following steps:

[0023] (1) Seed selection: select mature, disease-free peony seeds for oil, use clear water flotation to remove impurities and shriveled seeds, and select healthy peony seeds for oil. The purity of peony seeds for oil is 100%, and the seed vigor is more than 95%. ;

[0024] (2) Seed soaking and disinfection: the oily peony seeds of step (1) were placed in 40 DEG C of water to soak for 24 hours, then took out and dried the seed surface moisture, then sterilized with 10% sodium hypochlorite for 10 minutes, rinsed with sterile water 5 times, Dry the surface moisture of the seeds in the shade for later use;

[0025] (3) Utilize the cold plasma treatment step (2) that the atmospheric pressure dielectric barrier discharge generates oil peony seeds, the time of plasma treatment seed is 50s; The power supply of described dielectric barrier discharge is a high-frequency high-voltage power s...
