Problems solved by technology

Therefore, the promotion of cultivation during the Spring Festival requires a series of operating procedures such as potting, root cultivation, storage in cold storage, storage, and storage in the greenhouse. However, storage of peonies in storage for refrigeration consumes a lot of energy, the process is cumbersome, and wastes manpower and material costs; it is not stored outside for wintering. , into the greenhouse at the beginning of December for flowering during the Spring Festival, the cold accumulation in the south of the Yellow River is insufficient, and the flowering is not good
The flower-pressing procedure is cumbersome and the cost is high, which to a certain extent limits the market promotion of peony new year flower products

Embodiment 1

[0037] A method for breaking dormancy of peony buds, comprising the following steps:

[0038] On September 28, 2017, the roots of the 3-year-old peony (variety: Dafugui) were trimmed, soaked in 800-fold diluted carbendazim for sterilization, sprayed with 1000-fold diluted ABT rooting powder solution, and placed in pots. The substrate was peat: Vermiculite: perlite: decomposed chicken manure, the volume ratio is 6:2:2:1, and the pot is a plastic pot with an inner diameter of 30 cm and a height of 25 cm.

[0039] 1) Put the above-mentioned potted peony in the pot to raise the roots until October 16, check the root system until the new root grows to about 2cm, and pour 200mg / L GA into the peony pot once every 3 days 3 , watering 150ml each time, watering 3 times in total;

[0040] 2) After watering, place the flower pot outdoors in a leeward and sunny place, and the peonies will start to germinate one week later. From potting to before entering the greenhouse, depending on the ...

Abstract

The invention relates to a method for breaking peony bud dormancy and belongs to the technical field of plant cultivation. The method comprises the following steps: 1) after putting peony in a pot androots are raised, pouring GA3 into a peony pot; 2) putting the potted peony at the leeward and sunny position after pouring the GA3, and keeping warm for the potted peony when the lowest air temperature is reduced to 2 to 4 DEG C; 3) when the daily minimum air temperature is less than -2 DEG C, immigrating the potted peony into an unheating greenhouse, starting to heat in the middle of December,increasing the room temperature to 10 to 20 DEG C after stem leaves grow, controlling the temperature to 15 to 25 DEG C in the bud growing state and later, heating the greenhouse every day and supplementing light simultaneously. A series of special operation processes of entering a storage to refrigerate, going out of the storage and entering the greenhouse are not needed by utilizing gibberellinsand a natural low-temperature method, the process of breaking the peony bud dormancy is greatly simplified, and the cost is reduced; meanwhile, compared with the traditional refrigeration storage refrigeration method, the method has the advantage of leading the flowering phase of the peony 15 to 20 days in advance.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cultivation method suitable for main planting areas of peony, such as Shandong and Henan, and using gibberellin plus natural low temperature to break the dormancy of peony without low-temperature refrigeration. Background technique [0002] Peony symbolizes wealth and auspiciousness. It has been cultivated as an outdoor ornamental flower for two thousand years and is deeply loved by the people of our country. Peony is a perennial herb that can bloom continuously for many years once cultivated. Its ornamental value is high, and flowers, stems, and buds can all be admired.
