A kind of cultivation method of peony using natural low temperature to promote spring festival

Abstract

The invention discloses a natural low temperature enclosure cold storage method applied to forcing culture of peony potted flowers during the Spring Festival. After outdoor temperature descends to be below 0 DEG C at night, the peony potted flowers are tightly placed, matrix bags containing peat are arranged round the peony potted flowers to be piled up and are 50-70 cm high and 35 cm wide, the upper portions of the matrix bags containing peat are covered with matrix bags containing pine needles, the matrix bags containing pine needles are 20-30 cm thick, and accordingly the protected internal environment can maintain a stable temperature. When the external temperature rangeability ranges from minus 15 DEG C to 10 DEG C, the temperature of environment in which the enclosed Chinese herbaceous peonies are is stabilized in a range of minus 4 DEG C and 2 DEG C, and cold storage time lasts for 4-7 weeks. The method solves the problems that in forcing culture, open-air natural low temperature meets the requirements that needed cooling capacity time is long, the gibberellins concentration is difficult to control in processing, and product quality is unstable, and when a refrigeration storage is used for cold storage, the limit of the refrigeration storage area on the flower forcing scale is high, cost is high and much energy is consumed, the situation that the peony potted flowers bloom during the Spring Festival is realized under the circumstance that energy is saved, the flowering phase is advanced by 80-90 days than a natural flowering phase, the yield reaches 90%, and growth and bloom are superior to those of conventional field cultivation.

Description

technical field [0001] The invention belongs to the field of flower potted flower production technology and florescence regulation technology, and relates to the production method of peony spring festival substrate cultivation industrialized potted flower, specifically related to preliminary preparation (seedling stock, substrate, field), potting, root cultivation, outdoor artificial low-temperature refrigeration, greenhouse cultivation, etc. step. Background technique [0002] Peony ( Paeonial actiflora Pall . ) is a famous traditional Chinese flower with profound historical and cultural connotations and national characteristics. It has rich colors, huge flowers, various flower shapes, and simple cultivation and management, and is deeply loved by the people. 'Liantai' is a traditional fine variety of peony, with pink flowers and straight flower stems, implying auspiciousness. It is very suitable as potted flowers or cut flowers, and is very suitable for product promotion....

AI Technical Summary

Problems solved by technology

Among them, natural low-temperature refrigeration requires a long time to achieve cooling, and the flowering period can only be more than one month earlier than the natural flowering period, which cannot achieve flower supply during the Spring Festival; gibberellin treatment can achieve flowering during the Spring Festival, but the use of gibberellin is easy to destroy the hormone balance of peonies , the concentration is not easy to control, and it is easy to lead to problems such as poor flower quality and abortion, which is not conducive to standardized production; the method of low-temperature storage in cold storage can realize the flowering of peony in Spring Festival, and the flowering quality is also good, but it consumes a lot of energy and costs. There is a limit to the scale of flower urging. When the research results are applied to actual production, it is found that using cold storage to break dormancy for flower urging can reach a price acceptable to consumers, and the profit margin of the producer is not high.
