Embodiment 1

[0015] A method for regulating the flowering period of peony in winter, comprising the following steps:

[0016] (1) Variety and plant selection: Choose a variety that requires low cooling and is easy to promote flowering, and choose a robust plant that has grown for 3 years. The selected plant has at least 5 branches, and each branch has at least 2 branches. enlarged apical flower buds;

[0017] (2) Forced dormancy: Select the peony plants that need to be controlled for flowering, first put them in an environment of 5°C, and cultivate them at a low temperature for about 1.5 months, then put them in an environment less than 5°C, and cultivate them at a low temperature for 1 month, and then put them Raise the temperature to 10°C and cultivate for about 1.5 months;

[0018] (3) Root promotion: After forced dormancy, water and fertilize the plants during September-October to promote root growth;

[0019] (4) Flower urging treatment: During the flower urging period, the ambient ...

Abstract

The invention discloses a flowering time adjustment and control method for enabling a peony to blossom in winter. The method comprises the steps of variety and plant selection, forced dormancy, root growth promoting and flower forcing treatment, so that a purpose of manually advancing the flowering time of the peony is achieved. The flowering time of the peony is advanced by performing low-temperature treatment on the peony in summer for breaking the dormancy; a purpose of effectively controlling the flowering time is achieved by controlling the temperature and illumination during flower forcing; the treated peony is large and bright-colored; a peony plant is robust; the flowering time is longer; and an ornamental value is high.

Description

technical field [0001] The invention relates to a method for regulating and controlling the flowering period, in particular to a method for promoting flowering of peonies in winter. Background technique [0002] Peony ranks first among the top ten famous flowers in China. It is known as "National Beauty and Heavenly Fragrance" and "King of Flowers". . The flowering period of peonies is generally from April to May, and it was once a luxury for people to let them bloom in winter. However, with the wide application of modern greenhouse technology, it has become a reality for the rich and auspicious peonies to bloom around the Spring Festival. At present, there are many methods to control the flowering period of peony, mainly through temperature control, light control, hormone treatment control and other methods to achieve the goal. Although there are many methods, it is difficult to effectively regulate the flowering period of peonies by using a single treatment method to re...
