[0011] Embodiment 1: Regulate the flowering period of potted Rhododendron 'Purple Butterfly'

[0012] Species: Rhododendron variety 'Purple Butterfly' (variety resources are from the National Fruit Tree Germplasm Nanjing Peach Resource Garden). The goal of flowering regulation is to make the 'Purple Butterfly' bloom before the Spring Festival for festival viewing.

[0013] The steps of flowering control are as follows:

[0014] 1) Seedling selection: Choose rhododendron plants with robust growth, no pests and diseases, and full flower buds.

[0015] 2) Colonization: the selected rhododendron plants were colonized in a flowerpot of 30 cm×40 cm, and the cultivation substrate was peat soil: pastoral soil=7:3.

[0016] 3) Release dormancy: On November 5th, put it into a cold storage (temperature 4-6°C), and refrigerate it for 37 days to release flower bud dormancy. On December 12, the rhododendron plants removed from the cold storage were placed in an environment of 18-20°C dur...

Abstract

The invention discloses a method for controlling the flowering period of potted rhododendrons. In November of each year, potted rhododendron plants with full flower buds are selected and refrigerated at 4-6°C for 5-10 weeks to break the dormancy of their flower buds; after the dormancy is broken, the rhododendron plants need to be placed in 10 days of environmental transition at 18-20°C during the day and 8-12°C at night to promote the recovery of the root system from the dormant state to absorb water as soon as possible; Described flower forcing treatment is 10~12 hours of light every day, light intensity 5000~8000lx, 12~14 hours of darkness every day, temperature 22~25 ℃ during light period, temperature 10~14 ℃ during dark period, relative humidity is 50%~70%. The method of the invention can make the potted Rhododendron bloom in January to February (meeting the flower appreciation during New Year's Day and Spring Festival), and the proportion of flowers and leaves is appropriate, and has high ornamental value and commodity value.
