Embodiment 1

[0015] Example 1 (Target flowering time is November 1-29, 2020)

[0016] 1.1 Plant selection and treatment: On June 12, 2020, select alpine Rhododendron potted flowers that grow robustly and are free from diseases and insect pests. At least one of the plants on the alpine rhododendron in the pot is a branch of the current year, and the branch of the current year has at least one tight and full flower bud. deflated. In the present embodiment 1, there are 4-7 branches of the current year on every potted alpine Rhododendron potted flower, and there are 4 to 8 firm and full flower buds on each of the current year's raw branches on each pot of alpine Rhododendron. Spray the whole plant with 1500 times liquid 20% prochloraz aqueous emulsion to moisten all Rhododendron alpine plants, remove new shoots and buds in time during the spraying of the prochloraz, and the day before the low-temperature treatment of the Rhododendron alpine potted flowers Stop spraying the prochloraz, and po...

Embodiment 2

[0020] Example 2 (target flowering time is September 1-27, 2021)

[0021] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0022] 2.1 Plant selection and treatment: On June 1, 2021, there will be 6-9 current-year branches on the selected alpine Rhododendron potted flowers, and each current-year branch will have 6-9 firm and full flower buds, every 7 days Spray 20% prochloraz aqueous emulsion of 1000 times of liquid to the whole plant of every pot of Rhododendron alpine to make all the plants of Rhododendron alpine moist.

[0023] 2.2 Low-temperature treatment for storage: On June 25, 2021, put the alpine rhododendron potted flowers in a cold storage at a temperature of 3°C for refrigeration.

[0024] 2.3 Greenhouse maintenance: The target flowering time of Example 2 is September 1-27, 2021, and 4-6 weeks before the target flowering time, two batches will be arranged on August 4, 2021 and August 16, 202...

Embodiment 3

[0026] Example 3 (target flowering time is October 1-25, 2021)

[0027] Embodiment 3 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0028] 3.1 Plant selection and treatment: On June 1, 2021, there will be 5-9 current-year branches on the selected Alpine Rhododendron potted flowers, and each alpine Rhododendron in each pot will have 5-9 firm and full flower buds on each current-year branch Every 7 days, the whole plant of Rhododendron alpine was sprayed with 20% prochloraz water emulsion of 1200 times of liquid to make all Rhododendron alpine plants moist.

[0029] 3.2 Storage low-temperature treatment: On June 23, 2021, put the alpine Rhododendron potted flowers in a cold storage at a temperature of 4°C for refrigeration treatment.

[0030]3.3 Greenhouse maintenance: The target flowering time is October 1-25, 2021. 4-6 weeks before the target flowering time, it will be stored in two batches on September 3, 2021 a...

Abstract

A low-carbon treatment method for alpine rhododendron potted flowers in autumn in central Yunnan, including selecting alpine rhododendron potted flowers with current-year branches and full buds on the branches in early and mid-June, and treating alpine rhododendrons every 7 to 10 days. Spray fungicides on the whole plant. In late June, place the alpine rhododendron potted flowers in a cold storage at 3-4°C for refrigeration, and put the alpine rhododendron potted flowers in a greenhouse for maintenance. Water, spray 300-400 times liquid amino acid-containing water-soluble fertilizer every 10-12 days, maintain for 4-6 weeks, and the flower buds will open to reach the expected flowering goal. This method enables Rhododendron alpine to bloom in September-November of the same year under the condition of low energy consumption without heating treatment and supplementary light treatment, effectively prolonging the flowering period of Rhododendron alpine and providing more benefits for producers. Provide consumers with more choices.

Description

technical field [0001] The invention relates to the technical field of plant florescence regulation, in particular to the autumn flowering technology of rhododendron alpine potted flowers in central Yunnan. Background technique [0002] Alpine rhododendron, as a high-end and precious flower, especially the New Year's Eve flower, has been shining in China for more than 20 years. Since the natural flowering period of alpine rhododendron is from March to May, in order to realize the flowering of alpine rhododendron during the Lantern Festival and Spring Festival, the Chinese patent application "Method for urging alpine rhododendron to bloom in cold regions" (CN102792847A, 2012.11.28) takes advantage of cold region climate resources, through The comprehensive measures of outdoor low temperature and indoor spraying GA, heating and supplementing light have developed the alpine rhododendron flower-promoting technology in cold regions; "The method of alpine rhododendron winter flowe...
