Problems solved by technology

However, most of the current flower control technologies use a single plant growth regulator. Although some plants have been successful, for most plants, a single plant growth regulator is difficult to obtain satisfactory results.
As utilizing 100 mg / liter 6-benzylpurine to induce Dendrobium to bloom, though it can advance the flowering period, it can't completely get rid of the low temperature, and it also causes adverse consequences such as shortening the flowering period (Shao Limei, Meng Xiaoxiong, Plant Growth Regulator Application Manual, Jindun Publishing House , 1999, p73)

example 1

[0017] Take 60 pots of Dendrobium dendrobium potted plants that are in good growth state and have fully expanded pseudobulb leaves, and each pot has 3-5 pseudobulbs. There were treatment and control groups, 30 pots in each group. The treatment group was after the leaves of the pseudobulbs were fully expanded. First spray the foliage with a mixed solution containing 3 mg / L paclobutrazol and 5 mg / L abscisic acid, and then spray the foliage with 20 mg / L thiadidiazol solution after 10 days; the control sprays water. The amount of spraying is subject to the water droplets dripping from the leaves. Put it in a greenhouse with a daily temperature of 28-30°C and a night temperature of 22-25°C, and water it once a week. After 30 days, the treatment generally formed flower buds, and the induction rate reached 100%, while no flower buds formed in the control, and the induction rate was 0%.

Embodiment 2

[0019] Take 60 pots of Dendrobium dendrobium potted plants that are in good growth state and have fully expanded pseudobulb leaves, and each pot has 3-5 pseudobulbs. There were treatment and control groups, 30 pots in each group. The treatment group was after the leaves of the pseudobulbs were fully expanded. First spray the foliage with a mixed solution containing 5 mg / L of paclobutrazol and 7 mg / L of abscisic acid, and then spray the foliage with 15 mg / L of thiadidiazol solution after 10 days; the control sprayed with water. The amount of spraying is subject to the water droplets dripping from the leaves. Put it in a greenhouse with a daily temperature of 28-30°C and a night temperature of 22-25°C, and water it once a week. After 30 days, flower buds were generally formed in the treatments, and the induction rate reached 95%, while no flower buds were formed in the control group, and the induction rate was 0%.

Embodiment 3

[0021] Take 60 pots of Dendrobium dendrobium potted plants that are in good growth state and have fully expanded pseudobulb leaves, and each pot has 3-5 pseudobulbs. There were treatment and control groups, 30 pots in each group. The treatment group was after the leaves of the pseudobulbs were fully expanded. First spray the foliage with a mixed solution containing 2 mg / L of paclobutrazol and 10 mg / L of abscisic acid, and then spray the foliage with 25 mg / L of thiadidiazol solution after 10 days; the control sprayed with water. The amount of spraying is subject to the water droplets dripping from the leaves. Put it in a greenhouse with a daily temperature of 28-30°C and a night temperature of 22-25°C, and water it once a week. After 30 days, flower buds were generally formed in the treatments, and the induction rate reached 98%, while no flower buds were formed in the control group, and the induction rate was 0%.

Abstract

A method for regulating the blossoming period of spring dendrobium nobile featues that after the blades of its pseudobulb are fully developed, the mixed solution containing paclobutrazol and abscisic acid is sprayed onto the surface of blades for promoting the pseudobulb to become rope, and after 10-15 days, the solution containing thidiazuron is sprayed on the surface of its leaf for inducing the generation of flower buds.

Description

technical field [0001] The invention relates to a method for regulating the flowering period of Dendrobium dendrobii, in particular to a method for controlling the flowering period of Dendrobium springii by using a plant growth regulator. Background technique [0002] Flowering regulation refers to the method of artificially controlling the flowering time of flowers. [0003] Dendrobium dendrobium is one of the most ornamental orchid species in the world and is generally popular. Dendrobium is native to tropical and subtropical regions, mainly distributed in Asia and Oceania. The cultivation of Dendrobium dendrobium needs warm and humid climate conditions, and its flowering induction requires a relatively low temperature condition, so the flowering period is from March to May. Artificial low-temperature treatment, that is, the daily temperature is 15-20°C, and the night temperature is 10-15°C, and the time is 30-40 days (Huang Dinghua, New Technolog...
