Embodiment 1

[0028] A plant growth regulator for regulating Phalaenopsis inflorescence types, comprising A agent and B agent: A agent is a water agent, which contains DA-6 with a concentration of 15.0 mg / mL; B agent is absolute ethanol, wherein Contains 6-BA at a concentration of 6.0 mg / mL, NAA at 2.0 mg / mL and KT-30 at 2.0 mg / mL.

[0029] The Phalaenopsis "Naishan Girl" was selected as the test object, and the above-mentioned plant growth regulator was applied during the process of inducing flower buds at low temperature.

[0030] Described plant growth regulator is sprayed 3 times altogether during implementation, and concrete implementation time and method are as follows:

[0031] The first time was carried out at 16:30 on the second day when the flower buds of the Phalaenopsis "Naishan Girl" were induced at low temperature. Add 50ml of agent A and 50ml of agent B to 5L of water in sequence to make a spray solution, mix well, and use a pressure pump Spray 1000 plants;

[0032] The sec...

Embodiment 2

[0038]A plant growth regulator for regulating the inflorescence type of Phalaenopsis, comprising A agent and B agent: A agent 10mL is a water agent, which contains DA-6 with a concentration of 20.0mg / mL; B agent 10mL is absolute ethanol , which contains 6-BA at a concentration of 3.0 mg / mL, NAA at 1.0 mg / mL and KT-30 at 1.0 mg / mL.

[0039] The Phalaenopsis "Red Coral" was selected as the test object, and the above-mentioned plant growth regulator was applied during the process of inducing flower buds at low temperature.

[0040] During the implementation process, it will be sprayed 3 times in total, and it can be managed normally after each spraying. The specific implementation time and method are as follows:

[0041] The first time was carried out at 16:30 on the second day when the flower buds of Phalaenopsis "Red Coral" were induced at low temperature. Add 50ml of agent A and 50ml of agent B to 5L of water in sequence, mix well, and spray 1000 plants with a pressure pump; ...

Embodiment 3

[0049] The method of this embodiment differs from Example 1 in that: the concentration of DA-6 in A agent is 5.0 mg / mL, the concentration of 6-BA in B agent is 2.0 mg / mL, and the concentration of NAA is 0.5 mg / mL. mL, the concentration of KT-30 is 0.2 mg / mL.

Abstract

The invention belongs to the field of crop cultivation technologies, and particularly relates to a plant growth regulator and application thereof for regulating a phalaenopsis inflorescence type. Through applying the plant growth regulator in a process of inducing a bud of the phalaenopsis, the phalaenopsis with a raceme type is induced to be changed to the phalaenopsis with a compound raceme type. The plant growth regulator and the method can be used for different stages of low-temperature bud induction of the phalaenopsis, wider in using range, and have the better adaptability. Proved by a test, after the provided method and plant growth regulator are used, 2-3 dormant buds below a rachis flower of the phalaenopsis are totally germinated as a rachis, and the positive effect of improvingthe blooming quality of the phalaenopsis is achieved. The method is suitable for the industrial cultivation of the phalaenopsis, and the production cost is low. The obtained phalaenopsis is high in quality, good in consistency, has the advantages of low investment and high yield, and has the better popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a plant growth regulator for adjusting the type of Phalaenopsis inflorescences and an application thereof. Background technique [0002] Phalaenopsis( Phalaenopsis aphrodite ) belongs to the Orchidaceae Phalaenopsis genus, is a perennial tropical epiphytic CAM orchid, often used as potted or cut flowers, and is one of the most popular "four ocean orchids" in the international flower market. The flowering time and flowering quality of Phalaenopsis are important factors affecting its commercial value. Phalaenopsis, like most plants, needs a period of vegetative growth before it can accept environmental stimuli and bloom. The flower bud differentiation of Phalaenopsis is mainly regulated by temperature. Mature orchid plants can only produce flower buds after being induced by a certain low temperature (18-25 ℃), and the use of physical and chemical methods can s...
