Embodiment 1

[0025] Choose a mature Cymbidium plant with a plant height of 70-80cm and consistent vegetative growth (the variety is "Hongxia", the flower branch of this variety is upright, and the flower color belongs to the pink flower system) and placed in the center between two titanium alloy electrode plates 2-2 Horizontally placed side by side, the distance between plants is 7cm, and the distance between two titanium alloy electrode plates is 80cm. The environmental conditions for growth in the greenhouse are: light intensity 500-600 μmol m -2 ·s -1 (lighting time 8:00~17:30); temperature 26~30℃ / 19~23℃ (day / night). Adjust the electromagnetic field control box 1 to make it generate a continuous sine wave voltage with a voltage of 0.8kV and a frequency of 3K Hz; treat it for half an hour at intervals of half an hour every day during the day, and treat it 6 times for a total of 3 hours. The time is 8 days earlier than that of the control sample without electromagnetic field treatment. ...

Embodiment 2

[0027] Select a mature Cymbidium plant with a plant height of 80-90cm and consistent vegetative growth (the variety is "Jasper", the flower branches of this variety are drooping, and the flower color is green) and placed in the center between two titanium alloy electrode plates 2-2 and placed side by side horizontally , the distance between plants is 5cm, and the distance between two titanium alloy electrode plates is 100cm. The environmental conditions for growth in the greenhouse are: light intensity 500-600 μmol m -2 ·s -1 (lighting time 8:00~17:30); temperature 26~30℃ / 19~23℃ (day / night). Adjust the electromagnetic field control box 1 to make it generate a continuous sine wave voltage with a voltage of 10kV and a frequency of 30K Hz; contact treatment for 9 hours during the day every day, and continuous treatment for 60 days. The flowering time is 21 days earlier than that of the control sample without electromagnetic field treatment.

Embodiment 3

[0029] Choose a mature Cymbidium plant with a plant height of 90-100cm and consistent vegetative growth (the variety is "Golden Years", the flower branches of this variety are erect, and the flowers are yellow flowers and red lips) and placed in the center between two titanium alloy electrode plates 2-2 Placed side by side horizontally, the distance between plants is 10cm, and the distance between two titanium alloy electrode plates is 110cm. The environmental conditions for growth in the greenhouse are: light intensity 500-600 μmol m -2 ·s -1 (lighting time 8:00~17:30); temperature 26~30℃ / 19~23℃ (day / night). Adjust the electromagnetic field control box 1 to make it generate a continuous sine wave voltage with a voltage of 110kV and a frequency of 100KH; treat it for 5 hours during the day every day, and treat it continuously for 90 days. The flowering time is 15 days earlier than that of the control sample without electromagnetic field treatment.

Abstract

The invention discloses a method for controlling a flowering period of hybrid cymbidium by using an electromagnetic field. The method comprises the following steps of: selecting mature hybrid cymbidium plants with height of 70 to 100 centimeters and consistent nutrient growth; and placing the selected hybrid cymbidium plants in a treatment chamber of an electromagnetic field treatment apparatus, and performing electromagnetic field treatment for 3 to 9 hours continuously or at intervals of 0.5 to 1.3 hours in the daytime and continuously treating for 30 to 90 days to realize advanced flowering period of the hybrid cymbidium, wherein in the electromagnetic field treatment, the voltage of the electromagnetic field is controlled at 0.8 to 110kV, the electromagnetic frequency is 3 to 100kHz, and the waveform is continuous wave or pulse wave. According to the method disclosed by the invention, by the physical method, namely the electromagnetic field, the permeability of cell membranes of the hybrid cymbidium is affected, the metabolism and the photosynthesis of the hybrid cymbidium are quickened, and the flowering period of the hybrid cymbidium is further controlled; and the method is simple in operation, strong in practicability and easy for popularization.

Description

technical field [0001] The invention relates to a method for regulating the flowering period of the cymbidium, in particular to a physical method for regulating the flowering period of the cymbidium by using electromagnetic field treatment. Background technique [0002] Cymbidium (Hybrid Cymbidium ) Also known as Tiger Head Orchid, Simbi Orchid or Cicada Orchid, it belongs to Orchidaceae (Orchidaceae) Cymbidium genus ( Cymbidium ), by Meihualan ( C. insigne ), Jasper ( C. lowianum ) and more than ten kinds of wild original species hybridized. The Cymbidium is tall and beautiful, with large and colorful flowers, and has high ornamental value and economic development prospects. It was introduced into my country in the 1990s and has developed rapidly in recent years. Now, more than 500,000 pots are cultivated and marketed in China every year. However, in my country, the consumption of Cymbidium is mainly concentrated in major festivals such as Spring Festival, National D...
