Problems solved by technology

Alpine Rhododendron has early-flowering, medium-flowering and late-flowering varieties, and the technology of heating and lighting is mainly used for flowering of early-flowering varieties; (3) the flowering period cannot be precisely controlled
(4) It is difficult to operate because it cannot be forced to sleep for 2-3 months in an environment of 10°C in various places.
In addition, the difficulty of alpine Rhododendron flower urging is that the buds cannot be colored in a short period of time.

Embodiment 1

[0069] (1) Greenhouse preparation

[0070] On November 20, in the greenhouse that needs to be heated in winter, a new plastic film was used to separate a small space in the greenhouse with a length of 30 meters, a width of 8 meters, and a height of 2.5 meters. The surrounding and top of the small room were sealed with new films. The top of the film is covered with a shading net with a shading rate of 75%.

[0071] Install five 150w high-pressure sodium lamps at a distance of 6 meters on the top of the greenhouse, and install a timer switch.

[0072] A 1.5T bucket is placed inside the partition of the greenhouse. The bucket is equipped with a water pump, a non-transparent watering pipe and a spray gun. The water used is good water with pH 6 and EC 0.6mS / cm or less.

[0073] Place 12 plastic barrels of 30 kg in the greenhouse to hold water, place a hot water bottle in each barrel, and use the hot water to boil water for 24 hours without interruption.

[0074] (2) Treatment of ...

Embodiment 2

[0092] (1) Greenhouse preparation: with embodiment 1.

[0093] (2) Treatment of potted flowers before flower forcing

[0094] 120 pots of alpine rhododendron germinia with a crown width of 60cm and placed in a low-temperature greenhouse at 8°C are placed in a low-temperature greenhouse at 8°C, and the leaves are immediately sprayed with mist water and soil ball watering, and then moved into the prepared blooming in step (1) In the greenhouse, spray 1000 times of chlorothalonil fungicide on the front and back of the leaves.

[0095] (3) Flower-urging technology management when buds germinate

[0096] According to the habits of the alpine rhododendron variety Germinia, it is a very difficult flower-promoting variety because it is difficult to germinate flower buds. In terms of temperature, in the first 4 days after the flower prompting begins, the night temperature is controlled at 18°C, and then controlled at 24°C, the lowest temperature is not lower than 22°C, and the highes...
