Rhododendron lapponicum flower forcing method in cold regions

Abstract

The invention relates to a rhododendron lapponicum flower forcing method in cold regions. The method comprises the following steps of: carrying out low-temperature dormancy treatment on potted rhododendron lapponicum outdoors by utilizing climatic resources in cold regions; carrying out indoor greenhouse space arrangement; breaking dormant flower forcing management, removing lateral buds and spraying 1000ppm of exogenous hormone GA3 to germinating buds; carrying out heating, filling light to regulate room temperature, humidity and illumination in the greenhouse and carrying out water and fertilizer management; and managing the temperature, humidity and water and fertilizer after the buds have colors. The method has the following beneficial effects: by utilizing the peculiar climatic resource advantages in the cold regions to carry out low-temperature dormancy treatment on rhododendron lapponicum outdoors and using variable temperature light filling indoors in combination with the exogenous hormone, the aims of shortening the rhododendron lapponicum flower forcing time in the cold regions and reducing the production cost are achieved; the key problem of rhododendron lapponicum flower forcing in the cold regions is solved; and the technology caters to the lunar new year flower market demands and provides technical support for industrial production of potted flowers in the Heilongjiang province.

Description

technical field [0001] The invention relates to a method for urging alpine rhododendrons to bloom in cold regions. Background technique [0002] Alpine Rhododendron is widely favored by Europeans because of its beautiful flower posture, bright colors and charming charm. It is a high-end and precious flower in European countries, and it has become the new darling of the flower market in China. Its natural flowering period is from March to May. If you want to make it bloom in the new year, you must first choose a variety with an earlier flowering period, and have a sufficient number of well-developed flower buds and a plant type with good ornamental properties. Then carry out low temperature dormancy treatment for 2 to 3 months. Dormancy treatment is the key and basis for the success of Rhododendron alpine blooming. At present, the low-temperature dormancy treatment of alpine rhododendrons in China is mostly done indoors, which takes up a lot of facility space. Some greenhous...
