Flowering phase regulation method for azalea

Abstract

The invention relates to a flowering phase regulation method for azalea, which is characterized by the following steps of: starting flower forcing two months before the expected flowering phase, controlling the greenhouse temperature to be 10 DEG C or so, controlling the room temperature to be 20 DEG C 20 days before the expected flowering phase, and thus enabling flowers to bloom at the expected flowering phase; when EC is smaller than 0.4, alternately watering the flowers with an aqueous solution containing Peters Professional 20-10-20 with a content of 1-1.2g / L or an aqueous solution containing KNO3 of 0.6-0.7g / L and MgSO4 of 0.4-0.5g / L based on the principle of not watering until being dried; and when EC is greater than 0.4, only watering the flowers with clean water of which the PH value is 6.0-6.5, and keeping the flowered illuminated for more than 8 hours everyday, wherein the illumination intensity is kept at 15000lux, and at the flower forcing phase, the daytime humidity is 70-80%, and the nighttime humidity is 75-85%.

Description

technical field [0001] The invention belongs to the field of flower cultivation methods; in particular, the field of rhododendron cultivation methods. Background technique [0002] Rhododendron, Rhododendronaceae, Rhododendron genus, Rhododendron likes a cool, humid, and ventilated semi-shady environment. It is afraid of extreme heat and cold. When the temperature exceeds 35°C in summer, the new shoots and leaves grow slowly and are in a semi-dormant state. Avoid hot sun exposure, suitable for growing under scattered light with low light intensity. If the light is too strong, the young leaves are easy to be burned, and the new leaves and old leaves are scorched. In severe cases, the plant will die. Rhododendrons are very beautiful. Tubular flowers come in various colors such as crimson, light red, rose, purple, and white. When the rhododendrons bloom in spring, the mountains are full of bright colors, like clouds surrounding the forest. It has 5 petals, and there are some ...

Problems solved by technology

[0003] Rhododendron is a seedling imported from abroad. Currently, only a small amount of this variety is listed on the market. Because this variety comes from abroad, there is no mature cultivation technology in China, especially in the north of the Yangtze River in China, where the climate is relatively dry and the four seasons are relatively distinct. The winter is relatively cold, and rhododendrons that have not been regulated in flowering period are prone to flower deformities and impure colors, small buds, growth points that cannot produce flowers normally, and cannot make them bloom out of season according to market demand. Its quality requirements are getting higher and higher
