Embodiment Construction

[0007] The experiment was divided into an experimental group and a control group. The experimental group had six treatments, each with 200 pots of Xiaolihua.

[0008] The experimental method of the experimental group: light supplementation began in early November, 14 hours of light per day, full light from 8:00 to 18:10 every day, and intermittent supplementary light with LED lights from 18:00 to 3:00 the next morning, every two Irradiate for one hour per hour, increase the light for 4 hours in total, cover the rest of the time in darkness, keep the light intensity between 10000-15000Lx during the light period, and stop supplementary light one month before flowering. The LED lamp has 120 lamp beads (about 8W), the number of red lamp beads is 96-120, and the number of blue lamp beads is 12-120. The configuration is shown in Table 1, and the LED lamps are set every 2 meters. 0.7 meters. Water 600 times of Huaduoduo No. 12 (15-10-30) every 3 days, and stop watering when the flow...

Abstract

The invention relates to a method for regulating florescence of dwarf dahlia. The method comprises the steps of: starting supplementing light in the beginning of two months before the expected flowering; lighting for 14 hours every day; carrying out full light from 8:00 to 18:00 every day; discontinuously supplementing light by utilizing an LED (Light Emitting Diode) lamp from 18:00 to 3:00 the next day morning, irradiating for an hour every other two hours, increasing the light time to 4 hours in all; keeping in the darkness at other periods and maintaining the light intensity between 10000-15000Lx during the light periods; stopping supplementing light one month before the flowering; watering by utilizing 600 times liquid of Peters professional 12 once every 3 days; and stopping the watering of fertilizer water when flower buds present color, wherein the cultivation conditions are that the temperature is maintained at 17-20 DEG C during daytime, the temperature is maintained at 12-15 DEG C during nighttime, and the humidity is maintained between 70% and 75%.

Description

technical field [0001] The present invention relates to a kind of plant cultivation technique; especially the florescence regulation technique. Background technique [0002] Dahlia pinnata (Dahlia pinnata cv.) is a perennial herbaceous plant belonging to the family Asteraceae. The plant is relatively short, with a height of only 20 to 60 cm. The flower colors are deep red, purple, pink, yellow, white and other colors. Variety. It has the characteristics of low plant, long flowering period, bright and rich flower colors, etc. It is widely used in flower beds, flower paths, courtyards, cut flowers, potted flowers, etc. Because Xiaolihua is not cold-resistant, its growth is small in winter, it takes a long time from budding to flowering, the flowering period is short, and its quality is poor, which cannot meet the needs of the Spring Festival market. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention pr...
