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
The present invention relates to a kind of plant cultivation technology; Florescence regulation technology particularly.
Background technology
The perennial perennial root herbaceous plant of little beautiful flower (Dahlia pinnata cv.) composite family dahlia, multiple color such as plant is comparatively short and small, highly only is 20 to 60 centimetres, and it is dark red, purplish red, pink, yellow, white that pattern has, flower shape is full of variety.Characteristics such as it is short to have plant, and the florescence is long, and pattern is gorgeous and abundant are widely used in many-sides such as flower bed, flower footpath, garden and cut-flower, potted flower production.Because little beautiful flower is cold-resistant, the winter growth amount is little, spends the required time of buddingging when blooming long, and the florescence is shorter, and inferior quality can not satisfy the demand in market in the Spring Festival.
Summary of the invention
The present invention provides a kind of little beautiful colored florescence control method for solving the technical problem that exists in the known technology, to satisfy market demand in its in Spring Festival.
The technical solution used in the present invention is: a kind of little beautiful colored florescence control method, expection is bloomed and is begun light filling preceding 2 beginning of the month, every day, illumination was 14 hours, every day, 8:00 carried out full sun to 18:10, and 18:00 was interrupted additional illumination to 3:00 employing in morning next day LED lamp, every irradiation in two hours hour, increase illumination 4 hours altogether, all the other periods, full the screening deceived, and kept intensity of illumination in illumination period between 10000～15000Lx, and the previous moon of blooming stops light filling; Once colored the more No. 12 (15-10-30) the 600 times of liquid (w/v) of pouring in per 3 days, bud stops to water rich water when showing look; The cultivation condition day temperature remains on 17～20 ℃, keeps 12～15 ℃ night, and humidity remains between 70%～75%.
Described light filling adopts the LED lamp, totally 120 lamp pearls, and red pearl quantity is 96～120, and blue lamp pearl quantity is 12～120, and the LED lamp is every 2 meters one, apart from 0.7 meter of plant height.
The good effect that the present invention has is: potted plant little beautiful the flowers are in blossom flower early, and the florescence than grown more than 30 day of conventional cultivation, the plant type compactness, the flowers are in blossom for full-bloom stage neatly, bright-colored, has higher ornamental value.
Embodiment
Test is divided into experimental group and control group, and experimental group is established six processing, and each handles little beautiful 200 basins of spending.
Experimental group experimental technique: begin light filling at the beginning of 11 months, every day, illumination was 14 hours, every day, 8:00 carried out full exposure to 18:10,18:00 is interrupted additional illumination to 3:00 employing in morning next day LED lamp, every irradiation in two hours hour, increase illumination 4 hours altogether, all the other periods, full the screening deceived, keep intensity of illumination in illumination period between 10000～15000Lx, the previous moon of blooming stops light filling.Described LED lamp has 120 lamp pearls (approximately 8W), and red light pearl quantity is 96～120, and blue lamp pearl quantity is 12～120, and its configuration sees Table 1, and the LED lamp is every 2 meters one, apart from 0.7 meter of plant height.Once colored the more No. 12 (15-10-30) the 600 times of liquid of pouring in per 3 days, bud stops to water rich water when showing look.Cultivation condition is that day temperature remains on 17～20 ℃, keeps 12～15 ℃ night, and humidity remains between 70%～75%.
The red blue lamp pearl proportioning of table 1 LED lamp
The control group experimental technique: control group adopts the incandescent lamp of 60W to carry out light filling, and every day, 8:00 carried out full exposure to 18:10, and 18:00 carries out continuous light filling to 20:00, and light filling is 4 hours altogether.Incandescent lamp is every 2 meters one, apart from 1.0 meters of plant heights.The same experimental group of cultivation condition and fertilizing method.Little beautiful 200 basins of spending.
The result is as follows:
Table 2 different light medium proportioning is to the little beautiful influence that the flowers are in blossom spends effect
Analyze: begin to observe the record result when buddingging.Adopt LED lamp light filling effect to be better than common incandescent lamp significantly, little beautiful the flowers are in blossom flower early, the florescence is long, and the potted flower quality better.The effect that red blue light is used is better than using separately red, blue light, the effect of experimental group 1,2 is best, budding to the required time comparison of blooming according to having shortened nearly 10 days, florescence contrasts has grown more than 30 day, and the plant type compactness, vane extension, full-bloom stage is spent neatly, bright-colored, have higher ornamental value.
Flower is No. 12 (15-10-30) fertilizer formulas the more: (following percentage is weight/percentage by weight)
Total nitrogen content is that 15% (wherein nitrate nitrogen content 8.73%, ammonium nitrogen content 1.92%, urea nitrogen content are 4.35%), water-soluble phosphoric anhydride content is 10%, the water soluble oxidized potassium content is 30%, the water soluble oxidized content of magnesium is 0.05%, and boron content is 0.0068%, and chelating attitude copper content is 0.0036%, chelating attitude iron content is 0.05%, chelating attitude manganese content is 0.025%, and chelating attitude zinc content is 0.025%, and molybdenum content is 0.0009%.
