Problems solved by technology

Part of the leaves can be removed to reduce the shading of the leaves to the early inflorescences of gerbera, but this method is not good for the vegetative growth of the plant and requires a lot of work

Embodiment 1

[0027] The LED light is hung above the gerbera plant, 10cm away from the stem node. The light intensity at the first inflorescence is 60μmol.m -2 .s -1 , the light intensity at the first inflorescence of the control group was 25 μmol.m -2 .s -1 , the fill-in light time is from 8:00 am to 16:00 pm, and the fill-in light is continued for 6 days, and then the fill-in light is stopped. The coloring of petals was measured on the 9th day after stopping the supplementary light (see Figure 4 ).

Embodiment 2

[0029] The LED light is hung above the gerbera plant, 10cm away from the stem node. The light intensity at the inflorescence at the first stage reaches 70μmol.m -2 .s -1 , the light intensity at the first inflorescence of the control group was 25 μmol.m -2 .s -1 , the fill-in light time is from 8:00 am to 16:00 pm, and the fill-in light is continued for 6 days, and then the fill-in light is stopped. The coloring of petals was measured on the 9th day after stopping the supplementary light (see Figure 5 ).

Embodiment 3

[0031] The LED light is hung above the gerbera plant, 10cm away from the stem node. The light intensity at the first inflorescence is 80μmol.m -2 .s -1 , the light intensity at the first inflorescence of the control group was 25 μmol.m -2 .s -1 , the fill-in light time is from 8:00 am to 17:00 pm, and the fill-in light is continued for 6 days, and then the fill-in light is stopped. The coloring of petals was measured on the 9th day after stopping the supplementary light (see Image 6 ).

Abstract

The invention discloses a method for promoting petal coloring of gerbera jamesonii. The method comprises the steps as follows: inflorescence of gerbera jamesonii is supplemented with light through LED lamps from the stage, the lighting intensity at the inflorescence part is greater than 60 mumol.m<-2>.s<-1>, and the light is supplemented for 7 to 9 hours in the daytime and continuously supplemented for 5 to 6 days. According to the invention, the early inflorescence of gerbera jamesonii is supplemented with light through LED lamps, so that the time for supplementing light is short, growing and coloring of pedals can be promoted remarkably without consumption of tremendous light energy, the quality of gerbera jamesonii is improved effectively, the operation is simple, the cost is low, and the method can be applicable to the greenhouse production of gerbera jamesonii at all seasons.

Description

technical field [0001] The invention relates to a flower plant cultivation technology, in particular to a method for promoting coloring of gerbera chrysanthemum petals. Background technique [0002] Gerbera is a light-loving plant, and a certain intensity of light is an important condition for the formation of the quality of gerbera inflorescences. In production, due to insufficient light, the growth of gerbera ray flowers will be hindered, the color of petals will become lighter, and the ornamental value will be lost. However, in China, there is no application and report of artificial supplementary light in the production process of gerbera. In foreign countries, some gerbera growers in the Netherlands implement artificial supplementary light on gerbera in winter. In this supplementary light technology, artificial light is used as an energy source to improve the photosynthesis of plant leaves and improve the growth of plants. , so as to increase the yield of flowers, this...
