Problems solved by technology

[0002] Gerbera jamesonii (Gerbera jamesonii) is a perennial herbaceous flower of the genus Gerbera in the Compositae family. It is also known as Gerbera and Gerbera. It is native to South Africa and is also distributed in a small amount in Asia. It was introduced to China in the mid-1980s. Gerbera blooms every year , can be used as cut flowers or potted flowers. It has the characteristics of large and colorful flowers, rich colors, and can produce flowers in all seasons. It has high ornamental value. It has become the fifth largest fresh cut flower in the world. Therefore, it is deeply loved by consumers. As a cut flower, gerbera has some unsatisfactory problems: mainly low lignification, easy drooping flower heads, easy bending and breaking of flower stems, etc., which seriously affect its viewing value
Gerbera is C 3 For plants, the phenomenon of photosynthetic lunch break is very obvious. The research on the photosynthetic characteristics of gerbera shows that the diurnal change of the net photosynthetic rate (Pn) of its leaves shows an obvious double-peak phenomenon, and the first peak appears at 9:00-10:00 in the morning , is the highest value of the whole day, after which Pn gradually weakens, and a "lunch break" phenomenon appears around 14:00; the second peak appears around 16:00, but it is 22.6% lower than the Pn of the first peak; in addition, the gerbera CO 2 The saturation point is

Embodiment 1

[0088] 1. Facilities selection: glass greenhouse, the top layer of the greenhouse is covered with sunshade nets, the light transmittance of the sunshade nets is 30%, the light intensity maintains natural light, and maintains the temperature and humidity under natural conditions.

[0089] 2. Plant the gerbera cultivar "gouache" at the seedling stage for two months, and plant it in a pot; use conventional methods for daily cultivation and management, that is, the cultivation and management methods commonly used for planting gerbera in the greenhouse.

[0090] 3. CO 2 Pipe layout of the external hose of the instrument: the external hose is evenly distributed on the top of the plant leaves in parallel, 10cm away from the leaves, and the distance between the gas diffusion holes on the external hose is 50cm.

[0091] 4. CO 2 Enrichment: set CO 2 CO of the controller 2 The concentration is 800μmol·mol -1 , CO 2 The gas is applied around the leaves of the plants through the contr...

Embodiment 2

[0095] 1. Facilities selection: plastic greenhouse, the top layer of the greenhouse is covered with sunshade nets, the light transmittance of the sunshade nets is 30%, the light intensity maintains natural light, and maintains the temperature and humidity under natural conditions.

[0096] 2. The gerbera cultivar "gouache" in the flowering stage is planted in the border; the daily cultivation management adopts the conventional method, that is, the cultivation management method usually used for planting gerbera in the greenhouse.

Abstract

The invention discloses a method for improving quality of a cut flower of gerbera by utilizing CO2. A timed and quantitative enriching technology of the CO2 is adopted, a nitrogenous fertilizer using measure is combined, and the interaction of the carbon-nitrogen metabolism is utilized, so that the flowering time of the gerbera is advanced, the diameter of the flower is enlarged, the number of the flower in a single plant is increased, the color of the flower is deepened, the consistency of the flower is good, the vase life of the cut flower is prolonged, the method is suitable for the gerbera planted by a conventional method in a green house, gerbera in different cultivars and different growth periods, the production cost is reduced, and besides, the generation of the greenhouse effect is avoided.
