Embodiment 1

[0042] The dwarfing potted method of embodiment 1 cut flower variety " Lucita 1 powder edge " (seed seedling)

[0043] (1) Cultivation of Eustoma potted seedlings

[0044] Variety selection: There are hundreds of cut flower varieties of eustoma for commercial use, and the varieties with early maturity, strong tillering ability, large number of flowers, small leaves, high stem hardness and short plant height in flowering stage should be selected as potted plants first. varieties.

[0045] The variety "Luxita 1 Fenbian" selected in this example has the characteristics of early maturity, strong tillering ability, small leaves, strong continuous growth of stems, and is sensitive to day length and temperature response, which meets the requirements for potted plants.

[0046] (1) Sowing seedlings

[0047] ①Refrigeration of germinated seeds: sow Eustoma seeds on the surface of the plug seedling substrate without any substrate covering. Use spray or sprinkler irrigation to fully ab...

Embodiment 2

[0062] The dwarfing potted method of embodiment 2 early-maturing cut flower varieties "Mary Green" (cutting seedlings)

[0063] Embodiment 2 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0064] (1) Cultivation of variety "Mary Green" cutting seedlings:

[0065] Choose the eustoma cut flower variety 'Mary Green' for dwarf pots. Mary green has the characteristics of early maturity, fast growth, many branches, many flowers, large flowers and short plants, which meets the requirements of potted plants.

[0066] ① For the cultivation of the cutting female parent, the sunshine length of the "Mary Green" female parent cultivation should be controlled within 9-11 hours

[0067] During the day, the night temperature is kept between 10-13°C, and the day temperature is kept between 18-23°C.

[0068] ②Picking cuttings, micro-picking at the stage of 4-6 leaves of the female plant to promote the germination of the first-level ...

Embodiment 3

[0077] Example 3 Utilizing the three-dimensional climate of the low-latitude plateau to realize the dwarfing potted plant of Eustoma cut flower variety in greenhouse

[0078] The dwarf potted plants of eustoma cut flowers can achieve annual planting production in a greenhouse with strong light, temperature and humidity control. However, taking advantage of the natural conditions of the three-dimensional climate in the low-latitude plateau areas of the northern hemisphere, that is, it has long sunshine in summer and short sunshine in winter, and the temperature drops by about 0.6°C every time the altitude rises by 100 meters. Reduce the energy cost of greenhouse environment control, and greatly reduce the production cost of greenhouse potted flowers.

[0079] Embodiment 3 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0080]Variety selection: In this example, the eustoma cut flower variety "Super Magic Purple Edge" i...

Abstract

The invention discloses a greenhouse dwarfing and potting method of an eustoma grandiflorum cut flower variety. Through gardening measures and ecological factor adjustment, the method includes the steps of conducting processing for 10-11 hours at low night temperature of 10-13 DEG C in short daylight, conducting micro pinching 1-2 times and spraying cytokinin in the early period of eustoma grandiflorum production, conducting processing at high night temperature of 18-22 DEG C for long illumination duration of 14-16 hours in the later period of production, and cooperatively taking measures like applying of dwarfing agent in the bolting and flowering period and semi-arid management. By means of the method, the greenhouse dwarfing and potting of the eustoma grandiflorum cut flower variety are achieved, and the defect that eustoma grandiflorum potted varieties mainly include single-petal small flowers and are few in variety number and simplex in flower color and flower shape are overcome. By means of the method, the eustoma grandiflorum potted product which is rich in flower color, diversified in type, long in ornamental period, large in flower and heavy in petal can be obtained.

Description

technical field [0001] The invention relates to a method for realizing dwarf potted planting of eustoma cut flower varieties in a greenhouse through horticultural measures and adjusting ecological factors, and belongs to the technical field of plant planting. Background technique [0002] Eustoma grandiflorum (Eustoma grandiflorum), also known as prairie gentian, is an ornamental plant of the Gentianaceae Eustoma genus native to central and southern North America. It is mainly used for cutting vases and making flower baskets. Lisianthus eustoma has a beautiful and elegant flower shape, fresh and beautiful, and has a long shelf life. It has the reputation of "thornless rose". Eustoma is the fastest-growing category of fresh cut flowers in the world in the past two decades. In terms of sales, it is comparable to rose sales in Japan and ranks fourth among the main cut flowers in Yunnan Province, China. [0003] In recent years, there has been a certain increase in the applica...
