Embodiment 1

[0013] 1. Materials and methods:

[0014] 1-1 Test materials and design:

[0015] A total of 112 healthy adult plants of P. sclerophyllum were selected and cultivated in a cultivation medium with a ratio of mulch, broken bricks and bark of 1:1:1. The daily average temperature of the cultivation greenhouse was 18°C. Different hormones were applied to the plants. Different concentrations of treatment, the control group sprayed with water, a total of 7 treatments, each treatment 16 plants (see Table 1)

[0016]

[0017] Use a ruler to measure the leaf length and leaf width of each plant, and calculate the leaf area (leaf area = leaf length × leaf width × leaf area coefficient 0.684), according to the leaf area of ​​the plant at 0.2L / m 2 The amount of spraying sprayed the phytohormones of the above-mentioned concentration on the blade of Paphiopediphyllum sclerophyllum with a micro-sprayer, and the spraying time was on September 3, 2009.

Abstract

The invention discloses a method for adjusting flowering period of paphiopedilum micranthum. The method for adjusting flowering period of paphiopedilum micranthum comprises the steps of treating a grown plant of paphiopedilum micranthum with gibberellins GA3 and 6-benzylpurine 6-BA of different concentrations; when the gibberellins GA3 is used for treatment, the concentrations are respectively 100mgL-1, 200mgL-1 and 400mgL-1; and when the 6-benzylpurine 6-BA is used for treatment, the concentrations are respectively 100mgL-1, 200mgL-1 and 400mgL-1. According to the market demand, different hormones of different concentrations are used for adjusting the flowering rate, the flowering time, the flowering period and the length of scape, and the method speeds up flowering of the paphiopedilum micranthum by 54 to 70 days. The flowering period adjusting method of paphiopedilum micranthum disclosed by the invention is characterized by high operability, obvious control effect and the like, canprovide operable technical support for commercial flower production of paphiopedilum micranthum.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for regulating the flowering period of P. sclerophyllum. Background technique [0002] Paphiopediphyllum ( Paphiopedilum micranthum ) is the genus Paphiopedilum in the family Orchidaceae ( Paphiopedilum ) plants, concentrated in China's Yunnan, Guizhou, Guangxi and other places and northern Vietnam, growing in limestone areas and shrubs or in crevices of rocks under forests at an altitude of 400-1700m; with several or more transverse walking stems , 1.5-2.5mm in diameter, 3-5 leaves, large and showy flowers, scape 10-30cm, deep sac-shaped lips, oval spherical. Pedrophyllum sclerophyllum has the characteristics of peculiar flower shape, gorgeous flower color, and long flowering period. It has high ornamental value and cultivation value. Paphiopedilum is also known as "golden boy and jade girl", and it is a treasure among orchids. [0003] In recent years, due...
