Problems solved by technology

[0004] At present, certain achievements have been made in germplasm preservation and rapid propagation of Dendrobium candidum by tissue culture technology, but after several subcultures or due to factors such as improper use of hormones and culture environment, the tissue culture seedlings grow slowly and the proliferation rate is relatively slow. Low

Embodiment 1

[0048] A method for imitating wild planting of Dendrobium officinale in good growth, comprising the following steps:

[0049] (1) One-time cultivation: take the protocorm of Dendrobium officinale and cultivate it in the rooting medium until 1-2 true leaf heights of Dendrobium officinale seedlings of 1.5-2.5cm grow;

[0050] (2) Secondary culture: Take Dendrobium officinale seedlings with a height of 1.5-2.5cm and containing 1-2 true leaves, and inoculate them in the seedling medium at a temperature of 20-25°C in the day and 18-20°C at night. down until the seedlings grow to a height of 3-4cm and have 3-5 adventitious roots;

[0051] (3) taming seedlings: the seedlings obtained from the secondary culture are placed in the greenhouse for 25 days, and then continue to be cultivated outdoors for 8 days to obtain Dendrobium officinale plants;

[0052] (4) Planting: Choose a cliff wall with a shady face and the rock mass is glutenite; the planting time is from January to March, pla...

[0065] A method for imitating wild planting of Dendrobium officinale in good growth, comprising the following steps:

[0066] (1) One-time cultivation: take the protocorm of Dendrobium officinale and cultivate it in the rooting medium until 1-2 true leaf heights of Dendrobium officinale seedlings of 1.5-2.5cm grow;

[0067] (2) Secondary culture: Take Dendrobium officinale seedlings with a height of 1.5-2.5cm and containing 1-2 true leaves, and inoculate them in the seedling medium at a temperature of 20-25°C in the day and 18-20°C at night. down until the seedlings grow to a height of 3-4cm and have 3-5 adventitious roots;

[0068] (3) tame seedlings: the seedlings obtained from the secondary culture are placed in a greenhouse for 30 days, and then continue to be cultivated outdoors for 9 days to obtain Dendrobium officinale plants;

[0069] (4) Planting: Choose a cliff wall with a shady face and the rock mass is glutenite; the planting time is from January to March, place t...

Embodiment 3

[0082] A method for imitating wild planting of Dendrobium officinale in good growth, comprising the following steps:

[0083] (1) One-time cultivation: take the protocorm of Dendrobium officinale and cultivate it in the rooting medium until 1-2 true leaf heights of Dendrobium officinale seedlings of 1.5-2.5cm grow;

[0084] (2) Secondary culture: Take Dendrobium officinale seedlings with a height of 1.5-2.5cm and containing 1-2 true leaves, and inoculate them in the seedling medium at a temperature of 20-25°C in the day and 18-20°C at night. down until the seedlings grow to a height of 3-4cm and have 3-5 adventitious roots;

[0085] (3) tame seedlings: the seedlings obtained from the secondary culture are placed in a greenhouse for 20 days, and then continue to be cultivated outdoors for 7 days to obtain Dendrobium officinale plants;

[0086] (4) Planting: Choose a cliff wall with a shady face and the rock mass is glutenite; the planting time is from January to March, place t...

Abstract

The invention discloses a wild-imitating planting method of dendrobium officinale with good growth vigor, which includes steps of primary cultivation; secondary cultivation; seedling cultivation; planting: selecting night-faced cliff rock wall with rock body of glutenite; upwards fitting the dendrobium officinale plants to the cliff, and closely fixing roots of the stock trees to the smooth and waterlog-free cliff rock wall with slope of 80-90 degrees by an iron fixing buckle, wherein the planting time is January-March; the longitudinal planting space of the dendrobium officinale plants is 10-20m, and the cross planting space is 1-3m; topdressing: performing the first topdressing in 5th-7th days before the Qingming Festival, and spraying fluid fertilizer; pasting fertilizer to the root parts in the 5th-7th day after the winter begins; watering: watering for 2-3 times every day within 5-7 days after planting, and controlling the humidity at 75-85%; harvesting: harvesting after plantingfor 3-4 years. When the dendrobium officinale is planted by the method, the tissue culture seedling is good in growth and high in both of growth value and rate of increase; moreover, no hormone contains in a culture medium.

Description

technical field [0001] The invention relates to a wild-like planting method of Dendrobium officinale, in particular to a wild-like planting method of Dendrobium candidum in good growth condition. Background technique [0002] Orchidaceae (Orchidaceae) has more than 750 genera and more than 20,000 species. In addition to many species of flowers and leaves with high ornamental value, some species such as Dendrobium orchid have medicinal value. Dendrobium is divided into iron, yellow grass, There are several species such as golden hairpin, ring grass, Huoshan, horse whip, etc. Among them, Dendrobium ottYcinal Kimuraet Migo is the most precious. Dendrobium officinale, also known as Chlorophytum, Tiepilan, Chlorophytum, Yunnan Tiepi, is a perennial herb of the Orchidaceae Dendrobium genus. It is the top grade of Dendrobium medicinal materials. Its stems are used as medicine. Elements and amino acids and other active ingredients, in anti-tumor, improve the human body [0003] It...
