Embodiment 1

[0022] The propagation method of the high position bud of Dendrobium chrysanthemum of the present invention comprises the following steps:

[0023] (1) Bud promotion at high position: From February 26th to the end of March in spring, spray nutrient solution on the whole plant of Dendrobium drumsticks every 2 weeks. The nutrient solution is in biogas slurry (biogas slurry is biogas tank liquid) to add urea so that the nitrogen content in the nutrient solution is 0.05% by mass fraction; the biogas slurry is prepared by the following method:

[0024] Use straw and cow dung as fermentation raw materials, fill the fermentation materials in the biogas tank, and add water, the mass ratio of straw and cow dung is 1:1, the amount of water added is 80% of the mass fraction of the fermentation raw materials, and the pH value is controlled at 7-8.0, use urea to adjust the carbon-to-nitrogen ratio (C / N) of the liquid in the biogas digester to 30:1, and after the biogas is generated, the fe...

Embodiment 2

[0030] Embodiment 2 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0031] (1) The germination promotion time of high-level buds is from February 16 to the end of March in spring, and the nitrogen content in the nutrient solution is 0.15% by mass. Use urea to adjust the carbon-to-nitrogen ratio (C / N) of the liquid in the biogas digester to 20:1.

[0032] (2) Cut off the high-position buds: Cut off the high-position buds together with 1 to 2 nodes of the bulb of the mother plant. After cutting, dip the incision in 70% mancozeb wettable powder 800 times solution for 4-5 seconds; place it on the planting bed Hang a sunshade net with a shading rate of 50%.

[0033] (3) Initial management of high-level bud seedlings: Do not apply fertilizer within two weeks after planting high-level buds, keep the air temperature at 26°C to 28°C, and water twice a week;

[0034] (4) Post-management of high-level bud seedlings: After the ...

Embodiment 3

[0038] Embodiment 3 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0039] (1) High bud bud promotion: ② In the spring, from February 26 to the end of March, on the upper part of the pseudobulb of Dendrobium chrysalis, use a small knife to draw a ring mark with a depth of 1mm to 2mm on the lower part of the stem node every 2 nodes, so that the pseudobulb can be injured and promoted. The generation of germination; Spray the nutrient solution described in embodiment 1 once every 2 weeks to the whole plant of Dendrobium chrysanthemum after circumcision.

[0040] Effect: High-position buds germinate in large quantities, the germination rate reaches 85%, and the survival rate of high-position bud seedlings is more than 98%. After transplanting, they grow rapidly and bloom within 23 months, achieving high yield. The average flower yield of Dendrobium drumsticks reaches 100kg / mu.

Abstract

The invention discloses a propagation method of dendrobiumchrysotoxumlindlphanerophyte. The method comprises the step of (1), budding phanerophyte, namely spraying nutrient solution on whole plant of the dendrobiumchrysotoxumlindl for one time every two weeks from mild-to-end of February to March in Spring, in which the nutrient solution is prepared adding carbamide into a biogas slurry and controlling content of nitrogen in the nutrient solution to be 0.05-0.15%; (2) cutting phanerophyte, namely cutting the phanerophyte and 1-2 sections of stock plant bulbus commonly when root grows to 2-4cm, dipping cutting notches in 600-800-fold solution of 70% mancozebwettable powder for 3-5 seconds, and then using moss to wrap the root and plant the root in a planting bed swallet; (3) performing initial management of phanerophyte seedlings; and (4) performing final-period management of the phanerophyte seedlings. Through the method, a large number of phanerophytes can be germinated; a germination rate is 80-90%; rate of survival of the phanerophyte seedlings is greater than or equal to 98%; the phanerophyte seedlings grow quickly and can flower in about 2 years; and yield of flowers reaches 80-110kg / unit of area.

Description

technical field [0001] The invention relates to a breeding method of the high buds of the rare medicinal and edible medicinal plant Dendrobium chrysanthemum. Background technique [0002] Drumstick Dendrobium (Dendrobium chrysotoxum Lindl.), also known as Golden Bow Dendrobium, is a plant of the genus Dendrobium in the family Orchidaceaceae. It grows on trees or damp rocks in tropical and subtropical forests, and is distributed in Yunnan, China. Province, Guangxi Province and other places are important forest medicinal plant resources in low latitude regions of my country. Dendrobium chrysalis is traditionally used as medicine with its fresh or dried stems. It is one of the commonly used medicinal species of Dendrobium in my country. Dry polydipsia, deficiency heat after illness, cloudy eyesight and other symptoms; it has obvious curative effect on throat and gastrointestinal diseases, cataracts, cardiovascular diseases, diabetes ([1] Bao Xuesheng, Shun Qingsheng, Chen Lizuan...
