Embodiment 1

[0011] The concrete steps of Dendrobium officinale full light artificial cultivation method of the present invention are as follows:

[0012] a. Select a strong tissue culture seedling with a height of 8cm to go out of the bottle, place it in a substrate mixed with lichen or tree moss or perlite and peat soil at a ratio of 2:1 to harden the seedlings, and spray it in time under the condition that the light transmittance is 25%. Water, control the relative humidity of the environment within 60%, keep ventilated, start spraying the nutrient solution after 7 days, and the cycle of spraying the nutrient solution is 7 days;

[0013] b. After hardening the seedlings for 2 months, move to an environment with a light transmittance of 60% to adapt for 25 days; then move to an environment with a light transmittance of 80% to adapt for 10 days; finally move to a position 1.5m above it for installation Cultivate under full light conditions in the cultivation seedbed with sprinkler irrigat...

Embodiment 2

[0016] a. Select the sturdy tissue culture seedlings with a height of 6cm to take out of the bottle, place them in the moss matrix to harden the seedlings, spray water in a timely manner under the condition of light transmittance of 28%, control the relative humidity of the environment within 65%, and keep ventilated , start spraying nutrient solution after 7 days, and the cycle of spraying nutrient solution is 7 days;

[0017] b. After 2 months of seedling hardening, move to an environment with a light transmittance of 50% to adapt for 30 days; then move to an environment with a light transmittance of 90% to adapt for 12 days; finally move to a position 1.5m above it for installation Cultivate under full light conditions in the cultivation seedbed with sprinkler irrigation device;

[0018] c. Under full light conditions, timely spraying of water and regular spraying of nutrient solution is required. The cycle of spraying nutrient solution is 10 days; the relative humidity of ...

Embodiment 3

[0020] a. Select the sturdy tissue culture seedlings with a height of 4cm out of the bottle, place them in a matrix mixed with perlite and peat soil at a rate of 2:1, and spray water in a timely manner under the condition of a light transmittance of 30%, and control the environment relatively The humidity is within 70%, keep ventilated, start spraying nutrient solution after 7 days, and the cycle of spraying nutrient solution is 7 days;

[0021] b. After hardening the seedlings for 2 months, move to an environment with a light transmittance of 55% to adapt for 30 days; then move to an environment with a light transmittance of 85% to adapt for 15 days; finally move to a position 1.5m above it for installation Cultivate under full light conditions in the cultivation seedbed with sprinkler irrigation device;

[0022] c. Under full light conditions, it is necessary to spray water and nutrient solution regularly, and the cycle of spraying nutrient solution is 10 days; the relative ...

Abstract

The present invention relates to a dendrobium officinale full-light artificial cultivation method, which belongs to the cultivation technical field of the Chinese medicinal material cultivation. The specific process is that a strong tissue culture seedling in the height of four to eight centimeters is selected to be trained in the substrate mixed by the lichen, the tree moss or the perlite with the peaty soil in a proportion 2 :1 under the conditions of 25 percent to 30 percent transmittance and the appropriate watering and the ambient relative moisture is controlled within 60 percent to 70 percent and keeping the ventilation; sever days later, the seedling is sprayed with nutrition liquid; the spraying nutrition-application period is seven days; after training the seedling for two months, the seedling is moved to an environment with the transmittance of 50 percent to 60 percent for the adaptation for 30 days; the seedling is moved to an environment with the transmittance of 80 percent to 90 percent for adaptation for ten to fifteen days; finally, the seedling is moved to be cultivated on a culture seedling bed that is provided with an irrigation device 1.5 meters above under the full light condition; under the full light condition, the seedling is watered at a proper time and applied with nutrition liquid periodically and the nutrition spraying-application period is ten days; the culture ambient relative moisture is controlled within 60 percent to 80 percent; 1.5 to 2 years later, the Chinese medicinal material-the dendrobium officinale with high yield and high content of the effective composition of the medicine can be harvested. The present invention has the advantages of simple operation, low cost, good benefit, excellent quality and high yield.

Description

Technical field: [0001] The invention relates to a full-light artificial cultivation method of dendrobium officinale, which belongs to the technical field of cultivation of traditional Chinese medicinal materials. Background technique: [0002] At present, reports on the growth and development of Dendrobium candidum and its cultivation methods generally believe that the artificial cultivation of Dendrobium candidum requires the use of sunshade nets for shading treatment. However, through our research, we found that Dendrobium officinale is a light-loving positive plant, and only under full light can it achieve the maximum photosynthetic accumulation and the highest growth rate. In cultivation experiments, it was also found that the growth and medicinal components of Dendrobium candidum under shading conditions were lower than those grown under full light conditions, and the cultivation cost was much higher than that under full light cultivation. [0003] Through document se...
