Problems solved by technology

[0003] Generally, Gastrodia elata sexually propagated white and rice hemp species, due to the low germination rate of the seeds themselves and although they can germinate, many seeds cannot be inoculated with the fungus and cannot grow in time, resulting in low yield and extremely unstable

Embodiment 1

[0015] 1. Cook 30cm-long miscellaneous wood sticks at 90°C for 0.5 hours, take them out and cool them, and put them on the fungus bed. The fungus bed is 20 cm deep, one meter wide and one meter long. sticks, the distance between the ends of each stick is 2 cm, and the horizontal sticks can be placed side by side, and the end of each stick is filled with solid Amygdalus the size of a walnut, and the sand is filled to 5 cm on the stick surface. good bacteria sticks;

[0016] 2. Cut the fallen leaves of Fagaceae collected in the first year into 2-4 mm diameter pieces after being dried and developed after sterilizing the fallen leaves of Fagaceae, and cut them into pieces with a diameter of 2-4 mm. Add 2 grams of glucose per 100 ml to the juice until the water content is about 60%, then add mature Gastrodia elata seeds (6-8 sycamores per square meter), and mix well to obtain a mixture of Gastrodia elata germination bacteria;

[0017] 3. Immerse the bacterium stick that has been i...

Embodiment 2

[0021] A method for sexual reproduction of Gastrodia elata,

[0022] Include the following steps:

[0023] (1) Two months before the seeds mature, cook the miscellaneous wood sticks at 80-90°C for 30 minutes, take them out and cool them, and put them on the fungus bed to inoculate the fungus to obtain high-quality fungus sticks that have been inoculated with the fungus;

[0024] (2) Sterilize the fallen leaves of Fagaceae collected in the first year and dry them for later use, then cut or knead the well-developed solid germination bacteria into pieces with a diameter of 2-4 mm, and finally combine the dried fallen leaves with the germination bacteria Stir the fragments evenly, add high-temperature sterilized miscellaneous sawdust juice until the water content is about 60%, add Gastrodia elata seeds and mix well to obtain germination fungus material containing Gastrodia elata seeds, add about 2 grams per 100 ml of the miscellaneous sawdust juice glucose, the dosage of Gastrodi...

Abstract

The invention discloses a sexual propagation method for gastrodia elata, which comprises the steps of: steaming weed tree sticks, placing the weed tree sticks on a fungal bed for inoculating Armillaria mellea, soaking fungus sticks which are inoculated with the Armillaria mellea in Armillaria mellea solution, rolling the fungus sticks for a turn in mixture of gastrodia elata seeds and germinationstrains and finally operating according to a conventional gastrodia elata production method. The sexual propagation method for gastrodia elata has the advantages that the germination rate of the gastrodia elata seeds is high and the yield of white gastrodia elata and rice-sized gastrodia elata is high; and when the weed tree sticks are steamed at high temperature, the goal of sterilization is realized, the Armillaria mellea can be more easily inoculated on the seeds, the problem that many seeds cannot be inoculated with the Armillaria mellea in time can be solved by soaking the fungus sticks in the Armillaria mellea solution, the Armillaria mellea can be more easily inoculated and the seed yield for the sexual propagation of the gastrodia elata is greatly improved.

Description

technical field [0001] The invention relates to the field of Gastrodia elata propagation, in particular to a method for sexual propagation of Gastrodia elata. Background technique [0002] Gastrodia elata is a perennial herb distributed in most parts of the country. Its dry tubers, also known as Gastrodia elata, are commonly used and relatively expensive traditional Chinese medicines. They are mostly used clinically for headaches, dizziness, numbness of limbs, convulsions in children, epilepsy, convulsions, and tetanus. Gastrodia elata has always relied on wild resources in the past. After the successful conversion from wild to artificial cultivation in the 1970s, artificial cultivation of Gastrodia elata has become the main source of commodities. [0003] Generally, Gastrodia elata's sexually propagated white and rice hemp species suffer from low germination rate of their seeds and although they can germinate, many seeds cannot be inoculated with Cyclobacterium in time and...
