Embodiment 1

[0035] Embodiment 1: the imitation wild cultivation method of Gastrodia elata comprises the following steps:

[0036] 1) Tree species selection: select the broad-leaved tree Fagaceae Quercus genus Quercus as the tree species.

[0037]2) Material preparation: a. Armillaria: Dig wild Armillaria cord; b. Germination bacteria: purchased from outside; c. Leaf fragments: cut the fresh leaves of green bars into leaf fragments for later use; d. Substrate: take The soil below 50cm of the understory soil layer is mixed with leaf fragments at a ratio of 1:3.

[0038] 3) Breeding: a. Seed selection: Select a high-quality wild Gastrodia elata with a weight of 150g, no pests and diseases, and no damage, and put it in the wild for natural overwintering and dormancy in frost and snow. Take it out in February of the next year and plant it in the greenhouse The greenhouse can be made of bricks or prefabricated houses. The height is 3 meters and the width is 4 meters. The length depends on the ...

Embodiment 2

[0055] The difference between Example 2 and Example 1 lies in: step 1) selecting the broad-leaved tree Fagaceae Quercus genus Chrysanthemum as the tree species.

[0056] Step 2) a. Armillaria: Excavate stumps and roots covered with wild Armillaria mycelia as Armillaria strains.

[0057] Step 3) b. Breeding: Potted plants, planted in large plastic pots, filled the box with wet sand with a humidity of 50%, planted hemp, covered with film to keep warm and moisturized, checked frequently, found that the soil in the pot was dry, watered it appropriately, but not Too much to avoid rotten hemp. After the seedlings start to emerge, arch the film with a bamboo block to a height of 60cm to facilitate bolting. The emergence of Gastrodia elata is very inconsistent. When the seedling height is 20cm, transplant the seedlings and remove the weak ones; transplant the hemp seedlings of the same height together It is convenient for flowering and pollination; remove the film when the seedling he...

Embodiment 3

[0059] The difference between embodiment 3 and embodiment 1 lies in: step 1) choose the tree species of the broad-leaved tree as the tree species.

[0060] Step 4) is omitted, and the operation of loading fungi in step 5) is changed to: directly select wild Armillaria fungus cords, first insert part of the fungus cords into the fish scale mouth, and place the connecting branches obliquely in the gap between the main materials, and then place Cover with some fungus cords, 0.1kg of fungal cords for each cellar; or choose wild Armillaria spp., and sprinkle them in the fish scale openings and gaps of the main material, 1 kg per cellar; sprinkle another layer in the gaps of the main materials Fill the empty material, 1kg per cellar, cover with substrate, then cover with woven bag, sprinkle soil on the bag, cover dead branches, fallen leaves, weeds on top to keep moisture and keep warm.

[0061] The present invention selects the Dalou Mountains as the test site, which is located in ...

Abstract

The invention discloses a cultivation method imitating wild conditions for Gastrodia elata Bl. f. glauca S. Chow, relating to the technical field of planting of traditional Chinese medicinal materials, and comprising the following steps: (1) selection of tree species; (2) material preparation: a, Armillaria mellea: digging wild Armillaria mellea rhizomorph or stubs and roots overgrown with wild Armillaria mellea hyphae, chopping the stubs and roots into wood blocks as wild Armillaria mellea fungal wood blocks; (3) breeding; (4) preparation of fungal sticks; (5) culture of a fungal bed: a, material preparation: selecting the tree species in the step 1, cutting the tree species 20-30d in advance, drying the tree species in the sun to dehydrate the tree species for 30%; b, land selection; c, soil preparation; d, land preparation; e, pit digging; f, loading of the fungal bed; (6) seeding; (7) management: a, thinning, reseeding, bag removing, earth backing; b, ditch cleaning, draining, drought prevention, light adjusting; c, disease and insect damage prevention and control; and (8) excavation and nutrition supplementing. The method is executed in a vacant field in the forest for planting, adopts wild Armillaria mellea for accompanying planting, and provides the optimal growing environment for the Gastrodia elata Bl. f. glauca S. Chow through fine management, thereby providing a basis for high yield and high quality of Gastrodia elata Bl. f. glauca S. Chow.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a method for imitating wild cultivation of Gastrodia elata. Background technique [0002] Gastrodia elata is a species of the genus Gastrodia in the family Orchidaceae, also known as Gastrodia elata. It is named for its black-brown tubers, black-red flower stems, green or dark green flowers, and its main medicinal ingredient, gastrodin, is a species of Gastrodia elata. The top grade among them mainly grows in the alpine forest area at an altitude of 1500-2000m. Affected by the rise of the earth's temperature and human destruction of resources, there are not many wild resources in the country, and the output has decreased sharply. It has been included in the list of endangered species in the world. Gastrodia elata's tillering and reproductive ability is not as high as that of Gastrodia elata, and its planting yield has always been low, with a yield of...
