The total inflorescence is terminal, 10-30 cm long, with yellowish red flowers; the flower stalk is short, 2-3 mm long; the bracts are membranous, narrow lanceolate or linearly oblong, about 1 cm long; the perianth tube is pitcher-shaped, with an oblique mouth, slightly enlarged at the base, and 5 small triangular lobes at the tip; the labellum is higher than the perianth tube by 2 / 3, with 3 lobes, the central lobe being larger and having a short stalk at the base; the gynostegium is 5-6 mm long, with 2 small appendages at the tip; the ovary is oblong, with a twisted ovary stalk. The capsule is oblong to oblong-oblong, about 15 mm long, with a short stalk. The seeds are numerous and small, in the form of dust. The flowering period is from June to July, and the fruiting period is from July to August.

[0003] Ginseng has been listed as a "material that is both food and traditional Chinese medicinal material", and its main components are: ginsengoside, ginsengoside base, beta-sitosterol, daucosterol, citric acid, monomethyl ester, palmitic acid, succinic acid and sucrose, etc.; it also contains ginseng polysaccharide, vitamin A, various amino acids, trace amounts of alkaloids, and various trace elements such as chromium, manganese, iron, cobalt, nickel, copper and zinc. Currently, the following methods are mainly used in large-scale production of ginseng:

[0004] (1) Fungus material companion planting method: dig a 40 cm deep pit, place the cultivated fungus rod at the bottom of the pit with a spacing of 5 cm. Place the ginseng on the fungus rod, and the two ends of the fungus rod also have ginseng, and the ginseng is close to the fungus rod. The rice ginseng is sown on both sides of the fungus rod. After planting one layer, fill the soil 3-5 cm, and it is appropriate that the bottom layer of fungus material is not visible. Use the above method to plant the second layer, and finally cover the soil 10-15 cm, slightly higher than the ground.

[0005] (2) Fungus material plus new rod cultivation method: generally use 10 fungus rods, place 5 cultivated fungus rods at the bottom, and then place 5 new fungus rods with no cultivation in between. Place the ginseng on both sides of the cultivated fungus material, and plant according to the fungus material companion planting method.

[0006] (3) Cultivation method of fungus bed: when cultivating, dig the cultivated fungus bed, take out the upper 5 fungus materials, and do not move the lower layer. Plant the Gastrodia elata Blume according to the fungus material companion planting method, and fill the soil by 3-5 cm. Then plant the second layer with the upper 5 fungus materials, and cover the soil by 10-15 cm. This method has high inoculation rate, fast survival, and high yield. The cultivated fungus bed can also be dug, 5 fungus materials are taken out, 5 new materials are added, and a new nest is planted. Then 5 fungus materials are taken out, 5 new materials are added, and another nest is planted.

[0007] (4) Cultivation method of ridge: make a ridge in the forest or slope of the forest edge, and leave a 30 cm working path between two ridges.

BRIEF DESCRIPTION OF DRAWINGS

[0025] Figure 1 It is the schematic diagram of the utility model Gastrodia elata Blume planting. DETAILED DESCRIPTION

[0026] The application will be further described in detail below in conjunction with examples, but the embodiments of the application are not limited thereto.

[0027] Example 1:

[0028] This embodiment relates to a Gastrodia elata Blume cultivation device, which carries out the cultivation and planting process of Gastrodia elata Blume by using plant essential oil extraction residue (rock guinea leaf residue, melaleuca alternifolia leaf residue and oil camphor tree leaf residue) as raw material. The plant leaf residue can replace the existing stick for Gastrodia elata Blume cultivation to provide nutrient components for Gastrodia elata Blume, ensure the growth of Armillaria mellea and Gastrodia elata Blume, reasonably lay the plant leaf residue, Armillaria mellea and Gastrodia elata Blume seeds, ensure the growth space of Gastrodia elata Blume, facilitate the heat preservation and moisture retention of Armillaria mellea and Gastrodia elata Blume during the planting process, and finally obtain Gastrodia elata Blume plants with low ash content, high moisture content and stable Gastrodin.

[0029] Ash content refers to the residue after complete burning of Gastrodia elata. Dry weight ratio refers to the weight ratio of dried Gastrodia elata to fresh Gastrodia elata. Gastrodin is an important quality assessment indicator of Gastrodia elata, with a content of not less than 0.25%. By testing the ash content, dry weight ratio, and gastrodin content of Gastrodia elata, a decrease in ash content indicates a decrease in inorganic substances such as calcium and silicon in the cultivated Gastrodia elata. An increase in dry weight ratio indicates an increase in organic components in the cultivated Gastrodia elata, with the gastrodin content reaching over 0.5%. This further demonstrates that the Gastrodia elata cultivation device provided in this embodiment can effectively control the inorganic and organic components in Gastrodia elata, stabilize the gastrodin content, and is conducive to ensuring the quality of Gastrodia elata cultivation and realizing large-scale production.

[0030] To ensure the quality of Gastrodia elata cultivation, reduce ash content, and increase dry weight and gastrodin content, the specific structure of the cultivation device and its cultivation method used in this embodiment can be summarized as follows:

[0031] Gastrodia elata is cultivated using a cultivation box or frame. First, a plastic sheet or bag is placed inside the cultivation box or frame, with holes approximately 3-10 mm in diameter made at the bottom and sides. Then, the following layers are laid from bottom to top inside the plastic sheet or bag: first layer of plant leaf residue, first layer of Armillaria mellea and Gastrodia elata seeds, second layer of plant leaf residue, second layer of Armillaria mellea and Gastrodia elata seeds, and third layer of plant leaf residue. (See [link to previous instructions]). Figure 1 As shown. After laying, cover the plastic sheet with raw soil or sand, or tie the opening of the plastic bag tightly. Then cover the Gastrodia elata cultivation box or Gastrodia elata cultivation frame with weeds or waste branches and place it in forest land above 1200 meters altitude for understory planting.

[0032] In the cultivation box or frame of Gastrodia elata, the first, second, and third layers of plant leaf residue are composed of at least one of Melaleuca alternifolia leaf residue, Cinnamomum camphora leaf residue, and Cinnamomum camphora leaf residue, respectively. For example, Melaleuca alternifolia leaf residue and Cinnamomum camphora leaf residue can be mixed and laid at the bottom of a plastic sheet or plastic bag with a thickness of 5-10 cm, and then Cinnamomum camphora leaf residue with a thickness of 5-10 cm can be laid to form the first layer of plant leaf residue; or Melaleuca alternifolia leaf residue and Cinnamomum camphora leaf residue can be mixed and laid on the first layer of Armillaria mellea. A 3-5 cm thick layer of *Gastrodia elata* seeds is then laid on top, followed by a 5-8 cm thick layer of *Cinnamomum camphora* leaf residue, forming a second layer of plant leaf residue. Alternatively, a mixture of *Melaleuca alternifolia* leaf residue and *Cinnamomum camphora* leaf residue can be laid on top of the second layer of *Armillaria mellea* and *Gastrodia elata* seeds, forming a third layer of plant leaf residue. The mixing of *Melaleuca alternifolia* leaf residue and *Cinnamomum camphora* leaf residue can also be done using only *Melaleuca alternifolia* leaf residue. Therefore, the weight ratio of *Melaleuca alternifolia* leaf residue to *Cinnamomum camphora* leaf residue can be limited to the range of 30-100:70-0.

[0033] The first layer of Armillaria and Gastrodia seed and the second layer of Armillaria and Gastrodia seed are uniformly distributed Armillaria and Gastrodia seed. To ensure the growth of Armillaria and Gastrodia and the reasonable layout of the growth space of Gastrodia, the amount of Armillaria in the first layer of Armillaria and Gastrodia seed is controlled to be 2-5 rods, and the amount of Gastrodia seed is controlled to be 5-12; the amount of Armillaria in the second layer of Armillaria and Gastrodia seed is controlled to be 2-5 rods, and the amount of Gastrodia seed is controlled to be 5-12. Rods or no rods (such as broad-leaved branches) can be used, and the amount of rods can be controlled to be less than 3 kg.

[0057] Based on the analysis of ash content, dry matter content and gastrodin content in Table 1, it can be seen that, compared with the traditional Gastrodia planting method (Comparative Example 1), the cultivation device of Example 1 can reduce the ash content of Gastrodia, increase the dry matter content and the content of gastrodin; compared with Comparative Example 2, although the use of broad-leaved branches as raw material can reduce the ash content of Gastrodia to a certain extent, increase the dry matter content and the content of gastrodin, but it cannot achieve the same effect as Examples 2 to 5, and the use of broad-leaved branches also increases the cost of raw materials, which is not conducive to the popularization of large-scale planting of Gastrodia; compared with Comparative Example 3, the use of three kinds of plant leaf residues mixed as raw material for Gastrodia planting, from the comparison of the data of Gastrodia ash content, dry matter content and gastrodin content, its effect is lower than that of Comparative Example 2 and Examples 2 to 5, and it cannot meet the ideal requirements of Gastrodia planting.

[0058] Further, according to the Gastrodia cultivation method of Example 2, batch planting was carried out in 10 same Gastrodia cultivation boxes, and the Gastrodia obtained by planting was subjected to ash content, dry matter content and gastrodin content detection, and the results are shown in Table 2.

[0060]

[0061] From the analysis of ash content, dry matter content and gastrodin content in Table 2, it can be seen that, when the cultivation device of Example 1 is used for Gastrodia planting, the content of inorganic matter and organic components in Gastrodia can be effectively controlled, the content of gastrodin can be stably controlled, the quality of Gastrodia can be effectively controlled, and it is conducive to batch planting of Gastrodia.

[0062] The above is only the preferred embodiment of the present application, and does not limit the present application in any form, and any simple modification or equivalent change of the above embodiment according to the technical essence of the present application falls within the protection scope of the present application.
