Description

Technical Field

[0001] This utility model relates to the field of Gastrodia elata cultivation technology, specifically to a Gastrodia elata slope planting structure. Background Technology

[0002] Gastrodia elata, also known as Chijian, Duyaozhi, Limu, Helicao, Shencao, Guiduyou, Mupu, Mingtianma, Dingfengcao, Bailongpi, etc., is a perennial herb belonging to the genus Gastrodia in the Orchidaceae family. It has a thick rhizome without green leaves, and produces obovate-elliptic capsules. It is commonly propagated by tubers or seeds. Its rhizome is used medicinally to treat dizziness, numbness of limbs, and infantile convulsions. It is a valuable traditional Chinese medicine and is often used in combination with Ganoderma lucidum (reishi mushroom) to treat headaches and insomnia.

[0003] Gastrodia elata is a unique plant that lacks roots and green leaves. It has no organs for absorbing or producing nutrients and cannot be autotrophic. Its epidermal tissue can only absorb water and inorganic salts from the soil. The nutrients it needs for growth and reproduction come from Armillaria mellea, making it a typical heterotrophic plant. Armillaria mellea decomposes cellulose and lignin in wood to provide the nutrients needed for its growth, while Gastrodia elata obtains its nutrition by digesting and infecting the mycelium of Armillaria mellea.

[0004] Currently, the traditional cultivation method of Gastrodia elata mainly selects gentle slopes or valleys rich in organic matter. The soil with a pH of 5-6, loose texture, and good drainage is preferred, especially virgin wasteland. The traditional cultivation process is highly dependent on the environment, has low production efficiency, and is at high risk of fungal infection and pests. The open-air pit environment cannot effectively isolate miscellaneous bacteria and pests, the fungal material is easily contaminated, and the water and soil conservation capacity is poor. During the rainy season, it is easy to cause soil erosion, which not only affects the growth environment of Gastrodia elata, but also has an adverse impact on the mountain ecology. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a Gastrodia elata slope planting structure, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: A planting structure for Gastrodia elata on a slope includes a main slope, with planting holes excavated at the slope position of the main slope, and an inwardly inclined base slope at the bottom of the planting hole. The planting hole is provided with a drainage layer, an insect-proof layer, a planting layer and a buffer layer stacked in sequence from bottom to top. The drainage layer is composed of a layer of oak wood and a first layer of crushed stone. The insect-proof layer includes a geotextile and an insect-proof agent layer. The insect-proof agent layer is laid on the upper surface of the geotextile. The planting layer is stacked on the insect-proof agent layer. An ecological protection layer is provided above the buffer layer. The planting layer is equipped with a vertical isolation plate, which divides the planting layer into several independent planting modules. The vertical isolation plate and the inner side wall of the planting hole are both fitted with an anti-escape liner.

[0006] As an improvement to the above scheme, the oak wood layer is composed of several oak wood strips, the arrangement direction of the oak wood strips is consistent with the slope inclination direction of the main body of the slope, and the first crushed stone layer is laid in the gap between two adjacent oak wood strips and at the bottom of the oak wood layer.

[0007] As an improvement to the above scheme, the slope of the main body of the slope is provided with a water interception ditch above the planting hole. The water interception ditch extends along the contour line of the slope and has a turf layer and a second gravel layer from top to bottom in the water interception ditch.

[0008] As an improvement to the above solution, an ecological bag retaining wall is also built on the slope surface of the main body of the slope corresponding to the lower edge of the planting hole. The ecological bag retaining wall is composed of several ecological bags filled with a mixture of soil and grass seeds stacked layer by layer in a staggered triangular pattern.

[0009] As an improvement to the above solution, the escape-proof liner is a microporous metal mesh, and the vertical height of the vertical isolation plate is consistent with the thickness of the soil filling in the planting layer.

[0010] As an improvement to the above solution, a guide pipe is also provided in the planting hole. The wall of the guide pipe has several micro-holes. The guide pipe is buried at the bottom of the water storage and drainage layer, and its axis is parallel to the contour line. Both ends of the guide pipe extend and pass through the side wall of the planting hole.

[0011] As an improvement to the above scheme, the buffer layer is formed by piling up pine needles and straw, the insect-proof layer is a powdered diatomaceous earth layer, and the ecological protection layer includes the original slope topsoil and local herbaceous plant seeds, which are backfilled and covered on the buffer layer.

[0012] The beneficial effects of this utility model are as follows: the planting hole in this technical solution is equipped with a drainage layer, an insect-proof layer, a buffer layer, and an ecological protection layer in stages. The planting layer is divided by the vertical isolation plate, which effectively isolates diseases, prevents the spread of local infection, and ensures the overall planting success rate. An escape prevention layer is set in the planting layer to physically block the disorderly growth of Gastrodia elata tubers and rodent invasion, which significantly improves product quality and harvesting efficiency. The drainage layer at the bottom of the planting hole is combined with the water interception ditch to achieve precise water control while alleviating soil erosion on slopes, thus realizing the coordinated development of Gastrodia elata planting and ecological protection.

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] This utility model discloses a Gastrodia elata slope planting structure, including a slope body 1, a planting hole 2 formed by excavation at the slope position of the slope body 1, a base slope 201 with inward inclination at the bottom of the planting hole 2, and a water storage and drainage layer 3, an insect prevention layer 4, a planting layer 5 and a buffer layer 6 arranged in sequence from bottom to top in the planting hole 2. During the construction process, planting holes 2 are excavated at suitable slope locations on the main slope 1. At the bottom of the planting holes 2, a layer of oak wood 301 and a first layer of gravel 302 are set to form a water storage and drainage layer 3. Subsequently, an insect-proof layer 4 is set on top of the water storage and drainage layer 3 to effectively prevent pests from damaging Gastrodia elata. Then, a planting layer 5 is stacked on top of the insect-proof layer 4, and a vertical isolation board 8 is inserted into the planting layer 5 to divide the planting layer 5 into several independent planting modules, which can prevent the disorderly growth of Gastrodia elata tubers and resist the invasion of rodents. A buffer layer 6 is stacked on top of the planting layer 5 to play a buffering and protective role. An ecological protection layer 7 is set on top of the buffer layer 6 to promote the restoration and protection of the ecological environment.

[0021] In the technical solution of the drainage and water storage layer 3, the drainage and water storage layer 3 is composed of a layer of oak wood 301 and a first layer of crushed stone 302 stacked together. Specifically, the oak wood layer 301 is composed of several oak wood strips, and the arrangement direction of the oak wood strips is consistent with the slope inclination direction of the main slope 1. The first layer of crushed stone 302 is laid in the gap between two adjacent oak wood strips and at the bottom of the oak wood layer 301. The oak wood strips are arranged in the same direction as the slope inclination direction of the main slope 1, with appropriate gaps between adjacent oak wood strips, and the first layer of crushed stone 302 is laid in the gaps and at the bottom of the oak wood layer 301 to form a good drainage and water storage structure.

[0022] In the technical solution of the insect-proof layer 4, the insect-proof layer 4 includes a geotextile layer 401 and an insect repellent layer 402. The insect repellent layer 402 is laid on the upper surface of the geotextile layer 401. Specifically, the geotextile layer 401 is laid first on the drainage layer 3, and then the insect repellent layer 402 is evenly laid on the upper surface of the geotextile layer 401. The insect-proof layer 4 is a powdered diatomaceous earth layer, which effectively prevents pests from damaging Gastrodia elata.

[0023] In the technical solution of the planting layer 5, the planting layer 5 is stacked on the insecticide layer 402, and a vertical isolation plate 8 is inserted inside the planting layer 5 to divide the planting layer 5 into several independent planting modules. By dividing the planting layer 5 through the vertical isolation plate 8, diseases are effectively isolated, local infection spread is prevented, and the overall planting success rate is guaranteed. The vertical isolation plate 8 and the inner sidewall of the planting hole 2 are both fitted with an escape-proof liner 801. The escape-proof liner 801 is a microporous metal mesh. This microporous structure can ensure air permeability and effectively prevent the Gastrodia elata tubers from escaping from the planting module and prevent rodents from burrowing in and causing damage. The vertical height of the vertical isolation plate 8 is consistent with the thickness of the soil filling in the planting layer 5, ensuring that the planting layer 5 can be completely separated, providing a relatively independent and stable spatial environment for each planting module.

[0024] Furthermore, in the above scheme, the buffer layer 6 is formed by piling up pine needles and straw, and an ecological protection layer 7 is provided on top of the buffer layer 6. The ecological protection layer 7 includes the original topsoil of the slope and local herb seeds, and is backfilled and covered on the buffer layer 6. The ecological protection layer 7, including the original topsoil of the slope and local herb seeds, can promote the natural restoration of slope vegetation, provide a more stable and suitable ecological environment for the growth of Gastrodia elata, help enhance the soil and water conservation capacity of the slope, reduce the damage of rainwater erosion to the planting hole 2, and further ensure the growth safety of Gastrodia elata.

[0025] Furthermore, in the technical solution of the slope body 1, the slope surface of the slope body 1 is provided with a water interception ditch 9 above the planting hole 2. The water interception ditch 9 extends along the contour line of the slope surface, and a turf layer 901 and a second gravel layer 902 are provided in the water interception ditch 9 from top to bottom.

[0026] Furthermore, in the above scheme, an ecological bag retaining wall 11 is also built on the slope surface of the main slope 1 corresponding to the lower edge of the planting hole 2. The ecological bag retaining wall 11 is composed of several ecological bags filled with a mixture of soil and grass seeds stacked layer by layer, and the stacking method is a staggered triangular stacking.

[0027] It should be noted that a water interception ditch 9 is set above the planting hole 2 on the slope surface of the main body of the slope to further enhance the soil and water conservation capacity. An ecological bag retaining wall 11 is built on the lower edge of the planting hole 2 on the slope surface of the main body of the slope. The bag is stacked in a staggered pattern, which is both stable and conducive to the improvement of the ecological environment.

[0028] Furthermore, in the above scheme, a drainage pipe 10 is also provided in the planting hole 2. The drainage pipe 10 has several micropores in its wall. The drainage pipe 10 is buried at the bottom of the water storage and drainage layer 3, and its axis is parallel to the contour line. The two ends of the drainage pipe 10 extend and pass through the side wall of the planting hole 2. The drainage pipe 10 can optimize the water regulation in the planting hole 2. During periods of less rainfall, the micropores in the wall of the drainage pipe 10 allow water to slowly infiltrate, ensuring adequate moisture in the soil of the planting hole 2 and avoiding water accumulation caused by excessive moisture. Furthermore, the diversion pipe 10 is buried at the bottom of the water storage and drainage layer 3, and the axis of the diversion pipe 10 is parallel to the contour line. Both ends of the diversion pipe 10 extend and pass through the side wall of the planting hole 2, so that water can flow naturally along the slope, reducing the risk of soil erosion and further improving the stability and soil and water conservation capacity of the planting hole 2.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
