Description

Technical Field

[0001] This invention relates to the field of Gastrodia elata cultivation equipment, specifically a method and apparatus for planting Gastrodia elata using giant reed grass instead of firewood. Background Technology

[0002] Gastrodia elata relies on Armillaria mellea for nutrition, which in turn is nutrient-rich from firewood. It doesn't need to absorb nutrients from the soil; the soil only serves as a substrate for fixation and covering. Current planting methods involve planting on level ground, cutting giant Napier grass (2-6cm in diameter) into 15cm sections. The soil is loosened and leveled in the field. Giant Napier grass sections are arranged at 1.2cm intervals, with a 1.2m gap on each side for drainage ditches and access paths. The thickness of the giant Napier grass sections doesn't matter; a thickness of 15cm is sufficient. A 5cm gap is left between each row of sections to create a cluster of Armillaria mellea spawn, continuing this arrangement to the edge of the field. Then, each 1.1kg bag of Armillaria mellea spawn is evenly cut three times, breaking it into four round cakes (each about 5cm thick). Each cake is broken in half and placed in the gaps left in the giant Napier grass. Digging during the harvesting of Gastrodia elata causes severe damage to the plant and further damages the surface vegetation. Therefore, it is necessary to use planting boxes to cultivate Gastrodia elata.

[0003] According to the patent document CN108782088A, a gastrodia elata cultivation device and its method for cultivating gastrodia elata are disclosed. The device includes a square box with a sliding plate inside. A circular through-hole is located in the center of the sliding plate, and a circular turntable is rotatably connected to the through-hole. Four grooves are evenly distributed around the center of the turntable. A disc is mounted on the turntable, and protrusions corresponding to the grooves are provided on the disc. A receiving plate is located below the disc, and three connecting rods are provided between the disc and the receiving plate. This technical solution uses a mixture of sand and giant reed leaves to cultivate gastrodia elata. The giant reed leaves are relatively loose compared to the soil, eliminating the need for hoes during harvesting and avoiding damage to the gastrodia elata from digging devices, thus reducing labor intensity. However, while this solution avoids damage from digging, it cannot simultaneously fix the substrate and control the ventilation gaps, resulting in inconvenience during use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a method and apparatus for planting Gastrodia elata using giant reed grass instead of firewood, thereby solving the problems mentioned in the background art. The present invention has a novel structure. In use, the height of the fixing frame inside the planting box is adjusted by moving the cover plate up and down. Later, the fixing frame moves down to clamp and fix the fungal material. In addition, the upward movement of the cover plate enables rapid opening, and the cover plate opens to a certain width under the support of the threaded seat and threaded tube to achieve ventilation inside the box.

[0005] To achieve the above objectives, the present invention provides a method for cultivating Gastrodia elata using giant reed grass instead of firewood, the cultivation method comprising the following steps: Step 1: Location selection; Select a plot of land in the mountains with an altitude between 600 and 1800 meters, with loose, well-aerated, and well-drained soil, and with 45% shade from the trees on the ground. Simply loosen the soil and level it. Step 2: Preparation of fungal materials; Harvest the mature giant reed grass and bring it to the field. Cut the grass stalks into 15cm pieces for later use, and cut the grass leaves into 7cm pieces for later use.

[0006] Step 3: Planting Gastrodia elata; Cut giant Napier grass (2-6cm in diameter) into 15cm sections. Loosen and level the soil in the field; arrange the giant Napier grass sections 1.2cm apart, leaving a 1.2m gap on each side for drainage ditches and access roads. The thickness of the giant Napier grass sections doesn't matter, just arrange them neatly to a thickness of 15cm; leave a 5cm gap between each row of giant Napier grass sections to accommodate Armillaria mellea spawn, continuing this arrangement to the edge of the field. Then, evenly cut each bag of Armillaria mellea spawn (1.1kg) three times, breaking it into four round cakes (each cake approximately 5cm thick), and break each cake in half, placing them in the gaps left in the giant Napier grass.

[0007] The planting layer, consisting of sandy soil and giant reed leaves, is laid inside the planting device. The fungal material and Gastrodia elata seeds are then placed inside the planting device for planting.

[0008] Step 4: Bury the planting box; Backfill the gaps around the planting box with soil and compact the soil firmly. Cover the part of the planting box side wall that protrudes above the ground with soil as well.

[0009] Step 5: Harvesting Gastrodia elata.

[0010] Furthermore, in step two, the giant Napier grass with a diameter of 2-6cm is cut into 15cm segments. The soil in the field is loosened and leveled; the giant Napier grass segments are arranged at 1.2cm intervals, with 1.2cm intervals on each side serving as drainage ditches and work paths. The thickness of the giant Napier grass segments is not important; they should be neatly arranged with a thickness of 15cm. A 5cm gap is left between each row of giant Napier grass segments to preserve Armillaria mellea clumps, continuing forward to the edge of the field. Then, the Armillaria mellea spawn (1.1kg per bag) is evenly cut three times at intervals, breaking it into four round cakes (each cake approximately 5cm thick). Each cake is broken in half and placed in the reserved gaps in the giant Napier grass. In step five, when the Gastrodia elata matures, it is removed from the planting device, and the mixed sand and giant Napier grass leaves are removed, ensuring the integrity of the substrate and avoiding contact with the planting device. New mixed sand, giant Napier grass leaves, and Gastrodia elata seeds are then laid around the substrate, and the Gastrodia elata is planted again.

[0011] A method for cultivating Gastrodia elata using giant reed grass as a substitute for firewood includes a cultivation device comprising a box body. A cover plate is movably installed on the top of the box body, and a reinforcing plate is fixed to the side of the box body. A movable seat is movably installed at the bottom of the reinforcing plate. The movable seat is limited and installed on the box body by fixing bolts. A cutting is welded to the bottom of the movable seat. A handle is fixed to the top of the cover plate, and an opening is formed on the side of the box body.

[0012] Furthermore, the box body has a U-shaped groove, a fixed tube is movably installed inside the U-shaped groove, a rotating tube is rotatably installed on the fixed tube, and both the rotating tube and the fixed tube have grooves.

[0013] Furthermore, a rotating seat is rotatably mounted on the inner wall of the cover plate, a positioning post is fixed on the rotating seat, a positioning tube is movably mounted on the positioning post, one end of the positioning tube is fixed inside the box, and an opening is opened on the positioning tube.

[0014] Furthermore, protrusions and mounting tubes are fixed on both sides of the positioning post, the protrusions and mounting tubes are movably installed inside the opening, a water-absorbing rope is fixedly installed between the protrusions and the mounting tubes, and a support tube is fixed on the inner wall of the cover plate.

[0015] Furthermore, a connecting column is movably installed inside the support tube, a fixing frame is fixed to one end of the connecting column, a planting box is movably installed on the fixing frame, the planting box is fixed between the installation tubes, a fixing plate is fixed to the top of the planting box, a fixing groove is opened inside the fixing frame, and the fixing plate is movably installed inside the fixing groove.

[0016] Furthermore, a baffle is welded onto the connecting column, a threaded seat is fixed on the inner wall of the support tube, a threaded tube is fixed to one end of the connecting column, the threaded seat is rotatably mounted on the threaded tube, a through hole is opened at the bottom of the planting box, a planting layer is installed inside the planting box, and fungal material is installed between the planting layer and the fixing frame.

[0017] Furthermore, a reset mechanism is fixed to one end of the connecting column, a bearing seat is fixed to one end of the reset mechanism, a support plate is fixed to the bearing seat, and the support plate is fixed inside the support tube.

[0018] The beneficial effects of this invention are: 1. In use, the cover plate moves up and down to adjust the height of the fixing frame inside the planting box. Later, the fixing frame moves down to clamp and fix the fungal material. In addition, the cover plate moves up to open quickly, and the cover plate opens to a certain width under the support of the threaded seat and threaded tube to achieve the ventilation effect inside the box.

[0019] 2. In this invention, the positioning post is installed inside the positioning tube by means of a protrusion and an installation tube. After the protrusion is installed inside the positioning tube, it drives the water-absorbing rope into the positioning tube. The water-absorbing rope is installed inside the fixed tube by means of a slot, so that water can be introduced into the planting layer through the water-absorbing rope later to keep the planting layer moist. The water-absorbing rope can guide water to avoid water loss from the planting layer during irrigation. The rotating tube can limit and fix the water-absorbing rope by rotating on the fixed tube.

[0020] 3. In this embodiment, the box body increases the contact points with the pit through the reinforcing plate to prevent the box body from shaking. In addition, the reinforcing plate provides a support point for the movable seat. The support seat is limited under the support of the reinforcing plate. By pressing the box body, the insertion at the bottom of the movable seat is fixed to the ground. The movable seat can fix the box body and can also cover and seal the opening. The opening can achieve water drainage and prevent damage to the Gastrodia elata due to excessive rainwater inside the box body. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 and Figure 2 This invention provides a technical solution: a method for cultivating Gastrodia elata using giant reed grass as a substitute for firewood, the cultivation method comprising the following steps: Step 1: Location selection; Select a plot of land in a mountainous area with an altitude between 600 and 1800 meters, with loose, well-aerated, and well-drained soil, and with 45% shade from trees on the ground. Loosen and level the land.

[0024] Step 2: Preparation of fungal materials; Harvest the mature giant reed grass and bring it to the field. Cut the grass stalks into 15cm pieces for later use, and cut the grass leaves into 7cm pieces for later use.

[0025] Step 3: Planting Gastrodia elata; Cut giant Napier grass (2-6cm in diameter) into 15cm sections. Loosen and level the soil in the field; arrange the giant Napier grass sections 1.2cm apart, leaving a 1.2m gap on each side for drainage ditches and access roads. The thickness of the giant Napier grass sections doesn't matter, just arrange them neatly to a thickness of 15cm; leave a 5cm gap between each row of giant Napier grass sections to accommodate Armillaria mellea mycelium clumps, continuing this arrangement to the edge of the field. Then, evenly cut each bag of Armillaria mellea spawn (1.1kg) three times, breaking it into four round cakes (each cake approximately 5cm thick), and break each cake in half, placing them in the gaps left in the giant Napier grass. Lay the planting layer inside the planting device; the planting layer consists of sandy soil and giant Napier grass leaves. Place the mycelium and Gastrodia elata seeds inside the planting device for planting.

[0026] Step 4: Bury the planting box; Backfill the gaps around the planting box with soil and compact the soil firmly. Cover the part of the planting box side wall that protrudes above the ground with soil as well.

[0027] Step 5: Harvesting Gastrodia elata.

[0028] In this embodiment, in step two, giant Napier grass with a diameter of 2-6cm is cut into 15cm segments. The soil in the field is loosened and leveled; the giant Napier grass segments are arranged at 1.2cm intervals, with 1.2cm intervals on both sides serving as drainage ditches and work paths. The thickness of the giant Napier grass segments is not important; they should be neatly arranged with a thickness of 15cm. A 5cm gap is left between each row of giant Napier grass segments to preserve Armillaria mellea clumps, continuing forward to the edge of the field. Then, the Armillaria mellea spawn (1.1kg per bag) is evenly cut three times at intervals, breaking it into four round cakes (each cake approximately 5cm thick). Each cake is broken in half and placed in the reserved gaps in the giant Napier grass. In step five, when the Gastrodia elata matures, it is removed from the planting device, and the mixed sand and giant Napier grass leaves are removed, ensuring the integrity of the substrate and avoiding contact with the planting device. New mixed sand, giant Napier grass leaves, and Gastrodia elata seeds are then laid around the substrate, and the Gastrodia elata is planted again.

[0029] A method for cultivating Gastrodia elata using giant reed grass as a substitute for firewood includes a cultivation device comprising a box 1. A cover plate 2 is movably mounted on the top of the box 1. A reinforcing plate 3 is fixed to the side of the box 1. A movable seat 4 is movably mounted on the bottom of the reinforcing plate 3. The movable seat 4 is fixedly mounted on the box 1 by fixing bolts 6. A cutting 7 is welded to the bottom of the movable seat 4. A handle 8 is fixed to the top of the cover plate 2. An opening 5 is formed on the side of the box 1. The movable seat 4 is fixedly positioned on the box 1 by the fixing bolts 6. The fixed position is adjusted. The movable seat 4 seals the opening 5 to control the rate of moisture release, thereby effectively maintaining the moisture content of the box 1.

[0030] In this embodiment, the housing 1 has a U-shaped groove 9, and a fixed tube 10 is movably installed inside the U-shaped groove 9. A rotating tube 11 is rotatably installed on the fixed tube 10. Both the rotating tube 11 and the fixed tube 10 have slots 12. A rotating seat 23 is rotatably installed on the inner wall of the cover plate 2. A positioning post 13 is fixed on the rotating seat 23. A positioning tube 15 is movably installed on the positioning post 13. One end of the positioning tube 15 is fixed inside the housing 1. An opening 16 is opened on the positioning tube 15. A protrusion 20 and an installation tube 22 are fixed on both sides of the column 13 respectively. The protrusion 20 and the installation tube 22 are movably installed inside the opening 16. A water-absorbing rope 21 is fixedly installed between the protrusion 20 and the installation tube 22. A support tube 14 is fixed on the inner wall of the cover plate 2. The water-absorbing rope 21 is in contact with the external water source. The water-absorbing rope 21 is made of pure cotton. Through the principle of cotton thread absorbing and guiding water, the external water is guided into the planting layer 27 to provide a suitable water source for the growth of Gastrodia elata, thereby avoiding the loss caused by the impact of spraying on the planting layer 27.

[0031] In this embodiment, a connecting column 17 is movably installed inside the support tube 14. A fixing frame 18 is fixed to one end of the connecting column 17. A planting box 19 is movably installed on the fixing frame 18. The planting box 19 is fixed between the mounting tubes 22. A fixing plate 25 is fixed to the top of the planting box 19. A fixing groove 24 is opened inside the fixing frame 18. The fixing plate 25 is movably installed inside the fixing groove 24. A baffle 29 is welded onto the connecting column 17. A threaded seat 30 is fixed to the inner wall of the support tube 14. A threaded tube 31 is fixed to one end of the connecting column 17. The threaded seat 30 is rotatably installed on the threaded tube 31. A through hole 2 is opened at the bottom of the planting box 19. 6. The planting box 19 is equipped with a planting layer 27. The planting layer 27 and the fixing frame 18 are equipped with fungal material 28. One end of the connecting column 17 is fixed with a reset mechanism 32. One end of the reset mechanism 32 is fixed with a bearing seat 33. A support plate 34 is fixed on the bearing seat 33. The support plate 34 is fixed inside the support tube 14. The reset mechanism 32 is a reset spring. The reset spring drives the cover plate 2 to move downward. When the cover plate 2 is opened to observe the inside of the box 1 later, the cover plate 2 drives the support tube 14 to move upward and stretch the reset mechanism 32. After the reset mechanism 32 is stretched, it generates a rebound force. After the cover plate 2 is released, the reset mechanism 32 drives the cover plate 2 to contact the box 1 for sealing.

[0032] Working principle: When using this device, the handle 8 first moves the cover plate 2 upward. The upward movement of the cover plate 2 causes the positioning column 13 to remove the planting box 19 from the inside of the box body 1. After the planting box 19 is removed, a layer of mixed sand and giant Napier grass leaves is spread on the planting box 19. The mixed sand and giant Napier grass leaves are made by mixing sand and giant Napier grass leaves in a 1:4 ratio and then spraying water. Then, giant Napier grass stalks 28 are evenly spread on top. The giant Napier grass stalks 28 are installed at the bottom of the fixing frame 18. Later, the thrust generated by the reset mechanism 32 causes the fixing frame 18 to descend and complete the clamping of the fungal material 28. Limiting the position, evenly spread Gastrodia elata seeds around the giant Napier grass stalk 28, and install the planting box 19 inside the box body 1. During installation, the positioning post 13 is positioned inside the opening 16 via the protrusion 20 and the installation tube 22. The positioning post 13 moves inside the positioning tube 15. When the positioning post 13 moves, the protrusion 20 drives the water-absorbing rope 21 to move inside the fixing tube 10 and the positioning tube 15. Leaves can be added to the sides of the planting box 19 and the inside of the box body 1. After the planting box 19 is installed in its correct position, the box body 1 is then installed on a leveled plot of land. 1. During installation, the position of the movable seat 4 is controlled by the fixing bolt 6. The movement of the movable seat 4 controls the usage state of the opening 5. After the box 1 is installed in the planting hole, the reinforcing plate 3 pushes the cutting 7 on the movable seat 4 downward. The cutting 7 is inserted into the ground to provide support and fixation for the box 1. During use, the handle 8 drives the cover plate 2 upward. When the cover plate 2 moves upward, the reset mechanism 32 pulls and deforms. When one end of the threaded seat 30 and the threaded tube 31 contacts, it is limited. After the limit is reached, the cover plate 2 opens to a certain angle to facilitate observation of the inside of the box 1. When it is necessary to ventilate... When the wind blows, the handle 8 drives the cover plate 2 to rotate, and the support tube 14 drives the threaded tube 31 to rotate on the threaded seat 20. The rotation adjusts the gap between the cover plate 2 and the box 1. Different gaps complete the ventilation treatment under different conditions. The water-absorbing rope 21 is installed inside the fixed tube 10 through the slot 12, which facilitates the later introduction of water into the planting layer 27 through the water-absorbing rope 21 to keep the planting layer 27 moist. The water-absorbing rope 21 is used to guide water and avoid water loss from the planting layer 27 during irrigation. The rotating tube 11 can limit and fix the water-absorbing rope 21 by rotating on the fixed tube 10.
