Description

Technical Field

[0001] This invention relates to the field of Gastrodia elata cultivation technology, specifically to a fixed-bed double-layer Gastrodia elata cultivation device and cultivation method. Background Technology

[0002] Gastrodia elata is a perennial saprophytic herb of the Orchidaceae family. It has no roots or leaves and obtains nutrients through symbiosis with Armillaria mellea. As a plant with both medicinal and edible uses, its cultivation requires the use of alternating layers of wood and Armillaria mellea substrate to form a mycelial bed for the growth of seeds or seed tubers. In practice, it is crucial to ensure the quality of mycelial growth on the wood. Current fixed-bed double-layer cultivation devices are not ideal for separately cultivating seeds and seed tubers in two layers. The traditional method of cultivating seed tubers on top of the wood results in low utilization of the space below, increasing costs and causing unnecessary waste. Furthermore, it hinders soil aeration and water permeability, increasing the risk of root rot and hindering automatic waterlogging prevention, especially in the early stages of cultivation, which directly impacts growth and further increases the risk of root rot.

[0003] Therefore, we propose a fixed-bed double-layer Gastrodia elata cultivation device and cultivation method. Summary of the Invention

[0014] A method for cultivating Gastrodia elata in a fixed mycelium bed with two layers:

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention utilizes a cultivation installation component to position the stump-shaped mycelium substrate, facilitating its full utilization. Gastrodia elata seeds are cultivated beneath the substrate, avoiding the pitfalls of traditional Gastrodia elata cultivation methods. Traditionally, the area beneath the substrate is far from the soil layer, resulting in poor aeration and wasting wood, increasing costs, and being environmentally unfriendly. The substrate positioning bolts can position a row of stump-shaped mycelium substrates, ensuring that seed blocks or already grown Gastrodia elata are easily accessible. This provides greater flexibility. Combined with a one-way isolation component, it adapts to soil compaction caused by watering and other factors. As the soil compacts and its thickness decreases, this structure maintains constant contact between the soil and the substrate, ensuring the mycelium remains in contact with the Gastrodia elata. The structure is more rational, and the one-way isolation component also isolates the soil used for cultivating Gastrodia elata seeds, facilitating separate collection.

[0019] Using loose reminders can help staff keep the soil under the isolation board loose during the cultivation of Gastrodia elata, which can make the soil more breathable and permeable, especially in the early stage of cultivation, and reduce the rate of root rot.

[0020] The use of water-proof control components facilitates rain protection for Gastrodia elata. At the same time, this structure can automatically detect rainfall and automatically control the sealing of the isolation plate, which allows water under the isolation plate to seep downwards. Especially for rainfall, it can prevent problems such as root rot caused by excessive rain. It also makes it easier to manually replenish water in a quantitative manner, ensuring the growth quality of Gastrodia elata and avoiding the problem of rainwater seeping from the ground that can occur with traditional rain covers.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 10 As shown:

[0034] This invention provides a technical solution: a fixed-bed double-layer Gastrodia elata cultivation device, including a cultivation installation component 1, which is used for double-layer cultivation of Gastrodia elata; a one-way isolation component 2 is installed on the cultivation installation component 1; a limit release component 3 is installed on the cultivation installation component 1; a loose soil indicator 4 is installed at the bottom of the cultivation installation component 1; the loose soil indicator 4 is used to detect the looseness of the soil during cultivation; a tilt control component 5 is installed at the top of the cultivation installation component 1; the tilt control component 5 is used to block water; a water-blocking control component 6 is installed inside the one-way isolation component 2; the water-blocking control component 6 is used to promote the downward penetration of water; the cultivation installation component 1 includes: a cultivation installation frame 101 and an indicator light 102, the indicator light 102 is fixedly installed on the side of the cultivation installation frame 101; the cultivation installation frame 101 is used to be placed on a slope; the cultivation installation frame 101 has four rows of serrated grooves inside.

[0035] The cultivation installation component 1 further includes: a support plate 103 and substrate positioning bolts 104. Two support plates 103 are rotatably installed on both sides of the cultivation installation frame 101. The two support plates 103 are used to support the cultivation installation frame 101. Two rows of substrate positioning bolts 104 are threaded onto the cultivation installation frame 101, and the two rows of substrate positioning bolts 104 pass through the cultivation installation frame 101. The ends of the two rows of substrate positioning bolts 104 are respectively provided with pointed heads, and the two rows of substrate positioning bolts 104 are used to position the substrate of the wood stump mushroom bed. The isolation component 2 includes: an isolation plate 201, inclined block 2011, limiting spring 202, one-way limiting block 203, and isolation net 204. Four inclined blocks 2011 are fixedly installed on the isolation plate 201. The isolation plate 201 is slidably fitted inside the cultivation installation frame 101. The four inclined blocks 2011 are respectively aligned with the four rows of ratchet grooves opened inside the cultivation installation frame 101. Four limiting springs 202 are fixedly installed on the 01, and the four limiting springs 202 are V-shaped structures; four one-way limiting blocks 203 are slidably inserted into the isolation plate 201, and each of the four one-way limiting blocks 203 is provided with a ratchet tooth. The four one-way limiting blocks 203 are respectively inserted into four rows of ratchet grooves opened inside the cultivation installation frame 101; the four one-way limiting blocks 203 are respectively connected to the ends of the four limiting springs 202; a row of A through groove; an isolation net 204 is fixedly installed on the isolation plate 201; the limit release component 3 includes: a push slider 301 and a compression bolt 302; four push sliders 301 are slidably inserted into the cultivation installation frame 101, and the four push sliders 301 pass through the cultivation installation frame 101 respectively; the four push sliders 301 are respectively aligned with the four rows of ratchet grooves opened inside the cultivation installation frame 101; the four push sliders 301 are respectively used to compress the four unidirectional limit blocks 203 inward;The cultivation installation frame 101 is threaded with four compression bolts 302, and the ends of the four compression bolts 302 are respectively aligned with four push sliders 301. The cultivation installation component 1 can be used to position the stump-shaped substrate, facilitating full utilization of the substrate. Cultivating Gastrodia elata seeds below the substrate has minimal impact on their growth and expansion, and requires less aeration, allowing for deeper planting. The area beneath the wood provides stable humidity and shade, which is beneficial for the germination fungi to decompose the leaves and release nutrients. The Gastrodia elata seed blocks, which are the thumb-sized seed blocks after the seeds have grown, are cultivated above the substrate. This method fully utilizes the timber stump substrate, avoiding the pitfalls of traditional Gastrodia elata cultivation. Traditionally, timber stump substrates are not used for cultivation due to their distance from the soil layer and poor aeration, resulting in waste, increased wood consumption, environmental concerns, and higher costs. This structure uses 104 positioning bolts to position a row of timber stump substrates, ensuring that seed blocks for seed cultivation or already grown hemp can be easily accessed. This offers greater flexibility. Cultivating both Gastrodia elata seeds and finished hemp requires wood and Armillaria mellea, just like cultivating commercial hemp. Having the same common characteristics, they can grow together and be fully utilized. Simultaneously, with the unidirectional isolation element 2, unidirectional movement can be achieved. When filling the soil substrate on top of the unidirectional isolation element 2 for Gastrodia elata seeds, the unidirectional isolation element 2 can adapt to the gradual compaction of the soil due to watering and other factors. As the soil compacts and its thickness decreases, this structure can maintain real-time contact between the soil and the wooden stump substrate, ensuring real-time contact between the mycelium and the Gastrodia elata. The structure is more rational. At the same time, the unidirectional isolation element 2 can isolate the cultivation soil for Gastrodia elata seeds, facilitating separate collection without manual digging, thus maintaining the quality of the cultivation soil. As the soil on the isolation plate 201 gradually compacts and its thickness decreases, the cultivation installation frame 101 can fall under its own weight and the gravity of the soil above the stump substrate. At this point, the isolation plate 201 remains on the soil surface below, its position unchanged. In other words, the cultivation installation frame 101 moves up and down on the isolation plate 201. During this process, the one-way limiting block 203 slides within the four rows of ratchet grooves inside the cultivation installation frame 101 under the elastic compression of the limiting spring 202, providing one-way limiting. Subsequently, the cultivation installation frame 101 can be directly lifted, and the internal soil can be easily collected separately.

[0036] The loosening indicator 4 includes: two conveyor plates 401, which are slidably inserted into the bottom of the cultivation installation frame 101; springs are fixedly installed on the top of each of the two conveyor plates 401, and the ends of the springs on the top of the conveyor plates 401 are fixedly connected to the inside of the cultivation installation frame 101; the bottom of the conveyor plates 401 has a sloping structure; the top side of the conveyor plates 401 has a sloping structure; the loosening indicator 4 also includes: a detection switch 402, which is fixedly installed on the side of the cultivation installation frame 101, and the end of the detection switch 402 passes through the cultivation installation frame 101. 1; The top side slope of the conveyor plate 401 is used for the squeeze detection switch 402; The detection switch 402 is electrically connected to the indicator light 102. The use of the loose indicator 4 can help remind workers to keep the soil below the isolation plate 201 loose during the cultivation of Gastrodia elata, which can facilitate soil aeration and water permeability, especially in the early stage of cultivation. It also makes it easier for the cultivation installation frame 101 to descend into the loose soil under its own weight when the soil above the isolation plate 201 becomes compacted after the subsequent cultivation installation frame 101 is placed in the soil below, so that the cultivation installation frame 101 has room to descend in the loose soil when it is reduced in the later stage, making the structure more reasonable.

[0037] In Example 2, based on Example 1, the tilt control component 5 includes: a rain cover 501 and a collection box 502. The rain cover 501 is fixedly installed on the top of the cultivation installation frame 101 by bolts; the rain cover 501 is made of transparent material; the side of the rain cover 501 has a ventilation opening; the collection box 502 is fixedly installed on the top of the rain cover 501; the ventilation opening on the side of the rain cover 501 is located at the lower part of the planting slope; the tilt control component 5 also includes: a float 503, a contact plate 504, and a contact spring 505, and the collection box 502... 2. A float 503 is placed inside; a contact plate 504 is fixedly installed on the top of the float 503; two contact springs 505 are fixedly installed inside the collection box 502, and the two contact springs 505 are aligned with the contact plate 504; the water-blocking control component 6 includes: a water-blocking baffle 601, a tension spring 6011 and an electromagnet 602, the water-blocking baffle 601 is slidably inserted into the isolation plate 201; the water-blocking baffle 601 is provided with a row of through slots; the intervals of the row of through slots on the water-blocking baffle 601 are used to block the row of through slots at the bottom of the isolation plate 201. A through groove; a tension spring 6011 is fixedly installed on the side of the water-blocking baffle 601, and the other end of the tension spring 6011 is fixedly connected to the inside of the isolation plate 201; an electromagnet 602 is fixedly installed inside the isolation plate 201; the electromagnet 602 and two contact springs 505 are connected in series with a power supply; the electromagnet 602 is used to magnetically attract the water-blocking baffle 601. The use of the water-blocking control component 6 facilitates the protection of Gastrodia elata from rain. At the same time, this structure can automatically detect rainfall and automatically control the closure of the isolation plate 201, which can facilitate the isolation plate 201. Water seeps downwards from below 01, especially during rainfall, which can prevent root rot caused by excessive rainwater. It also makes it easier to add water manually in a measured amount, ensuring the growth quality of Gastrodia elata. It avoids the problem of rainwater seeping from the ground that can occur with traditional rain covers. The ventilation opening on the rain cover 501 is located at the low point of the planting slope, maintaining air permeability and preventing rainwater from entering. During rainfall, the slots on the water-proof baffle 601 and the isolation plate 201 are automatically misaligned to achieve sealing and promote the downward seepage of water from the outside of the isolation plate 201.

[0038] A method for cultivating Gastrodia elata in a fixed mycelium bed with two layers:

[0039] 1) Place the cultivation installation frame 101 on the ground, bury the top of the cultivation installation frame 101 with soil, and place the ventilation opening on the rain cover 501 at the low point of the planting slope.

[0040] 2) Lay sawdust on the isolation net 204, then lay a layer of soil and leaves, scatter Gastrodia elata seeds, place a row of Armillaria mellea cultured wooden stake substrate on top of the Gastrodia elata seeds and leaves, rotate the substrate positioning bolt 104 to press and position, place Gastrodia elata seed blocks on top of the row of Armillaria mellea cultured wooden stake substrate and at both ends, and finally cover with soil.

[0041] The working principle of this embodiment is as follows: First, place the cultivation installation frame 101 on the ground, burying the top of the frame with soil, leaving the rain cover 501 exposed. The ventilation opening on the rain cover 501 is located at the lower part of the planting slope to maintain ventilation and prevent rainwater from entering. In actual cultivation, first lay sawdust on the isolation net 204, then lay a layer of soil and leaves, and then sow the Gastrodia elata seeds. At this time, place a row of Armillaria mellea-cultured wood stump substrate on top of the Gastrodia elata seeds and leaves, and press and position it by rotating the substrate positioning bolts 104. Then, place Gastrodia elata seed blocks on top of the row of Armillaria mellea-cultured wood stump substrate and at both ends, and finally cover with soil. Subsequent plantings will proceed as the seeds... As the soil on the isolation plate 201 gradually compacts and its thickness decreases, the cultivation installation frame 101 can fall under its own weight and the gravity of the soil above the stump substrate. At this point, the isolation plate 201 remains on the soil surface below, its position unchanged. The cultivation installation frame 101 moves downwards on the isolation plate 201. During this process, the one-way limiting block 203 slides within the four rows of ratchet grooves inside the cultivation installation frame 101 under the elastic compression of the limiting spring 202. When it is necessary to remove the seed blocks after seed growth, the cultivation installation frame 101 can be lifted directly, and the two support plates 103 can be flipped downwards for ground support. At this time, the one-way limiting block 203... 03 is stuck in the four rows of ratchet grooves inside the cultivation installation frame 101. A box larger than the isolation plate 201 can be placed under the isolation plate 201 or directly placed in the tractor bed for support. The four compression bolts 302 can be rotated to compress the push slider 301 and the one-way limiting block 203, causing the ratchet teeth on the one-way limiting block 203 to disengage from the four rows of ratchet grooves inside the cultivation installation frame 101, thus releasing the limit. At this time, the seed blocks cultivated under the stump substrate can fall off. The stump substrate, which is positioned and clamped, can isolate the finished hemp cultivated from the Gastrodia elata seed blocks above, thus achieving isolation. The finished hemp cultivated from the Gastrodia elata seed blocks above can be manually isolated. The seed can be harvested or left on the ground. Soil can be filled on top of the isolation plate 201 for seed cultivation. When the cultivation installation frame 101 is placed on the ground, if the ground soil has been loosened, the conveying plate 401 can be directly inserted into the soil. Otherwise, if the soil has not been loosened beforehand, the soil hardness is high. When the conveying plate 401 is placed on the ground, it is stopped by the ground under the weight of the cultivation installation frame 101, compressing the spring above the conveying plate 401. As the cultivation installation frame 101 is pressed down, the detection switch 402 moves down and is squeezed by the side of the conveying plate 401, which illuminates the control indicator light 102 to remind the staff to loosen the soil first.

[0042] During rainfall, rainwater is collected through collection box 502. The buoyancy of the rainwater causes float 503 to move upward, and conduction is achieved by the contact piece 504 abutting two contact springs 505. This controls the electromagnet 602 to electromagnetically attract the water-blocking baffle 601, causing the water-blocking baffle 601 to move and lengthen the tension spring 6011. As the water-blocking baffle 601 moves, the through grooves on the water-blocking baffle 601 and the through grooves on the isolation plate 201 are misaligned, achieving a seal. This promotes the downward permeation of water from the outside of the isolation plate 201, maintaining the growth environment of Gastrodia elata. As the rain stops and the rainwater inside collection box 502 evaporates, float 503 falls, electromagnet 602 is de-energized, and water-blocking baffle 601 automatically resets, maintaining the air permeability of the isolation plate 201.
