Description

Technical Field

[0001] This invention belongs to the field of Gastrodia elata cultivation technology, specifically relating to a method for intensive cultivation of Gastrodia elata in a factory. Background Technology

[0002] Gastrodia elata is a crop with high medicinal value, and its market demand continues to grow. However, traditional cultivation methods are inefficient, and inconsistent planting standards have become major obstacles to high-quality, standardized, and large-scale production. Gastrodia elata relies on an obligate symbiotic relationship with germinating fungi and Armillaria mellea to complete its growth cycle; its yield and quality directly depend on the quality of the seed source, the stability of the symbiotic system, and the level of control over the growth environment. With the depletion of wild Gastrodia elata resources, artificial cultivation has become the main support for market supply, and intensive factory cultivation, which can overcome natural environmental limitations and achieve standardized production, has become an important direction for industrial upgrading. Current intensive indoor cultivation of Gastrodia elata largely focuses on transferring the traditional, spread-out cultivation method dependent on natural conditions to greenhouses, fully utilizing space to create a three-dimensional planting model. This facilitates unified control of the planting environment and increases the arable area, thereby improving the yield of Gastrodia elata. However, besides spatial breakthroughs, the current indoor intensive cultivation approach still relies on the symbiotic relationship between Gastrodia elata and Armillaria mellea, essentially planting them in the same pond as outdoors. This method requires pre-planting of Armillaria mellea. The cultivation of Armillaria mellea mycelium is followed by the transfer of the cultured Armillaria mellea mycelium to planting ponds or baskets for co-planting with Gastrodia elata. Since the Armillaria mellea mycelium is usually unusable after one harvest of Gastrodia elata, this method of cultivation followed by transfer prolongs the cultivation cycle of Gastrodia elata. Furthermore, planting Armillaria mellea and Gastrodia elata in the same pond or basket makes it impossible to observe the invasion and fusion between the Armillaria mellea mycelium and the Gastrodia elata tuber, and to monitor and intervene in the growth of the Armillaria mellea mycelium. Poor growth of the Armillaria mellea mycelium and poor invasion and fusion with the Gastrodia elata tuber directly affect the growth of Gastrodia elata. Summary of the Invention

[0003] This invention provides a method for intensive cultivation of Gastrodia elata in a factory. Utilizing the upper space, a three-dimensional cultivation model is employed. Unlike existing intensive cultivation structures, this invention uses staggered planting of Gastrodia elata and Armillaria mellea in a vertical direction. The Armillaria mellea cultivation layer is located below the Gastrodia elata planting layer. After the Armillaria mellea mycelium grows upwards, it touches the upper layer of Gastrodia elata tubers, achieving invasion and fusion, thus providing nutrients for the growth of Gastrodia elata. This cultivation method solves the problems of traditional methods where Armillaria mellea mycelium needs to be planted in the same pond or basket as Gastrodia elata seeds, requiring transplantation of the mycelium and making it impossible to directly monitor and intervene in the growth of Armillaria mellea mycelium and its invasion and fusion with the Gastrodia elata seeds, thus failing to directly intervene and control the growth of Gastrodia elata from the source.

[0004] To achieve the above-mentioned technical objectives, the present invention is implemented through the following technical solution: A method for intensive industrial cultivation of Gastrodia elata includes the following steps: S1: Three-dimensional planting zone, the three-dimensional planting rack is set with 7 to 9 layers, the bottom layer is set as the water and fertilizer collection layer, and the other layers are set as staggered areas for Gastrodia elata planting and Armillaria mellea cultivation. S2: Set up planting baskets and Armillaria mellea culture bags, and arrange them in the following order from the top of the three-dimensional planting rack: upper layer of Gastrodia elata planting layer and lower layer of Armillaria mellea culture bag; planting baskets are set on the Gastrodia elata planting layer and Armillaria mellea culture bags are set on the Armillaria mellea culture bag; S3: Mycelium culture, the area around the planting rack of the Armillaria mellea culture layer is shielded from direct sunlight, allowing only weak, diffused light to pass through; S4: Planting Gastrodia elata seeds. Lay a layer of sawdust and wood chips mixture at the bottom of the planting basket, then place the Gastrodia elata seeds on the sawdust and wood chips mixture; then cover the Gastrodia elata seeds with substrate; and shield the planting layer from direct sunlight. S5: Temperature and humidity control. Separate temperature and humidity control methods are used for the Armillaria mellea culture layer and the Gastrodia elata planting layer. The temperature of the Armillaria mellea culture layer is controlled at 22~25℃ and the humidity is controlled at 65%~70%. The temperature of the Gastrodia elata planting layer is controlled at 15~25℃ and the humidity is controlled at 70%~90%. The substrate humidity is controlled at 50%~60%.

[0005] Preferably, the height of the Gastrodia elata planting layer is set to 50-70cm; the height of the Armillaria mellea culture layer is set to 15-30cm. A base plate is laid at the bottom of the Gastrodia elata planting layer on the planting rack, and several mesh holes are opened on the base plate to facilitate the Armillaria mellea mycelium to reach the bottom of the Gastrodia elata planting layer and then climb onto the base plate. The planting basket measures 60*40*25cm, with several mesh structures on the bottom and sides. The mesh structure provides good air permeability to the Gastrodia elata planting substrate. In addition, Armillaria mellea mycelium can pass through the mesh structure at the bottom to reach the Gastrodia elata seed tuber.

[0006] Preferably, each planting basket contains 2-3 sets of Armillaria mellea bags, with equidistant spacing between adjacent Armillaria mellea bags; the difference between the length of each Armillaria mellea bag and the width of the planting basket is no more than 1 cm. A vertical grid layer is placed inside the Armillaria mellea culture layer of the planting rack to guide the upward growth of Armillaria mellea mycelia and accelerate their growth to reach the bottom of the Gastrodia elata planting layer; the Armillaria mellea package is placed below the grid layer.

[0007] Preferably, black shading netting is laid around the Gastrodia elata planting layer and Armillaria mellea culture layer to prevent direct sunlight from forming, while allowing diffused light to pass through.

[0008] Preferably, the thickness of the sawdust mixture at the bottom of the planting basket is 5-10cm; two rows of Gastrodia elata seeds are placed in each planting basket, and the spacing between adjacent Gastrodia elata seeds in each row is set to 15-20cm. The thickness of the substrate covering the Gastrodia elata seed is 3-6 cm.

[0009] Preferably, 2 to 3 sets of drip irrigation heads are arranged in each planting basket corresponding to each layer of Gastrodia elata planting layer; the drip irrigation heads are connected to the drip irrigation system through pipelines; when the substrate moisture is lower than 50%, the drip irrigation heads are turned on to replenish the moisture content of the planting substrate and ensure that the substrate moisture is maintained in the range of 50% to 60%.

[0010] Preferably, the bottom plate of the Gastrodia elata planting layer is designed with a high center and low sides; the inclination angle from the center to the sides is 2~4°; the planting basket is placed on the inclination plate. Several guide channels are opened on the base plate, and the two ends of the guide channels converge into the collection channels on both sides of the Gastrodia elata planting layer; the bottom of the collection channel is connected to the water and fertilizer collection layer at the bottom of the planting frame through a drainage pipe.

[0011] Preferably, the water and fertilizer collection layer collects water and fertilizer from top to bottom, which then flows to the filter layer below to filter out solid particulate impurities in the collected water and fertilizer. The filtered water and fertilizer are then recycled back to the drip irrigation system for reuse.

[0012] Preferably, the spacing between two adjacent rows of planting racks is set to 80-100cm to allow for air circulation between the planting racks. Ventilation openings at the top of the greenhouse control exhaust air, while ventilation openings near the bottom of the greenhouse control air intake air, forming a vertical ventilation channel.

[0013] Preferably, a circulating fan is installed above each of the Gastrodia elata planting layers and Armillaria mellea culture layers, and a convection channel is formed between the circulating fans installed on two adjacent Gastrodia elata planting layers and Armillaria mellea culture layers; when the temperature difference between any two adjacent Gastrodia elata planting layers or Armillaria mellea culture layers exceeds 1.5℃, the circulating fan of the corresponding layer is activated until the temperature difference between the two layers is reduced to below 0.5℃.

[0014] The beneficial effects of this invention are: This invention provides an intensive cultivation method for Gastrodia elata in a factory setting. Following the concept of symbiosis between Armillaria mellea and Gastrodia elata, and utilizing Armillaria mellea mycelium to provide nutrients for Gastrodia elata growth, this method breaks away from the traditional cultivation method where Gastrodia elata must be cultivated in the same pond or frame as Armillaria mellea. The cultivation space for Armillaria mellea is separated from the growth space for Gastrodia elata, while ensuring that the Armillaria mellea mycelium can reach and integrate with the Gastrodia elata seed tuber. The two have independent cultivation spaces, eliminating the need for transplanting Armillaria mellea mycelium. As a core element for Gastrodia elata growth, the growth of Armillaria mellea mycelium can be monitored throughout the entire growth cycle, allowing for necessary interventions to ensure that the mycelium density and length remain at a high standard, thus ensuring sufficient nutrients are provided for Gastrodia elata growth. Given the unique spatial distribution of Gastrodia elata with mycelium at the bottom and Gastrodia elata seed tubers at the top, a layer of sawdust mixture is first laid at the bottom of the Gastrodia elata planting basket, and then the Gastrodia elata seed tubers are placed on top of the planting substrate. The bottom sawdust layer is loose and porous, which will not affect the mycelium from penetrating the sawdust layer and reaching the Gastrodia elata seed tubers. The rough, porous and loose structure of the sawdust can also provide a climbing structure for the mycelium to grow upward. In addition, the lignin and cellulose in the sawdust can be decomposed by Armillaria mellea mycelium and used as nutrients for its own growth. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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. Example

[0018] S1: Three-dimensional planting zoning. In this embodiment, the three-dimensional planting rack has 7 layers, with the bottom layer being the water and fertilizer collection layer 4. The remaining layers are designated as staggered areas for Gastrodia elata cultivation and Armillaria mellea cultivation, such as... Figure 2 As shown, from top to bottom, the planting layer 2 of Gastrodia elata and the culture layer 3 of Armillaria mellea are arranged in a cycle until the layer above the water and fertilizer collection layer 4 is reached; the height of the planting layer 2 of Gastrodia elata is set to 60cm, and the height of the culture layer 3 of Armillaria mellea is set to 20cm; a bottom plate is set at the bottom of the planting layer 2 of Gastrodia elata, and several mesh holes are opened on the bottom plate. S2: Set up planting baskets and Armillaria mellea culture bags, and arrange them in the following order from the top of the three-dimensional planting rack: upper layer of Gastrodia elata planting layer 2 and lower layer of Armillaria mellea culture layer 3; planting baskets 5 are set on the Gastrodia elata planting layer 2 and Armillaria mellea culture bags are set on the Armillaria mellea culture layer 3. Planting baskets 5 are laid on the base plate and used as the supporting carrier for planting Gastrodia elata. In this embodiment, the size of the planting basket 5 is set to 60*40*25cm. Mesh structures are opened on the bottom and sides of the planting basket 5. The mesh structure can give the planting basket 5 good water permeability and air permeability. Mesh structures are opened on the bottom plate and the bottom of the planting basket to improve air permeability and allow the mycelium of Armillaria mellea growing below to pass through the bottom plate and the bottom of the planting basket 5 to reach the planting basket 5. Armillaria mellea culture layer 3 is covered with Armillaria mellea bags 6. The Armillaria mellea bags 6 are commercially available Armillaria mellea culture bags that can be purchased directly. The Armillaria mellea culture bags are filled with a substrate suitable for the growth of Armillaria mellea and have been inoculated with Armillaria mellea spores. The pH of the substrate inside the bags is 4.5~5.5, which is slightly acidic. Three sets of Armillaria mellea bags 6 are set under each planting basket 5 to ensure that there is enough mycelium to grow and provide nutrients for the growth of Gastrodia elata above. The length of the Armillaria mellea bag 6 is equal to the width of the planting basket 5, or the difference between the length of the Armillaria mellea bag 6 and the width of the planting basket 5 is no more than 1 cm. A vertical grid layer 7 structure is set inside the Armillaria mellea culture layer 3. The grid layer 7 should be made of a material with a relatively rough surface so that the mycelium can stably attach to the surface of the grid layer 7. The purpose of setting the layer as a vertical grid structure is to guide the Armillaria mellea mycelium upward, correct the growth of the Armillaria mellea mycelium in other directions, so that it grows upward and promotes it to grow rapidly to reach the bottom of the Gastrodia elata planting layer. Since both Gastrodia elata and Armillaria mellea require a cool, dark environment to grow, they only need a small amount of diffused light. Therefore, black shading nets are laid around the Gastrodia elata planting layer 2 and the Armillaria mellea cultivation layer 3 to block direct sunlight, allowing only some diffused light to be provided for the growth of Gastrodia elata and Armillaria mellea. S3: Mycelium cultivation. Direct sunlight is blocked around the planting rack of Armillaria mellea cultivation layer 3, allowing only weak scattered light to pass through. Armillaria mellea mainly invades the seeds and tubers of Gastrodia elata through mycelium, so the cultivation mainly focuses on the mycelium of Armillaria mellea. The optimal temperature for mycelium growth is 22~25℃, and the humidity is controlled at 65%~70%. Under this temperature and humidity environment, the mycelium growth rate and quality are optimal. Humidity monitoring sensors are installed in the Armillaria mellea cultivation layer 3 and the substrate of the Armillaria mellea cultivation bag. At the same time, each layer of Armillaria mellea cultivation layer 3 is equipped with atomizing nozzles for humidification. By monitoring the humidity of the Armillaria mellea cultivation layer 3 and the substrate of the cultivation bag in real time, the PLC automatic control system controls the solenoid valves of the atomizing nozzles to automatically adjust the humidity environment for the growth of Armillaria mellea. S4: Planting of Gastrodia elata. White Gastrodia elata seeds should be selected and planted using asexual reproduction. The weight of the white Gastrodia elata seeds should be between 40 and 50g, with no mechanical damage, no disease spots, and no pests. A layer of sawdust mixture is laid at the bottom of planting basket 5. Shavings are preferred. The thickness of the sawdust mixture is 8cm. Then, the Gastrodia elata seeds are placed on the sawdust mixture. Two rows of Gastrodia elata seeds are placed in each planting basket 5. The spacing between adjacent seeds in each row is 15cm. 6-8 Gastrodia elata seeds are planted in the entire planting basket 5. After the seeds are placed, a substrate is laid to cover them. The thickness of the substrate is 5cm. The substrate consists of 70% humus soil + 25% bio-wood + 5% wheat bran. The sawdust and wood chip mixture at the bottom of the Gastrodia elata planting basket 5 has good air permeability and water retention, which helps maintain the humidity of the Gastrodia elata planting substrate above. Most importantly, the sawdust and wood chip mixture has a loose and porous structure. After the Armillaria mellea mycelium grows to the bottom of the Gastrodia elata planting layer, the sawdust and wood chip mixture will not prevent the Armillaria mellea mycelium from penetrating through the sawdust and wood chip mixture and continuing to grow upward until it invades the Gastrodia elata seed tuber, thus providing nutrients for the Gastrodia elata seed. The lignin, cellulose and other substances in the sawdust and wood chip mixture can be decomposed by the Armillaria mellea mycelium and used as nutrients for its own growth, which helps to increase the mycelial density and the thickness of the mycelial cords in the later stage. Good mycelial and mycelial cord growth can provide more sufficient nutrients for the growth of Gastrodia elata. Furthermore, the three-dimensional intensive planting model of this invention separates the planting space of Gastrodia elata and the growth space of Armillaria mellea, forming an independent upper and lower layer relationship. This not only satisfies the fundamental requirement that Gastrodia elata must rely on Armillaria mellea for nutrients to grow, but also breaks the planting idea that the two must be in the same spatial area for symbiosis. This is conducive to independent regulation according to the growth environment required by Armillaria mellea and Gastrodia elata, ensuring that each obtains the best growth conditions in the most suitable environment, without having to compromise between the two. In addition, Armillaria mellea is in an independent and monitorable growth space. Throughout the planting cycle, Armillaria mellea can be artificially monitored and intervened. Interference from miscellaneous bacteria or pathogens can be intervened in a timely manner to ensure the growth quality of Armillaria mellea, thereby ensuring that Armillaria mellea can provide sufficient nutrients for Gastrodia elata. Within the Gastrodia elata planting layer 2, the suitable temperature for Gastrodia elata growth is controlled at 20-25℃, the ambient air humidity at 70%-90%, and the humidity of the planting substrate at 50%-60%. Similarly, atomizing nozzles are used to regulate the ambient humidity, and drip irrigation is used to regulate the humidity of the planting substrate. Each planting basket 5 is equipped with two drip irrigation heads, which are connected to a water and fertilizer storage tank via pipelines. The flow of water and fertilizer is controlled by a pump. Electrically controlled valves are installed on the drip irrigation heads. Based on real-time monitoring of the planting substrate humidity, a PLC system controls the opening and closing of the pump and the electrical control valves on the drip irrigation heads. When the humidity of the Gastrodia elata planting substrate is below 50%, drip irrigation is activated to replenish the substrate moisture content, bringing it back to the suitable range for Gastrodia elata growth. Similarly, the air humidity within the Gastrodia elata planting layer is monitored by a humidity sensor, and the PLC controls whether to activate the atomizing nozzles. like Figure 2 The planting method provided in this embodiment sets the bottom plate of the Gastrodia elata planting layer to a structure that is high in the middle and low on both sides, forming a 3° tilt angle from the middle of the bottom plate to both sides; the planting baskets 5 are placed on the tilted bottom plate in sequence. In addition to several mesh openings, several horizontal guide channels are also opened on the bottom plate. The two ends of the bottom plate guide channels converge into the collection channels 8 on both sides of the Gastrodia elata planting layer 2. At the bottom of the collection channels 8, a drainage pipe connects to the water and fertilizer collection layer 4 at the bottom of the planting rack. Excess water and fertilizer in the planting basket 5 leaks from the bottom of the planting basket 5 to the bottom plate, and is guided to both sides by the guide channels of the bottom plate to the collection channels 8 on both sides of the Gastrodia elata planting layer 2. The water and fertilizer collected in each collection channel 8 from top to bottom are collected layer by layer, and finally reach the water and fertilizer collection layer 4. Collecting water and fertilizer can not only prevent excessive water and fertilizer from flowing directly onto the Armillaria mellea culture layer 3 below, but also allow the collected water and fertilizer to be recycled. The water and fertilizer collected into the water and fertilizer collection layer 4 first pass through the filtration layer 9 to remove particles and other impurities. The filtered water and fertilizer are then collected in the water and fertilizer storage tank for recycling. Ventilation and exhaust systems for the overall planting environment are set up with ventilation openings at the top of the greenhouse, equipped with exhaust fans to control exhaust airflow. Ventilation openings are also located on the sides near the bottom of the greenhouse, equipped with intake fans to control airflow. The spacing between adjacent rows of planting racks is set at 100cm to allow for air circulation between the racks. Natural ventilation is the primary method, with fans assisting in accelerating vertical airflow exchange to prevent hot air from accumulating in the upper layers. Shading nets are also installed at the top of the greenhouse to prevent direct sunlight from causing excessively high temperatures inside the greenhouse, especially at the top, which would damage the shade-loving growth environment of Gastrodia elata and Armillaria mellea. In a vertical space, hot air naturally rises while cold air sinks, easily resulting in higher temperatures in the upper layers and lower temperatures in the lower layers. Since the optimal growth temperatures for Armillaria mellea and Gastrodia elata differ, separate independent temperature control systems are used for each. Each layer of Gastrodia elata cultivation is equipped with a circulating fan. The circulating fans between adjacent layers form a convection channel through pipes or flexible passages. One end of the convection channel connects to the upper layer of Gastrodia elata cultivation, and the other end connects to the lower layer. When the temperature difference between two adjacent layers exceeds 1.5℃, the circulating fans in both layers are activated, allowing the hot and cold air from both layers to convect and merge within the convection channel, thus regulating the temperature difference until it is reduced to 0.5℃. Similarly, a circulating fan is installed above each layer of Armillaria mellea culture layer, and a convection channel is also set up between the circulating fans of two adjacent layers of Armillaria mellea culture layer. The circulating fans on the two adjacent layers form a hot and cold gas exchange in the convection channel, so as to regulate the temperature difference between the two layers until the temperature difference is reduced to 0.5℃.

[0019] Independent temperature regulation is applied to each layer of Gastrodia elata planting and Armillaria mellea culture layer, which helps to unify and coordinate the temperature between the same layers and avoid differences in planting quality caused by excessive temperature differences. In addition, temperature control is applied to Gastrodia elata and Armillaria mellea to keep them in their respective adaptive temperature environments and obtain the most suitable growth conditions.
