Description

Technical Field

[0001] This invention belongs to the field of Gastrodia elata cultivation technology, and specifically relates to a method for large-scale cultivation of Gastrodia elata. Background Technology

[0002] Gastrodia elata is a plant used for both medicinal and culinary purposes, and its potential for consumption is immeasurable. First, it has a similar morphology and texture to tuberous plants like potatoes, but is even more nutritious. It has been reported that approximately 90 species of the genus Gastrodia elata have been discovered worldwide. This vast diversity and abundant germplasm resources provide a wide range of breeding materials for artificial breeding, allowing for hybridization and targeted breeding to meet the diverse needs of different populations and satisfy both culinary and health requirements. Second, Gastrodia elata possesses remarkable biotransformation efficiency; industrialized production can achieve a production rate of [missing information - likely a unit of measurement] per cubic meter. 3 With a yield of over 30kg, it can be produced twice a year and is not restricted by geographical or climatic conditions. Third, industrialized production of Gastrodia elata can completely eliminate the pollution from chemical fertilizers, pesticides, and heavy metals, using pollution-free materials to produce natural food.

[0003] The industrialized production of Gastrodia elata using substrate-substitute cultivation technology is based on this technology. It utilizes modern equipment and intelligent management to cultivate Gastrodia elata year-round in greenhouses using a three-dimensional, multi-layered cultivation system. This technology involves using mechanized production lines to artificially produce Armillaria mellea (mushroom sticks) instead of logs for cultivating Gastrodia elata. Gastrodia elata's growth characteristics differ from both common plants and edible fungi such as black fungus and shiitake mushrooms. It can grow without light or soil and can be planted in multiple layers, making it easier to integrate into industrialized production systems.

[0004] Patent application number CN201410587936.9 discloses a soilless three-dimensional cultivation method for Gastrodia elata, the specific steps of which are as follows: (1) Material preparation: Broadleaf tree leaves or crushed crop waste are used as materials for cultivating Armillaria mellea; prepare broadleaf tree segments, gravel, plastic baskets, and plastic film. The length of the broadleaf tree segments is determined according to the size of the plastic baskets, and the gravel is 10-20 mesh.

[0005] (2) Quantities per plastic basket: 27-29 kg of gravel, 5-6 kg of broadleaf tree segments, 1.5-2 kg of broadleaf tree leaves or crushed crop waste, 1-1.2 kg of Armillaria mellea, 0.5-0.7 kg of germination fungus, and 0.2-0.3 kg of Gastrodia elata seeds.

[0006] (3) Planting: (3.1) Before planting, mix the seeds of Gastrodia elata, gravel, broad-leaved tree leaves or crushed agricultural waste with 10-50 times diluted New High-Lipid Film to prevent disease invasion.

[0007] (3.2) Line a plastic basket with a layer of plastic film, then a layer of gravel, and then a layer of broadleaf tree leaves or crushed crop scraps. Place the prepared broadleaf tree segments evenly on top, with a spacing of 1-3 cm between the segments, and 3-4 segments per layer. Place the Armillaria mellea close to both sides of the broadleaf tree segments, and then place the Gastrodia elata seeds between the segments to quickly establish a symbiotic relationship. After that, sprinkle a layer of germination fungus, then a layer of broadleaf tree leaves or crushed crop scraps. Then, add another layer of gravel, and repeat this process. One plastic basket can be planted with 2-3 layers. The plastic film inside the basket should be folded up on all four sides and wrapped around the top of the basket, leaving only a few gaps for ventilation.

[0008] (3.3) Three-dimensional placement: Stack the planted plastic baskets in multiple layers; they can be placed both outdoors and indoors.

[0009] (4) Post-planting management: Keep the water content in the plastic basket at 40-50% and the temperature at 15-28℃; in the hot summer season, use shade nets or tree branches to shade and cool down or place it indoors.

[0010] (5) Pest control: The plastic film inside the plastic basket is turned up on all four sides and wrapped around the top of the basket, with only a few gaps exposed. There is no need to drain water or spray pesticides to control pests.

[0011] For example, patent application number CN 202411289352.3 discloses an intensive, industrialized, and modernized method for cultivating Gastrodia elata, using factory-style cultivation plastic turnover baskets. The specifications of the turnover baskets are (inner diameter) 635cm*440cm*400cm. The difference between the special turnover baskets and ordinary plastic baskets is that the four sides of the basket are board-like without holes, while the bottom has holes; the upper side has four additional holes, which can allow two water pipes to pass through. The specific steps are as follows: Step 1: Grind the wood and pine / fir wood chips into wood chips using a wood chipper. One basket of material (wet) requires approximately 15 kg.

[0012] Step 2: 10kg of Gastrodia elata nutrient pack (or substitute substrate fungus pack, i.e., Armillaria mellea pack).

[0013] Step 3: 10 kg of tender wood branches.

[0014] Step 4: 0.2 kg of 0th generation Gastrodia elata seedlings (or Gastrodia elata seeds).

[0015] Sowing method: Lay a 2cm thick layer of pine and fir sawdust at the bottom of the basket. Cut 10kg of branches into 15cm long pieces and plant them upright in the basket, filling the gaps with sawdust. Cut 10kg of Armillaria mellea bags (about 8 bags) into two sections, about 10cm long, making 16 bags, and plant them upright on top of the mushroom branches. Fill the gaps with sawdust. Then, plant the Gastrodia elata seedlings head-up and tail-down on the side of the mushroom bag, with two seedlings per bag, for a total of about 32 seeds. Alternatively, the seeds can be laid flat on the surface of the mushroom bag and covered with a 5cm thick layer of sawdust. The sawdust used should have a low moisture content. Over 70%; cover the surface with a black film to retain moisture and block light, leaving a 65cm aisle between the two rows; Step 5: adjust the temperature of the cultivation room to 18-20℃, with natural humidity; after about 10 days, the mycelium of Armillaria mellea grows on the surface of the basket, and the Gastrodia elata seeds are inoculated with the mycelium; adjust the room temperature to 22-23℃; ventilate twice a day for 10 minutes each time; after 20 days, check the moisture in the basket. If the moisture content of the sawdust is below 60%, add water. After watering thoroughly, turn off the valve and cover with a film; water once every 25 days or so; after about 20 days, the mycelium of Armillaria mellea will have basically covered the surface of the basket.

[0016] Artificial watering: Reach in through the hand hole at the top of the basket to remove the plastic film on the basket surface, and spray water directly onto the surface with the movable water hose until it is saturated; then cover it with the plastic film.

[0017] Automatic water replenishment: A micro-spray water pipe runs parallel to the hand hole on the basket, with both ends connected to the main pipe and equipped with switches. When watering, remove the film and turn on the water pipe switches in layers or simultaneously. Water 4-5 times throughout the entire production period. During the sowing period, the moisture content of the sawdust substrate should be 75%-80%, the wetter the better, and the film should be tightly covered. Check the substrate moisture 20 days after sowing and replenish water to above 75% if necessary. Sufficient moisture not only promotes rapid mycelial growth of Armillaria mellea but also inhibits the reproduction of other microorganisms. Generation 0 Gastrodia elata seeds are not afraid of high humidity. Maintain high humidity for 45-50 days, after which Armillaria mellea will have thoroughly consumed the bottom substrate and branches, and the overall habitat will enter a safe period. After 50 days, reduce the substrate moisture to 60% and maintain this level for 90 days. After 90 days, reduce the substrate moisture to 50%, and on days 110-120, the substrate moisture should be approximately 40%-45%. Temperature management: Start with a room temperature of 18-20℃, adjust to 22-23℃ after 10 days, and maintain this temperature for 30 days. At this point, the temperature inside the basket will rise, exceeding the room temperature by 3-5℃. Adjust the temperature to 20℃ and maintain it for 100 days of growth, at which point the gastrodia elata is basically mature. Then begin to lower the temperature; reduce the temperature by 1-2℃ each day, and after 5 days, lower it to 15℃. Maintain this temperature for 15 days to end the growth period and harvest the gastrodia elata. Ventilation management: Do not ventilate for the first 10 days; ventilate twice a day for 10 minutes each time for the next 10 days; ventilate three times a day for 10 minutes each time after 20 days; ventilate four times a day for 10 minutes each time after 40 days; ventilate five times a day for 10 minutes each time after 50 days; ventilate six times a day for 10 minutes each time after 60 days; ventilate three times a day for 10 minutes each time after 100 days; ventilate twice a day for 10 minutes each time after 110 days. The entire production period is 120 days.

[0018] As can be seen from the above patents, the existing planting process is complex and requires strict control, particularly regarding temperature and ventilation. Furthermore, the culture medium is complex, requiring the addition of other nutrients besides sawdust. This results in high planting costs. Summary of the Invention

[0019] To address the aforementioned problems, this invention provides a method for large-scale cultivation of Gastrodia elata, which features a simple culture medium, a straightforward cultivation process, and low cost. The technical solution is as follows: This invention provides a method for large-scale cultivation of Gastrodia elata, the method comprising: S1 culture medium pretreatment: Chestnut wood is crushed to a size of 4-7mm to obtain chestnut wood chips, which are first piled up and fermented for 3-6 months, and then soaked in water in a sealed container for 30-60 days. The process of pile fermentation and soaking achieves material transformation and sterilization.

[0020] S2 Inoculation: A plastic bag is placed inside the culture basket (closely against the inner wall of the basket, forming a culture space (specifically a rectangular trough)). Soaked chestnut sawdust is used as the culture medium. The culture medium, Armillaria mellea, and Gastrodia elata seeds are inoculated and planted within the space of the plastic bag. The inoculation rate of Armillaria mellea is 32-45 kg / m². 3 The volume of the cultivation basket should be such that the inoculation rate of Gastrodia elata seeds is 160-240 seeds / m². 3 The volume of the cultivation basket should be such that the top of the chestnut sawdust protrudes beyond the basket (after a period of planting, the volume of the culture medium will change, from a bulging state to a partially filled state, to ensure sufficient medium volume). After inoculation, seal the plastic bag (specifically, it can be folded and sealed). The bottom of the plastic bag has multiple drainage holes for drainage; the size and density of the holes should ensure natural water seepage and prolonged moisture retention. At the same time, the size of the drainage holes should be such that chestnut sawdust cannot pass through.

[0021] S3 cultivation: The culture medium should be replenished with water every 20-50 days to ensure that the moisture content of the culture medium is 82-88% for the first 1-3 months (the period of Armillaria mellea growth), and 58-62% thereafter; Gastrodia elata is harvested after 6-8 months.

[0022] In step S1, the water is tap water or well water, which is required to be relatively clean and free of obvious sediment and algae.

[0023] In step S1, fresh or dried chestnut wood is crushed. Fermentation is carried out at room temperature, with the surface covered and turned over every 25-35 days. No other substances (such as microorganisms, inorganic matter, carbon sources, nitrogen sources, etc.) need to be added. The fermentation process is similar to that of conventional organic fertilizer. For fresh chestnut wood, fermentation should be carried out as soon as possible (e.g., within 10 days), without adding water. For dried chestnut wood, water is added during fermentation (the humidity is similar to that of conventional organic fertilizer fermentation). Preferably, fresh chestnut wood is crushed and fermented immediately after crushing. In summer, chestnut wood chips are soaked for 30-40 days; in winter, they are soaked for 45-60 days.

[0024] In step S1, the moisture content of the soaked chestnut wood chips is greater than or equal to 90%. During the inoculation process, the moisture content will be slightly reduced to meet the requirements.

[0025] Specifically, in step S2, the inoculation time is from October to March of the following year, and the temperature is 5-26℃; in step S3, the planting temperature is 18-26℃, and the harvest time is from August to November. During the planting process, only watering and observation of growth are required, and no other operations are needed.

[0026] The dimensions of the cultivation basket are 55-65cm (length) * 35-45cm (width) * 45-55cm (height), but this is not a limitation of this patent. Other sizes of cultivation baskets may be used depending on individual conditions or planting specifications. *Armillaria mellea* is inoculated using *Armillaria mellea* bags (consistent with existing technology), with an inoculation quantity of 3-4 bags, each bag weighing 1kg. The inoculation quantity of *Gastrodia elata* seeds is 15-20 seeds, with a seed weight of 8-14g (preferably around 10g).

[0027] Preferably, the Gastrodia elata seeds are inoculated in two layers, including the following steps: S201: After filling the bottom of the culture basket with culture medium to a height of 8-12cm.

[0028] S202: Place 1-2 Armillaria mellea bags flat on the surface of the culture medium, then fill the bags with culture medium to 1 / 3-2 / 3 of their height, and then inoculate 7-12 Gastrodia elata seeds, placing them around and close to the Armillaria mellea bags.

[0029] S203: Fill the culture medium to a height of 20-30cm (from the bottom of the culture basket).

[0030] S204: Then inoculate the second layer in the same manner as step S202.

[0031] S205: Then fill the culture medium into the protruding culture basket.

[0032] Specifically, the Gastrodia elata seeds are inoculated in two layers, including the following steps: S201: After filling the bottom of the culture basket with culture medium to a height of 10cm.

[0033] S202: Place two Armillaria mellea bags flat on the surface of the culture medium, then fill the bags with culture medium to half their height, and inoculate 8-10 Gastrodia elata seeds around and close to the Armillaria mellea bags; place 4-8 Gastrodia elata seeds around each Armillaria mellea bag.

[0034] S203: Fill the culture medium to 1 / 2 height of the culture basket.

[0035] S204: Then inoculate the second layer in the same manner as step S202.

[0036] S205: Then fill the culture medium into the protruding culture basket.

[0037] In step S3, planting is carried out indoors or in a shady outdoor environment, with the cultivation baskets stacked up to 6 layers high. The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: The embodiments of the present invention provide a method for large-scale cultivation of Gastrodia elata, which has a simple culture medium, a simple cultivation process, low cost, and is suitable for large-scale production. At the same time, the cultivation baskets can be stacked, saving space, and only the culture medium needs to be disinfected and replaced annually for replanting, eliminating the problem of non-continuous cropping in the field. The yield of a single cultivation basket is typically greater than or equal to 12 kg, and the yield per unit area is greater than or equal to 200 kg / m². 3 The produced Gastrodia elata are uniform in size, white, and regularly shaped.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1 Example 1 provides a method for large-scale cultivation of Gastrodia elata, characterized in that the method includes: S1 culture medium pretreatment: In winter, chestnut wood is crushed to a size of 5mm to obtain chestnut wood chips, which are first piled up for fermentation for 4 months, and then soaked in well water in a sealed container for 50 days. Planting location: Xiabaoping Village, Xiabaoping Township, Yiling District, Yichang City.

[0041] S2 Inoculation: The culture basket dimensions are 60cm*40cm*50cm. Plastic bags are placed inside the culture basket, and soaked chestnut sawdust is used as the culture medium. Inoculation is carried out in January, using *Armillaria mellea* and *Gastrodia elata* seeds. The inoculation quantity for *Armillaria mellea* is 4 bags, each bag weighing 1kg. The inoculation quantity for *Gastrodia elata* seeds is 18 seeds, each weighing approximately 10g. The specific process is as follows: S201: After filling the bottom of the culture basket with culture medium to a height of 10cm.

[0042] S202: Place two Armillaria mellea bags flat on the surface of the culture medium, then fill the bags with culture medium to half their height, and then inoculate nine Gastrodia elata seeds, placing them around and close to the Armillaria mellea bags.

[0043] S203: Fill the culture medium to 1 / 2 height of the culture basket.

[0044] S204: Then inoculate the second layer in the same manner as step S202.

[0045] S205: Then fill the culture medium into the protruding culture basket.

[0046] S3 cultivation: Cultivation is carried out indoors, and the culture medium is replenished with water every 40 days or so. Gastrodia elata is harvested in August.

[0047] The harvested Gastrodia elata are white, clean, and regularly shaped. The yield per cultivation basket is 10-15 kg (fresh weight, the same below), with an average of 12.2 kg (based on 84 cultivation baskets); the weight of a single Gastrodia elata is 300-350 g (excluding obviously underdeveloped ones, the same below), with an average weight of 317 g. With cultivation baskets stacked in 4 layers, the yield per unit area is 203 kg / m². 3 This is 10-12 times that of existing technologies (soil cultivation).

[0048] Example 2 Example 2 provides a method for large-scale cultivation of Gastrodia elata, characterized in that the method includes: S1 culture medium pretreatment: In summer, chestnut wood is crushed to a size of 5mm to obtain chestnut wood chips, which are first piled up for fermentation for 5 months, and then soaked in well water in a sealed container for 30 days. Planting location: Xiabaoping Village, Xiabaoping Township, Yiling District, Yichang City.

[0049] S2 Inoculation: The culture basket dimensions are 60cm*40cm*50cm. Plastic bags are placed inside the culture basket, and soaked chestnut sawdust is used as the culture medium. Inoculation is carried out in November, inoculating with Armillaria mellea and Gastrodia elata seeds. The inoculation quantity of Armillaria mellea is 3 bags, with each bag weighing 1kg. The inoculation quantity of Gastrodia elata seeds is 16, with each seed weighing approximately 10g. The specific process is as follows: S201: After filling the bottom of the culture basket with culture medium to a height of 10cm.

[0050] S202: Place two Armillaria mellea bags flat on the surface of the culture medium, then fill the bags with culture medium to half their height, and then inoculate 10 Gastrodia elata seeds, placing them around and close to the Armillaria mellea bags.

[0051] S203: Fill the culture medium to 1 / 2 height of the culture basket.

[0052] S204: Inoculate the second layer in the same way as in step S202. In this step, place one Armillaria mellea bag flat and inoculate 6 Gastrodia elata seeds.

[0053] S205: Then fill the culture medium into the protruding culture basket.

[0054] S3 cultivation: Cultivation is carried out indoors, and the culture medium is replenished with water every 30 days or so. Gastrodia elata is harvested in July.

[0055] The harvested Gastrodia elata are white, clean, and regularly shaped. The yield per cultivation basket is 10-15 kg, with an average of 12.3 kg (based on 116 cultivation baskets); the weight of a single Gastrodia elata is 300-350 g, with an average weight of 311 g. With cultivation baskets stacked in four layers, the yield per unit area is 205 kg / m². 3 This is 10-12 times that of existing technologies (soil cultivation).

[0056] Comparative Example 1 The process is the same as in Example 1, except that cherry wood is used instead of chestnut wood. The yield per cultivation basket is 7-12 kg, with an average of 8.7 kg (based on 42 cultivation baskets); the weight of a single Gastrodia elata is 150-280 g, with an average weight of 225 g.

[0057] Comparative Example 2 The process is the same as in Example 1, except that poplar wood is used instead of chestnut wood. The yield per cultivation basket is 7-12 kg, with an average of 8.5 kg (based on 36 cultivation baskets); the weight of a single Gastrodia elata is 120-280 g, with an average weight of 203 g.

[0058] Comparing documents 1 and 2, it can be seen that the effect of ordinary wood is average, while the effect of using chestnut wood is better.

[0059] Comparative Example 3 The process is the same as in Example 1, except that: after fermentation, the chestnut sawdust is not soaked; during inoculation, the chestnut sawdust is soaked until the moisture content is 85%. The yield per culture basket is 5-10 kg, with an average of 6.9 kg (based on 36 culture baskets); the weight of a single Gastrodia elata is 80-250 g, with an average weight of 174 g.

[0060] Comparative Example 4 The process is the same as in Example 1, except that the chestnut wood chips are not fermented but soaked directly. The yield per cultivation basket is 2-6 kg, with an average of 4.5 kg (based on 40 cultivation baskets); the weight of a single Gastrodia elata is 50-233 g, with an average weight of 131 g.

[0061] As can be seen from the comparison documents 3 and 4, in this patent, the fermentation and soaking processes are indispensable. Without either process, the yield and the size of individual Gastrodia elata are far from ideal.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
