Description

Technical Field

[0001] This invention relates to the field of fungal cultivation, specifically to an indoor cultivation and fruiting device for shiitake mushrooms. Background Technology

[0002] As a nutritious edible fungus with high market demand, the artificial cultivation technology of chicken leg mushrooms, especially the intensive indoor cultivation model, has become the mainstream direction of industry development. Although indoor cultivation can effectively control environmental conditions such as temperature, humidity, and light, and avoid the impact of outdoor natural environmental fluctuations on growth, there are still many problems with existing fruiting devices and cultivation methods that need to be solved, which restrict the yield, quality, and cultivation efficiency of chicken leg mushrooms.

[0003] Current indoor cultivation of chicken leg mushrooms mostly employs single-layer flat laying or simple multi-layer rack structures. The fruiting containers are haphazardly arranged with inconsistent spacing, resulting in poor ventilation, uneven temperature and humidity, and susceptibility to contamination by other microorganisms. Furthermore, space utilization is not fully optimized, leading to low yields per unit area. Regarding nutrient supply, traditional cultivation often uses a single substrate or loose nutrient material, which suffers from easy nutrient loss and uneven supply. It is also difficult to precisely control the contact between the substrate and the nutrient source, resulting in inconsistent mycelial germination and growth rates, and poor fruiting uniformity.

[0004] Furthermore, the drainage and aeration design of existing mushroom cultivation containers is flawed. Either excessive drainage leads to substrate dryness, or insufficient aeration causes waterlogging and rotting, affecting root respiration and mycelial vitality, thus increasing the risk of mushroom rot. Simultaneously, the substrate bags have poor stability, easily shifting during fruiting, and lack targeted fruiting guidance structures, resulting in disordered and irregular fruiting body growth and reduced commercial value. In addition, traditional cultivation methods are cumbersome, lacking standardized procedures for nutrient preparation and substrate bag placement, hindering large-scale and standardized cultivation and further limiting the improvement of quality and efficiency in the indoor cultivation of *Coprinus comatus*.

[0005] Based on the shortcomings of the existing technologies, there is an urgent need for an indoor cultivation and fruiting device for Coprinus comatus that has a reasonable structure, precise nutrient supply, excellent ventilation and drainage performance, good fruiting guidance, and is easy to standardize operation, so as to solve the problems of low yield, poor quality, and low cultivation efficiency in the existing technologies. Summary of the Invention

[0006] Therefore, to address the aforementioned shortcomings, this invention provides an indoor cultivation and fruiting device for *Coprinus comatus*. This device features a rational structure, precise nutrient supply, excellent ventilation and drainage, good fruiting guidance, and ease of standardized operation.

[0007] The present invention is implemented as follows: an indoor cultivation and fruiting device for chicken leg mushrooms is constructed, characterized in that: a fruiting rack (2) is set in a cultivation shed (1), the fruiting rack (2) is longitudinally divided into multiple layers, and multiple sets of fruiting frames (3) are evenly arranged in each layer. The mushroom growing frame (3) is a rectangular structure with closed sides. Multiple drainage and ventilation holes (3-1) are opened at the bottom of the mushroom growing frame (3). The bottom of the inner cavity of the mushroom growing frame (3) is filled with thick nutrient mud (3-2).

[0008] According to the present invention, an indoor cultivation and fruiting device for Coprinus comatus is characterized in that: the nutrient mud (3-2) is prepared by mixing granular clay or sand with nutrient water in a weight ratio of 1:1, the nutrient water being prepared by mixing water, potassium dihydrogen phosphate, glucose, and water-soluble fertilizer of medium elements; round mushroom bags (3-3) containing Coprinus comatus spawn are filled into the thick nutrient mud (3-2), and a layer of granular clay (3-4) is placed on top of the round mushroom bags; the area 1 cm below the horizontal diameter line of the round mushroom bags is immersed in the mud; the clay layer (3-4) is buried 3 cm above the round mushroom bags, and the clay layer is a mixture of Φ1-2 cm clay particles and nutrient water.

[0009] According to the present invention, an indoor cultivation device for shiitake mushrooms is characterized in that: the weight ratio of nutrient water, clean water, potassium dihydrogen phosphate, glucose, and water-soluble fertilizer of medium elements is 100:1:3:0.5; the clay layer is a mixture of Φ1-2cm clay particles and nutrient water at a weight ratio of 10:6; the granular clay particles have certain gaps, which can be used for air permeability and facilitate the fruiting and growth of shiitake mushrooms.

[0010] According to the present invention, a mushroom cultivation device for indoor cultivation of chicken leg mushrooms is characterized in that: the bottom of the mushroom frame (3) has 4, 6 or 9 Φ1cm drainage and ventilation holes.

[0011] According to the present invention, a mushroom cultivation device for indoor cultivation of chicken leg mushrooms is characterized in that: mushroom growing frames (3) are arranged on mushroom growing racks (2), and the mushroom growing racks (2) are arranged at intervals of 1m within the cultivation shed (1).

[0012] According to the present invention, an indoor cultivation and fruiting device for Coprinus comatus is characterized in that the gap size of the granular clay layer is adapted to the needs of Coprinus comatus mycelial penetration and fruiting body growth, and has both air permeability and fruiting guidance functions.

[0013] The indoor cultivation and fruiting device for shiitake mushrooms according to the present invention is characterized in that the implementation method includes the following steps: Step 1: Build a planting shed (1) and set up mushroom racks (2) inside the shed. Divide the mushroom racks (2) into multiple layers along the longitudinal direction. Arrange multiple sets of mushroom frames (3) evenly on each layer. Control the installation spacing of adjacent mushroom racks in the planting shed (1) to be 1m. Step 2: Prepare nutrient mud (3-2). Mix granular clay or sand with nutrient water in a weight ratio of 1:1 according to the formula. The nutrient water is made by mixing water, potassium dihydrogen phosphate, glucose, and water-soluble fertilizer of medium elements. Mix and stir until thick. Then fill the bottom of the inner cavity of the mushroom box (3) with the thick nutrient mud (3-2). Step 3: Embed circular mushroom bags (3-3) into the filled thick nutrient mud (3-2). The circular mushroom bags (3-3) are made of Coprinus comatus. The circular mushroom bags (3-3) are immersed in the nutrient mud (3-2) at a position 1 cm below the horizontal diameter line. Step 4: Cover the surface of the circular mushroom bag (3-3) with a granular clay layer (3-4). The granular clay layer (3-4) has a certain gap, which allows for air permeability and provides a channel for the growth of the chicken leg mushroom. This completes the setup of the device and the preparation for planting.

[0014] According to the present invention, the indoor cultivation and fruiting device for Coprinus comatus is characterized in that: in step 4, the size of the gaps reserved in the granular clay layer (3-4) is adapted to the needs of Coprinus comatus mycelium penetration and fruiting body growth, and has both air permeability and fruiting guidance functions.

[0015] According to the present invention, a mushroom cultivation shed for chicken leg mushrooms is characterized in that: the distance between the round mushroom bags (3-3) is 2cm; and the diameter of the round mushroom bags (3-3) is 10cm.

[0016] This invention has the following advantages: The indoor cultivation device and method for growing shiitake mushrooms address the shortcomings of existing technologies and have the following beneficial effects: (1) Improve space utilization and greenhouse environment stability: Through the design of multi-layer mushroom racks and the standardized arrangement of mushroom frames with a spacing of 1m, the vertical space inside the greenhouse can be maximized, the planting density per unit area can be increased, and the air circulation inside the greenhouse can be ensured to be smooth, so that the temperature, humidity and permeability of each layer and area are uniform and consistent, effectively reducing the probability of contamination by miscellaneous bacteria and creating a stable environment for the growth of chicken leg mushrooms.

[0017] (2) Precise nutrient supply to promote mycelial and fruiting body growth: The special nutrient mud formula (granular soil, water, glucose, potassium dihydrogen phosphate and medium element water-soluble fertilizer) can provide balanced and long-lasting nutrients for chicken leg mushrooms. The thick texture can reduce nutrient loss. At the same time, the circular mushroom bag is immersed in the mud 1cm below the horizontal diameter line to achieve precise contact between the mushroom bag and the nutrient source. This not only meets the nutrient and water requirements for mycelial germination, but also avoids the mushroom bag from being over-soaked and rotting, which significantly improves the mycelial germination rate and growth uniformity.

[0018] (3) Optimize drainage and ventilation performance to avoid the risk of mushroom rot: 4, 6 or 9 Φ1cm drainage and ventilation holes are opened at the bottom of the mushroom box according to the specifications. Excess water can be discharged quickly, while ensuring air circulation and maintaining the appropriate humidity and ventilation of the substrate. Combined with the gap structure of the granular clay layer, a dual ventilation system of "bottom channel + surface gap" is formed, which effectively solves the problems of substrate water accumulation and lack of oxygen, and reduces the occurrence of mushroom rot from the root.

[0019] (4) It has both fruiting guidance and protection functions, and improves product quality: The size of the gaps in the granular clay layer is suitable for the penetration of mycelium and the growth of fruiting bodies of Coprinus comatus. It can provide a breathable channel for mycelium growth and guide the fruiting bodies of Coprinus comatus, promoting the regular growth of fruiting bodies and avoiding messy shapes. At the same time, the clay layer can protect the mushroom bag and mycelium, reduce the impact of external environmental fluctuations on growth, and improve the appearance and overall quality of Coprinus comatus products.

[0020] (5) High degree of standardization, which facilitates large-scale promotion: The structure of the device and the steps of planting are clear. The specifications of the mushroom box, the formula of the nutrient mud, the depth of the mushroom bag, and the requirements for the clay layer coverage are all standardized. The operation is simple and easy to learn. No complicated technical experience is required. Large-scale planting can be achieved quickly, significantly improving planting efficiency and reducing labor management costs, providing strong support for the indoor intensive planting industry of chicken leg mushroom.

[0022] The following will be combined with the appendix Figures 1-4 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] Example: An indoor cultivation and fruiting device for shiitake mushrooms, such as... Figures 1-4 As shown, it can be implemented in the following manner; including a mushroom growing rack (2) set in the planting shed (1), the mushroom growing rack (2) is divided into multiple layers in the longitudinal direction, and multiple sets of mushroom growing frames (3) are evenly arranged in each layer; the mushroom growing frame (3) is a cuboid structure with closed sides, and multiple drainage and ventilation holes (3-1) are opened at the bottom of the mushroom growing frame (3), and the bottom of the inner cavity of the mushroom growing frame (3) is filled with thick nutrient mud (3-2).

[0024] When implementing the indoor cultivation and fruiting device for chicken leg mushrooms described in this invention, the nutrient mud formula is prepared by mixing granular clay or sand with nutrient water at a weight ratio of 1:1. The nutrient water is composed of water, potassium dihydrogen phosphate, glucose, and water-soluble fertilizer of medium elements. The weight ratio of water, potassium dihydrogen phosphate, glucose, and water-soluble fertilizer of medium elements can be 100:1:3:0.5.

[0025] Fill the thick nutrient slurry (3-2) with round mushroom bags (3-3), which contain spores of *Coprinus comatus*. Cover the round mushroom bags with a layer of granular clay (3-4). Immerse the round mushroom bags in the slurry up to 1 cm below their horizontal diameter. The clay layer (3-4) should be 3 cm above the round mushroom bags. The clay layer consists of 1-2 cm Φ clay particles mixed with the nutrient water at a weight ratio of 10:6.

[0026] Mushroom-growing frames (3) are arranged on mushroom-growing racks (2), and the mushroom-growing racks (2) are arranged at intervals of 1m within the planting shed (1).

[0027] In the implementation of this invention, the mushroom-growing frames (3) are installed in the planting shed (1) with a spacing of 1m. The size of the gaps in the granular clay layer (3-4) is adapted to the needs of the mycelium penetration and fruiting body growth of the chicken leg mushroom, and has both air permeability and fruiting guidance functions.

[0028] The spacing between the mushroom bags is 2cm, and the diameter of the mushroom bags is 10cm.

[0029] The indoor cultivation and fruiting device for chicken leg mushrooms described in this invention includes the following steps: Step 1: Build a planting shed 1 and set up mushroom growing racks 2 inside the shed. Divide the mushroom growing racks 2 into multiple layers along the longitudinal direction. Arrange multiple sets of mushroom growing frames 3 evenly on each layer. Control the installation spacing of adjacent mushroom growing racks 2 in the planting shed 1 to be 1m. Step 2: Prepare nutrient mud 3-2. According to the formula, add granular clay or sand to nutrient water and mix until it becomes thick. Then fill the bottom of the inner cavity of the mushroom box 3 with the thick nutrient mud 3-2. Step 3: Embed circular mushroom bags 3-3 into the filled thick nutrient mud 3-2. The circular mushroom bags 3-3 are of the Coprinus comatus strain. The circular mushroom bags 3-3 are immersed in the nutrient mud 3-2 at a position 1 cm below the horizontal diameter line. Step 4: Cover the surface of the circular mushroom bag 3-3 with a granular clay layer 3-4. The granular clay layer 3-4 has a certain gap, which allows for air permeability and provides a channel for the growth of the chicken leg mushroom. This completes the device setup and planting preparation.

[0030] In step 4, the gaps reserved in the granular clay layer 3-4 are adapted to the needs of the mycelium penetration and fruiting body growth of the chicken leg mushroom, and have both air permeability and fruiting guidance functions.

[0031] The implementation process of the indoor cultivation and fruiting device for shiitake mushrooms of this invention strictly follows a standardized procedure, and is carried out in stages and in an orderly manner, taking into account the structural characteristics of the device and the cultivation technical requirements. The specific steps are as follows: (I) Preliminary Preparation Stage 1. Construction of the cultivation shed: Select a site with good ventilation and flat terrain to construct cultivation shed 1. The shed body is made of steel or bamboo and wood structure. The size is adjusted according to the planting scale. The area of ​​a single shed is usually controlled at 50-100㎡ (or other specifications). The roof is covered with heat-insulating and light-transmitting film. Adjustable ventilation openings are set on the sides of the shed. Temperature and humidity monitoring instruments and control equipment (such as humidifiers, ventilation fans, and heating pipes) are installed inside to ensure that the temperature inside the shed can be maintained at 15-25℃ and the humidity at 60-85%, which meets the growth requirements of chicken leg mushrooms.

[0032] 2. Preparation of mushroom growing racks and frames: Mushroom growing rack 2 is made of anti-corrosion wood or galvanized steel, with an overall height of 2.0-2.5m. It is divided into 3-5 layers longitudinally, with a spacing of 40-50cm between each layer. The layers have a perforated structure to enhance air permeability, and the width of the layers is adapted to the size of mushroom growing frame 3. Mushroom growing frame 3 is made into a rectangular structure with closed sides, with specifications of 60cm long × 40cm wide × 15cm high. The bottom has 4, 6, or 9 Φ1cm drainage and ventilation holes 3-1, which are evenly distributed at the four corners and the center of the bottom to ensure uniform drainage and ventilation. The inner wall of the mushroom growing frame is polished smooth to avoid scratching the mycelium.

[0033] 3. Raw material preparation: Prepare granular soil (0.5-1cm in diameter, selected from fertile garden soil that has been sun-dried and sterilized before being crushed and screened), potassium dihydrogen phosphate (food grade), clean water, round mushroom bags (e.g., 8-10cm in diameter, cultivated from robust chicken leg mushroom spawn, with the mycelium age controlled at 25-30 days), and granular clay (0.3-0.8cm in diameter, sterilized at high temperature before use to ensure no residual bacteria).

[0034] (II) Equipment Layout Stage 1. Installation of mushroom growing racks and frames: The prepared mushroom growing racks 2 are evenly distributed in the growing shed 1 to facilitate manual operation and ventilation. Then, mushroom growing frames 3 are evenly arranged on each layer of the mushroom growing racks, and the installation distance between adjacent mushroom growing racks 2 in the shed is controlled to be 1m to ensure smooth air circulation around each mushroom growing frame and avoid shading between layers and frames that may affect growth.

[0035] 2. Nutrient slurry preparation and filling: Prepare the nutrient slurry according to the formula ratio. Take 100kg of granular soil, add 100kg of water (100% of the soil weight), 1kg of potassium dihydrogen phosphate (1% of the soil and water weight), 3kg of glucose, and 0.5kg of water-soluble fertilizer containing medium-quantity elements. Put the mixture into a mixing device and stir for 10 minutes until the mixture becomes thick (insert a 1cm diameter, 30cm long wooden stick 20cm into the slurry without tipping over). After stirring, slowly fill the nutrient slurry to the bottom of the inner cavity of mushroom frame 3, controlling the filling thickness to 5-6cm. During the filling process, gently vibrate the mushroom frame to remove air bubbles inside the slurry, ensuring that the slurry is laid flat and compacted.

[0036] 3. Insertion of Mushroom Bags and Covering with Clay: After the nutrient slurry is laid flat, insert circular mushroom bags into the slurry surface at a spacing of 2cm x 2cm. When inserting, gently press the bags to ensure that 1cm below the horizontal diameter line of the bag is immersed in the slurry. This ensures sufficient contact between the bag and the nutrient slurry while preventing over-soaking and rotting. After insertion, evenly cover the surface of the circular bags with a granular clay layer, 2-3cm thick. Leave gaps naturally during covering, with the gap size controlled at 0.2-0.5cm, to accommodate the mycelial penetration and fruiting body growth requirements of *Coprinus comatus*. After covering, gently pat the surface clay to smooth it out, ensuring a tight fit between the clay and the bag surface while maintaining ventilation gaps.

[0037] (III) Post-harvest management and fruiting stage 1. Environmental Control: After the equipment is installed, close 80% of the ventilation openings in the cultivation shed, maintain an internal temperature of 20-22℃ and humidity of 75-80%, ensure sufficient oxygen, and cultivate in the dark for 7-10 days to promote mycelial germination until the mycelium penetrates the clay layer. Once the mushrooms have grown into young mushrooms, adjust the humidity to 80-85%, maintain an internal temperature of 18-20℃, completely close the ventilation openings in the cultivation shed, prohibit air circulation, and maintain darkness until all mushrooms are harvested.

[0038] 2. Routine maintenance: Regularly check for contamination by miscellaneous bacteria. If local miscellaneous bacteria are found, promptly remove the contaminated mushroom bags and surrounding clay and mud to prevent their spread.

[0039] 3. Harvesting and Recycling: Harvest the chicken leg mushrooms when the cap diameter reaches 3-5cm and the stem height reaches 8-10cm. When harvesting, gently hold the base of the stem and rotate it to pull it out, avoiding damage to the surrounding mycelium. After harvesting, clean the remaining stems and debris from the fruiting frame, add a small amount of nutrient mud and clay, and let it stand for 3-5 days before starting the next fruiting cycle. A single fruiting frame can be harvested 3-4 times.

[0040] The social benefits of this invention will be described below; The widespread application of this device and cultivation method can generate significant social benefits and contribute to the high-quality development of the edible fungi industry, specifically in the following aspects: 1. Promote the standardized and intensive development of the chicken leg mushroom cultivation industry: Currently, indoor cultivation of chicken leg mushrooms is mostly carried out by small-scale individual farmers with varying levels of technical expertise. This device, through standardized structural design and standardized cultivation process, unifies key aspects such as nutrient supply, environmental control, and mushroom management, changing the traditional cultivation model of "relying on experience and intuition," guiding the industry towards standardization and intensification, and improving the overall cultivation level and product quality stability of the industry.

[0041] 2. Boosting Employment and Income: The equipment is simple to operate and has low barriers to entry, requiring no complex technical experience, making it suitable for large-scale planting by farmers and cooperatives. Its promotion can create employment opportunities for surplus rural labor, including in planting management, harvesting and processing, and raw material preparation, increasing farmers' operating and wage income. Simultaneously, it forms a "planting-harvesting-sales" industrial chain, promoting the development of rural specialty industries and broadening rural economic income channels.

[0042] 3. Improve resource utilization and realize the concept of green agriculture: The nutrient mud formula uses common granular soil and a small amount of potassium dihydrogen phosphate. The raw materials are readily available, low in cost, and recyclable. After harvesting, the raw materials can be replenished for repeated planting, reducing resource waste. Indoor intensive planting mode can avoid the occupation of arable land by outdoor planting, make full use of idle factory buildings, sheds and other spaces, and avoid excessive use of pesticides and fertilizers, reducing pollution to the ecological environment, which is in line with the needs of green agricultural development.

[0043] 4. Ensuring food safety and meeting market demand: The controlled indoor environment and standardized planting process effectively reduce the probability of contamination by miscellaneous bacteria and pests, reduce pesticide use, and improve the safety of chicken leg mushroom products. At the same time, the equipment increases the yield and quality of chicken leg mushrooms, ensuring a stable supply to the market, meeting consumers' demand for high-quality and safe edible fungi, enriching residents' dining options, and enhancing food safety assurance.

[0044] The economic value of this invention will be explained below; This device and planting method have significant advantages in terms of input-output ratio, which can create considerable economic benefits for growers and cooperatives, while also driving the added value of related industries, as detailed below: 1. Increased yield per unit area and higher planting profits: By utilizing the vertical space of multi-layer mushroom racks and adopting a standardized layout, the planting density per unit area is increased by 2-3 times compared to the traditional single-layer flat-laying method. Simultaneously, precise nutrient supply, optimized drainage and aeration design, and a mushroom-guiding structure improve the uniformity of chicken leg mushroom growth by over 40% and reduce the rate of rotten mushrooms by over 30%. A single crop yield can reach 800-1000 kg per mu (approximately 0.16 acres), an increase of about 50% compared to traditional planting methods. Based on a market average price of 10-12 yuan / kg, the annual net profit per unit area can increase by 20,000-30,000 yuan.

[0045] 2. Reduce planting costs and increase profit margins: On the one hand, the equipment has a simple structure and readily available raw materials. The mushroom growing racks and frames are reusable (with a service life of 3-5 years), and the cost of the nutrient mud formula is only 1 / 3 of that of traditional loose nutrient materials. On the other hand, the standardized planting process reduces labor management costs, with each person able to manage 500-800 sets of mushroom growing frames, increasing labor efficiency by more than 2 times compared to traditional planting. Overall, calculations show that the planting cost per acre can be reduced by 20-30%, significantly increasing the profit margins for growers.

[0046] 3. Enhance product value and expand sales channels: The fruiting guidance function of the granular clay layer makes the chicken leg mushrooms more uniform in shape and size, improving the product grade by 1-2 levels, with a premium product rate of over 90%. Premium products command a 20-30% premium over ordinary products. Simultaneously, stable quality and yield can attract supermarkets, catering companies, and deep-processing manufacturers to establish long-term partnerships, expanding sales channels, avoiding the risk of unsold inventory, and ensuring stable income for growers.

[0047] 4. Drive the extension of the industrial chain and create added value: Large-scale promotion of this equipment can drive the development of upstream and downstream industries. Upstream, it promotes the prosperity of raw material supply industries such as soil, potassium dihydrogen phosphate, and mushroom bag cultivation. Downstream, it promotes the development of industries such as deep processing of chicken leg mushrooms (such as pickling, drying, and processing of mushroom products), packaging, and logistics, thereby extending the industrial chain, creating more added value, and promoting regional economic development.
