AI Technical Summary
In the traditional cultivation method of large ball caisson mushrooms, the long cycle of mycelium bacteria, the dispersed mushroom production time, and extensive environmental parameter control lead to poor synchrony of bud appearance, making it difficult to achieve centralized management and efficient production.
Factory-based cultivation methods are adopted for vertical segmentation of bacteria rods, layered soil cladding and precise environmental regulation, including vertical segmentation of bacteria rods, layered soil cladding structure, CO₂ concentration monitoring and programmatic ventilation management, and are combined with humidity and light control during the bacterial and budding periods.
The bacterial cycle has been shortened to 25-30 days, the mushroom production concentration has reached 85%, the bioconversion rate has been increased by 20-30%, the operation is standardized, and the resource utilization rate is high, which is suitable for cultivation in early spring facilities in the north.
Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a factory-based efficient cultivation method of Stropharia rugosa based on vertical sowing of mushroom sticks and layered soil covering, which is particularly suitable for large-scale production in early spring in northern regions. Background Art
[0002] Stropharia rugosoannulata has attracted much attention due to its rich nutrition and wide range of cultivation materials. However, traditional cultivation methods have the following drawbacks: 1. The mycelium spawning cycle is as long as 45-50 days, and the fruiting time is scattered (the harvest period lasts 2-3 months), making centralized management difficult; 2. Conventional cultivation methods in facilities require pre-preparation of fermentation substrates, which is time-consuming and labor-intensive, and carries the risk of bacterial contamination. 3. The environmental parameters are controlled in a rough manner, the budding synchronization is poor, the harvesting period is relatively scattered, the mushroom batches are large, and the harvesting efficiency is low.
[0003] Therefore, there is an urgent need to develop a new cultivation method that can achieve rapid fungus growth, concentrated mushroom production, and high bioconversion rate. Summary of the Invention
[0004] A high-efficiency cultivation method for Stropharia rugosa is implemented according to the following steps: (1) Preparation of bacterial strains Select polyethylene bags with a ring size of 17 cm or above, and culture them in a dark environment at 22-25℃ and 65% humidity for 35-40 days until the mycelium fills the bag; after removing the bag, split the cylindrical mushroom stick in half along the axial direction into two semi-cylinders.
[0005] (2) Construction of cultivation beds Cultivation pits with a depth of 20-30cm and a width of 1-1.5m are dug in the greenhouse, with a distance of 30-40cm between adjacent pits; a breathable net with a pore size of 5mm can be laid at the bottom of the pit, and an atomizing spray pipe can be arranged above it.
[0006] (3) Vertical sowing When the ground temperature is ≥15℃ and the temperature in the greenhouse is ≥25℃ (preferably February-March in northern regions), place the semi-cylindrical mushroom sticks vertically at the bottom of the pit with the cut surface facing upwards, with a spacing of 5-10cm, to form a "mushroom wall" structure.
[0007] (4) Layered soil covering Bottom soil cover: backfill with original soil that has been exposed to sunlight and disinfected, completely covering the mushroom sticks and gaps, with a soil moisture content of 30-35%; Moisturizing layer: Lay a 3-5cm thick layer of straw or rice husk mixture and spray 0.1% lime water for disinfection.
[0008] (5) Environmental control Spawning period (from sowing to budding): Keep in a dark environment, with air humidity of 60-70% and temperature of 20-25℃; The CO2 concentration is tested every 3 days and controlled at ≤2000ppm.
[0009] Bud stage: Adjust to diffuse light (light intensity 500-800 lux) and humidity 50-60%; Ventilate twice a day, each time for 0.5-1 hour, and maintain a day-night temperature difference of 8-10℃.
[0010] Example (in a planting base in Xiqing District, Tianjin in 2025) Culture: Culture at 25°C for 38 days. When the mycelium fills a 17 cm bag, divide it into semi-cylinders. Constructing the cultivation bed: dig a 25cm deep and 1.2m wide cultivation pit and lay the misting pipe on the top; Vertical sowing: On March 30 (temperature in the greenhouse 26°C), place mushroom sticks vertically at intervals of 8 cm. Soil covering treatment: First cover with sterilized original soil (water content 32%), then lay a 3cm thick rice husk mixture layer; Environmental control: During the spawning period, the CO2 concentration should be controlled below 1800ppm. After the buds appear, ventilation should be carried out for 1 hour at 9:00 and 15:00 every day. Harvesting management: Buds appear 25 days after sowing, and the peak harvest period is 40 days.
