How to Plant King Oyster Mushrooms
King oyster mushrooms, being a highly nutritious edible mushroom, can be grown at home to ensure the freshness of ingredients and to experience the joy of cultivation. This article will detail the hydroponic planting techniques through four core steps, helping beginners easily master the entire process from mycelium treatment to harvest.
Core Techniques of Hydroponic Cultivation of King Oyster Mushrooms
Accurate Treatment of Mycelium Roots
Select king oyster mushrooms with soil-covered stems, and use disinfected knives to cut off 2-3 cm of the mycelium roots along the boundary line. Retaining the active layer of the mycelium is the key to success; the incision should be kept flat to avoid fiber tearing, and the treated mycelium roots should be immediately transferred to the cultivation environment.
Building an Intelligent Hydroponic System
Use wide-mouth shallow containers to ensure oxygen exchange, and prepare a 0.5% baking soda solution to adjust the pH to the range of 6.5-7.0. Place sterile cotton filter paper on the water surface to form a layer for the mycelium to attach to, and wrap the outer wall of the container with aluminum foil for light-free cultivation.
Accurate Control of Environmental Parameters
Maintain a constant temperature environment of 8-15°C, and keep the humidity within the range of 85%-95%. Ventilate twice a day, each for 15 minutes, and use a spray device to supplement water without directly impacting the mycelium.
Management of King Oyster Mushroom Growth Cycle
How to Plant King Oyster Mushrooms
Mycelium Activation Stage (1-5 Days)
Keep a completely dark environment, change the solution weekly and supplement with 0.1g/L glucose. During this stage, the mycelium expands in a white fluffy form, and the container must not be moved.
Formation Stage of Fruiting Body (6-12 Days)
After the appearance of rice-like primordia, increase scattered light exposure by 1 hour/day. Keep temperature fluctuations within ±2°C range, and at this point, the stem starts to differentiate.
Maturity Harvesting Stage (13-15 Days)
Harvest immediately when the diameter of the mushroom cap reaches 1 cm, using a rotational picking method to retain the basal mycelium. After harvesting, change the culture solution for a second flush of mushrooms.
Advanced Techniques for Planting King Oyster Mushrooms
Opt for cultivation from late autumn to early spring, and using magnetized water can increase yield by 15%. Regularly adding VB2 solution can promote stem elongation, and when yellowing occurs, supplement with a 0.05% magnesium sulfate solution.
Through scientific hydroponic management, the biological conversion rate of home-grown king oyster mushrooms can reach over 80%. Mastering the two core elements of temperature and humidity control and nutritional ratio can achieve annual production, with each harvest interval controlled at around 20 days.
