How to Grow Huagu Mushrooms for High Yield? Latest Cultivation Technique Tutorial
Huagu mushrooms are produced when shiitake mushrooms are stimulated by certain specific environmental conditions, with a natural occurrence rate of 4-5%. No pesticides, fertilizers or any hormones are used during production, and they are free from any contamination, reaching organic food standards. With rich nutrition and effects such as disease prevention, health promotion and delaying aging, they are deeply welcomed by people at home and abroad. Now let us take a look at the high-yield cultivation technique for Huagu mushrooms!
Mushroom Shed Construction
Choose a sunny, well-ventilated, flat area with dry soil and convenient access for materials to build an east-west oriented mushroom shed. The shed is 6 m long, 2.6 m wide and 2.4 m high. Build 3 brick walls at both ends and in the middle of the shed, with the upper ends of the walls curved. Leave a door 2 m high and 0.6 m wide in the middle, and leave a square vent 12 cm on each side above the doors at both ends. Use bamboo poles as shelves, 8 poles per layer, with a layer spacing of 33 cm, for a total of 6 layers, which can hold 500 fungus bags. Cover the shelves with wide film.
Planting Time
Huagu mushrooms are divided into three types: spring planting, autumn planting and winter planting. Generally, they are planted in autumn, when most of the shiitake mushrooms produced are Huagu mushrooms, with relatively good economic value. When the daily average temperature is 26-28°C, it can meet the temperature requirements of shiitake mushroom mycelium. After 60-70 days of growth, the mycelium can fill the bag, and after another 10-15 days, color conversion is completed. Generally, fruiting begins in November. Before the Spring Festival, 2 flushes of Huagu mushrooms can be produced; after the Spring Festival, 1 flush of Huagu mushrooms, 1 flush of thick mushrooms and 1 flush of thin mushrooms are produced.
Nutrient Preparation
Use oak and fruit tree sawdust as the main ingredients, and crop straw (soybean stalks, cotton stalk wood), wheat bran and quicklime as auxiliary ingredients, of which sawdust is no less than 70% and fresh wheat bran no less than 20%. When mixing the ingredients, first pour the sawdust and other main ingredients into the mixing yard and pile them into a cone shape, then sprinkle the fresh wheat bran and gypsum from the top of the pile to the surroundings, dry-mix 2-3 times to mix them evenly, then mix soluble additives such as sugar and monopotassium phosphate into water, and sprinkle the mixture into the dry ingredients in several batches while stirring. The mixing should achieve “two evennesses and one sufficiency”, namely various dry ingredients are mixed evenly, the moisture of the ingredients is even, and the raw materials absorb water sufficiently.
Bagging and Sterilization
Adopt large-bag cultivation. Cut low-pressure polyethylene plastic tube film 25 cm wide into 55 cm long sections, then tie one end tightly with cotton thread, and burn it with candle flame until it melts into a small ball shape. Put the culture material into the bag. The material should be packed appropriately tight but not too tight. After filling, tie the opening with cotton thread and place it on the ground covered with gunny sacks. The prepared culture material should be bagged within 6-8 hours. Put the filled material bags into a normal-pressure sterilization stove, and at the same time put the outer sleeve bags with one end sealed (bag length 58 cm, width 26 cm) and absorbent cotton into the steamer for sterilization. Leave a gap 20-30 cm high in the pot, burn with high heat so that the temperature in the pot reaches 100°C within 4-6 hours, then maintain the temperature for 36 hours. After stopping the fire, open the pot, and when the material temperature drops to 70°C, take it out of the pot and transport it to the inoculation room.
