Want high yields from edible mushrooms? These cultivation key points you need to master

1. Temperature difference stimulation method: Cover the mushroom bed with film during the day to raise the temperature, and uncover the film in the evening or morning to cool it down. During the early stage of mycelial growth, keep the relative humidity below 70%, and in the later stage keep it at 85%-90%, which can favor the formation of fruiting bodies.

2. Drug stimulation method: When preparing the substrate, appropriately add phosphates (monopotassium phosphate, superphosphate), sulfates (magnesium sulfate, calcium sulfate), vitamin B, etc., which have an obvious yield-increasing effect. In the later stage of mycelial growth, spray triacontanol onto the surface of the substrate to promote mycelial growth. Generally, it can increase yield by 0%-5%.

3. Scratching method: When the mycelium grows all over the surface of the substrate, use a clean bamboo broom to gently sweep back and forth over the surface of the substrate to remove or damage the spindly and old mycelium on the surface layer, exposing new mycelium, then spray water and cover with film to preserve moisture and warmth. Buds will appear and mushrooms will emerge 7 days after sweeping. Generally, it can increase yield by about 0%.

4. Startling method: After the surface of the substrate is fully covered with mycelium, use elastic wooden slats to press and pat the surface of the substrate. When operating, apply force evenly, do not leave deep marks, and do not damage the surface of the substrate. This can promote mycelial growth and rapid differentiation of fruiting bodies. This method is suitable for shiitake mushrooms, oyster mushrooms, Phoenix-tail mushrooms, and wood ear mushrooms, etc., and generally can increase growth efficiency by about 5%.

5. Contact method: Cover the surface of the substrate with old newspapers, gunny sacks, fine soil, etc. Pressure stimulation can promote rapid mycelial growth. You can also use sterilized small wooden sticks (diameter cm, length 3 cm) inserted about 2 cm deep into the substrate, with a stick spacing of 5 cm x 5 cm, so that when the mycelium spreads it touches the small wooden sticks and wraps around them, forming a uniform and dense mycelial mass. Generally, it can increase yield by about 20%.

6. Hole-punching and sand-filling method: Punching holes in the surface of the substrate and filling them with sand can improve the air permeability of the mushroom bed, enhance the water retention performance of the substrate surface, and make mushroom emergence uniform with large caps and thick flesh.

Method: When sowing, use a conical wooden stick with a diameter of .5 cm and a length of 30 cm, and according to the specification of 30 cm between plants and rows, punch holes in a plum-blossom pattern, with the holes reaching the bottom of the substrate. After two days, fill the holes with yellow sand (soaked and disinfected with % potassium permanganate solution), filling until it is cm above the substrate surface; at the same time, pour 0.3%-0.5% lime water into the holes. Using this method can advance mushroom emergence by 3-4 days, and the mushrooms emerge uniformly and the fruiting bodies are plump.
