The Latest Technical Method Tutorial for Rapidly Inducing Bud Formation in Shiitake Mushrooms

During the cultivation of shiitake mushrooms, bud induction is carried out to improve yield and quality. However, if mushrooms fail to emerge for a long time after bud induction and the optimal season for cultivating flower shiitake mushrooms is missed, it will affect yield and quality. Below, the editor has summarized the bud induction techniques for shiitake mushrooms. Let's take a look.

1. Directional puncturing

You can use four iron nails 8-10 cm long and nail them onto a wooden board 45 cm long and of suitable width, forming a row of nails. Puncture the mushroom logs once on each side with them, creating eight puncture holes, which can promote rapid mushroom emergence.

2. Timed bag soaking

Place the punctured mushroom logs into a wooden barrel, prevent them from floating up, and then soak them in a low-concentration urea solution. Logs that have already produced their first flush of mushrooms generally need to be soaked for 1.5-2 hours, while those that have produced two flushes need to be soaked for 2-3 hours each time. For soaking, it is appropriate for the water content near the puncture holes to be 65%-75% and the water content in other parts to be 45%-60%. Generally, the weighing method is used to determine the amount of soaking water. After the first soaking, the weight of the mushroom log should mainly be 100% of the cultivation weight, while for spring-planted bags the weight should mainly be 90%. Each subsequent soaking should reduce the amount of soaking water by about 15%.

3. Bud induction by temperature difference

Choose a sunny day with a day-night temperature difference of 8-20 degrees to begin bud induction. The nighttime temperature must be below 12 degrees, and medium-temperature strains also require low-temperature stimulation of 14-16 degrees. Puncture holes in one end of the soaked mushroom logs, place the holes facing downward, and arrange them on ground that is sheltered from the wind, faces the sun, and does not accumulate water. Then cover them with plastic film, place a thermometer, and monitor the temperature well. During the day, sunlight exposure causes the temperature inside the film to reach as high as 28-32 degrees. After maintaining this for 1-4 hours, uncover the film and stimulate with the low nighttime temperature for 4-6 hours.

4. Mushroom emergence management

After puncturing, soaking, and temperature-difference stimulation, the mushroom logs can be placed directly in the same spot and tightly covered with plastic film. In an environment of 18-24 degrees, a large number of mushroom buds will grow in about 2-3 days. From the evening of the second day or early morning of the third day, place the mushroom logs with more buds onto the lower layer of the mushroom shed. After that, every half day to one day, move them from bottom to top into the mushroom shed, completing all of them within 3 days.
