Detailed Explanation of the Key Points of Rapid Bud-induction Technology for 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 best season for cultivating flower shiitake mushrooms is missed, both yield and quality will be affected. Below, the editor has summarized the bud-induction technology for shiitake mushrooms. Let's take a look.

1. Directional puncturing

Four iron nails 8-10 cm long can be nailed onto a wooden board 45 cm long and of suitable width, forming a row of nails. Prick each side of the mushroom log once with them, creating eight puncture holes, which can make the mushrooms emerge quickly.

2. Timed soaking of the bags

Place the punctured mushroom logs into a wooden barrel, preventing them from floating up, 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 mushrooms twice need to be soaked for 2-3 hours each time. For soaking, it is appropriate that the water content near the puncture holes be 65%-75% and the water content of other parts be 45%-60%. A weighing method is generally used to determine the amount of soaking water. After the first soaking, the weight of the mushroom log should be 100% of the cultivation weight, while for spring-planted bags the weight should 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 need 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 carefully. During the day, sunlight exposure raises the temperature inside the film to between 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. Fruiting 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 the early morning of the third day, place the logs with more buds on the lower layer of the mushroom shed. After that, every half a day to a day, move them into the mushroom shed from bottom to top, completing all of them within 3 days.
