After the beginning of spring, the temperature gradually rises. If we can manage the mushroom beds that have been continuously mushroomed in the autumn of last year, we can easily give birth to a season of spring mushrooms. The specific method is as follows: 1, loose material fill soil. When the temperature rises to 10°C, loosen and fill the soil in time. This is not only conducive to the exclusion of the exhaust gas in culture materials, but also more conducive to the rupture of old mycelium, promote the growth of new hyphae, the formation of strong mycelium, lay the foundation for the increase in the yield of spring mushroom. Loose material points Dasong, Zhongsong and Komatsu should be determined according to the actual conditions of culture materials in the bed. For the growth of the mycelium in the material, and the bacterial bed of the soil mycelium knot, Dasong should be used. Fine soil can be scraped to one side, and bamboo sticks can be used to incline into the bottom of the soil to shake the coarse soil. The dried old hyphae can be removed and 0.2 kg of lime powder can be scattered per square meter. The fine soil can then be re-paved. For the bacterial bed where the hyphae of the soil are not prosperous, Zhongsong or Komatsu should be used. When the material is loosened, it is not necessary to scrape the fine soil, and even the coarse and fine soils are smashed together, and then the new soil is used to fill the depressions of the material surface. 2, top dressing replenishment. After continuous cultivation of the mushroom in the autumn of last year, the nutrient loss was severe and the pH value was reduced a lot. After spring, it is necessary to top-dress fertilizer and replenish water in time. All localities can adjust their measures to local conditions and draw materials locally. From one of the following methods, the effect of top-dressing and replenishing water is very satisfactory. (1) Fermented material dipping sauce. The dried fermented material was chopped, and 10 times the dry weight of boiling water was added. After immersing for one night, the filtered juice was taken, and 1 time of fresh water was further added to the bed surface. (2) Mushroom soup. The mushrooms will be cut down with the roots of the mushrooms, add water and boil for 15 minutes, and take the soup with 10 times more water as the bed topdressing, which will enable early mushrooming and prolong the peak period of mushrooming. (3) urea water. Taking 50 grams of urea, 10 grams of glucose plus 0.1% to 0.2% of urea water as topdressing, can significantly increase the yield in the middle and late period, and the mushroom quality is more white and tender. (4) Mushrooms. No. 1 Jianjinsu can play a role in rejuvenating mycelium and accelerating the growth of mycelia. No. 2 Jianjinsu can play a role in promoting the formation of fruit bodies and accelerating hypertrophy. When used, add 40-50 kilograms of fresh water per 100 grams, spray 0.3-0.4 kilograms per square meter. (5) Human and urine dilutions. Take fresh urine and boil until the foam disappears, add 10 times more water, spray 3 to 4 times before the mushrooming, spray 0.5 to 1 kg per square meter on the mushroom surface, and then spray with clean water after spraying. In addition, when topdressing before fruiting, it should also spray 1 to 2 times 2% lime water, adjusting the soil PH value between 7.8 to 8.5. 3, insulation and ventilation. Mushrooms should be protected against hypothermia in the early stages, and the water supply to the bacteria bed should not be premature, and the bed surface should not be too wet. Mushroom ventilation and water transfer should be carried out at noon, and heat preservation should be strengthened sooner or later. In the middle and late period of spring mushroom, it is necessary to focus on preventing high temperatures. During the day, doors and windows should be closed. Ventilation and ventilation should be carried out at night or in the early morning to avoid rising mushroom house temperature or causing mushrooms or mushrooms.
