In order to obtain high output and do well the stage management of hericium Erinaceus

In order to obtain high yield and high yield of hericium Erinaceus, the following management must be strengthened in the stage of growing mushroom:

Hericium Erinaceus

1. Adjust the temperature: after the bag is put into the field, the temperature should be reduced from the original stage to the optimum temperature of 16 ℃ ~ 20 ℃ in the mushroom stage. In a suitable temperature environment, it usually takes about 10 to 12 days from small bud to mature mushroom. When the temperature exceeded 23 ℃, the fruiting body of hericium Erinaceus developed slowly, the stalk proliferated continuously, and the mushroom body was distributed into cauliflower-like deformed mushrooms, or no spiny Pleurotus ostreatus. More than 25 ℃, the mushroom body will shrink. Therefore, in the stage of mushroom emergence, special attention should be paid to controlling the temperature. If the temperature exceeds the prescribed temperature, measures can be taken: spray atomized water in ① space. ② furrow irrigation humidification. The shade cover of ③ was thickened. ④ staggered the ventilation time and carried out the film opening ventilation in the morning and evening. Open both ends of the cover at noon to make the air flow smoothly. Create a suitable temperature to promote the smooth growth of young buds.

2. Strengthen ventilation: hericium Erinaceus is good for air, such as poor ventilation, excessive carbon dioxide deposition, stimulate continuous branching of stalks, inhibit the development of the central part, and coral-shaped abnormal mushrooms will appear. In this kind of saturated humidity and still air, it is easy to become deformed mushroom, or miscellaneous bacteria breeding pollution. For this reason, the film should be ventilated for half an hour at 8 o'clock every morning. When the fruiting body grows up, it should be ventilated in the morning and evening every day, and the ventilation time should be extended appropriately. But avoid the wind blowing directly on the mushroom body, so as not to shrink.

3. Humidity control: water must be managed scientifically during the growth and development of hericium Erinaceus fruiting body, and different amounts of water should be sprayed according to the size, surface color and climate of the mushroom. Mushroom small do not spray, especially the ground bag or hole down bag, the use of wet on the line, generally do not spray water. If the climate is dry, you can store water in the ditch and let the water evaporate on the mushroom body. Whether the humidity is appropriate can be observed from the bristles, if the bristles are fresh white and elastic, indicating that the humidity is suitable; if the mushroom body is yellow, the bristles are not obvious, and the growth speed is slow, then the humidity is insufficient, and it is necessary to spray water to humidify. Water spraying must be combined with ventilation to make the air fresh and the fruiting body thrive. However, it is necessary to strictly prevent excessive spraying of water blindly, resulting in mildew of the fruiting body. The cultivation site must create 85% to 90% air relative humidity. Young mushrooms are sensitive to space humidity, and if less than 70%, the differentiated fruiting bodies stop growing. Even if the growth resumes after humidification, permanent marks remain on the surface of the mushroom body. If it is higher than 95%, coupled with poor ventilation, it is easy to cause miscellaneous bacteria pollution. Can be taken: ① furrow irrigation to increase ground moisture. ② spray head upside down, space spray. ③ covers the bed tightly and moisturizes with plastic film. ④ young bud stage shelf layer cultivation, can be covered with wet gauze or newspaper to increase humidity.

4. Moderate illumination: there should be scattered light during the growing period, usually 300 to 600 lux illumination. The field shed mastered "one-third of yang and seven points of yin, flowers and sunlight" to meet the growth needs of fruiting bodies.

5. Harvest at the right time and skillfully manage regenerated mushrooms:

Hericium Erinaceus usually lasts 10-12 days from the emergence of the buds to the maturity of the fruit body. Some can mature 8 or 10 days ahead of time. Signs of maturity: the mushroom body is white, the spines are rough, and the spores begin to eject, accumulating a thin layer of white powder on the surface of the bag. According to the requirements of hericium Erinaceus market, the maturity of harvest is slightly different. Hericium Erinaceus, which is used as a dish fresh-keeping or salinized processing, is best harvested when the spines have not yet extended, or have been formed but not more than 0.5 cm in length, and have not yet released a large number of spores. At this time, the color is white, the flavor is delicious and pure, and there is no bitterness or slight bitterness. If hericium Erinaceus is used as a medicinal hericium Erinaceus, with dehydration and drying as a commodity, the maturity of the seed can be prolonged, and it is better to harvest about 1 cm of spines.

Hericium Erinaceus can generally be harvested in 3 batches and some in 4 batches, but the first 1-2 batches have high yield and high grade, accounting for 80% of the total output. The cultivation of regenerated mushrooms is to stop spraying water for 3 days after the first batch of mushrooms are harvested, remove the film and ventilate for 12 hours, let the surface of the mushroom roots shrink after harvest to prevent mildew, and then adjust the temperature to 23 ℃ ~ 25 ℃ to make the mycelium volume accumulate nutrients. The primordium appeared in about 5 days, and the young buds formed in about 10 days. At this time, the temperature was reduced to 16 ℃ ~ 20 ℃, the air humidity was increased to about 90%, and the fruiting body grew healthily. The whole production cycle ends in 60-70 days under normal temperature conditions, and the bioconversion rate is generally 90%-100%.
