The management measures of bagged shiitake mushrooms after mushroom production play an important role in ensuring the yield and quality of shiitake edodes. The following are the detailed management measures:
Shiitake mushrooms belong to the variable temperature and fruiting fungi, and a certain temperature difference, scattered light and fresh air are conducive to the differentiation of fruiting body primordium. In the budding stage, the cover film should be removed, so that the temperature of the mushroom greenhouse is controlled at 10 22, and there can be a temperature difference of 5 10 between day and night. If the natural temperature difference is small, it can be artificially widened by ventilation during the day and at night.
The relative humidity of the air should be maintained at about 90%. When the conditions are right, white cracks will appear on the surface of the column in 3 to 4 days, and mushroom buds will grow soon.
Avoid low space humidity or lack of water in the bacterial column, so as not to affect the formation of fruiting body primordium. If this happens, increase the spray of water, spray the water and dry until the surface of the fungus column is not sticky and slippery, but only damp, and then cover with plastic film to moisturize.
At the same time, it is necessary to prevent high temperature and high humidity to prevent miscellaneous bacteria pollution and rotten bacteria columns. Once high temperature and high humidity occur, ventilation should be strengthened, cooling and humidity should be reduced.
After the mushroom buds are differentiated, they enter the growth and development period. The temperature of fruiting body growth and development of different temperature types of Lentinus edodes was different, and the suitable temperature for medium-temperature strains was 15-25, and the suitable temperature for low-temperature strains was 10-20. The relative humidity of the environment should be kept at 80-90%.
Pay attention to ventilation to avoid the accumulation of carbon dioxide and affect the growth of shiitake mushrooms.
For varieties that are not easy to change color, the scattered light should be increased in the color turning area, and the number of bag turning should be increased to promote color change. Special attention should be paid to weather changes and before and after hitting the front and back to avoid causing deformed mushrooms or long fleshy tumors to appear in the mushroom bag in advance.
In order to improve the quality of mushrooms in the later stage, the soaking time should be shortened, so that the water content of the mushroom blocks is about 70% (lower than that of conventional management).
The method of reducing the water content and environmental humidity of the mushroom block was adopted to make the fruiting body grow and mature in a relatively unfavorable environment, so as to improve the quality of lentinan edo.
Avoid high temperature and high humidity environments, strengthen ventilation management, and ensure the normal growth of fruiting bodies.
In short, the management measures after the mushroom is produced involve many aspects such as temperature, humidity, ventilation, and light, which need to be comprehensively considered and flexibly adjusted according to the actual situation to ensure the normal growth and high-quality yield of the mushroom.
