Management of Lentinus edodes producing mushrooms

After the Lentinus edodes column changed color, the mycelium matured completely and accumulated rich nutrients. Under the stimulation of certain conditions, it quickly changed from vegetative growth to reproductive growth, resulting in fruiting body primordium differentiation and growth and development, that is, entering the fruiting stage.

First, budding: Lentinus edodes belongs to variable temperature fruiting fungi, a certain temperature difference, scattered light and fresh air are conducive to the differentiation of fruiting body primordia. During this period, the mulch on the bed is generally removed, and the temperature of the mushroom greenhouse should be controlled at 10 ℃ 22 ℃, and there can be a temperature difference of 5 Mel 10 Mel between day and night. If the natural temperature difference is small, the temperature difference can be artificially enlarged by means of daytime and night ventilation. The air relative humidity is maintained at about 90%. When the conditions are suitable, the brown bacterial membrane on the surface of 3Mel 4 days will appear white cracks, and mushroom buds will grow soon. During this period, it is necessary to prevent too low space humidity or lack of water in the bacteria column, so as not to affect the formation of fruiting body primordia. When this happens, it is necessary to increase water spraying, each time after spraying water to dry until the surface of the bacteria column is not sticky and slippery, but only damp, covered with plastic film to moisturize. Should also prevent high temperature, high humidity, in order to prevent miscellaneous bacteria pollution, rotten bacteria column. Once there is high temperature and high humidity, it is necessary to strengthen ventilation and reduce temperature and humidity.

Second, the management of fruiting body growth and development period: after mushroom bud differentiation, it enters the growth and development stage. The temperature of fruiting body growth and development of Lentinus edodes strains with different temperature types is different. Most strains can grow and develop fruiting body in the temperature range of 8 ℃ and 25 ℃, and the optimum temperature is 15 ℃, and the fruiting body grows well under constant temperature. The relative humidity of the air is 85%, 90%. As the fruiting body grows up, the respiration is strengthened, and the accumulation of carbon dioxide is accelerated. It is necessary to strengthen ventilation, keep the air fresh, and have a certain amount of scattered light. The beginning of Lentinus edodes sowing in summer is in autumn. The northern autumn is crisp in autumn, the climate is dry, the temperature changes greatly, the bacteria column just begins to produce mushrooms, the water is sufficient, the nutrition is rich, the mycelium is strong, and the focus of management is to control temperature and maintain humidity. If the temperature is high in early autumn, the greenhouse should be covered with sunshade, ventilated and sprayed to cool down; when the temperature is low in late autumn, the temperature should be increased during the day. If the strong light affects mushroom production, you can hang a sunshade net in the greenhouse in mid-air and add a heat preservation curtain at night. When the space relative humidity is low, water spray is mainly sprayed to the wall and space to increase the air relative humidity. When the fruiting body grows until the bacterial membrane has been broken, the cap has not been fully extended, the edge is rolled in, the bacterial fold is all elongated, and changes from white to brown, the fruiting body has medium well, it can be harvested. When harvesting, one hand should hold the bacterial column and the other should hold the base of the fungal stalk and rotate and pull it out. After the whole mushroom is harvested, it should be ventilated for 2 hours in sunny days and dry in sunny days, and 4 hours in cloudy days or high humidity to dry the surface of the bacteria column, and then stop spraying water for 5 min for 7 days. Let the hyphae fully rejuvenate and grow, and the concave hyphae left by picking mushrooms turn white, and then replenish the bacteria column. The method of replenishing water is to first use No. 10 iron wire to pierce a hole in the center of each end of the bacterial column, up to 1 inch 2 of the length of the bacterial column, and then pierce 3 holes equidistant from the side of the bacterial column, then discharge the bacterial column in an immersion pool, put a plank on the bacterial column, press the plank with a stone block, and soak it in clean water for about 2 hours, and it is appropriate to soak the bacterial column in water (the weight of the bacterial column is slightly lower than that before mushroom production). Impermeable bacteria column insufficient moisture, excessive water immersion is easy to cause bacteria column rot, will affect the emergence of mushrooms. After rehydration, the bacteria column will be re-discharged in the border, repeat the previous management method of budding and mushroom production, and prepare the second tide of mushrooms. After the second tide mushroom harvest, or stop water, replenish water, repeat the previous management, generally out of 4 tide mushrooms. Sometimes the water content of the mixture is too large, and the temperature and humidity are suitable when the mushroom is produced. When the mushroom column comes out of the first tide, the water loss is small, and the water can be replenished without immersion, but after the mushroom is harvested in the first tide, the water is stopped for 5 min for 7 days. After the mycelium resumes its growth, it is sprayed with water directly to the fungus column to naturally absorb and increase the water content, and then repeat the previous management of budding and mushroom emergence. When the mushroom is harvested in the second tide, the fungus column is soaked in water. The immersion time can be longer. In the future, every time a tide of mushrooms is harvested, it will be replenished with water.

In the north, the winter temperature is low, the fruiting body grows slowly, and the yield is low, but the mushroom meat is thick and the quality is good. The focus of this season management is to keep warm and increase temperature, increase light during the day, cover grass curtain at night, light a fire if possible, ventilate at noon, and keep the temperature in the greenhouse above 7 ℃ as far as possible. Can spray water to the space, the wall to adjust humidity, less directly spray water on the bacteria column. If the temperature is low and can not produce mushrooms, the relative humidity of the greenhouse should be controlled at 70%, 75%, and the bacteria should be kept to survive the winter.

The climate in spring is dry and windy. At this time, the bacteria column after the emergence of mushrooms in autumn and winter, due to the loss of water and lack of water, the mycelium growth is not as exuberant in autumn. The focus of management is to replenish water to the bacteria column, soak for 4 hours, and often spray water to the wall and space. The air relative humidity is maintained at 85% and 90%. Early spring should pay attention to heat preservation and temperature increase, ventilation should be appropriate, ventilation can be carried out after spraying water, ventilation time should be controlled, and temperature and humidity should not be reduced.
