Section wood cultivation of Lentinus edodes-- standing wood to produce mushroom

Mushroom wood after a summer and an autumn of careful management, the mycelium will enter the mature stage, before and after the Beginning of Winter can stand up wood, mushroom management.

The signs of the development and maturity of the mycelium of mushroom wood are: there is no big difference between the epidermis of mushroom wood and felling, there is no miscellaneous bacteria, and the bark is close to the bark; it is struck with the back of a knife or fingers to produce a semi-turbid or voiced sound; the bark is soft, the subcutaneous xylem is yellow or yellowish brown, and has the flavor of Lentinus edodes; pressing the bark with your fingers is elastic and rough. And the shape of the tumor protruding, that is, the harbinger of mushrooms, and sometimes there will be a small amount of shiitake mushrooms, commonly known as "news mushrooms". At this time, the mushroom wood can be moved to the mushroom farm to stand up the wood for mushroom production management.

Standing trees must be in evergreen forests, and artificial sheds can be used to increase shade without evergreen forests. Reduce direct sunlight. The method of standing trees is to first insert two stakes, a crossbar in the middle, which is about 60 cm from the ground (the humidity of the mushroom farm can be adjusted), and then lean the mushroom wood on both sides of the horizontal water, arranged in the shape of "human", and the mushroom wood is about 10 cm apart. There is an aisle between the frame and the frame to manage and collect mushrooms. In the standing stage, the mycelium developed and differentiated into the fruiting body stage, and the water content and air humidity of mushroom wood should be increased accordingly. The mushroom wood before the stand should be immersed in water. The immersion place is unlimited, as long as the water quality is clean, and the water invasion time is about 24 hours, so that the water content of mushroom water is about 50%.

Spray water several times a day after standing trees for 3 consecutive days. The humidity of the space is between 80% and 90%. If the external conditions are suitable, the mushroom buds will appear in a few days, and under the conditions of suitable temperature and humidity, the mushroom buds can be harvested in 10 days.

During the period of mushroom production, strengthening water management is a very important work. Too dry or too wet water is not conducive to the formation of primordia and the growth and development of fruiting bodies. If the eye does not rain for a long time, depending on the dry and wet degree of mushroom wood, spray water once every morning and evening, resulting in a certain temperature difference and humidity difference, in order to promote the formation of a large number of fruiting bodies. After the harvest of each batch of Lentinus edodes, until the emergence of the second batch of mushroom buds, water spraying should be controlled to nourish the hyphae. This alternation of promotion and control is beneficial to high yield. If the mushroom wood is too dry and affects the mushroom production, the section of water can be immersed in a pool or stream with lower water temperature for 24 hours, then taken out together, covered with film heat preservation, moisturizing and ventilation once a day, which can promote the occurrence of a large number of mushroom buds. During the period of mushroom production, in order to keep the air of the mushroom farm smooth, we must also clean up the small shrubs and weeds around the tree, and pay attention to the ventilation and light transmission of the small environment.

Before and after the Spring Festival, is the winter mushroom occurrence season, in the management should pay attention to do a good job of heat preservation, cold protection, anti-freezing work; the Beginning of Spring to the Qingming Festival, is the spring mushroom occurrence season, continuous rain, miscellaneous bacteria breeding, in the management should pay attention to do a good job of ditching and drainage around the mushroom farm, and appropriately widen the arrangement distance of the section wood, so as to facilitate ventilation and dehumidification. If it rains for a long time, it can also be covered by a shed to prevent the wood from getting too wet and reduce the breeding of rotten mushrooms and miscellaneous bacteria.

Generally speaking, mushrooms are rarely produced when the monthly average temperature reaches more than 18 ℃ after the Qingming Festival. After mushroom picking, the mushroom wood should be stacked as it is, but as the mushroom wood has lost some nutrients, the wood is not as tough as it used to be, so it should be moved more carefully. The top of the pile still needs to be covered. But there is no need to turn over to allow the mycelium to continue to grow for the next mushroom production year.

Lentinus edodes cultivated in Duanmu generally can produce 3-5 years, less in the first year, rich in the second and third years, and then decreased year by year. The yield of Lentinus edodes is usually calculated by the number of dried mushrooms produced per cubic meter of mushroom wood, and about 10 kg of dried Lentinus edodes can be produced per cubic meter of wood.
