Key cultivation techniques of high-grade hericium Erinaceus

Fourth, put bags in the field to induce directional mushroom production.

Hericium Erinaceus is an aerobic fungus, the cultivation place requires fresh air, and the field mushroom shed is ideal. After about 25 days of indoor cultivation, the mycelium matured, and then changed from vegetative growth to reproductive growth. Hericium Erinaceus usually begins to show primordia and differentiate into fruiting bodies before the mycelium is full. Therefore, it is necessary to pay attention to observation, move the bacteria bag to the field in the wild shed in time, and scratch the surface of the original strain block to induce the orientation and neatness of mushroom.

At present, there are three common ways to swing the field: the first one is to build 4-to-5 floors and intensive three-dimensional cultivation. The second kind sets up the frame on the first floor and discharges 2 bags. 1 bag lying on the ground, the mouth of the hole facing up, 1 bag lying on the shelf, the mouth of the hole downward. The third is simulated open-field cultivation of Lentinus edodes. Lean against the bag, or build ridges on both sides, put the single bag lying flat, and the mouth of the hole goes down.

Compared with the above three ways, the first one, the space utilization rate is high, forming three-dimensional, but the moisture retention is poor, it is easy to form bald mushroom and atrophic mushroom. The latter two kinds of mushroom bodies form spiny hairs, and the color is whiter. Because the bristles of hericium Erinaceus have obvious "geopotential" growth, but in the rainy season, when there is stagnant water in the border bed and poor ventilation, rotten mushrooms are easy to appear. Lean on the bag out of the mushroom period, do not easily invert the bacterial bag, otherwise cause spiny hair not homeopathic growth, into deformed mushrooms.

Fifth, control ecology and promote the improvement of grade

In order to obtain high-grade products, the management of the following aspects must be strengthened in the growing stage of hericium Erinaceus.

1. After adjusting the temperature, the temperature of the bacteria bag should be reduced from the original temperature to the optimum temperature of 16 ℃ ~ 20 ℃ in the mushroom emergence period. In a suitable temperature environment, from small buds to mushrooms, it can be harvested in 10 to 12 days. When the temperature exceeds 23 ℃, the fruiting body develops slowly, which will cause the stalk to proliferate continuously, and the mushroom body will become cauliflower-like deformed mushroom, or skinhead mushroom without spiny hair. More than 25 ℃ will also cause mushroom body atrophy. Therefore, in the stage of mushroom emergence, special attention should be paid to controlling the temperature. If the temperature exceeds the prescribed temperature, four measures can be taken: ① space to increase atomized water. 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.

two。 Hericium Erinaceus is a kind of aerobic fungus, if poor ventilation, excessive carbon dioxide deposition, stimulate the continuous branching of the stalk, inhibit the development of the center, there will be coral-like deformed mushrooms. Under this kind of saturated humidity and still air, it is more likely to become deformed mushroom body, or mixed bacteria reproduction pollution. For this reason, the film should be ventilated for 30 minutes at 8 am every day, and the fruiting body should be ventilated in the morning and evening every day when it grows up, and the ventilation time should be extended appropriately. But avoid the wind blowing directly on the mushroom body, so as not to shrink. (to be continued)
