Measures for the Management of Edible Fungi in Autumn

1. Mushroom production management

Pleurotus ostreatus in early autumn: the management focus of this stage should emphasize the word "water". In the conventional cultivation, the water loss of the mushroom bag is serious, so the methods of soaking or injection should be taken to replenish the water in order to obtain higher yield. For Pleurotus ostreatus sown in September, the water balance should be controlled as far as possible to make the mycelium mature and accumulate nutrients to the maximum, so as to lay the foundation for mushroom production in October.

Flammulina velutipes: most of Flammulina velutipes are coming to an end, and about 1/3 of Flammulina velutipes are still coming out. The biggest difficulty in out-of-season cultivation of Flammulina velutipes in cold storage is water management. The humidity of some places of Flammulina velutipes is on the low side, resulting in unsatisfactory yield. There are mainly two major problems: the main position of humidity measurement is 1.5 meters high, while the temperature in the cold storage is high and low, and water is mostly sprinkled on the ground, so that the temperature of the high level is on the high side and the humidity is on the low side; at present, the raw materials are cottonseed shell, which is large shell and short velvet, and the water absorption rate is low (about 30%), and the water holding capacity is poor, which leads to the "congenital deficiency" of water in the bacterial bag.

Pleurotus ostreatus: Pleurotus ostreatus sown in early September, the first tidal mushroom emerged in mid-late October. Pay attention to the effective rehydration of the border bed after mushroom production, in order to benefit the second tide of mushroom.

Auricularia auricula: due to the large temperature difference, whether it is Auricularia auricula or Auricularia auricula, the growth rate becomes slower. At this time, do not spray too much water to prolong the growth period and maximize output.

Lentinus edodes: high-temperature Lentinus edodes has entered the final stage of management. due to the lower temperature and larger temperature difference, the quality of Lentinus edodes will be improved. However, it should be noted that after the last bubble bag is carried out in early October, strengthening low temperature management can produce a number of high-quality fresh mushrooms, and then the shed should be cleaned and sterilized. The bags of low-temperature Lentinus edodes strains can be moved into the shed by the end of October.

2. Germ management

No matter the secondary species or the tertiary species, it should be noted that high humidity is disadvantageous to the strain. Ventilation management should be strengthened, and humidity reduction treatment should be carried out if possible. It is necessary to strictly eliminate miscellaneous bacteria, especially to prevent the occurrence of destructive miscellaneous bacteria such as Alternaria. Once found, it is necessary to slowly cover the contaminated bacteria bag with a plastic bag and move it outside the shed for destruction.

Lentinus edodes: most of the low-temperature Lentinus edodes bacteria have been completed, at this time, we should pay close attention to the temperature change, in line with the principle of "low is not high", adjust the temperature, would rather prolong the time, rather than cause damage to the bag because of the high temperature. When Lentinus edodes in individual areas enter the post-ripening or color-changing period, we should try to lower the temperature, punch holes timely and appropriately according to the growth status of mycelium, and widen the difference between temperature and humidity in order to facilitate the physiological transformation of mycelium.

The routine management of medium and low temperature Pleurotus ostreatus can be done. The bacteria shed was covered with anti-insect net and cypermethrin was sprayed every 3 days to prevent the invasion of mushroom mosquitoes and other pests.

Pleurotus ostreatus: some delayed cultivation of Pleurotus ostreatus can be sown around the middle of October, and the management focus is to prevent the invasion of diseases and insect pests. Spray 300 times liquid every 5 days to prevent the growth of miscellaneous bacteria.
