Detailed explanation of the key management techniques for promoting pinning in Agrocybe aegerita (tea tree mushroom)

The method for arranging bags in an outdoor mushroom shed is as follows: prepare the site into a raised bed 30 cm wide and 15 cm high, spread 1 layer of sandy soil on the bed, then spread 2 layers of plastic film, cut open the bag mouths at both ends of the spawn bags and stack them on the raised bed.

The stacking direction of the spawn bags should be consistent with the direction of the doors and windows of the mushroom shed, and bag cutting and bag arranging should be carried out at the same time.

Before opening the spawn bags, disinfect the bags and treat the site for pest control with 34% carbolic acid solution or deltamethrin 3000-fold dilution. Use a sharp knife to cut off the plastic film at the bag mouth along the tying string.

After cutting the bags, as the browning time of the mycelium lengthens and the color deepens, a layer of brown mycelial skin will form on the surface around the bag mouth. Normally colored mycelial skin is brown and rust-brown, glossy, and produces mushrooms normally.

In combination with the color change of the spawn bags, widen the temperature difference continuously for 3-7 days so that the day-night temperature difference reaches 8°C-10°C, until many white granular bodies appear and differentiate into mushroom pins.
