Agrocybe aegerita has a relatively wide fruiting temperature and a long growth period. Due to the climatic characteristics, subtropical areas can be planted all year round as long as the winter heating problem is handled well. Selection of cultivation sites:

Agrocybe aegerita bag cultivation can be carried out by scaffolding indoors or by building plastic shade sheds outdoors.

1. Construction of plastic shade shed.

it should be built in the east-west direction, and the width should be 2-3 rows of shelves. Generally, the width of the shed is 5-7 meters, the length of the shed is about 25 meters, not more than 4 meters, the edge of the shed is 2 meters high, and the middle height is 3.5 meters. Bamboo or wood can be used as pillars, and bamboo sheets can be used as arches or battens on the roof. A vent tube is set every 3-5 meters on the roof, and doors with a width of 8-1 cm are installed in the north-south direction. Cover the roof and the periphery of the shed with 8-wire thick plastic film, and cover the roof with straw or thatch to play the role of heat insulation and heat preservation. Around the shed, a straw curtain or a sunshade net can be used to shade the sun. Even the mushroom shed is generally 1 meter apart.

2, scaffolding.

Generally, the shelf width is 14-15 cm, and the shelf width without channels on both sides is no more than 7 cm, so it is appropriate to operate it with straight hands. Layer spacing: the distance between each layer is 5-6 cm, and the bottom layer is 2-3 cm from the ground. Set up a shelf every 2 meters, connect the shelves with wooden strips or bamboo stalks, and then discharge bamboo pieces or wooden strips. There should be a passage between each row of shelves, with a general distance of 7 cm. Planting method:

The cultivation methods are mostly clinker bag cultivation and bottle cultivation, and hydroponics has also been successfully tested.

cultivation materials.

Agrocybe aegerita can be cultivated by all agricultural and sideline products rich in cellulose and lignin, such as tea cake powder, sawdust, corncob and cottonseed hull, but the products produced by adding tea seed hull and tea seed cake to the culture medium have natural and special flavor.

hardwood is the best sawdust, such as poplar, willow and other cultivated Agrocybe aegerita with higher yield and faster mycelium growth. No matter which kind of wood chips are used, the old ones are better than the fresh ones. The wood chips should be piled outdoors and exposed to the sun and rain for a long time to make the resin in the wood chips volatilize and the harmful substances disappear completely. The mycelium growth of cultivated Agrocybe aegerita is slow and the yield is low without accumulated sawdust. The cottonseed hull is added to the formula, which is rich in nutrition, high in protein and fat, and the produced culture medium is well ventilated, which can increase the yield by nearly one time.

mix and bag.

firstly, the cottonseed hull is crushed into large grains of rice, and then it is soaked in 1-2% lime water for 1-14 hours a day. After it is picked up, it is added with other culture materials, mixed evenly and bagged. The tea seed cake needs to be crushed into powder, mixed with other culture materials and bagged for sterilization. All kinds of culture materials should be 8-9 mesh, and the old material is better than the new material. The cottonseed hull should be stirred with water one day in advance, piled up and covered with film to make it absorb water evenly, and then the auxiliary materials should be added the next day to mix well, and the water content should be controlled within 7-75%. After the materials are mixed, they can be bagged (the bag size is 32×15 or 4×17-18cm, made of polypropylene film with 5 silk meters), which should be smooth and uniform when bagging, and should be packed tightly, then tied tightly with a binding line and sent to a sterilization stove for sterilization.

improve bag-making yield.

the first is the quality of culture materials. The culture material should be fresh and mildew-free, and the sawdust should be ripened and sieved. The water content of the culture material should be appropriate, and the degree is that there is water stain on the fingers but it does not drip.

the second is the production of bacterial bags. Cotton seed hulls and sawdust should be pre-moistened 24 hours in advance and added with lime for accumulation and fermentation, then wheat bran should be added, and the time for mixing and bagging should not exceed 5 hours.

the third is disinfection and sterilization. Bag the materials into the normal pressure stove, generally 25-3 bags per stove, not too much. During sterilization, "attacking the head, controlling the center and protecting the tail" shall be achieved, so that the time for heating to 1℃ shall be shortened as far as possible, and the temperature shall be kept for 16-18 hours after reaching 1℃, so as to achieve complete sterilization.

the fourth is strain culture. Agrocybe aegerita is sensitive to light and temperature, and the strain culture should be carried out at a relatively constant temperature and in the dark, and the temperature should be controlled at 22-26℃, and the culture room should be inspected every 1 days to remove the contaminated strain.

fifth, inoculation in bacterial bags. After sterilization, the material temperature is cooled to below 3℃, and then it is put into an inoculation box for inoculation. Minimize the damage of the fungus bag.

scientifically arrange the bag-making season.

Agrocybe aegerita mycelium can grow at 5-35℃, and the optimum temperature for fruiting body differentiation is 22-26℃. When the temperature is lower than 2℃, the fruiting body grows slowly, the tide turns slowly, the stipe is short and the yield is low. When the temperature is higher than 28℃, the fruiting body grows fast and opens easily, which affects the quality. The middle and late May and the middle and late September in Gaochun County are most suitable for the formation and growth of Agrocybe aegerita fruiting bodies. Pushing forward 55-6 days is the reasonable bag-making period, and it is generally arranged in the middle and early March and the middle and early July.
