Production of Agaricus bisporus in cold storage, temperature and humidity It is easy to control, can be produced all year round, and has high output: up to -kg per square meter. Good quality: the mushroom body is round, white and tender. The fruiting period is short, the investment is small, the results are quick, and the benefits are considerable. The main production technical points are as follows:
1. Cold storage transformation
.Building mushroom beds: generally bamboo and wood structures. Bed frames are generally angle iron or cement structures. The length of the mushroom bed is not limited, the baffle height is cm, the height between floors is - cm, the bottom floor is about cm from the ground, and the width of the aisle is not less than cm. Generally, a cold storage can be built with - floors.
.Ventilation facility renovation: Add an air filter device to the original vents, and change the air inlet of the refrigerator to be used for both extracting fresh air and circulating air in the cold storage.
2. Material preparation and fermentation
. Material preparation: based on the cultivation area, 3 kg of wheat straw, 3 kg of wet chicken manure, kg of gypsum, kg of urea, kg of lime, and kg of superphosphate.
. Pile construction and primary fermentation: 3 days before building the pile, pre-wet the wheat straw, add lime at the same time, and then pile a layer of wheat straw and a layer of chicken manure. The wet chicken manure should be beaten into a paste and mixed with urea. The width, height and length of the pile are not limited. The pile should be neat, the sides should be vertical, the top of the pile should be turtle-shaped, and the water in the pile should be divided. The temperature of the stockpile is measured several times a day, and the ideal temperature is ℃-℃. After about a few days, turn the pile for the first time, add superphosphate evenly, and change the pile to a width with the height unchanged. After about a day, turn the pile for the second time and add the gypsum evenly. This time, the moisture should be adjusted appropriately. The moisture should not be too large. The width should be reduced to . and the height should remain unchanged. When turning the pile for the third time, the dryness and wetness of the binder determine whether to add water. The water content should be measured at this time. If it is low, lime or lime water should be used to adjust it. Each time you start turning the pile, the temperature of the material should drop. The specific number of turning over the pile should be flexibly controlled according to the temperature of the pile and other conditions. It is generally one time and ends in about a day.
.Secondary fermentation: The best effect is to use steam to raise the temperature. That is, transport the culture material to the mushroom room that has been strictly disinfected and sterilized, and lay it on the bed frame from top to bottom, so that the room temperature reaches ℃ and the material temperature reaches ℃. - ℃, keep it for - hours, then the material temperature drops to ℃, keep it for an hour, and then lower it to ℃ every day. When it drops below ℃, you can sow. The fermented culture material has a fragrance, the forage will break when you pull it, and the manure will be even. The material is loose, the moisture is -, the value.
3. Sowing
Transport the fermented material directly to the mushroom bed, spread it out and compact it to a thickness of -cm. When the temperature of the indoor secondary fermentation drops to about ℃, you can sow. Mixed sowing can be used. Two bottles of bacteria are packed per square meter, of which 3/ is put into the material and / is sprinkled on the surface. Hole sowing can also be used: the spacing between rows and plants is cm, and the hole depth is more than cm. Most of the strains are sown into the holes, and a small part is spread on the surface and compacted. The strains and the culture material are in close contact. The amount of seeds is the same as above. After sowing, cover it with plastic film and spray formaldehyde to disinfect the environment. After an hour, ventilate a little to remove the smell of medicine. There is no need for large ventilation or water spraying within 3 days after sowing. Ventilate after 3 days and indoors every day. There must be fresh air, the temperature should be controlled at ℃ - ℃, and the relative humidity of the air should be -. Generally, when the mycelium grows to /3 in about a day, it can be covered with soil.
4. Covering with soil and fruiting
Covering with soil: Select the clay below the surface of the ground. Excavate the soil and expose it to the sun, crush it into particles with a diameter of .cm, then mix and add fly ash and lime, and then Use formaldehyde and spray, cover with plastic film, turn over the soil particles to remove the smell, and then cover with soil. Covering soil requirements: good water holding capacity and aeration, value. The thickness of the covering soil is 3.cm. It is best to cover all the soil at one time and level it. At this time, it is advisable to grasp the moisture into a ball and disperse it when it lands on the ground. In the next 3 days, gradually adjust the bed soil to a saturated state, but do not let water leak into the material. Mycelium will grow out of the soil in about a week. When the mycelium grows out of the soil, rake it (scratch the bacteria). The raking depth should be .cm away from the culture material. The raking should be fine and flat, which is conducive to neat fruiting. After 3 days, the room temperature should be lowered to ℃ to promote the formation of fruiting bodies.
.Fruiting: This stage requires the relative air humidity to be -, the temperature is about ℃, and the material temperature cannot exceed ℃. When white fruit bodies the size of rice grains are formed on the surface of the covering soil or under the soil layer, spray water must be sprayed if it is dry. Spray lightly, with small amounts and fine droplets, or only spray water into the air and walls. When the fruiting bodies grow to the size of soybeans, slightly increase the amount and frequency of water spraying. Depending on the density of the mushrooms, spray more for more mushrooms and less for less mushrooms. Generally, no water is sprayed during the peak period of mushroom picking. Indoor air circulation should be carried out immediately after each water spray.
5. Mushroom picking
When the diameter of the mushroom cap reaches more than cm, it can be harvested according to different grade standards. One tide can be harvested in each cycle, and mushrooms can be harvested continuously for one day per tide. The mushrooms can be harvested on the next tide in about days. After each harvest of mushrooms, the bed should be cleaned, and the holes left by the mushroom picking should be filled with sterilized soil, and sprayed with water again to promote the change of mushroom tide.
Each production cycle lasts for a month, and the next cycle of fermentation begins one month before the fruiting ends. After fruiting, clean up the old culture material and keep it away from the mushroom house. This culture material can be returned to the fields as high-quality organic fertilizer. Then the mushroom house is thoroughly disinfected to prepare for the next production cycle. Anhui Jinxue Refrigeration Equipment Co., Ltd.
